12:00 AM dioz: do the layput for the tee on that intersect
12:02 AM dioz: layout
12:02 AM dioz: sheet metal duct
12:02 AM dioz: 24 gauge
12:02 AM dioz: with a 1/4 in groove seam.
12:02 AM LeelooMinai: Well, first of all, CADs have sheet-metal modes - never used them though.
12:02 AM dioz: hah. also the difference between a 70%er and higher 80's is knowing how it works without something else figuring it out for you
12:02 AM LeelooMinai: So not sure how that mode works, but I would still do what you do in 3D CAD probably.
12:03 AM dioz: i mean we could probably also use sinusoidal regression equation to determine on-center 90 degree intersects....
12:03 AM dioz: but thay involves math bro
12:04 AM dioz: i got tin snips and some dividers and a tape measure and a scratch awl and some metal masters
12:04 AM dioz: wiss
12:05 AM dioz: and some stanley i guess
12:06 AM dioz: i like wiss though cause i just take em to the local joint and the swap em out for me
12:07 AM dioz: i cut lots of 16 gauge angle iron by hand
12:07 AM dioz: so i snap them lots
12:08 AM dioz: i have broken 2 sets of bulldog aviation snips.
12:08 AM dioz: bulldog compound action snips or whatever you wanna call em
12:09 AM dioz: not pattern snips like a wiss w5n
12:11 AM dioz: this text book says "the most common type of hammer is a 16oz hammer"
12:11 AM dioz: 16oz what?
12:11 AM dioz: framing? finishing? machinist? rivetting?
12:11 AM LeelooMinai: half a kilo?
12:12 AM dioz: does it have a hickory fucking handle?
12:12 AM XXCoder: 16 oz golod hammer
12:12 AM XXCoder: gold
12:12 AM dioz: trade school is so awesome and so gay at the same time
12:19 AM dioz: when you out far from the shop and the unicorn building project that never needa custom fitting ends up needing a custom fitting... you be like: "lemme break out my portable plasma table here"
12:20 AM dioz: or wait. you're a union guy!
12:20 AM dioz: jk jk
12:20 AM dioz: calm doen
12:20 AM dioz: down
12:21 AM LeelooMinai: Well, no, I would probably make a tube from paper to scale, pierce it a metal tube with sharp edges and unroll the first one:p
12:22 AM dioz: in a situation where you got two parallel duct that are offset by 45 inches what length intesect do you need?
12:22 AM dioz: with 45 degree elbows i mean
12:23 AM dioz: regardless what i'm sayin is there's a djfference between the brothers thst can tell you the empiricals vs. dude that does it with software
12:24 AM LeelooMinai: Yes, the dude with software scales better? :)
12:24 AM Crom: intersect is what 1.33?
12:24 AM dioz: haha. you're gonna make me obsolete :(
12:25 AM dioz: (1.1414 xoffset) -2 (.414x (clr) centre line radius this is the formula
12:25 AM dioz: example degree of elbow: 60=.577
12:25 AM dioz: 45=.414
12:25 AM dioz: 30=2.00
12:25 AM Crom: takes me back to bending emt
12:25 AM dioz: oops. 1.1414 should be 1.414
12:26 AM Crom: that's it 1.414 I'd have to look at the tables for 1.33
12:26 AM LeelooMinai: That's probably sqrt(2) you are seeing there.
12:27 AM dioz: yah
12:28 AM dioz: for example a duct of 6x12 would have a clr (if moving on the long side with a finished line radius of 3 would be 6 clr
12:28 AM Crom: ahhh 49 degrees 1.325 actually...
12:28 AM dioz: radians?
12:30 AM Crom: I had a 49 degree bend... offset length was 1.325 of distance
12:32 AM dioz: this text book has a math error. it says in the word problem 1/4 inch bend radius on a piece but in the equation it uses 1/8 in
12:35 AM Crom: running emt up the side of a feed chute... 49 degrees didn't left the material build up on the chute... anything less than 49 degrees you get clumps build up on the chute
12:35 AM dioz: fuck man who proof reads this shit?
12:35 AM dioz: clumps
12:35 AM XXCoder: everyone and mother
12:35 AM XXCoder: I don't know why mothers are not counted in "everyone" but whatever
12:35 AM roycroft: because they are the mothers of everyone
12:35 AM dioz: seriously though... sheet metal made me understand so much about properties of metal and bend radius and how to work with steel
12:35 AM Crom: stretch on bends can really foul you up
12:36 AM dioz: bounce back too
12:36 AM dioz: even if you're coining you're going to get "minimal" backbend
12:36 AM Crom: had a Mechanical engineer buddy... he gave up trying to figure it mathmatically and just asked the old school journeyman for his cheat sheet...
12:37 AM dioz: it's written on the press. to determine v die size is 8x material width
12:37 AM dioz: air bending w/ 80 to 88 degree dies
12:37 AM dioz: takes less tonnage
12:37 AM dioz: coining with super hard dies requires more tonnage
12:38 AM Crom: the cheet sheet had calculations for every suppliers sheet goods and thicknesses
12:38 AM dioz: they call a metals ability to bend "ductility"
12:38 AM dioz: bend and be worked i should say
12:38 AM dioz: no way
12:38 AM dioz: it couldn't
12:39 AM dioz: mill certs for batch to batch change
12:39 AM dioz: no way you're getting the "exact" fucking same piece of metal
12:40 AM dioz: the sheet might be close
12:40 AM dioz: but you're gonna fuck with a few thousandths of an iche i'll bet
12:40 AM Crom: true... but the cheat sheet was closer than he could get mathmatically..
12:40 AM XXCoder: all raw materials always has certain tolence range
12:40 AM XXCoder: say 2"x2"x.125" +- .1"
12:41 AM XXCoder: thickness +- .005
12:41 AM dioz: oh yah totally. specially becayse of coatings
12:41 AM dioz: like turn coats and shit
12:41 AM dioz: tirn?
12:41 AM dioz: i think it's turn
12:41 AM Crom: he was off like 0.013 on 16guage and using the cheat sheet he was within 0.004
12:41 AM dioz: terne
12:42 AM dioz: like galv on iron is still a coating thay's gonna add some thickness of material
12:43 AM Crom: they were making cabinets for electrical gear...
12:43 AM dioz: well yah depends if yoj're bottom bending or coining or air bending too though...
12:44 AM dioz: whatever
12:44 AM dioz: stand behind a hydraulik press for a few months
12:44 AM dioz: tell me how it works
12:44 AM Crom: I like my fingers no thanks
12:44 AM dioz: sloppy
12:44 AM XXCoder: machinist who retire with all fingers did good job
12:45 AM dioz: lol
12:45 AM dioz: i guess so.
12:45 AM dioz: my old man is a mechanic
12:46 AM dioz: he's shown me some good cuts but not so much now that he's older
12:46 AM dioz: seems to have calmed down a lot tbh
12:46 AM dioz: get mad at a piece of steel
12:46 AM dioz: it ends up hurting you more thwn you can hurt it
12:47 AM dioz: i got 16 stitches my 4th day bangin tin
12:47 AM dioz: could have been a tendon
12:47 AM dioz: smartened the fuck up after that
12:47 AM dioz: don't put your fingers where tou wouldn't put your dick
12:48 AM XXCoder: my worse so far is big alum block slipped and took my hand holding it up with it, and part below it cut into my wrist
12:48 AM dioz: wait... i think i got the pic
12:48 AM XXCoder: 4 sitchesm and looks like sucide attempt
12:48 AM XXCoder: lame one but nevertheless
12:50 AM dioz: check this out
12:50 AM dioz: http://imgur.com/sifmhWJ
12:52 AM dioz: i love talkin about war wounds
12:52 AM dioz: chicks always ask me about the big gash on my head
12:52 AM dioz: cause i keep my hair down and there's a big scar
12:52 AM dioz: i let my buddy tell the story
12:52 AM dioz: he weighs about 300 pounds
12:54 AM dioz: fuck this guy once said to me.... "when i get mad i punch things". showed me his knuckles and they fuvked
12:55 AM dioz: i was like "psycho"
12:55 AM dioz: no new friends
12:55 AM XXCoder: so that 300lb guy can have sex too? :P
12:56 AM dioz: i imagine he can
12:56 AM dioz: fat bitches need lovin too
12:56 AM dioz: hey
12:56 AM dioz: before i go to bed
12:57 AM dioz: can someone tell me the difference between jog mode and auto? typically.
12:57 AM XXCoder: "auto"?
12:57 AM Crom: I think that's when it's running g code
12:57 AM XXCoder: jog is you move machine by various methods like keyboard or pendant
12:57 AM XXCoder: yeah most likely
12:58 AM Crom: jog mode is 'manual
12:58 AM dioz: auto usually completes the full motion of the action
12:58 AM XXCoder: most machine it's "mem" or memory
12:58 AM dioz: jog will only progress through the action if the "button" is being pressed
12:58 AM XXCoder: theres also MDI where you input gcode yourself
12:58 AM XXCoder: say t21m6;
12:58 AM XXCoder: it changes tool
12:58 AM dioz: it's a safety thing
12:59 AM XXCoder: depends on achine
12:59 AM XXCoder: most machine I ran dont have that
12:59 AM dioz: not really...
12:59 AM XXCoder: just change to jog mode and start using jog wheel after selecting axis.
12:59 AM dioz: oh you're talking about the process of making the item?
12:59 AM dioz: like... digitally?
01:00 AM dioz: or the process of the item being created?
01:00 AM XXCoder: no
01:00 AM XXCoder: its usually used for say setup find x y z
01:01 AM dioz: okay
01:01 AM XXCoder: manual gcode is mdi
01:01 AM dioz: oooh i get you
01:01 AM dioz: i feel dumb now
01:02 AM dioz: okay gnight
01:02 AM XXCoder: later
01:10 AM Crom: still trying to get the courage to chuck up the ball screw and start whittling on it in the lathe
01:10 AM XXCoder: orer cheap sub-500mm ones from chinese and learn with those first?
01:10 AM Crom: got a 300mm
01:11 AM Crom: need to cut 22mm off, to hold the bearings in the nut, then I can start profiling it
01:12 AM Crom: oh, and I have to bore a hole in the 22mm section so I can butt that section to the completed ball screw
01:13 AM XXCoder: fusing 2 ballscrews together to make longer one?
01:15 AM Crom: not... the 300 needs to be shortened to 265mmish, but there is a 8mm diameter pilot shaft at the top and a short one on the bottom where it goes into the guide bearing., to put the nut back on, I have to butt the threaded section together. so I need a hole to stick the rebated section into
01:16 AM Crom: ---=======-
01:16 AM XXCoder: ahh
01:17 AM Crom: l== is the ballscrew thread -- is the rebated to 8mm diamter sections
01:17 AM IchGucksLive: morning from germany
01:18 AM XXCoder: hey
01:21 AM Crom: ==-== all the bearings would fall out. ==== with the ==- inside the =##= nut and the short
01:21 AM IchGucksLive: Crom: are you making your own ballscews
01:22 AM XXCoder: hes modifing it
01:22 AM IchGucksLive: the tread
01:23 AM IchGucksLive: ore only the ends
01:23 AM XXCoder: crom can explain it better
01:23 AM Crom: got a 300mm ball screw from ebay... now I'm putting the rebated areas for the guide bearings...
01:24 AM IchGucksLive: ok
01:25 AM Crom: and I need to make a parking section to hold the nut while I'm working on the ball scew and that holding section needs a hole bored in it, so I can butt up the threads and transfer the nut from the holding section to the ball screw
01:25 AM XXCoder: so its temp hold thing?
01:26 AM XXCoder: to keep balls inside nut
01:26 AM Crom: yep
01:27 AM XXCoder: i was thining perment that was what confused me a little
01:28 AM Crom: I need to see if I can have the nut inside the 4 jaw behind the jaws... if I can then I don't need a parking section
01:35 AM IchGucksLive: Crom: duck tape
01:39 AM archivist: most unsuitable for the nut to retain the balls
02:05 AM IchGucksLive: ok just in from my brother the maschine seams to run http://heimwerkermarkt-tretter.de/holzcnc.jpg
02:05 AM IchGucksLive: This mashine is build only with a simple drill
02:05 AM XXCoder: looking
02:05 AM XXCoder: lol
02:05 AM IchGucksLive: and of cause a good wood saw
02:05 AM XXCoder: I planned somkething like that with my ballscrews and SBR kit
02:05 AM XXCoder: ened up not using those.
02:06 AM IchGucksLive: oh if you got little more money go ALLOY
02:06 AM XXCoder: how do that machine protect SBR, all exposed like that
02:06 AM IchGucksLive: its more easy then that in wood
02:06 AM IchGucksLive: XXCoder: you can mount the X sbr under the table
02:07 AM XXCoder: I suppose but I will not use em anyway as I have metal cnc router now anyway
02:07 AM IchGucksLive: or hidden on the side
02:08 AM IchGucksLive: the total mashine cost at 900x650x350mm Workroom is 850 Euros
02:08 AM IchGucksLive: without tool
02:09 AM XXCoder: yeah evenually want bigger but no room in home for it anyway
02:09 AM IchGucksLive: with the supports on the Y frame it is realy stable will try out Alloy milling if i can get access
02:10 AM XXCoder: yeah somewhat shallow cuts
02:10 AM XXCoder: I'm niot too sure what mm/s and rpm on cutting alum
02:10 AM IchGucksLive: XXCoder: he fighted for eatcxh mm of workroom and at the end he (lost on Homing )
02:11 AM IchGucksLive: 60
02:11 AM IchGucksLive: 60/100mm/min RPM calc
02:11 AM IchGucksLive: i use 8krpm on a 6mm bit
02:11 AM IchGucksLive: workes fine
02:12 AM IchGucksLive: on 10x1mm cut rate
02:12 AM IchGucksLive: ok i need to go
02:12 AM IchGucksLive: see You
02:13 AM XXCoder: 10x1mm hmm think thats depth
02:13 AM XXCoder: oh well
02:20 AM Deejay: moin
02:21 AM XXCoder: hey
02:49 AM Crom: WOOO HOOO!!!! Spanning tree is actually working! I can see every computer on the LAN
02:51 AM Crom: had a problem with router 250... wlan0 and wlan1 were on lan and wan... now on lan only... using openwrt (LEDE Porject)
02:51 AM Crom: it's an inside router so everything is on the same bridge...
03:06 AM * Loetmichel just went to the mechanic on the commute to work. He says he will try to get a second BMW 318i from a similar build year to replace the engine (that threw a ron on me saturday) and the suspension. And that that will NOT be cheap... thats what you get if you buy a BMW convertible for 900eur. :-(
03:12 AM Loetmichel: s/ron/rod
03:29 AM dfgg_ is now known as dfgg
03:36 AM Goodlord: learning g code haha
03:54 AM archivist_herron: it is good for you
03:55 AM XXCoder: yeah thats why its named G code. as in good code
03:58 AM Goodlord: archivist i had a thought about 4th axis wrapping and so on
03:59 AM Goodlord: dont know if you saw my description yesterday
03:59 AM archivist_herron: yes
03:59 AM Goodlord: so that is basically the right idea?
