01:15 AM miss0r2: 'morning
01:22 AM miss0r2: I have 3.5meters of dovetails to cut today. This is going to be exciting :�
01:53 AM Loetmichel: mornin'
02:09 AM Deejay: moin
02:27 AM miss0r2: bah... 3.5 meters of dovetail, and I'm still not done with the first 400mm
02:28 AM miss0r2: trying to make it act nice. I've never been a fan of dovetail cutters
02:29 AM miss0r2: also, the grind on this chinesium cutter is less perfect than I could've wished for
02:33 AM _unreal_: the dove tail keeps going and going and going :)
02:34 AM miss0r2: :]
02:34 AM miss0r2: sure feels like it
02:34 AM miss0r2: Normally for this type of application, I would have found some dovetailed extrutions that would fit my needs, but I couldn't on such short notice
04:26 AM jthornton: morning
04:33 AM XXCoder: morning
04:40 AM jthornton: you use inkscape?
04:54 AM XXCoder: yeah
04:54 AM XXCoder: love it
04:56 AM jthornton: just installed it
04:56 AM XXCoder: first time or?
04:57 AM jthornton: I think I tried it a long time ago in like ubuntu 6 or 8
04:58 AM XXCoder: man inkscape have advanced a lot since then
04:59 AM XXCoder: first time I tried freecad it was crap lol
04:59 AM XXCoder: it was same for inkscape
04:59 AM XXCoder: except less crap
05:01 AM jthornton: how do you make a border on an object like a circle
05:03 AM XXCoder: ah! look at coloring page. click on bottom left area, see 2 tiny color squares?
05:03 AM XXCoder: new mdi window area should appear
05:03 AM XXCoder: it has 3 tabs, color, border color and border pattern
05:05 AM jthornton: https://imagebin.ca/v/4ZFNnvzhTchJ
05:05 AM jthornton: that's my lower left corne
05:05 AM jthornton: r
05:06 AM jthornton: ah I see now stroke must be defined
05:12 AM miss0r2: gaaah... I even see dovetails when I close my eyes!
05:12 AM miss0r2: 1.2 meters done.. 2.3 meters to go!
05:12 AM miss0r2: If I never see another dovetail again it will be too soon :]
05:14 AM XXCoder: look, a dovetail!
05:14 AM XXCoder: jthornton: ya must exist in order to color. :)
05:15 AM jthornton: I figured out the stroke line width was so small I could not see it
05:16 AM XXCoder: its nice to be able to use no stroke
05:16 AM XXCoder: yo
05:23 AM Tom_L: yo
05:23 AM miss0r2: XXCoder: This is alot of dovetail cutting :) and its slow
05:24 AM XXCoder: fun
05:25 AM XXCoder: i made bunch of small parts. one part needs 4 tiny holes with half inch depth blown clear of chips.
05:25 AM XXCoder: i finished 65 of those.
05:25 AM XXCoder: thats lot of blowing.
05:30 AM miss0r2: lol yeah
05:33 AM XXCoder: tomorrow i look forward to same. yay...
05:35 AM miss0r2: hehe
05:35 AM miss0r2: This dovetail cutter has a poor grind. one flute is sticking out a bit... The sound is driving me nuts!
05:36 AM miss0r2: This is taking entirely too long. I will have to come back in tonight
05:37 AM miss0r2: and I'm trying to figure out a good way to clamp this square profile here...
05:38 AM miss0r2: I need to tilt it 45 degrees. so I was just thinking of clamping it with two v-blocks, but I need to take alot off one side & then I would collide with the v-blocks
05:40 AM miss0r2: Either I come up with a clamping solution, or I have to rethink the part :)
05:41 AM miss0r2: if I put it in a v-block in the bottom of the vise, I will damage the sides clamping it.... AND THE RACKET FROM THE DOVETAIL CUTTING IS MESSING WITH MY CONSENTRATION
05:41 AM XXCoder: how about moving clamps?
05:41 AM miss0r2: :D
05:41 AM XXCoder: have m0 clamo finished end, remove clamps off unfinished
05:42 AM miss0r2: theres an added issue: I am going to leave the factory surface on most of the part, i.e. moving it around is out of the question, once I have started machining
05:46 AM miss0r2: basically small v-grooves on the vice would be nice just about now :)
05:48 AM XXCoder: ya my idea isnt moving part
05:48 AM XXCoder: its lamps shuffling
05:48 AM miss0r2: I have no idea:D
05:49 AM XXCoder: pretty stright forward, have m0 where you clamp finished side then remove clamps blocking unfinished part
05:49 AM XXCoder: though might leave mark where tool cuts overlap
05:49 AM XXCoder: hmm
05:49 AM miss0r2: yeah, we don't want that... :)
05:50 AM miss0r2: This this is alot more about finish than precision
05:50 AM miss0r2: its a camera trolley
05:51 AM miss0r2: hmm. but since I will not be doing any hard machining on it, I think I can get away with some cardboard clamping :D
05:52 AM XXCoder: using cardboard to protect finish eh
05:52 AM miss0r2: well... the corners of the square profile
05:52 AM miss0r2: just to even out the pressure a bit.
05:53 AM miss0r2: I have some realy nice thick cardboard, that alot of my older tools came in
05:53 AM miss0r2: bleh! that cutter makes a horrible racket everytime it engages a new stepover.