04:00 AM archivist_herron: well I saw some of it, making table legs
04:00 AM Goodlord: yes
04:01 AM Goodlord: if a draw the table leg - or any cyclinder with contours unwrapped so to speak, in the xy plane
04:01 AM archivist_herron: relatively simple to write code for that, could be harder to get CAM to do it :)
04:02 AM archivist_herron: I would be thinking in lathe terms when machining
04:02 AM Goodlord: im just looking at g code, i noticed in your script you had some loops running?
04:03 AM archivist_herron: yes that is a gutting a gear
04:03 AM Goodlord: im gonna have another quick look at it now
04:03 AM Goodlord: was just thinking for stepping A a loop would be useful
04:04 AM archivist_herron: you might want to make a spiral on a leg
04:04 AM Goodlord: if X = 0, A=A+1 etc
04:04 AM Goodlord: yes spirals as well
04:04 AM archivist_herron: or carved effect
04:04 AM Goodlord: right exactly
04:05 AM Goodlord: i can get any old cam software to make a toolpath for the unwrapped part
04:05 AM Goodlord: in lines along xy
04:05 AM Goodlord: any part no matter how much carving
04:05 AM archivist_herron: cam wont do spirals nicely
04:06 AM Goodlord: well, again, do it unwrapped, imagine a sheet of paper with lines drawn at 45 degrees along it, roll that up into a tube - you get a spiral
04:07 AM Goodlord: the stepping of A during cutting rolls the flat design into a cylinder
04:07 AM archivist_herron: yes but, they dont join loop to loop nicely
04:07 AM Goodlord: ok how do we do it then?
04:08 AM XXCoder: can always graph spirl on cylinder then do math to figure how unwrap it
04:08 AM archivist_herron: write the spiral direct into a line of gcode
04:08 AM XXCoder: I bet it almost looks like arctan graph on fglat sheet.
04:08 AM archivist_herron: XXCoder, I am trying to untrain that bodge!
04:08 AM Goodlord: same as thread cutting basically
04:08 AM archivist_herron: yes
04:10 AM archivist_herron: set of pics of a worm being cut http://www.collection.archivist.info/searchv13.php?searchstr=merlin+worm
04:11 AM archivist_herron: the main cut is a single g1 line
04:13 AM archivist_herron: because it is a shaped cutter, the axis is at an angle (head at an angle is equivalent)
04:13 AM Goodlord: that should be within my abilities lol
04:14 AM archivist_herron: I cant post the url for the gcode for that from here
04:14 AM Goodlord: im only working with wood so plenty of profiles available off the shelf cutter wise
04:15 AM archivist_herron: when doing a spiral one needs it at the helix angle
04:19 AM Goodlord: well i need to get familiar with g code first i guess
04:23 AM archivist_herron: you wont care about helix angle if milling with a ball nose cutter
05:16 AM jthornton: morning
05:17 AM XXCoder: hey jthornton
05:17 AM XXCoder: check this out https://www.youtube.com/watch?v=SQdn_TvryeE
05:17 AM XXCoder: er wrong one but good also
05:17 AM XXCoder: ah its https://www.youtube.com/watch?v=JmyJeo4Ewpk jthornton
05:56 AM Apothus: Is there a torrent file for the .iso?
05:58 AM jthornton: not that I know of
06:01 AM Apothus: shame, would take some of the server load off and speed up what is proving to be a slow download :P
06:02 AM XXCoder: not only slow but fat also
06:02 AM XXCoder: it sucks
06:04 AM Apothus: would anyone object to a torrent being created and shared?
06:14 AM jthornton: the chicks are getting restless
06:15 AM XXCoder: remember that movie
06:15 AM XXCoder: dont be too evil man. ;)
06:15 AM XXCoder: or you will end up blowing p your chicken pies
06:15 AM XXCoder: machine
06:20 AM jthornton: first night with lights out they just slept on the floor, second night they had it figured out and slept on the roost
06:43 AM jthornton: what movie was that?
06:44 AM TurBoss_at_cnc: where ar stored the active GCodes?
06:44 AM TurBoss_at_cnc: how i can reset them
06:44 AM TurBoss_at_cnc: ?
06:47 AM jthornton: modal G codes are changed when you issue a different G code in that modal group
06:48 AM TurBoss_at_cnc: I have G10 I wan't to remove it
06:48 AM TurBoss_at_cnc: or disable
06:49 AM jthornton: G10 L?
06:49 AM TurBoss_at_cnc: sorry what L
06:49 AM TurBoss_at_cnc: I don't now much Gcode
06:50 AM TurBoss_at_cnc: L0?
06:50 AM jthornton: look in the documents for G10 L... L1, L2, L10...
06:51 AM TurBoss_at_cnc: ok thankjs
06:51 AM TurBoss_at_cnc: *thanks
06:51 AM archivist_herron: he is not javascript!
06:51 AM jthornton: lol
06:51 AM TurBoss_at_cnc: :)
06:54 AM archivist_herron: I have a hatred of the stuff it is slowing many websites to a crawl
06:58 AM TurBoss_at_cnc: the problem I have is that when I issue a g54 a popup is shown
06:59 AM TurBoss_at_cnc: Line with G10 does not have L1, L10, L11 ...
06:59 AM TurBoss_at_cnc: my program does not have any G10
07:02 AM archivist_herron: are you writing the program or using some cam with the wrong dialect
07:02 AM TurBoss_at_cnc: I opened a freecad path
07:03 AM TurBoss_at_cnc: but now i'm opening a working code
07:03 AM TurBoss_at_cnc: at least worked
07:15 AM TurBoss_at_cnc: I can't issue G54
07:15 AM TurBoss_at_cnc: the popup is shown...
07:16 AM TurBoss_at_cnc: the program I'm trying to open worked
07:37 AM TurBoss: G10 L1 Pn
07:37 AM TurBoss: trying
07:46 AM TurBoss_at_cnc: ok g92.1
07:48 AM TurBoss_at_cnc: no :,,(
07:48 AM TurBoss_at_cnc: :D
08:19 AM gregcnc: what message is shown when you g54?
08:20 AM TurBoss: one second please
08:21 AM TurBoss_at_cnc: If I click on regulart offset this is shown
08:22 AM TurBoss_at_cnc: Near Line 0 of /path/to/file.ngc :Line with g10 does not have L1, L10, L2 or L 20
08:24 AM gregcnc: what is "regular offset" you talk about
08:27 AM dioz: not irregular
08:27 AM gregcnc: because there is an irregular offset?
08:28 AM dioz: there are regular and irregular expressions
08:29 AM TurBoss: is a AXIS button
08:29 AM dioz: *shrug*
08:29 AM TurBoss: it sets g54 for the active axis
08:30 AM gregcnc: some translation of touch off?
08:30 AM TurBoss: no
08:31 AM TurBoss: touch off is next to it
08:31 AM nallar is now known as Ross
08:31 AM TurBoss: http://i.imgur.com/djTRCz9.png
08:32 AM TurBoss: I forgot to say that I'm running 2.8
08:35 AM archivist_herron: who did that translation!
08:35 AM TurBoss: no idea but is half done
08:35 AM gregcnc: anyone know if that button changed in english? it's always been touch off. Anyway, something seems broken as it should bring up a dialog box to enter a number for the axis
08:38 AM gregcnc: that button does not issue "G54" so that we are clear
08:38 AM TurBoss: description tooltip says that
08:41 AM gregcnc: translation is bad
08:43 AM gregcnc: but I don't know why the button doesn't work as it should
08:56 AM archivist_herron: probably miss understanding what it does
09:27 AM nallar is now known as Ross
09:41 AM TurBoss: http://i.imgur.com/5k5vU0f.png
09:42 AM TurBoss: this is the window
09:43 AM gregcnc: that pops up when you click "regular offset"?
09:43 AM TurBoss: yes
09:43 AM TurBoss: there is no g10 in the "gato.ngc"
09:44 AM gregcnc: is this the standard axis sim?
09:44 AM TurBoss: this is the real machine
09:50 AM gregcnc: anyone know if touch off is broken in that version of pre?
09:51 AM nallar is now known as Ross
09:51 AM gregcnc: is thre any reason you're not using a stable version?
09:52 AM TurBoss_at_cnc: no just curious
09:52 AM TurBoss_at_cnc: could this be abug?
09:54 AM TurBoss_at_cnc: is there a way to restore the active gcodes?
09:54 AM gregcnc: i'm fairly certain touch off uses G10 in the background, and something is broken
09:54 AM gregcnc: https://www.google.com/search?q=axis+touch+off+macro&ie=utf-8&oe=utf-8#safe=off&q=linuxcnc+axis+touch+off+macro
09:55 AM gregcnc: oops not that
09:55 AM TurBoss_at_cnc: but I use g54 to define the stock
09:55 AM gregcnc: https://github.com/LinuxCNC/linuxcnc/issues/269
09:55 AM TurBoss_at_cnc: oh
10:06 AM IchGucksLive: hi all
10:08 AM IchGucksLive: TurBoss_at_cnc: you realy go to the edges Try to
10:08 AM TurBoss_at_cnc: sorry, what do you mean?
10:09 AM IchGucksLive: are you doing frond end Development stages as you use the 2.8 not recomended for real mashines
10:09 AM TurBoss_at_cnc: ah
10:09 AM IchGucksLive: there is up in this irc frame the Version to be used in the mashine workarea
10:09 AM TurBoss_at_cnc: ok
10:10 AM IchGucksLive: this minimises all the effects of comp traj errors and lots of trouble you wont want to be in
10:10 AM TurBoss_at_cnc: ok
10:11 AM IchGucksLive: and remember the last week as all did confront me on how to start gcoding on low level
10:11 AM IchGucksLive: that is how the thing works
10:12 AM IchGucksLive: if you give your control((Mashine all the needed info the best outcome you can expect
10:12 AM IchGucksLive: TurBoss_at_cnc: did you lok on the G10 Video i made to see how it when it acts
10:12 AM TurBoss_at_cnc: no
10:13 AM TurBoss_at_cnc: checnking
10:13 AM gregcnc: he's not using g10
10:13 AM IchGucksLive: Thanks
10:14 AM IchGucksLive: gato.ngc is this public to get a look int
10:14 AM IchGucksLive: o
10:14 AM TurBoss_at_cnc: yes
10:14 AM TurBoss_at_cnc: sek
10:16 AM TurBoss_at_cnc: http://dpaste.com/1FFVJVH
10:16 AM TurBoss_at_cnc: gato.ngc that used to work
10:17 AM TurBoss_at_cnc: and this the one that break th maschine
10:17 AM TurBoss_at_cnc: http://dpaste.com/3SGKM32
10:18 AM IchGucksLive: M6 T1.0
10:18 AM IchGucksLive: cool a float as tool number
10:19 AM IchGucksLive: TurBoss_at_cnc: realy G21
10:19 AM IchGucksLive: not G20
10:19 AM TurBoss_at_cnc: mm here no?
10:26 AM gregcnc: The first one is code for a cat, the second makes a circular pocket.
10:26 AM IchGucksLive: TurBoss_at_cnc: your cad/cam tolerance is to high
10:26 AM TurBoss_at_cnc: yes
10:27 AM TurBoss_at_cnc: g64=
10:27 AM gregcnc: what's wrong with these files?
10:27 AM TurBoss_at_cnc: ?
10:27 AM IchGucksLive: 0,002 off
10:27 AM TurBoss_at_cnc: I launched the pocked an this error start apearing
10:27 AM TurBoss_at_cnc: on every other file
10:28 AM TurBoss_at_cnc: stable does not have this problem
10:28 AM gregcnc: the g10 error?
10:28 AM TurBoss_at_cnc: yes
10:28 AM gregcnc: it's not a problem with the file
10:28 AM TurBoss_at_cnc: ah
10:28 AM gregcnc: use stable linuxcnc release
10:28 AM TurBoss_at_cnc: ok
10:29 AM TurBoss_at_cnc: I'll repoort on github
10:29 AM gregcnc: i sent you a link to the report for this error
10:29 AM gregcnc: https://github.com/LinuxCNC/linuxcnc/issues/269
10:29 AM TurBoss_at_cnc: will do later now i have to leave
10:29 AM TurBoss_at_cnc: in 5 min
10:30 AM IchGucksLive: all the moves are off 0,002
10:31 AM gregcnc: off to where? or are you saying arc radius and endpoints don't match?
10:31 AM IchGucksLive: yes
10:31 AM IchGucksLive: move to G00 X-0.4540 Y-2.4480
10:31 AM IchGucksLive: G03 X0.4540 Y2.4490 I0.4540 J2.4480 F960.00
10:31 AM gregcnc: that's not the error he's getting
10:31 AM IchGucksLive: 4490
10:32 AM TurBoss_at_cnc: I did the post on the issue
10:32 AM IchGucksLive: TurBoss_at_cnc: is ther a DXF on that
10:33 AM IchGucksLive: i see only holes
10:33 AM TurBoss_at_cnc: djx where?
10:33 AM TurBoss_at_cnc: its a pocket and a cat
10:33 AM TurBoss_at_cnc: dxf
10:34 AM IchGucksLive: ok so it is tordorial milling path
10:34 AM TurBoss_at_cnc: no
10:34 AM TurBoss_at_cnc: or yes
10:34 AM TurBoss_at_cnc: its a pocket to make a hole
10:35 AM IchGucksLive: size off pocket
10:35 AM TurBoss_at_cnc: 11.5
10:35 AM TurBoss_at_cnc: or so
10:35 AM IchGucksLive: or only a test
10:36 AM TurBoss_at_cnc: 2mm
10:38 AM IchGucksLive: TurBoss_at_cnc: you can overcome this problem by telling the post to use 5 digits
10:38 AM IchGucksLive: then you are more up to the precision
10:38 AM TurBoss_at_cnc: ok
10:41 AM TurBoss_at_cnc: I have redone my config in 2.78
10:44 AM IchGucksLive: TurBoss_at_cnc: here is the running G-code https://pastebin.com/qqK7X3EK
10:45 AM gregcnc: why ddi you change it to G20?
10:45 AM IchGucksLive: he said no mm inch
10:46 AM TurBoss_at_cnc: oops
10:46 AM TurBoss_at_cnc: have to leav
10:46 AM TurBoss_at_cnc: e
10:46 AM TurBoss_at_cnc: thanks!
10:47 AM IchGucksLive: gregcnc: works as well as expected also on G21
10:49 AM IchGucksLive: ok im off as well till later
10:52 AM JT-Shop: so TurBoss found a bug in master :)
10:53 AM gregcnc: yeah it was already reported
10:58 AM CaptHindsight: http://www.ebay.com/itm/Lathe-Engine-/222508076146 $3k
10:58 AM CaptHindsight: Weight Of The Unit Is 20,900 Lbs.
10:58 AM gregcnc: tha'ts will turn brake rotors
11:01 AM chopper79: Hello
11:01 AM CaptHindsight: https://www.youtube.com/watch?v=xQB5ltzFeA8 worth it for $3k
11:02 AM chopper79: Jog pendent on 7i92+7i77. Using pin 1,17,18,19 on 7i77 forjog pendent. Normally in HAL I would change the serial to 300xxxxxx, but would this still be the same when using 7i92+7i77 vs 5i25+7i77?
11:03 AM chopper79: 16,17,18,19
11:03 AM gregcnc: ebay one looks clean compared to that one
11:12 AM pcw_home: yes, the sserial mode applies to the daughtercard only
11:14 AM LeelooMinai: I just got the parallels. They are lovely and all, but, again, wrapped in some oily paper-like something. So, I clean them, and WD-40?
11:16 AM LeelooMinai: I presume they put that much oil on them only for storage, right?
11:19 AM archivist: LeelooMinai, keep oiled or in anti rust paper
11:20 AM LeelooMinai: Hmm, even if they will be sitting in my room?
11:20 AM LeelooMinai: archivist: When you say "oiled", what is that oil kind?
11:21 AM archivist: some places are a bit humid and some people have "rusty fingers"
11:21 AM gregcnc: i have those fingers
11:21 AM archivist: any water repellent
11:21 AM LeelooMinai: gregcnc: Are you sure you are not an Alien? :)
11:21 AM LeelooMinai: They had acidic saliva.
11:22 AM LeelooMinai: archivist: So, WD40 would be fine, right?
11:22 AM gregcnc: my birth certificate says human
11:22 AM sync: wd40 is evaporates for the most part
11:22 AM LeelooMinai: Probablyu forgery:p
11:22 AM archivist: should be but that dries, recover a after use or twice a year
11:22 AM sync: use some kind of machine oil
11:22 AM gregcnc: I use boeshield long term or hydraulic oil
11:22 AM roycroft: i just wipe mine with a blue paper towel before and after using them
11:23 AM archivist: there are better products for protection
11:23 AM LeelooMinai: sync: I thought it leaves a film that is pretty good at protecting from rust - I saw some video on YouTube and it looked to work pretty good.
11:23 AM roycroft: the cutting oil i use on the mill keeps them protected just fine
11:24 AM roycroft: i've been using the same set for about 9 years in my unheated shop and there's not the slightest hint of corrosion on them
11:24 AM LeelooMinai: Just a bit caucious about nasty chemicals in my room - not sure if hydraulic oil is safe:)
11:24 AM gregcnc: just sitting there is safe
11:24 AM gregcnc: some stink though
11:24 AM chopper79: pcw_home: That is what I was thinking. Thank you and one more thing. I get an error on start up saying enco0 is not found. Not sure why though. any suggestions?
11:24 AM gregcnc: don't cook on it
11:24 AM LeelooMinai: That's another part - I like WD40 because it smells nice.
11:24 AM sync: LeelooMinai: it is not made for that
11:25 AM archivist: parfum De WD
11:25 AM chopper79: sorry enc0
11:25 AM LeelooMinai: sync: Er, it even has on the can that it preotects from rust...
11:25 AM gregcnc: it's consumer grade at best
11:27 AM roycroft: leeloominia: after you get this you can thank me for telling you to buy it:
11:27 AM roycroft: https://www.mscdirect.com/product/details/56450521
11:27 AM LeelooMinai: Hmm, I see North Korea did an impressive ballistic missile launch - so, I guess they are not kidding.
11:27 AM chopper79: pcw_home: I should say that enc0.count is not found
11:27 AM roycroft: it will pay for itself the first time you need to make multiples of the same part
11:27 AM sync: LeelooMinai: that is just marketing wank
11:28 AM LeelooMinai: sync: The missile launch or wd40? :)
11:28 AM sync: it was made to displace water after nuclear rocketmotor casings were cleaned to protect them for a short term
11:29 AM LeelooMinai: sync: I saw a video where they tested some methods of rust prevention and WD-40 was pretty impressive (by some guy, not commercial or anything) - I mean, ok, maybe it was not designed for that, but it does not mean it cannot have some extra features...
11:29 AM Jymmm: LeelooMinai: FAIL http://www.cnbc.com/2017/04/28/north-korea-test-fires-ballistic-missile-report.html
11:29 AM LeelooMinai: roycroft: Er, what is that...
11:29 AM roycroft: it's a work stop
11:29 AM chopper79: I have hm2_7i92.0.7i77.0.0.enc0.count in one of my HAL files. (The one with all my mpg stuff in it) This was no issue on my 5i25+7i77 setup,
11:30 AM roycroft: you clamp it on the fixed jaw of your milling vise
11:30 AM roycroft: you index the first part
11:30 AM roycroft: and then you can swap parts at will and they will automatically be indexed
11:30 AM LeelooMinai: roycroft: But cannot you just use the side of the jaw for that?
11:31 AM LeelooMinai: Jymmm: That's an old one...
11:31 AM roycroft: that is a little fiddly
11:31 AM Jymmm: LeelooMinai: ah
11:31 AM roycroft: it's a lot easier to have a hard stop than to have to line osmething up each time
11:31 AM LeelooMinai: Jymmm: http://www.cnn.com/2017/05/15/europe/north-korea-putin-russia-missile/index.html
11:31 AM pcw_home: chopper79: maybe typo, maybe wrong firmware in 7i92 etc
11:31 AM pcw_home: maybe 7I77 5V or Field power missing
11:32 AM LeelooMinai: roycroft: Right, ok, makes sense.
11:32 AM roycroft: even for a hobbyist it makes sense
11:32 AM roycroft: if you have 12 parts to drill and tap, that's 60 or more operations
11:33 AM chopper79: pcw_home: the field ground needs a common gound with mpg supply correct?
11:33 AM pcw_home: Yes
11:33 AM roycroft: spending 30 seconds or more aligning each part for each operation can add a half hour or more to the job
11:33 AM chopper79: ok... that might be it as I do not have one
11:34 AM roycroft: there are fancy mill stops. but the $10 one works brilliantly for the majority of mill work on small parts
11:35 AM LeelooMinai: roycroft: I guess I could make something like that myself from aluminum now, at least in theory:)
11:35 AM roycroft: you could
11:35 AM roycroft: although steel would be better
11:36 AM LeelooMinai: Right, steel... Can steel be milled on a CNC made mostly from aluminum even?
11:37 AM LeelooMinai: Or it will end horribly?
11:37 AM roycroft: very light cuts
11:37 AM roycroft: it won't ever be time-efficient
11:38 AM LeelooMinai: Sure, though for me that is not a problem.
11:38 AM roycroft: but you should be able to make reasonable parts out of steel, on a very small scale
11:38 AM LeelooMinai: Hmm, I guess would be nice to be able to micro-machine some steel parts - must try one day.
11:38 AM roycroft: and making a mill vise work stop like that doesn't require much machining
11:39 AM LeelooMinai: Though I don't even have means to cut steel stock right now - I can only cut aluminum because I have alu-cutting carbidde tipped blade, but it has "for non-ferrous metals" on it.
11:39 AM roycroft: your machine will be a lot better at plunge cuts in steel than shearing cuts
11:40 AM gregcnc: bigger problem is high RPM
11:40 AM roycroft: yes
11:40 AM roycroft: although again, with reall light cuts one can use small tooling
11:40 AM LeelooMinai: The frame is not 100% alu to be fair - I have used 3 steel angles in strategic places.
11:40 AM gregcnc: not if spindle runout is .001-.002"
11:41 AM roycroft: that work stop is a tiny part
11:41 AM LeelooMinai: And I have substantial torque on the stepper - 400-something oz/inch I believe
11:41 AM roycroft: if you're talking about boring an engine block on your machine, even with light cuts, i'd say that's right out
11:42 AM roycroft: but tiny parts might be ok
11:42 AM LeelooMinai: Right, that was my plan - make a car engine on it:)
11:42 AM roycroft: what's your slowest spindle rpm?
11:42 AM LeelooMinai: 100 rpm
11:42 AM roycroft: oh, that's fine for small end mills on steel
11:42 AM LeelooMinai: But, I don't know how to measure the torque profile on a spindlw.
11:42 AM gregcnc: what have you cut at 100RPM?
11:42 AM * TurBoss is back
11:42 AM roycroft: yes, is there any torque at 100rpm?
11:42 AM LeelooMinai: gregcnc: My finger mostly:)
11:43 AM roycroft: i think that the only way to answer your question is for you to mount a hunk of steel in the vise and try to machine it
11:43 AM gregcnc: She wants the answer before it succeeds/fails
11:43 AM roycroft: just don't try to hog off 0.050" of steel in one pass
11:44 AM roycroft: start with 0.005"
11:44 AM LeelooMinai: roycroft: No idea - my OCD pushes me into finding a way of measuring it with some method over a range of speeds.
11:44 AM TurBoss: JT-Shop :Hello, found this one ---> http://i.imgur.com/5k5vU0f.png
11:44 AM TurBoss: :-)
11:44 AM roycroft: gregcnc: the answer is "maybe" :)
11:44 AM gregcnc: been there done that
11:46 AM LeelooMinai: TurBoss: http://linuxcnc.org/docs/html/gcode.html <- G10 requires those parameters - is meaningless by itself.
11:46 AM gregcnc: oh my
11:46 AM TurBoss: but I don't manually issue G10
11:46 AM gregcnc: leeloo check the log from this morning
11:46 AM LeelooMinai: gregcnc: About what?
11:46 AM gregcnc: his errors
11:47 AM TurBoss: i'm on pre 2.8
11:48 AM LeelooMinai: TurBoss: Are you the one who had stepper tunning backwards? :)
11:48 AM TurBoss: hmmm no?
11:49 AM LeelooMinai: gregcnc: Did not read anything instersting...
11:50 AM LeelooMinai: TurBoss: So where does this g-code come from
11:50 AM gregcnc: that error had nothing to do with G10
11:50 AM TurBoss: when clicking on "regular offset" button
11:50 AM gregcnc: and "regular offset" is a very bad translation of touch off
11:50 AM archivist: that is not that buttons name in english
11:50 AM LeelooMinai: A, so it's a bug or something?
11:51 AM TurBoss: seems yes
11:51 AM gregcnc: that was the conclusion
11:51 AM TurBoss: but I have touch off too
11:51 AM gregcnc: that's tool touch off
11:51 AM TurBoss: ah
11:51 AM TurBoss: ok
11:51 AM roycroft: excellent
11:51 AM roycroft: my indicator holder has shipped
11:51 AM roycroft: i'll probably get it wednesday or thursday
11:52 AM LeelooMinai: But the message is prtetty specific... Spells the reason and line number - so what is on that line 1 even in the code?
11:52 AM gregcnc: reads the logs and come back with your conclusion
11:53 AM LeelooMinai: Maybe I need to go back further, because could not find anything.
11:53 AM LeelooMinai: Today's morning?
11:54 AM LeelooMinai: Did he have the same nick? :/
11:54 AM JT-Shop: TurBoss: I'm out of bandwith and can't look at any images
11:55 AM chopper79: Ok... I common grounded field ground and mpg ground. Still enc0 does not exist. My config is set to =300xxxxxx and I have also tried =300xxx and enc0 still will not show up. When I add show pin *7i77* in my hal file enc0 does not show up in the list. The error does show that mode3 is an option in my firmeware also. Any pointers?
11:55 AM gregcnc: https://github.com/LinuxCNC/linuxcnc/issues/269
11:55 AM LeelooMinai: No he didn't, changed it to TurBoss_at_cnc at some point - that's why.
11:57 AM roycroft: you watch too much welder pr0n, jt-shop
11:59 AM LeelooMinai: gregcnc: I see, ok - never had it happen, but I do not home on startup.
12:00 PM pcw_home: chopper79: do all the field inputs and outputs show up?
12:00 PM LeelooMinai: BTW, who are the linuxcnc core developers? Are they here even, or they "work in the shadows"?
12:00 PM JT-Shop: roycroft: dunno what happened
12:00 PM chopper79: pcw_home: yes they all show up and the mill works great. So I was just wanting to add my mpg and can not get enc0 to show up
12:01 PM pcw_home: what version of linuxcnc, I think the MPG names changed at some point
12:01 PM chopper79: 2.8 pre
12:03 PM chopper79: wonder if they changed to encoder.0.counts and not enc0.counts?
12:06 PM pcw_home: No, I think enc0 is right, heres what i get with master (and a 7I76E)
12:06 PM pcw_home: hm2_7i76e.0.7i76.0.0.enc0.count
12:08 PM chopper79: ok.. I have hm2_[HOSTMOT2] (BOARD).0.7i77.0.0.enc0.count
12:12 PM chopper79: Anything special I can do to see if I am in Mode 3?
12:13 PM pcw_home: can you post your hal and ini files somewhere? If I had to guess, the mode is simply not set (so you are in mode 0)
12:14 PM chopper79: Sure give me a few to get them on pastebin
12:19 PM chopper79: pcw_home: sent you an dropbox link for my personal box.
12:22 PM chopper79: in DM
12:23 PM Crom: Started on wiring my Alarm from my steppers to my estop circuit
12:24 PM LeelooMinai: Alarm from steppers?
12:24 PM LeelooMinai: Some driver signal?
12:25 PM Crom: I have iHSS57-36-2 jmc-motor.com integrated closed loop steeps
12:25 PM Crom: Steppers
12:26 PM Crom: Morning IchGucksLive
12:26 PM IchGucksLive: good evening from germany
12:26 PM IchGucksLive: Crom: why alarm from stepeprs are they closed loop
12:27 PM pcw_home: chopper79: your ini file has the config with the sserial option but your hal file doesn't reference the config string
12:27 PM Crom: I have iHSS57-36-2 jmc-motor.com integrated closed loop steeps
12:27 PM chopper79: oh
12:27 PM Crom: Steppers
12:28 PM IchGucksLive: ok
12:28 PM LeelooMinai: Crom: Hmm, interesting - hwat is the idea there? Are they for some special applications?
12:28 PM Crom: I got tired of loosing steps
12:29 PM IchGucksLive: Crom: more force then 2Nm gives you at 72 V a real good systme
12:29 PM Crom: using them on my 3040
12:29 PM pcw_home: in other words you hal file has
12:29 PM pcw_home: loadrt [HOSTMOT2](DRIVER)
12:29 PM pcw_home: but should have
12:29 PM IchGucksLive: i will never use servos
12:29 PM pcw_home: loadrt [HOSTMOT2](DRIVER) config=[HOSTMOT2](CONFIG)
12:29 PM LeelooMinai: I attacched an encoder on my X axis to see if I lose any, but did not seem so, so now I don't know if I can gain anything from having encoders on all the axis.
12:30 PM Crom: i had gutless 42oz motors
12:30 PM IchGucksLive: 425
12:30 PM LeelooMinai: Mine are over 400, maybe that's why they are solid.
12:30 PM chopper79: pcw_home: Let me give it a try
12:30 PM IchGucksLive: Crom: realy 42
12:31 PM Crom: the 283ozin from my integrated steppers are fine...
12:31 PM IchGucksLive: you can have on 20usd 425
12:31 PM IchGucksLive: and with DM556 48V
12:31 PM IchGucksLive: if wirers exeed 10m 30feet
12:32 PM IchGucksLive: i use 880M
12:32 PM IchGucksLive: and 72V
12:32 PM LeelooMinai: I already ordered two more encoders, so I will probably make brackets for them and use them, but mostly for the OCD satisfying factor:)
12:32 PM IchGucksLive: moving 500kg
12:32 PM IchGucksLive: or 1080lbs
12:33 PM Crom: $114 for integrated closed loop steppers... I like... driver is matchedto motor, encoder on board and a micro controller for the PID loops...
12:33 PM LeelooMinai: I have those drivers too, but at 32V only right now I think.
12:33 PM IchGucksLive: ok as you can aford it go for it
12:34 PM IchGucksLive: LeelooMinai: if you go 48 you can encrese almost to 4th the speed you are unsing
12:34 PM Crom: i've wasted more than $114 in time on the bad steppers
12:34 PM LeelooMinai: Crom: Sounds good, but, the minus is that if something goes boom, it will be harder to work around it.
12:34 PM IchGucksLive: LeelooMinai: on Leadshine 880m and 72V below 10feet wire you can reatch 20m/min
12:35 PM IchGucksLive: at 0,01mm precice
12:35 PM chopper79: pcw_home: Well that allowed LCNC to launch. Jog does not work.... Time to look inot that issue now. Thank you
12:35 PM LeelooMinai: That's why I tend to prefer "generic" components more or less, exception being Mesa cards, since, well, they are awsome and there's not much that can replace them.
12:35 PM Crom: when i'm able i'll get another motor for the 4th axis and it'll be backup for the other axis..
12:36 PM IchGucksLive: Crom: 4th axisis gearing to be spend most
12:36 PM LeelooMinai: IchGucksLive: Lol, at that speed my CNC stand would probably topple over:)
12:36 PM IchGucksLive: high precision 30:1 or even 90:1
12:37 PM IchGucksLive: LeelooMinai: one depends on the other
12:37 PM LeelooMinai: I need to make this stand grate again definitelly.
12:37 PM LeelooMinai: great*
12:37 PM IchGucksLive: sl TR
12:38 PM IchGucksLive: ask
12:38 PM roycroft: are you going to make a hat that says "make stands great again"?
12:38 PM roycroft: because you need the hat first
12:38 PM roycroft: otherwise nobody will know what you're doing
12:38 PM Crom: already havea 4th
12:38 PM LeelooMinai: Not much into hats:)
12:38 PM IchGucksLive: gregcnc: still on
12:39 PM Crom: kidlette got sunburned eyelids... doh...
12:40 PM LeelooMinai: But I have already plans to make the sides of the stand useful - like making shelves there for collets, endmills, fixing blocks, etc. and having a polycarbonate door on there.
12:41 PM LeelooMinai: Can custom make the holes for everything with CNC, etc.
12:42 PM LeelooMinai: Then I will maybe get the hat.
12:42 PM LeelooMinai: Is anyone here using linuxcnc with some kind of touch-screen?
12:44 PM IchGucksLive: there is touchy as a front end
12:44 PM IchGucksLive: test it in sim
12:45 PM IchGucksLive: LeelooMinai: most lathe users are using this
12:45 PM LeelooMinai: Right, I saw that part, but wondering about the hardware - can a tablet be used instead of a monitor? For some reason touch-screen monitors have silly prices.
12:46 PM IchGucksLive: no
12:47 PM LeelooMinai: That's lame... Some tablets have hdmi inputs,m so they could just send the mouse coordinates/touch info back.
12:47 PM IchGucksLive: LeelooMinai: there are 12V touch screens for connecting
12:47 PM LeelooMinai: And you can buy them cheap and in any size.
12:47 PM IchGucksLive: to standard plugs
12:47 PM IchGucksLive: size is a problem
12:48 PM LeelooMinai: I guess one could make make an app for Android that talks back to linuxcnc through USB or something else...
12:49 PM IchGucksLive: LeelooMinai: i use this one on plasmas
12:49 PM IchGucksLive: http://www.pollin.de/shop/dt/NTMwOTc4OTk-/Bauelemente_Bauteile/Aktive_Bauelemente/Displays/7_17_78_cm_Display_Set_mit_Touchscreen_LS_7T_HDMI_DVI_VGA_CVBS.html
12:50 PM LeelooMinai: IchGucksLive: Right, this + nice microscope would probably work:)
12:50 PM IchGucksLive: it is not for construction
12:50 PM IchGucksLive: only to use a a control display
12:50 PM LeelooMinai: I know, but still - tiny for a GUI.
12:50 PM IchGucksLive: and therfor it is ok
12:51 PM LeelooMinai: If you want to see the OpenGL part especially.
12:51 PM IchGucksLive: look at the sim touchy
12:51 PM IchGucksLive: the buttons are that huge
12:52 PM LeelooMinai: Maybe two monitors - one small for controls and one to display things that do not need touching would be an idea too.
12:52 PM LeelooMinai: Not sure if that can be done with linuxcnc right now, but probably?
12:52 PM IchGucksLive: what do you think you need more then touch off and positionig
12:53 PM IchGucksLive: start /stop
12:53 PM IchGucksLive: ok im automated
12:53 PM LeelooMinai: Small touch screen + nice joystick + montor for the rest imo would be nicest.
12:53 PM IchGucksLive: it loads since more then 4 years the only file
12:54 PM IchGucksLive: as from master CAM it outputs onla N700.iso
12:54 PM IchGucksLive: to the mashine folder
12:54 PM IchGucksLive: no filebrowser at all
12:55 PM IchGucksLive: plasmas normaly only got one tool
12:55 PM IchGucksLive: and of cause the XHC-hb04 does the maion thing
12:56 PM IchGucksLive: main
12:56 PM LeelooMinai: IchGucksLive: Tons of things... No limits really: any time you add some nice hardware to the machine, you will probably want to display some info. Like you have for the spindle, encoders, stops, etc. I treat my "CNC mill" more like a "CNC platform" - need it to be flexible since this is for hobby, experiments, etc.
12:56 PM IchGucksLive: agree but then you will not have a 7"
12:56 PM IchGucksLive: 50" for dismlaying live cam
12:57 PM IchGucksLive: on a 3040
12:57 PM LeelooMinai: No, 7" I guess would be find for the touchy parts providing you have another big monitor for displaying.
12:57 PM LeelooMinai: fine*
12:57 PM IchGucksLive: hi Goodlord
12:57 PM IchGucksLive: how are your gcode things going
12:58 PM IchGucksLive: LeelooMinai: are you around asian ground
12:59 PM LeelooMinai: No idea what that means:)
12:59 PM IchGucksLive: nick name gessing
12:59 PM LeelooMinai: You mean background?
12:59 PM IchGucksLive: no are you in Asia
12:59 PM LeelooMinai: No, Canada
01:00 PM LeelooMinai: Wait...
01:00 PM LeelooMinai: A, no, ok, checked - yes, Canada
01:00 PM IchGucksLive: what part the french or the neg
01:00 PM IchGucksLive: ENG
01:00 PM LeelooMinai: Ontario - no french talk here, thankfully
01:01 PM IchGucksLive: im on the french boarder of Germany
01:01 PM LeelooMinai: Germany has border with France?
01:01 PM IchGucksLive: you need more education
01:02 PM LeelooMinai: Ok, checked, indeed seems to have - not long, but still:)
01:03 PM IchGucksLive: not long ? its the longest of all
01:03 PM LeelooMinai: IchGucksLive: Borders change, you know - since I was young some countries even changed and morphed into two, like Chechoslovakia...
01:03 PM IchGucksLive: agree
01:04 PM IchGucksLive: they changed into 4
01:04 PM LeelooMinai: And on the east side, all those small Russian countries popped up.
01:04 PM IchGucksLive: popped also out of RUS
01:04 PM LeelooMinai: Lost track by now.
01:04 PM IchGucksLive: leave it that way
01:04 PM IchGucksLive: how is the weather there
01:05 PM IchGucksLive: we are hedding into summer till thursday
01:05 PM IchGucksLive: on friday it may be autom like
01:05 PM LeelooMinai: I guess where I live (100km from Toronto,) weather is probably not tham much diffrerent than in Germany - a bit longer and colder winter, yes, but it's not Syberia here by any means.
01:06 PM gregcnc: mostly G0 and G1 here with M7 tonight
01:06 PM IchGucksLive: ive been more then 5 times at Toronto and niagra falls
01:06 PM roycroft: it's going to be in the mid to upper 20s here starting on this week, and going through next week
01:06 PM roycroft: a bit of rain tonight and tomorrow through mid-day, then we get a nice sunny warm spell
01:07 PM roycroft: average high is 19 this time of year
01:07 PM roycroft: and it's been in the mid teens for the past few days
01:07 PM IchGucksLive: gregcnc: did turboss fixe it
01:07 PM gregcnc: dunno i was on break
01:08 PM IchGucksLive: ok break is the best workphase
01:08 PM IchGucksLive: time
01:08 PM LeelooMinai: Bad thing is, if there's WWIII and surely places like New York and Toronto will go first, I will have pretty bad time probably.
01:08 PM roycroft: tomorrow is when i'm mounting my lathe on its stand, and that would be very difficult if i'm unable to move some machinery out onto my driveway, so the sunny breaks are arriving just in time
01:09 PM IchGucksLive: LeelooMinai: i live some miles away from the biggest US base outside the states
01:09 PM roycroft: trump tower in new york will be one of the first places hit in wwiii
01:09 PM gregcnc: what tdo they keep at the tower?
01:09 PM IchGucksLive: roycroft: from friendly firer
01:09 PM LeelooMinai: roycroft: Unless there's a Russian silo hidden inside:p
01:09 PM roycroft: but if north korea every get their icbm system working, the northwest coast of the us will definitely be a target
01:09 PM LeelooMinai: roycroft: Did not see the news? They just did.
01:10 PM roycroft: so they say
01:10 PM roycroft: kim jong un is about as believable as donald trump
01:10 PM IchGucksLive: only hidden facts
01:10 PM LeelooMinai: No, it is confirmed - I mean they have videos of the launch and it went far up close to Japanese coast (Japanese must be pretty mad right now probably)
01:11 PM LeelooMinai: Semms one bis US military base is also in range there, so a lot of people will not be happy now.
01:12 PM roycroft: japan is far far away from north america
01:12 PM IchGucksLive: the sun will go up tommorow even withot us
01:12 PM LeelooMinai: Well, baby steps:)
01:13 PM IchGucksLive: so im out of this Gn8 from germany
01:13 PM IchGucksLive: have a nonbit breaking day
01:18 PM Loetmichel: i doubt kim will ever get to the point that he can reach the us. way before that there will be an "accident" in their fission bomb plant that cleans the whole country from the map... wanna bet?
01:21 PM LeelooMinai: Loetmichel: Well, look athat range on the map there - it's far worse than I thought
01:25 PM LeelooMinai: (http://www.cnn.com/2017/05/15/europe/north-korea-putin-russia-missile/index.html)
01:26 PM LeelooMinai: Now Japan instead of making nice CNC machining parts will have to put more $$$ into military:/
01:26 PM SpeedEvil: Aren't nuclear ICBMs just very rapid large scale CNC?
01:27 PM LeelooMinai: I guess they can mill Earth a bit, but that's more like that metal erosion technique:)
01:28 PM LeelooMinai: O, I finally found the scalpel blade at lost month ago - under my bed.
01:29 PM LeelooMinai: Glad I found it this way.
01:31 PM LeelooMinai: Ok, so I am makin CAM steps - does anyone here model the actual vise? I saw some guy on YouTube doing that in Fusion 360, but not sure if that's normal practice or him just being over-the-top.
01:31 PM gregcnc: it can be useful
01:33 PM LeelooMinai: Right, but requires a bit of extra work. Like having the model of the vise... Though I suspect that the one I have is cloned from something like Kurt - looks pretty similar. Unless they all copy from something...
01:33 PM LeelooMinai: Also, can linuxcnc import "stock" for the display?
01:34 PM LeelooMinai: Say at least something that looks like a block.
01:36 PM LeelooMinai: Would be nice if one could specify at least simple line coordinates and colors in some file and then they could be turned on/off - to model places on the CNC that are important to see.
01:37 PM gregcnc: that is usually done in cam
01:38 PM LeelooMinai: Yes, but when you run the job, this is the plasce where you want it to be verified really.
01:39 PM LeelooMinai: Say, if linuxcnc was aware of some cubical areas that are "no - go" zones, that would already allow a lot.
01:39 PM gregcnc: you can setup probing routines to measure the stock
01:40 PM LeelooMinai: Yes, sure, but you cannot tell linuxcnc that there's a vise there and it's not a good idea to move into it, even when doing jogging by hand.
01:40 PM gregcnc: that's why there is an operator present
01:41 PM LeelooMinai: But operators make mistakes...
01:41 PM gregcnc: and get fired
01:41 PM LeelooMinai: You see - just because of the software shortoming - bad.
01:41 PM gregcnc: typ in wrong cooridantes of nogo zone and still operator error
01:42 PM LeelooMinai: Hmm, next step would be scanning the table with a laser to map all the fixtures, etc.
01:42 PM gregcnc: we are still a way away from self aware machines
01:42 PM LeelooMinai: gregcnc: Ok, but I am not talking sci-fi here, but useful and not that complicated features:)
01:43 PM gregcnc: then i expect the dev version to have have coded update tonight
01:43 PM LeelooMinai: Of course the tool bit has to be taken into account, but that's already done anyways - the tool table is taken into account from what I have seen on the display,
01:43 PM gregcnc: thing is someone has to program, and that isn't trivial amking stuff up takes seconds
01:44 PM LeelooMinai: gregcnc: I know, I am a programmer, just cannot stop those ideas coming to my mind when I interact with software.
01:45 PM gregcnc: trust me these aren't new ideas
01:45 PM LeelooMinai: Hmm, you see... And what? There was no interest in them?
01:46 PM gregcnc: drop what you're doing and code them
01:47 PM LeelooMinai: gregcnc: I could, but I took CNC/electronics as a hobby to take a break from decades of programing, so... not a good idea.
01:47 PM gregcnc: a well this may be the exact reason it doesn't exist
01:48 PM LeelooMinai: Well, too bad I guess - as I wrote once, all the work seems to go into 3D printer software:/
01:50 PM roycroft: attempting to solve social problems with technology is almost always a fail
01:50 PM roycroft: and putting a dog fence around your part so you don't damage your vise is a social problem in my view
01:51 PM gregcnc: some machine controls do support this
01:51 PM LeelooMinai: I don't see how it's a social problem - humans make errors and there's a lot of safety built into mavhines, This is just one form of it.
01:53 PM sync: LeelooMinai: that is a solved problem
01:54 PM sync: you can load any arbitrary geometry in your cad software and tell the cam not to go there
01:54 PM LeelooMinai: Also, a great sanity check - when you load g-code and see the toolpath you can quickly veryfy visually that CAM did not spit out anything deadly.
01:54 PM renesis: 22:11:22 < LeelooMinai> You see - just because of the software shortoming - bad.
01:54 PM renesis: thats not software shortcoming, thats operator shortcomings
01:54 PM gregcnc: people who don't want human error eliminate the human. robot to load unload, machine runs itself night and day
01:54 PM LeelooMinai: sync: Sure, but when you move g-code from CAM into the actual CNC, things change.
01:54 PM sync: no
01:55 PM renesis: ?
01:55 PM LeelooMinai: Yes, they do:)
01:55 PM gregcnc: why would they change?
01:55 PM renesis: fixture awareness should be done in CAM
01:55 PM gregcnc: my model of my mill and fixtures is exactly what's in the machine
01:55 PM sync: if your machine is configured differently than your simulation in cam, that is entirely your fault
01:55 PM renesis: what youre describing is some sort of automated machine that isnt a cnc machine
01:55 PM LeelooMinai: Because you are dealing with different environments and there can ber discrepancies.
01:55 PM renesis: nope
01:55 PM renesis: you were lazy at cam
01:55 PM gregcnc: it was a bit of "extra" modeling time, but the benefit is worth it
01:56 PM renesis: and didnt have an aware enough operator to deal with it
01:56 PM renesis: there are solutions to these things, making the controller more complicated and less reliable doesnt seem like a great one
01:56 PM sync: it is not the operators fault, imo
01:56 PM renesis: it depends on the situation
01:57 PM sync: sure, but most of them are just button pushers
01:57 PM LeelooMinai: renesis: That's nice to say on IRC when pretending the real world is ideal, but in practice, no... Like one example I had was Fusion 360 putting tool retracts in some places, and it assuming that Z0 is at the top of axis, and this cannot be configured it seems right now.
01:57 PM gregcnc: I suppose the process should be such that a button pusher can't break it
01:57 PM sync: they are not qualified to see the issues
01:57 PM renesis: if the operator is a setup machinist and its his job to make the code from CAM work, its maybe his fault
01:57 PM LeelooMinai: renesis: Or it can be a bug in the CAm, and 100 other things.
01:57 PM sync: LeelooMinai: that is due to how machine WCS work
01:58 PM renesis: which is CAM/operator error
01:58 PM LeelooMinai: sync: Imo that is due to the export to linuxcnc being inflexible.
01:58 PM sync: if you decided that you want to have your MCS differently, your problem
01:58 PM renesis: export to linux cnc is rs274?
01:58 PM sync: well, just change your z axis origin
01:58 PM LeelooMinai: sync: I don't think there's a rule for where your Z axis 0 has to be.
01:59 PM renesis: there isnt, but there are conventions
01:59 PM LeelooMinai: If there is, it's only a "thumb" rule probably.
01:59 PM gregcnc: you can't chenge teh tool change position in f360?
01:59 PM renesis: and what does it matter, you should be using workspace coordinates
01:59 PM sync: actually there is a rule
01:59 PM renesis: on a lathe for machine coordinates?
01:59 PM LeelooMinai: renesis: Yes, so as you see, it's CAm being inflexible imo, and already you have a potential for error/confusion. And this was just an example.
01:59 PM renesis: isnt on a mill
02:00 PM renesis: leeloominai: if you want to reinvent cnc thats fine
02:00 PM renesis: dont call it cnc
02:00 PM sync: iso 841 defines it to be the top iirc
02:00 PM renesis: and dont try and ruin cnc machine controllers with it
02:00 PM renesis: sync: Z up?
02:00 PM LeelooMinai: Saying that CAM and mill running g-code are identical scenarios is naive imo in real world, especially with generic software like linuxcnc and some CAM, that's all I am saying.
02:01 PM sync: well Z up being on top of the travel
02:01 PM renesis: i do machine space so my g53 coordinates are all in negative space
02:01 PM sync: as Z+ is "up"
02:01 PM renesis: oh like directions?
02:01 PM renesis: yeah
02:01 PM renesis: Z is spindle axis, X is long perpendicular axis, Y is other axis
02:02 PM renesis: i dunno if machine space origin is spec'd in that standard, but you dont have to follow the spec you can stick original anywhere in the controller
02:02 PM renesis: same with axis orientation
02:02 PM LeelooMinai: renesis: What do you mean "reinvent" CNC - I am not reinventing anything, just researching if an idea I had is bad, or it's not implemented for other reasons, etc.
02:02 PM renesis: axis output wont make sense
02:02 PM sync: renesis: it is defined in iso 841, as I said ;)
02:03 PM renesis: you were saying about direction!
02:03 PM renesis: but right i dont remember if origin is spec'd
02:03 PM renesis: i might do it the way i do it because from spec and i thought it made sense
02:04 PM LeelooMinai: renesis: Also, if everyone just kept religiously to old ways and never considered anything new, you would not have CNC nowadays, but lots of people with stone tools probably:p
02:04 PM sync: iirc origin is spec'd at the left and towards you most corner
02:04 PM sync: so that all the travel in XY is positive
02:04 PM renesis: right i dont do that
02:05 PM renesis: my g53 is all negative and i try and do workspace originals so all work is positive so i can just look at coordinates and know if its machine or workspace
02:05 PM renesis: *workspace origins
02:05 PM sync: I do, but I usually offset my origin to the middle of the travel so that I don't get strange coordinates when the vise is on the machine
02:05 PM LeelooMinai: Right, and I was supposed to face facing this first part, and doing the usual - 100 thoughts per minute and yak shaving and talking too much on IRC. Same old, same old:/
02:05 PM dioz: how do i make my teamates better with practice?
02:06 PM LeelooMinai: dioz: Gradually replace them with robots imo:)
02:06 PM roycroft: you shave your yak?
02:06 PM roycroft: that must be rather time-consuming
02:06 PM LeelooMinai: I have the Master degree in Yak Shaving and Bike Shedding, yes.
02:07 PM roycroft: i know you're not in nepal, but your part of canada does get rather cold in the winter
02:07 PM dioz: my parents never taught me the importance of education
02:07 PM roycroft: do you dress your clean-shaven yaks in sweaters then?
02:08 PM dioz: yak fur sweaters
02:08 PM LeelooMinai: That is, you can tell me to make something simple, and I can take 5 years to do that, in the process building 20 semi-related things, and research 1000 unrelated:)
02:08 PM dioz: jack of all trades. master of none
02:09 PM LeelooMinai: dioz: Well, that's not really fair - I master a lot, but usually it's temporal, and jump to something else, sometimes coming back, etc.
02:10 PM dioz: uou hand sharpen your own twist drill bits?
02:11 PM gregcnc: leeloo look into changing the post if changing the machine coordinates is not an option
02:11 PM LeelooMinai: E, you don't get it - in this case you would design a drill bit sharpener for a yar and then sharper one buit and move to another thing:)
02:11 PM LeelooMinai: one bit*
02:12 PM LeelooMinai: gregcnc: Yes, I did, but, if y ou change the file and they update the code, you will get desynchronized.
02:12 PM dioz: but if you can't do it by hand how would you design an aparatus to do it?
02:12 PM gregcnc: the post should not be changing on you
02:13 PM LeelooMinai: dioz: By McGyvering, using/abusing some parts you have at hand, sometimes investing in some tools that are affordable, and sometimes making them, then discovering that you also need to make some other tools to make those tools, etc. - that's what "Yak Shaving" is:)
02:13 PM gregcnc: fusion crashed a few machines when an update flipped the Zaxis and people didn't catch it posting
02:14 PM dioz: soubds like a make work project
02:14 PM LeelooMinai: Right, but, the file is under Autodesk control I assume - not sure if they will ever upgrade it or not, etc.
02:15 PM gregcnc: it is not, you can edit the post all you want it is local
02:15 PM LeelooMinai: There's only "use G28" option, and I looked into it, but it seemed risky - again linuxcnc idea of what is going on could be different than the CAM.
02:15 PM gregcnc: so build your machine according to the rest of the world?
02:15 PM LeelooMinai: gregcnc: I know, but I mean if there are improvements to it, etc. then you have to merge your changes back if you want to keep current.
02:15 PM dioz: i mean... mcgyver did, always on the first try, manage to make thibgs work... but things don't usually work first time. ask the mythbusters
02:16 PM gregcnc: your machine nor your post should be chaging that often
02:16 PM LeelooMinai: dioz: I did not say everything works first time - though often it does, especially if you OCD over it for a long time.
02:16 PM dioz: seems easier that re-inventing the wheel every time.
02:16 PM dioz: than
02:17 PM gregcnc: for safety sake
02:17 PM LeelooMinai: gregcnc: You make it sound like they can not add any features to it - there's a lot they can add, if people request it. Like even that Z-axis assumption for example.
02:18 PM LeelooMinai: There's a dialog box where you can set some options right now - maybe 20 of them or so.
02:18 PM gregcnc: you expect a lot for free
02:19 PM LeelooMinai: gregcnc: It's not really free - I mean it's free if you do not make money from it (I thinkup to $100k per year,) but otherwise people pay for it.
02:19 PM gregcnc: fusion is not the first to use free to develop software then charge for it, that time is coming
02:19 PM LeelooMinai: I don't think that would be in their interest.
02:19 PM gregcnc: what percentage of usful work is being made by paid licenses of F360?
02:20 PM * cpresser has f360 at work. paid.
02:20 PM LeelooMinai: gregcnc: How am I to know - I do not work at Autodesk:)
02:20 PM dioz: hopefully they fork and still remain non-free in some way
02:20 PM gregcnc: as the only software available?
02:20 PM cpresser: we use it daily for mechanical designs, mockups, ..
02:20 PM cpresser: yes, as the only 3D CAD/CAM package
02:21 PM LeelooMinai: But the contribution Fusion 360 is making to startupts/hobbyist is huge imo.
02:22 PM LeelooMinai: It trumples pretty much anything that is open source and free right now, so people can actually do interesting things without wanting to hang themselves.
02:23 PM cpresser: I would prefer another non cloud-based software. but fusion is cheap.
02:24 PM LeelooMinai: Right, to be honest it doesn't make any difference to me that it is "online", but there's the "go offline" mode, so, that's even less difference I guess.
02:24 PM LeelooMinai: I thinmk they even removed restriction on how long you can be "offline" some time ago (?)
02:25 PM chopper79: Is there anything that would shut inputs 20-32 off on a 7i77?
02:25 PM LeelooMinai: chopper79: You mean you want to do it, or something di it?
02:26 PM chopper79: Well in halmeter I can not get input 20-32 to go true. I have 5v to the wire and I can read 5v on the 7i77 pysical pin but the inout will not go true....
02:26 PM chopper79: nevermind...needs 24v
02:27 PM Goodlord: i think cnc in this form has a limited lifespan
02:27 PM chopper79: 5v is to low for the inouts
02:27 PM Goodlord: this will become much more dumb public user friendly
02:27 PM LeelooMinai: Hmm, I used 5V inputs on 7i76.
02:28 PM LeelooMinai: Probably depends on whethere you use field power or some other voltage, etc.
02:28 PM chopper79: My field is 24v and forgot that the inputs on the 7i77 will not read below 10v
02:28 PM cpresser: the problem with cloud based stuff is that you dont 'own' the computation. if autodesk decides to change $stuff there is nothing I can do about it.
02:29 PM LeelooMinai: cpresser: Well, you can use an old version offline I guess?
02:30 PM cpresser: LeelooMinai: for a few days/weeks.
02:30 PM LeelooMinai: But then you won't get updates, and if your year licence runs out, you will need to hack something:)
02:30 PM cpresser: LeelooMinai: and all the files are stored in cloud
02:30 PM cpresser: exporting them is possible, but PITA
02:30 PM LeelooMinai: cpresser: Er, no? If they were only stored online, how could you even work offline:)
02:30 PM cpresser: the UI stores stuff in the cloud by default
02:30 PM cpresser: LeelooMinai: cache
02:31 PM LeelooMinai: cpresser: Right, there's a local part and they made it "non blackbox" I think, so you can work offline fine.
02:31 PM LeelooMinai: I forgot the details, but I remember I read one article where they were describing that they make offline mode less painful to people, since many complained.
02:32 PM cpresser: stallman on the topic: https://www.wired.com/2013/09/why-free-software-is-more-important-now-than-ever-before/
02:32 PM cpresser: if autodesk would offer a 'local' cloud, I would totally be fine with that
02:32 PM LeelooMinai: cpresser: https://www.autodesk.com/products/fusion-360/blog/fusion-forecast-offline-mode/
02:32 PM cpresser: I buy the software, setup up my local cloud. thats perfectly fine
02:33 PM LeelooMinai: They plan some extra features even for late this year.
02:33 PM LeelooMinai: Give more control over cache, viewing, etc., so they are not super-cagey about it.
02:34 PM cpresser: those are some nice improvements
02:34 PM cpresser: but still, the data is not on my machine. if they deceide to revoke my licence, delete my designs, share them with $competitor.. there is nothing I can do about it
02:35 PM cpresser: "data not on my machine" as in "I can't controll on which machines my data is"
02:35 PM LeelooMinai: Well, if it's in cache, and you can already select how long it should sit there, it is on your machine...
02:37 PM chopper79: 7i77 in mode 3 can inputs 18 and 19 still take 24v in when using inputs 16 and 17 for jog wheel?
02:37 PM LeelooMinai: Yes, but, there are pluses and minuses to everything - sure, if Autodesk explodes and is gone one day, it will be problematic, but until then, you get fast updates, collaboration features, etc.
02:39 PM LeelooMinai: The problem is that open-source people are unable to even remotely match an application like Fusion in terms of usability - so, what can one do...
02:39 PM cpresser: its unlikely that in the near future that autodesk is going evil; thats why we use it. it does the job and is cheap.
02:40 PM cpresser: open source just takes more time :) think of kicad. imho its better than eagle by now. not on altium level yet. but its on its way
02:40 PM LeelooMinai: Let "linux people" do anything that involves GUI and you are into some horror-ridden result imo:)
02:40 PM * cpresser does not need a GUI^^
02:41 PM LeelooMinai: cpresser: CAN/CAM without GUI is not very usable:p
02:41 PM LeelooMinai: CAD/CAM
02:49 PM chopper79: so close o this mpg. I can get x axis to move (kind of) I have the jog on the mpg set to .01" and X axis will jerk .01" and then go back to zero. This only happens in the + direction and no movement in the - direction.
03:03 PM skunkworks: sounds like you don't have both A/B hooked up..
03:03 PM skunkworks: if you only have 1 - it will count up and back down 1 count
03:04 PM chopper79: skunkworks: That is what it is doing. I will double check connections
03:07 PM chopper79: skunkworks: between A and gnd I get up to 2.5v and between B and gnd I get the same.
03:07 PM chopper79: 5v in
03:08 PM skunkworks: and both a and b are hooked to the mesa card?
03:08 PM skunkworks: is this single ended I assume?
03:08 PM skunkworks: (ttl)
03:10 PM chopper79: A and B are both connected to 7i77 on pins 16 and 17. This is a single ended fanuc wheel.
03:10 PM skunkworks: do you have the jumper correct for single ended? (I assume there are jumpers on the 7i77..)
03:10 PM chopper79: + movement is an increase of .01 everytime and - movement is a increase of .01 every once and a blue moon
03:12 PM skunkworks: 16 and 17?
03:12 PM chopper79: 7i77 in mode 3. no jumpers used
03:12 PM chopper79: yes
03:12 PM chopper79: 16 and 17
03:13 PM skunkworks: isn't 17 and 17 /idx (index) and QA (A channel)
03:14 PM skunkworks: * isn't 16 /idx (index) and 17 QA (A channel)
03:15 PM chopper79: Mode 3 in 7i77 turns field inouts 16,17,18,19 in an mpg input with a 2.5v threshold for 100ppr encoders.
03:15 PM skunkworks: ah
03:16 PM chopper79: So A = 16, B = 17 and suppling the wheel with 5v.
03:16 PM skunkworks: If your measuring 2.5 then it may be too close to the threshold to switch.. Maybe some 1k pullups?
03:17 PM chopper79: I will drop one on real quick
03:21 PM skunkworks: (drop 2 in)
03:21 PM chopper79: no change with 1k pullups
03:24 PM chopper79: Using 2k pullups the axis will move one direction not consistent. Only for one .01 incriment, nothing other way, but it does stay put and doe snot moveback by itself
03:29 PM pcw_mesa: chopper79: check the high and low voltage levels of A and B
03:30 PM Crom: turned my ball screw... That chineseum is hard for stainless!
03:30 PM gregcnc: stainless ball screws?
03:31 PM Crom: stain resistant I think
03:31 PM pcw_mesa: chopper79: low should be close to 0V, high should be close to 5V (measured with voltmeter ground lead on TB2 pin 8)
03:32 PM pcw_mesa: TB2 pin 8
03:34 PM Crom: ALMOST got away with out repacking... but I did... oops I have to shorten the ball screw by a bit.. 1.5 to 2mm
03:34 PM gregcnc: did you make a mandrel to slip the screw on to?
03:34 PM gregcnc: bah nut
03:35 PM Crom: I had a piece of AL windchime the was almost the perfect size... almost... I ended up repacking
03:36 PM chopper79: pcw_home: low is .01v and high is .5v
03:36 PM chopper79: not so high
03:37 PM Crom: I'm going to have a VERY tall Z... but it'll be better when I rebuild the gantry taller
03:37 PM XXCoder: 1 km tall? ;)
03:38 PM LeelooMinai: Do matric people have some name for 1/100th of mm?
03:38 PM chopper79: pcw_home: bad ground
03:38 PM LeelooMinai: metric*
03:39 PM Crom: it used to have 55mm of travel, now it will have about 180mm
03:41 PM XXCoder: you can make something thats pretty tall
03:41 PM XXCoder: for a router
03:42 PM Crom: if I rebuild the gantry to have 250mm clearance under it, I'll be set. My spindle er11 right now I have 90mm stickout from the spindle body
03:44 PM XXCoder: one thing I want to do is extend gantry another 2 or 3 inches or so
03:44 PM XXCoder: not a whole lot
03:47 PM LeelooMinai: XXCoder: I don't think aluminum can take that much deformation.
03:47 PM XXCoder: lol
03:48 PM LeelooMinai: Hmm, I have about 150mm Z travel - figured should be enough for mosty milling.
03:48 PM LeelooMinai: nost*
03:48 PM DaViruz: LeelooMinai: usually just hundreths tenths thousandths etc
03:49 PM Crom: for that, you can just hacksaw the gantry plates, get some angle AL -- thick stuff and extend the side plates with that. you clamp 2 piece of angle together , front piece will be what you bolt to the gantry pieces, the back piece is to align the gantry pieces. and do the same on the front of the gantry pieces
03:49 PM Crom: lemme inkscape something up real quick
03:49 PM XXCoder: I would simply make new sides
03:49 PM XXCoder: make it lean back and little bit taller also
03:50 PM XXCoder: recover some of Y
03:50 PM Crom: I was going to... then the spindle crapped out...
03:50 PM XXCoder: still waiting for bushes?
03:50 PM Crom: I actually want the Y to extend off the front... then I can do dove tails in long boards
03:51 PM Crom: got them... broke one putting it in...
03:51 PM XXCoder: oh yeah
03:51 PM Crom: waiting for money to buy the next set
03:52 PM Crom: wednesday is next payday for me... 1st and 17th...
03:52 PM LeelooMinai: DaViruz: I was asking since in imperial you have "mil" and it's easy to say and the units are good for most parameters, but, in metric micron is too small, so 10 microns would be nicer - I thought that maybe people say something like "5 centis" (for 1/100 of mm) and that would mean 50 microns.
03:53 PM XXCoder: there is deci and centi but former isnt common and latter dont seem usually used for metric machining though could be wrong
03:54 PM LeelooMinai: 10 microns is 2/5 mil - about right there. Maybe I should make up my own name for it: say, one Dude = 10μm
03:55 PM gregcnc: and break this system too?
03:55 PM LeelooMinai: Well, since I am doing everything alone, who cares that I look at the indicator and say to myself "I am off two dudes":)
03:55 PM XXCoder: lol
03:56 PM chopper79: pcw_home: Can I still send 24v to inputs 18 and 19 when in mode 3? I really need those inputs for things and can not afford to lose them.
03:57 PM LeelooMinai: Ok, but something more sane, since imperial people use "tens" to mean fraction of a mil, maybe "tens" for metric could mean microns * 10, so that could work too, say 20 tens would be 0.2mm
03:58 PM LeelooMinai: Never heared metric machinist talk on youtube .
03:59 PM gregcnc: https://www.unc.edu/~rowlett/units/prefixes.html
04:00 PM XXCoder: q0 dm lol
04:00 PM XXCoder: *10
04:00 PM XXCoder: 10 dmm
04:00 PM gregcnc: not tens, but tenths
04:00 PM LeelooMinai: Right, I know all the prefixes, obviously, being from metric country:)
04:01 PM gregcnc: are you trolling now, isn't canada in the us?
04:01 PM XXCoder: and metric :P and no.
04:01 PM Crom: hmmm but there is no good .1mm and .01mm nicknames
04:01 PM LeelooMinai: cm is very popular unit, and it's 10mm, but, did not really see anythong for 10μ
04:02 PM Crom: .1mm dim .01 hum ?
04:02 PM LeelooMinai: I guess cμm, but that's not nice to say...
04:02 PM Crom: heh...
04:03 PM gregcnc: i think um but hey maybe that's not good enough and we should change it
04:03 PM LeelooMinai: gregcnc: It's 25 smaller than mill - a bit akward, don't yuou think?
04:04 PM LeelooMinai: gregcnc: Also, do you really think that Canada is in US? :p
04:04 PM gregcnc: i don't use mil because it's vague
04:04 PM gregcnc: didn't we conquer canada?
04:04 PM LeelooMinai: And I am in Canada, but was born in Poland = metric system.
04:04 PM LeelooMinai: Maybe in South Park...
04:05 PM gregcnc: born in USA learned only inch, and design and work in mm, microns even
04:05 PM gregcnc: at least the kid are learning metric, but they are telling them a cm is ~1/2"
04:06 PM LeelooMinai: gregcnc: Kids learning where?
04:06 PM gregcnc: my kids at school
04:06 PM LeelooMinai: I know, but in US? I thought that's not happening.
04:06 PM gregcnc: it is
04:07 PM Crom: I have cousins in Canadia
04:07 PM XXCoder: its progressing VERY slowly
04:07 PM XXCoder: but it is happening
04:07 PM LeelooMinai: gregcnc: Well, I am not there, but from youtube, I would never guess so.
04:08 PM LeelooMinai: Maybe it's a new generation, since FFP games are in metric or something:)
04:08 PM gregcnc: but this CORE crap sucks, kids in 3rd grade can barely multiply
04:08 PM Crom: STEM added something...
04:08 PM CaptHindsight: http://www.ebay.com/itm/Sim-Metal-Engine-Lathe-Skinner-Chuck-/232305384742 decent lathe for $1800 or best
04:09 PM LeelooMinai: But you have now great secretary of education, so, things will get better:p
04:09 PM Crom: Buffalo skin robe $1195 + shipping..
04:09 PM CaptHindsight: with fur?
04:09 PM gregcnc: I understand what CORE is attempting to teach, but kids will need 20 years of schooling at this rate to finish 12th grade
04:10 PM Crom: http://www.braintan.com/buffalo/
04:10 PM CaptHindsight: Crom why would a buffalo need a robe?
04:11 PM CaptHindsight: that silly
04:11 PM XXCoder: gregcnc: its supposely better way, basically build structure then later stuff is easier and faster
04:11 PM XXCoder: what I hate is test test homework homework
04:11 PM Deejay: gn8
04:11 PM XXCoder: way too much testing that they essentally teach jkids how to pass tests and not actual concepts
04:12 PM XXCoder: and yes there is essentally "Big Test" - companies that contract and require THEM grade tests and disallow teachers to fix grades if grade was wrong
04:12 PM CaptHindsight: gregcnc: public schools here are the absurdly dummbed down
04:12 PM Crom: CaptHindsight: you getting the Buffalo's Robe... They don't need it anymore... It's steak and ribs now in some resturant
04:12 PM gregcnc: but basic math isn't a concept it should be memorized
04:13 PM XXCoder: it is a concept
04:13 PM XXCoder: understand concept rest of it is very easy
04:13 PM gregcnc: you have kids in school?
04:14 PM XXCoder: I dont have kids but my bro does
04:14 PM Crom: that's what CORE is.. ROTE memorization of things on tests...
04:14 PM XXCoder: and I live withj my bro
04:14 PM CaptHindsight: gregcnc: my daughter wasted several hours a day in public junior high and then took college classes at night
04:15 PM gregcnc: well I was thinking about sending my kids somewhere over the summer
04:15 PM LeelooMinai: CaptHindsight: From what I saw public schooling does not get much love there, no?
04:16 PM Crom: I took the California High School proficiency test and basically CLEP'd out of high school.. I was class of 83, but graduated in '81
04:16 PM CaptHindsight: public schools here should just be called indoctrination and social engineering cluster fucks
04:16 PM LeelooMinai: I mean all I read was that they cut fundings for it and move it to provate schools, etc.
04:16 PM CaptHindsight: kids need time off to learn
04:16 PM XXCoder: vocher system ugh usa
04:17 PM CaptHindsight: it's a lost cause here for several decades
04:18 PM CaptHindsight: it keeps the masses dumb and well trained
04:18 PM LeelooMinai: So the next generations will be even worse.
04:19 PM Goodlord: lol
04:20 PM Goodlord: mass formal compulsory education was always about indoctrination
04:20 PM XXCoder: no.
04:21 PM XXCoder: its about not having dumb public
04:21 PM CaptHindsight: John Gotto did a pretty good job of explaining the history behind the US system
04:22 PM Goodlord: what were the other two, barnes and gintis?
04:22 PM CaptHindsight: Goodlord: but most people in the USA don't see it that way
04:22 PM * LeelooMinai removes "it that way"
04:22 PM CaptHindsight: and not just Trump supporters
04:23 PM CaptHindsight: it's also a topic you're not suppose to discuss, like religion
04:23 PM CaptHindsight: consume and conform
04:24 PM roycroft: if you say "most people in the usa" then, by definition, it's "not just trump supporters", since the majority are opposed to him
04:24 PM gregcnc: it's a topic people don't understand, few paren'ts really consider there to be any other way to learn
04:24 PM XXCoder: I didn't say anything about trump?
04:25 PM CaptHindsight: roycroft: just clarifying
04:26 PM CaptHindsight: shop just hit 80F
04:26 PM CaptHindsight: time to get an AC
04:26 PM gregcnc: crazy warm here today
04:26 PM roycroft: we're going to have a heat wave starting wednesday
04:26 PM gregcnc: compared to recent weks
04:26 PM CaptHindsight: and back to low 60's in a couple day
04:27 PM roycroft: temps in the mid to upper 20s
04:27 PM roycroft: when 19 is the average high this time of year
04:27 PM CaptHindsight: roycroft: C or F?
04:27 PM roycroft: c
04:27 PM XXCoder: I'm reasonable sure that will become common
04:27 PM roycroft: i don't use silly temperature units
04:27 PM gregcnc: roycroft conform to the american °F
04:27 PM CaptHindsight: uhmerica
04:28 PM roycroft: fahrenheit was german
04:28 PM XXCoder: and imperial system british heh
04:28 PM roycroft: we don't use imperal units
04:28 PM roycroft: imperial
04:29 PM XXCoder: not anymore
04:29 PM roycroft: we use american customary units
04:29 PM CaptHindsight: Celsius was Swedish
04:29 PM roycroft: we haven't used imperial units in a century and a half
04:29 PM XXCoder: well its based on previous
04:29 PM LeelooMinai: potato tomato imo: }
04:29 PM DaViruz: most of them just happens to be the same :P
04:29 PM XXCoder: indeed
04:29 PM CaptHindsight: was Kelvin Scottish?
04:30 PM Goodlord: Trump is ok, hes saying stuff at least, i would go much much further though
04:30 PM DaViruz: you're just hiding the fact thay you use the units handed down to you by your british overlords ;)
04:30 PM roycroft: lord kevin was scots-irish
04:30 PM XXCoder: yep
04:30 PM LeelooMinai: Goodlord: ...
04:30 PM roycroft: born in belfast, educated in glasgow
04:30 PM CaptHindsight: yup https://en.wikipedia.org/wiki/William_Thomson,_1st_Baron_Kelvin
04:30 PM XXCoder: so race segeration, slavery, killing off disabled people like myself?
04:31 PM CaptHindsight: https://www.thesun.co.uk/video/tv/jeremy-clarkson-has-a-backhanded-compliment-for-scotland-on-the-grand-tour/
04:31 PM LeelooMinai: Goodlord: I thought that by this time people realized that he is mentaly unfit for anything. Not yet?
04:32 PM XXCoder: lee starting to. his approval rating took a dive, and before firing of corey too
04:32 PM CaptHindsight: bbl
04:32 PM Goodlord: Lee - im in england anyway so none of my business really lol
04:33 PM XXCoder: sad to see someone think that "some people is better than others" based on race
04:33 PM LeelooMinai: I mean how long can it take people and what one has to do:) I mean by now I feel like all most outrageous and absurd things that could be done was done by him, and what... nothing?
04:34 PM XXCoder: LeelooMinai: trump has something even worse
04:34 PM XXCoder: he think that since he is rich he is quite literally better on everything
04:34 PM Goodlord: what? old Trump a racist? no way
04:34 PM XXCoder: otherwise he'd not be rich
04:35 PM XXCoder: gospel of propserity is really crazy.
04:36 PM LeelooMinai: XXCoder: BUt that's seems to how things work in US overall - it self-propells so that rich people get more influence, adjust everything so it keeps going even further, and so on, so on.
04:36 PM XXCoder: sadly yes
04:37 PM LeelooMinai: I only wonder how it all will crash/end and if I will survive that long to satisfy my curiosity:)
04:37 PM roycroft: oh my god
04:37 PM roycroft: i just heard something horrible
04:37 PM roycroft: in the uk
04:37 PM roycroft: in some hospitals
04:38 PM roycroft: medical personnel are resorting to using pen and paper to write things down
04:38 PM XXCoder: LeelooMinai: hes starting to get backlashes lets see whats happening.
04:38 PM gregcnc: they must be fairly old because young people can only point ot the icons
04:38 PM LeelooMinai: Sounds absurd and very dramatic:)
04:38 PM XXCoder: well time to go to work. later
04:41 PM LeelooMinai: lol, I went to read something about Fusion on youtube thinking "I need to stop thinking about what Trump does", and the first thing I read was "Trump Wants Right-Wing Radio Host To Be Chief USDA Scientist"
04:42 PM roycroft: i've disengaged quite a bit since the election
04:42 PM roycroft: it's the only way i can keep my sanity
04:43 PM roycroft: but it's still important to be outraged every time trump does something outrageous
04:43 PM LeelooMinai: Well, good luck - he is everywhere.
04:43 PM roycroft: we cannot let his crap be come the norm
04:44 PM roycroft: i cancelled satellite tv
04:44 PM roycroft: which was really nice
04:44 PM roycroft: because now i don't have to hear people yelling at each other every time i turn the tv on
04:44 PM Tom_L: becoming a hermit?
04:44 PM roycroft: no
04:44 PM roycroft: not at all
04:44 PM roycroft: just disengaging from most of the beltline political crap
04:45 PM roycroft: ota tv is very nice
04:45 PM roycroft: that plus netflix
04:45 PM roycroft: i watch a lot of cinema anyway
04:45 PM Tom_L: you can still pick the channels you watch
04:45 PM roycroft: i always have
04:45 PM LeelooMinai: Right, I have no TV for more than a decade now - but before I had it only for Eurosport and Discovery Channel - would watch them when training for marathons (on a stationary bike).
04:45 PM roycroft: the yelling people were on most of them
04:45 PM roycroft: although #1 yeller has just been fired
04:46 PM LeelooMinai: The O'Raily guy?
04:46 PM roycroft: but his ratings had dropped
04:46 PM roycroft: yes
04:46 PM roycroft: that's what people aren't saying about that incident
04:46 PM roycroft: he was losing to lawrence o'donnell in ratings
04:46 PM roycroft: so he got fired
04:47 PM roycroft: ironically, o'donnell may lose his job in a month, even though he's taken over ratings in his timeslot, and is now #2 overall (behind rachel maddow) in cable news shows
04:47 PM roycroft: news/commentary
04:47 PM roycroft: i really don't miss that stuffff
04:47 PM roycroft: i thought i would
04:47 PM roycroft: but i don't
04:47 PM LeelooMinai: It's kind of unwatchable for a sane person.
04:47 PM roycroft: and i'm getting more stuff done
04:48 PM roycroft: today after work i'm going to lift my lathe a wee bit, slip a board with a piece of paper underneath each end, and trace around the base
04:49 PM roycroft: so i can make some gaskets for when i install it
04:49 PM roycroft: i'd rather keep oil from dripping down into the inside of the stand
04:49 PM roycroft: i'll do that instead of turning on the tv and listening to people yell at each other
04:50 PM roycroft: see, this works brilliantly
04:51 PM LeelooMinai: roycroft: Wait until you reach for the oil bottle and on the label there is "Trumoil - the bestest oil"
04:51 PM LeelooMinai: Trumpoil:)
04:51 PM roycroft: it will be terrific!
04:51 PM roycroft: and i can't believe nobody invented it earlier
04:53 PM dioz: i have to ssh into a box so i can ssh into another box for access to the admin lan
04:53 PM LeelooMinai: Hmm, I have two flute 6mm HSS endmill and some 6mm carbide "hog" one... I guess the hog one is not really useful for facing stuff?
04:53 PM roycroft: it's useful for hogging
04:53 PM dioz: i want a lathe
04:53 PM roycroft: does carbide tooling work well on aluminium?
04:53 PM LeelooMinai: Well, it has flat end, but 4 flutes.
04:54 PM roycroft: 2 flutes are better for aluminium
04:54 PM LeelooMinai: I know it works great at breaking small mills in aluminum - that's all my experience so far:)
04:54 PM LeelooMinai: Right, I know, for chip evacuation apparently. Ok, I guess I will just use "normal" HSS one.
04:54 PM gregcnc: carbide certainly works in aluminium
04:55 PM sync: roycroft: yes, it works very well
04:55 PM roycroft: yes, for chip evacuation
04:55 PM roycroft: you have those big, soft, gummy chips that you need to get rid of
04:55 PM sync: ZrO2/PCD coated carbide gives you excellent results
04:55 PM dioz: do guys build mdf or lvl frames for 3 axis gantry rigs?
04:55 PM gregcnc: light machines with fast spindle like few flutes
04:55 PM roycroft: i work mostly i steel
04:56 PM roycroft: in
04:56 PM roycroft: now that i have a nice, bigger lathe i might start making shiny brass things though
04:56 PM roycroft: because shiny is good
04:56 PM LeelooMinai: I lkke those facing bits that you insert small carbide pieces and screw them and then face large area, but probably ER11 system is too tiny for them to work well, so they don't even make them.
04:57 PM sync: I found some nice highly positive inserts for my lathe tooling
04:57 PM sync: now I just always run my lathe flat out
04:58 PM dioz: drive it like you stole it
04:58 PM roycroft: i have a buttload of hss tooling blanks
04:58 PM gregcnc: sync which inserts?
04:58 PM roycroft: so i'll probably be turning with hss for quite a while
04:59 PM dioz: i want to make a table from pallet wood
04:59 PM dioz: hahahahaha jk
04:59 PM sync: gregcnc: kennametal ccgt09t304hp kc730 grade
04:59 PM Cromaglious_: I've seen some nice oak tables made out of pallet wood
04:59 PM dioz: laminated and stacked with a nice varnash?
04:59 PM roycroft: a lot of asian pallets are made out of semi-exotic hardwoods
05:00 PM roycroft: usually poor quality, but the boards can be big enough that you can cut out the knots and stuff and still have some usable boards
05:00 PM dioz: what are the things that are wood that are elipse in shape and you use them to connecr pieces of wood....
05:00 PM dioz: longitudinaly
05:00 PM roycroft: biscuits
05:00 PM LeelooMinai: With a biscuit joiner.
05:01 PM roycroft: biscuits are nice, but not very strong
05:01 PM sync: dioz: always.
05:01 PM roycroft: floating tenons are stronger
05:01 PM roycroft: handcut dovetails even stronger ;)
05:01 PM LeelooMinai: Or easy mode - I use Kreig "jig" thing a lot.
05:01 PM dioz: yah lots of jigs out there i seen
05:01 PM dioz: jig and a router
05:01 PM sync: festool domino :)
05:02 PM roycroft: i use biscuits quite a bit when gluing up boards to make a wide board
05:02 PM roycroft: but i use them primarily for positioning
05:02 PM roycroft: and rely on the glue joint for strength
05:02 PM dioz: you guys ever go pick up pallet wood? we got a place around here that's stacked like fuck. just a mountain
05:02 PM dioz: "free firewood" it says
05:02 PM roycroft: even norm "power tools are i" abrams admits that biscuits are not really the bees knees
05:02 PM sync: haha
05:03 PM sync: that is because it is annoying to dispose of
05:03 PM sync: because it is treated wood
05:03 PM dioz: i've always wanted to take some and do the stacked laminate table tops
05:03 PM dioz: i think they look decent
05:03 PM roycroft: asian pallet wood is generally not treated
05:03 PM roycroft: treating it costs money
05:03 PM roycroft: it's just nailed together green
05:03 PM roycroft: and once the product that's strapped to it leaves shore it doesn't matter if the pallet rots
05:04 PM sync: it does, if that happens too often the ports here will refuse the containers
05:04 PM gregcnc: you can't even bring untreated pallets into the country?
05:04 PM sync: you can make your own, sure, but shipping them in is difficult
05:04 PM dioz: i'm kind of big on re-using and repurposing... i'm not a horder though... how do i convince my wife that i need 150 pallets in the back yard for a couple days while i break then down?
05:05 PM dioz: ditch the wife?
05:05 PM dioz: we got a dude in the neighbourhood that is a professional hoarder
05:05 PM dioz: he has stuff he'll never usel
05:06 PM dioz: everything has a purpose though
05:06 PM roycroft: you'd be doing well to stack a dozen on a pickup at a time
05:06 PM roycroft: don't bring in 150 in a day
05:06 PM roycroft: bring in a dozen, break them down, then get another dozen
05:06 PM dioz: then you need a metal detector and spend time denailing. then you need a board plainer
05:07 PM dioz: then you need clamps for laminating and some kind of biscuit type assembly
05:07 PM dioz: yada yada
05:07 PM roycroft: you can make clamps
05:07 PM roycroft: you can use a hand plane for both surfacing and jointing
05:07 PM roycroft: and if you joint accurately you don't need biscuits
05:08 PM roycroft: all that other stuff is not necessary
05:08 PM roycroft: it can just make the job go faster
05:08 PM dioz: not stronger would you say?
05:08 PM roycroft: no
05:08 PM roycroft: biscuits do not make edge joints stronger if the edges are jointed properly
05:08 PM roycroft: they just help align the boards while the glue is setting
05:09 PM roycroft: with a good glued edge joint, the wood will fail before the glue joint fails
05:09 PM roycroft: unless you're using glue that's designed to give, like hide glue
05:09 PM LeelooMinai: Maybe if the biscuits are made from steel, they will make it stronger:)
05:09 PM dioz: how you clamp?
05:09 PM roycroft: if you anticipate ever having to repair the project, hide glue is good
05:10 PM roycroft: which is why veneer is still attached with hide glue to this day
05:10 PM roycroft: i use this style for most things:
05:10 PM roycroft: https://www.amazon.com/Bessey-KR3-550-50-Inch-Parallel-2-Pack/dp/B001HSO6TU/ref=sr_1_8?s=hi&ie=UTF8&qid=1494884411&sr=1-8&keywords=bessey+clamps
05:10 PM roycroft: but those are expensive, and i don't have enough of them for really big projects
05:11 PM roycroft: in which case i still have a bunch of pipe clamps
05:11 PM dioz: i was thinking of a way to do it with ready rod
05:11 PM roycroft: i use bar clamps and spring clamps and sometimes cam clamps when applying edging and things like that
05:11 PM dioz: and a few holes with a couple plates
05:12 PM LeelooMinai: I have cheap pipe clamps too: https://www.flickr.com/photos/100017731@N03/18619188984/in/dateposted-public/
05:12 PM roycroft: i have some couplers that let me join bessey clamps end to end so that i can clamp really long pieces
05:12 PM LeelooMinai: I designed this table saw stand in Fusion 360 btw, when I first tried it:)
05:12 PM roycroft: keep in mind, folks, that i've been buying/collecting tools for 40 years
05:12 PM dioz: bosch or milwaukee?
05:13 PM roycroft: i've had time to acquire some nice stuff
05:13 PM roycroft: is that a generic question, dioz?
05:13 PM roycroft: i have no overall power tool religious affiliation
05:13 PM dioz: pick your side buddy
05:13 PM dioz: fence rider
05:14 PM roycroft: for battery tools, i used to be heavily invested in dewalt 18v stuff
05:14 PM roycroft: back in the nicad days
05:14 PM dioz: are you cummin or strokin buddy?
05:14 PM dioz: ford!
05:14 PM roycroft: my very first battey tool was a makita 7.2v 3/8" drill
05:14 PM roycroft: i still have it
05:14 PM roycroft: from the mid '80s
05:14 PM roycroft: and i still have the two original batteries for it
05:14 PM roycroft: and they still work
05:14 PM dioz: the legendary 7.3
05:14 PM dioz: non turbo idi
05:14 PM roycroft: i've been moving to milwaukee battery tools over the last few years
05:15 PM LeelooMinai: I once bought this Dewalt table saw on sale, after fighting with some scary old one I found in the basement: https://www.flickr.com/photos/100017731@N03/18739607054/in/dateposted-public/
05:15 PM dioz: make it run on vegetable oil
05:15 PM roycroft: i have 12v and 18v lithium ion milwaukee stuff now
05:15 PM roycroft: for routers i use porter-cable exclusively
05:15 PM roycroft: my worm drive saw is a skilsaw
05:15 PM roycroft: my sds hammer drill is bosch
05:15 PM dioz: roycroft: i started with bosch and have a bunch of bosch lion batteries. can't switch now
05:15 PM LeelooMinai: And I must say, the difference in quality and safety, etc. was hige
05:15 PM roycroft: my corded drills are milwaukee
05:16 PM roycroft: yes, with battery tools it's pretty necessary to stay within one product line
05:16 PM roycroft: the tools cost nothing
05:16 PM dioz: you got the milwaukee jacket?
05:16 PM roycroft: it's the batteries where all the money is
05:16 PM roycroft: i don't wear branded clothing like that
05:16 PM LeelooMinai: Before I got it, everytime I had to cut something big I was feeling as I was playing with my life - it was very stressful:)
05:16 PM dioz: roycroft: heated jackets are nice i live up north
05:17 PM roycroft: i have sweaters :)
05:17 PM dioz: hah
05:17 PM * roycroft lives where it doesn't get too cold
05:17 PM dioz: okay
05:17 PM roycroft: plus
05:17 PM roycroft: remember
05:17 PM roycroft: whisky is like a sweater that you wear on your inside
05:17 PM dioz: we go from +40 celcius to -40 celcius round here
05:17 PM roycroft: so when it gets cold
05:17 PM roycroft: pour yourself a wee dram
05:18 PM dioz: and i need to start putting on gloves aroubd -20 celcius
05:18 PM dioz: or the hands don't open and close like they should. get too cold
05:19 PM dioz: when the screws and material starts sticking to your hands it's cold
05:19 PM dioz: you ever shoot a spiker into frozen 2x4's?
05:20 PM dioz: framing in winter is rouuugh
05:20 PM * roycroft intentionally lives where it doesn't get too cold
05:21 PM dioz: i wanna move
05:21 PM dioz: to the coast
05:21 PM roycroft: the lower mainland is nice
05:21 PM dioz: how low?
05:21 PM dioz: oregan?
05:21 PM roycroft: down to the 49th
05:21 PM roycroft: south of there is now trumpland
05:21 PM roycroft: you don't want to move to trumpland
05:22 PM dioz: oregan has open carry doesn't it?
05:22 PM roycroft: i think so
05:22 PM roycroft: i have zero interest in guns
05:22 PM roycroft: so i don't pay attention
05:22 PM dioz: oh me either tbh. i've shot a shotgun a couple times.
05:23 PM roycroft: i also have zero interest in taking everybody's guns away
05:23 PM dioz: i mighr be able to get into it though
05:23 PM LeelooMinai: For facing with 6mm 2 flute in 6061, what is a sane depth I should aim at?
05:23 PM roycroft: it's part of the zero interest in guns thing
05:24 PM roycroft: that depends on your machine, leeloominai
05:24 PM dioz: roycroft: what about making guns?
05:24 PM roycroft: some of the processes employed in gunmaking are of interest
05:24 PM LeelooMinai: I set CPT to 50 microns, so that's covered, and use 6600 RPM, and the bit has 13mm flute, but, not sure about the depth
05:24 PM roycroft: but since i have no interest in guns, there's no point in my learning those processes by making guns
05:24 PM dioz: roycroft: damn rights
05:24 PM roycroft: it would be like making scrap and tossing it
05:25 PM dioz: :(
05:25 PM dioz: poor scrap
05:25 PM LeelooMinai: Hmm, maybe I should use more than 50 microns
05:25 PM roycroft: try 0.015" to start?
05:25 PM roycroft: see how it goes?
05:25 PM roycroft: you know your machine better than we do
05:25 PM dioz: what is .015 in fractions of an inch?
05:25 PM LeelooMinai: roycroft: Didn't you say you boycott imperial units? :p
05:25 PM dioz: 16th?
05:25 PM LeelooMinai: roycroft: How not very consistent of you...
05:26 PM gregcnc: 15/1000
05:26 PM roycroft: i machine in us customary units, because metric tooling is too damn expensive here
05:26 PM roycroft: i never said "boycott", i don't think
05:26 PM roycroft: i say "avoid" though
05:26 PM LeelooMinai: Right, but, I am specifying parameters for CAM in Fusion, so feeds and speeds, etc.
05:26 PM dioz: so like.. 7 or something
05:27 PM LeelooMinai: But ok 15 mil, where 40 mil is one mm
05:27 PM roycroft: 0.015" is closer to 1/64 inch than 1/16 inch
05:27 PM gregcnc: i'd guess <1mm doc, but hard to say, maybe <0.5mm
05:27 PM LeelooMinai: So I have a sense what it is - a bit less than half a mm
05:28 PM roycroft: i'd go over to your machine and conduct an experiment
05:28 PM LeelooMinai: And considering that I have less then that extra stock, problem solved:)
05:28 PM roycroft: and then go back to fusion and plug in the best result
05:29 PM LeelooMinai: Hmm, right - I wish I had this conversational NativeCNC panel installed - that would be good for tests.
05:29 PM roycroft: 0.5mm is ~0.020"
05:29 PM roycroft: so close to what i suggested
05:29 PM gregcnc: overrides are good for that
05:29 PM roycroft: you can write some g-code by hand to do a test like that
05:29 PM LeelooMinai: Right, but that's more awkward imo.
05:29 PM * roycroft goes home
05:31 PM LeelooMinai: Diesn't seem very complicated:) http://i.imgur.com/FFxxfod.png
05:34 PM LeelooMinai: Hmm...
05:34 PM LeelooMinai: But, shouldn't it enter the stock from the side instead of top like that?
05:34 PM dioz: so anyone tell me how to control my pool stick welding?
05:34 PM dioz: i either blow holes or not enough pool
05:35 PM dioz: piece gets super hot warps
05:35 PM dioz: even on low
05:35 PM LeelooMinai: I saw the big facing things always entering from the side and not plunging, but maybe for normal endmill it's ok? Or I should enter from the side too?
05:35 PM dioz: like 65
05:36 PM dioz: 14gauge mild steel
05:37 PM LeelooMinai: A< no, ok, it enters from the side - I had it going from end to start in simulation for some reason.
05:48 PM Cromaglious_: dioz how big of rod?
05:49 PM Cromaglious_: 1g guage I'd be using TIG
05:49 PM Cromaglious_: 14guage
05:51 PM Cromaglious_: 14guage you want to be tacking it with like 1/4" long tacks... then to finish out welding you'd be welding maybe 1/2" then moving down 3" and doing another 3"
05:51 PM Cromaglious_: 14guage you want to be tacking it with like 1/4" long tacks... then to finish out welding you'd be welding maybe 1/2" then moving down 3" and doing another 1/4" then move another 3"
05:52 PM Cromaglious_: 14guage I wouldn't use over a 1/16" rod and maybe 45amps max
05:52 PM Cromaglious_: if I didn't have TIG I'd gas weld it
06:04 PM dioz: hah
06:04 PM dioz: only stick
06:05 PM dioz: it's requirement
06:06 PM Cromaglious_: hell it's 14guage... put the ground clamp on the back get a 1/4" rod crank is up to 200amp and spot weld it
06:06 PM dioz: yah.
06:06 PM dioz: i never done any weldin though
06:07 PM dioz: must've burned up about 20 or so rods today with a bunch od coupons
06:07 PM dioz: just couldn't feel consistant
06:07 PM Cromaglious_: physics is pretty easy.. get stuff hot to plastic state, and a bit liquid (puddle) and stir...
06:09 PM dioz: i think as the rod burns i'm not closing the gap fast enough so it punches holes.
06:09 PM dioz: then i get too close and the puddle is overwhelming
06:10 PM dioz: i've been trying it with the rod slanting away from me and kind of "pressing" it into the groove
06:10 PM Cromaglious_: on thin stuff you want to use really short welds... cause you can't sink the heat into the material fast enough... strike arc, get puddle, stop... move 3" do same thing...
06:10 PM dioz: yah
06:11 PM Cromaglious_: if you had a big block of copper you could back the weld and get longer welds because you could alot of the heat into the copper
06:12 PM Cromaglious_: s/could alot/ could sink alot/
06:12 PM Cromaglious_: and turn down your amps a bit...
06:13 PM roycroft: on thin stuff you do gtaw :)
06:13 PM Cromaglious_: you want enough to strike and make a puddle, but not enough to make instant puddle and then blow back out
06:13 PM roycroft: or at least gmaw
06:13 PM roycroft: or grab a torch
06:14 PM dioz: oh yah tig for sure
06:15 PM Cromaglious_: I know you can stick weld 14guage sheet metal... I've done it with 1/8" 60xx AC rod and an old miller buzz box a/c arc welder
06:15 PM dioz: i got tons and tons of rod to burn and more than enoigh coupons
06:16 PM dioz: i mean i could probably go for a solid hour
06:16 PM dioz: but right now it's the same two results
06:16 PM dioz: blow through or huge puddle
06:16 PM Cromaglious_: may be 18guage or 20guage with 1/16 rod and DC stick..
06:16 PM dioz: and when i get the edge there's blow throigh.
06:17 PM Cromaglious_: turn down your amps
06:18 PM Cromaglious_: turn it down until you can't get an arc... turn it up until you have arc and can make plastic almost puddle and then turn it up a smidge more
06:18 PM dioz: i think welding benches should be nice and high too
06:18 PM dioz: not fucking crotch level
06:19 PM chopper79: The mpg I was working on is functioning well when the machine is not homed. After I home the machine the mpg no longer functions. I have never had this happen before. Any suggestions?
06:21 PM Cromaglious_: chopper79, weird...
06:21 PM Cromaglious_: fire up halshow and start checking signals and pins on the MPG
06:22 PM Cromaglious_: chopper79, DOH! you need to switch from 'auto' mode to 'jog' or 'manual
06:22 PM Cromaglious_: mode
06:22 PM Cromaglious_: it's a button, not sure which one...
06:23 PM chopper79: Is this something new? I have never had to do that before
06:24 PM JT-Shop: chopper79: the mpg only works in manual mode
06:24 PM Cromaglious_: axis.0.jog-enable is a starting point for search
06:26 PM Cromaglious_: something to look at https://forum.linuxcnc.org/media/kunena/attachments/21717/mpg-2.hal
06:26 PM dioz: jog = inch. auto = complete stroke. what is manual?
06:26 PM dioz: is it french?
06:26 PM Cromaglious_: last 2 lines ... sets mpg-enable 1
06:28 PM JT-Shop: F3 in Axis
06:29 PM dioz: doesn't manual act like auto but if you release the button it goes back to first point?
06:31 PM dioz: usually we press brake jog and sheer auto
06:32 PM dioz: ironworker it depends which action you're performing
06:32 PM chopper79: wonder how axis is not letting the mpg work though after homed. I have had many machines and none of them do this. Only this one. I am thinking tha it is in my mpg config. The only this I could put in to allow lcnc to launch was net x-jog-select joint.0.jog-enable <= hm2_7i92.0.7i77.0.0.input-20. The older configs I have use axis.0 instead of joint.0
06:34 PM JT-Shop: chopper79: are you in manual mode when you try and jog?
06:35 PM chopper79: I have tried using F3 in axis and no change in status.
06:37 PM chopper79: Normally after axis homes the mode it falls in is the one I can jog with the mpg in. I can jog with keyboard arrows just not mpg
06:38 PM chopper79: Still can not help but think it has something to do with naming joint.0.jog-enable instead of using axis.0.jog-enable. lcnc will not launch when I use axis.0.jog-enable though
06:45 PM chopper79: name change
06:46 PM LeelooMinai: Hmm, weird - I stall the stepper I think when homing, but when I jog manually at highest speed I do not.
06:46 PM chopper79: no longer uses axis.0 it is now axis.x and axis.y axis.z
06:54 PM chopper79: Sweet... All my control panel buttons are working also, besies one of them which is because I do not have nay more inputs left on my 7i77. All I need is 1 more!!
06:55 PM chopper79: I did not account for using pins 16 and 17 for the mpg when I planned this out. I was thinking I would have used an encoder inout for the mpg. I have 2 encoder inouts open to use but no more i/o
06:56 PM Cromaglious_: yay...
06:56 PM Cromaglious_: figure out how to use the control pins on a serial port..
06:57 PM Cromaglious_: RI and CTS are to in pins I believe
06:57 PM Cromaglious_: two
06:57 PM Cromaglious_: damn winbloz 10.. brb rebooting
07:45 PM LeelooMinai: Is there anything that can be used to replace ER11 collets and be nicer to swap endmills with center finders, etc. - I am just starting, but I am already tired of it:)
08:16 PM LeelooMinai: Hmm, "show program rapids" does not eem to do anything for me.
08:16 PM LeelooMinai: I have g0s there in the code
08:17 PM LeelooMinai: Seems to interact with alpha-blending
08:22 PM M-comrade: LeelooMinai: http://www.genswiss.com/qcollets.htm
08:22 PM M-comrade: i have never used them, just stumbled upon it a while ago
08:25 PM LeelooMinai: They seem to make a step down from ER11 to 8 though
08:33 PM LeelooMinai: Amazing - I faced one side and nothing exploded. Well, left a bit on the side, but that's probably some CAM/stock something I forgot.
08:37 PM LeelooMinai: https://www.flickr.com/photos/100017731@N03/34524155392/in/dateposted-public/
08:38 PM -!- #linuxcnc mode set to +v by ChanServ
08:38 PM LeelooMinai: There are tool marks, but I cannot feel them with finger, so I guess that's normal.
08:41 PM malcom2073: LeelooMinai: hit it with a scotchbrite pad
08:41 PM malcom2073: the marks go away
08:41 PM malcom2073: You can get scotchbrite wheels that go in a grinder, work really well
08:43 PM LeelooMinai: I used kitchen sponge and it almost took them off.
08:44 PM malcom2073: the green side or the soft side?
08:44 PM roycroft: leeloominai: many consider those end mill marks desirable and attractive, as long as they are nice and even
08:44 PM LeelooMinai: However, I made one side, and there are 5 more... I have a feeling that going every time to CAD/CAM to post one facing operation is not a good idea.
08:44 PM malcom2073: You should have subroutines for facing
08:44 PM LeelooMinai: malcom2073: lol... the sof side is a sponge - I don't think it can remove anything.
08:45 PM malcom2073: Haha yeah, the rough side is the same as a scotchbrite pad
08:45 PM LeelooMinai: Right, now I think again back to that Native CAM thing.
08:45 PM roycroft: but if you don't want them, about 10 seconds with some 240 grit wet-dry sandpaper on a hard backer, with some wd-40 sprayed on the part will get rid of the tooling marks
08:45 PM roycroft: if you want it all shiny that's another story
08:45 PM roycroft: and a fair bit more work
08:45 PM LeelooMinai: 240 seems brutal... I have 600
08:46 PM roycroft: 600 won't get rid of the tooling marks in 10 seconds
08:46 PM LeelooMinai: roycroft: I actually know how to make aluminum shiny:)
08:46 PM roycroft: when using abrasives, start with as coarse as you need
08:46 PM roycroft: and progress to finer and finer grits until you attain your desired finish
08:47 PM roycroft: making sure you always completely remove the previous grit's marks before moving on to the next
08:47 PM LeelooMinai: roycroft: I don't know - they seem miniscule - let me try 600 + wd40 for 10 seconds.
08:47 PM roycroft: this is a hobby
08:47 PM roycroft: and you are experimenting and learning
08:47 PM roycroft: so give it a go
08:47 PM * roycroft can't find his circle cutters :(
08:47 PM roycroft: i'm ready to cut out my gaskets
08:47 PM roycroft: i have straight edge, punchs, knives
08:48 PM roycroft: templates
08:48 PM roycroft: but i need circle cutters
08:48 PM roycroft: and i have two really nice ones
08:48 PM LeelooMinai: Right, I took off all the circles with 600, just tiny lines left.
08:48 PM roycroft: that seem to be wrapped up with a cloak of invisibility
08:48 PM roycroft: brilliant!
08:48 PM roycroft: so they were really minor marks
08:49 PM LeelooMinai: I guess time to research some strategy for facing cubes like that.
08:49 PM roycroft: of course, that is aluminium, and i'm more used to working with steel
08:49 PM LeelooMinai: I mean I watched a video on how to square them, but I mean with g-code etc.
08:49 PM roycroft: so i may have underestimated the power of the 600 grit
08:50 PM LeelooMinai: I guess something like 400 would be ideal.
08:50 PM LeelooMinai: For first pass that is.
08:51 PM LeelooMinai: But, of course, I would rather have some polishing attachement on the cnc:)
08:51 PM LeelooMinai: I guess some kind of pad on a sringy shaft would work in theory...
08:51 PM LeelooMinai: springy
09:02 PM roycroft: huzzah!
09:02 PM roycroft: i found the little circle cutter, and it's big enough for what i need to do
09:22 PM Cromaglious_: I need to cut out a bit of my spindle mount for the ball nut to fit
09:22 PM Cromaglious_: think I'm going to use my smaller forsner bits
09:22 PM Cromaglious_: off to home..
09:31 PM LeelooMinai: So, what do people use to edit g-code? I am playing with Atom + plugins, and it's not bad so far.
09:32 PM seb_kuzm1nsky is now known as seb_kuzminsky
09:33 PM jdh: vim
09:34 PM LeelooMinai: Got it to at least understand different g-code groups: http://i.imgur.com/E3Z8MF8.png
09:35 PM LeelooMinai: So it's semi-readable with highlighting at least.
09:35 PM Cromaglious_: well.. be a longer here at the makerspace
09:38 PM LeelooMinai: Loaded that NativeCNC in my sim PC too and now playing with it - looks nice, but I get some g-code errors, so probably need some more configuration time.
09:41 PM Cromaglious_: I need to get my sim linuxcnc going with NativeCNC
09:42 PM LeelooMinai: nativeCAM I should write
09:44 PM Cromaglious_: everytime I install 3.16.x RTAI kernel, I have problems with LSB carp when installing stuff with dpkg or apt-get
09:53 PM LeelooMinai: Ok, read the readme again, and seems it works: http://i.imgur.com/sJhT4G8.png
09:53 PM LeelooMinai: Found the facing operation even.
09:56 PM LeelooMinai: Hmm, lots of stuff there - will take a while to figure all out, but probably worth it.
10:02 PM roycroft: gaskets are done
10:02 PM roycroft: i'm all ready to mount the lathe tomorrow
10:02 PM * roycroft will be so happy to have his shop back
10:12 PM LeelooMinai: Hmm, that NativeCAM has a "show workpiece" checkbox, but I don't see anything changing in the Linuxcnc view.
10:13 PM LeelooMinai: Wonder how it was supposed to show the worpiece.
10:36 PM LeelooMinai: Hmm, on youtube videos the workpiece shows - maybe it's my being over x11vnc or something.
10:41 PM LeelooMinai: O, found how to do it: https://forum.linuxcnc.org/40-subroutines-and-ngcgui/31659-nativecam-is-features-renamed?start=150
10:42 PM LeelooMinai: The "skip lines with /" was the problem