05:54 AM XXCoder: lol
05:54 AM miss0r2: if they order more of these, I'll get a proper one
05:54 AM miss0r2: or a bucketfull for that matter
05:54 AM miss0r2: or even better; outsource :D
05:54 AM XXCoder: dont have grind setup?
05:54 AM XXCoder: ya sometimes outprocess is better but not always bleh
05:55 AM miss0r2: hehe. I do have a grinder, but I do not have an indexer for it
05:55 AM miss0r2: so, I don't grind tools
05:55 AM miss0r2: well.. it has 2-4-6-8 indexing. but this is a 10 flute cutter
05:55 AM XXCoder: yeah dont seem possible lol
05:55 AM XXCoder: 0 havw primes of 2 and 5
05:56 AM miss0r2: :]
05:56 AM miss0r2: And I don't much feel like making a huge setup taking all day to mount my indexing head on the grinder ect...
05:56 AM miss0r2: I just hope it lasts
05:57 AM XXCoder: yeah
05:57 AM miss0r2: only 4 more passes to go on this part & i'm halfway there
05:57 AM XXCoder: some tools just cant work well lol
05:57 AM miss0r2: a dovetail cutter is one of'em
05:58 AM XXCoder: i cant run certain job prep because of huge drill
05:58 AM XXCoder: coworker told me it sounds like few dogs fighting in mill.
05:58 AM miss0r2: haha
05:58 AM XXCoder: thankfully I can run next 2 steps fine,
05:58 AM miss0r2: nice
05:58 AM miss0r2: I don't have coworkers, so I come here to bitch and moan :)
05:58 AM XXCoder: that one prep is quite dangerous lol
05:59 AM miss0r2: what does it involve?
05:59 AM XXCoder: almost 2" drill thats 16 inches long
05:59 AM miss0r2: that a bigboy tool
06:00 AM XXCoder: now picture that with 70 in/lb clamping
06:00 AM XXCoder: it cant do much clamping strength or it will deform
06:00 AM miss0r2: :o
06:00 AM miss0r2: I would just shit myself and go home
06:00 AM XXCoder: and its not even to final diameter, it still need even bigger boring head
06:00 AM XXCoder: that one is 2 feet long
06:01 AM miss0r2: shit
06:01 AM XXCoder: so long its inch away from plastic screen in tool storage area
06:01 AM XXCoder: and tool change moves fast lol scary face stab feelings.
06:01 AM miss0r2: I don't suppose you are allowed to snap a photo of that?
06:01 AM XXCoder: nope
06:01 AM miss0r2: Figures :) sounds awesome though
06:02 AM XXCoder: its one of largest tools used in shop
06:02 AM XXCoder: most insane I have used was 1' facemill
06:02 AM XXCoder: with 6" extend
06:02 AM miss0r2: not for the faint of heart :D
06:02 AM XXCoder: its very heavy I can barely lift it
06:02 AM XXCoder: it cant be used in toolchange it'd rip stuff up
06:02 AM miss0r2: thats what 320mm ish?
06:02 AM XXCoder: roughly 300mm = 1 feet
06:02 AM miss0r2: hehe, most of the tools you speak off I couldn't even fit on the mill
06:02 AM miss0r2: alright
06:03 AM XXCoder: most tools is tame at shop
06:03 AM XXCoder: 1 inch, half inch etc
06:03 AM XXCoder: on the small end is 1/32 ball endmill lol
06:03 AM miss0r2: what is that in science?
06:03 AM miss0r2: :)
06:04 AM miss0r2: 0.8
06:04 AM miss0r2: hehe
06:04 AM miss0r2: I have a drawer here with endmills down to 0.07mm ball
06:04 AM miss0r2: I only keep the realy small ones for shits and giggles. I have no way of running them :)
06:04 AM XXCoder: ya never needed smaller. 1/16 I use a lot :P engraving stuff
06:04 AM XXCoder: I got idea for ya
06:04 AM XXCoder: engraving stuff lol
06:05 AM miss0r2: with a 0.07mm? hahaha
06:05 AM XXCoder: just use some epoxy and rerun surface
06:05 AM XXCoder: then you got cool fine engravings lol
06:05 AM miss0r2: thats 0.0027"
06:05 AM XXCoder: ya
06:05 AM miss0r2: man, I don't have thinghing that can spin remotely fast enough to get use of that
06:06 AM miss0r2: thinghing= anything
06:06 AM XXCoder: ya would need serious rpm
06:06 AM XXCoder: 1/16 I use 10,000 rpm something. robodrill is great for that.
06:06 AM miss0r2: the place I got a handfull from drives'em at 47k rpm
06:07 AM XXCoder: for small machine I do recommand robodrill though you need temperate control
06:07 AM miss0r2: wtf is robodrill?
06:07 AM XXCoder: and I always run a "blank" (no part) to warm machine properly
06:07 AM XXCoder: its machine brand name
06:07 AM XXCoder: pretty dumb name
06:07 AM miss0r2: I repair machines for a living, and I have never seen/heard of one before
06:08 AM miss0r2: Must not be big outside of the US
06:08 AM XXCoder: yeah. its designed to be able to be operated by cnc arms lol
06:08 AM XXCoder: load unload
06:08 AM miss0r2: one could argue most cnc machines are
06:09 AM miss0r2: but also to be used by an operator
06:09 AM miss0r2: :)
06:09 AM XXCoder: sorta
06:09 AM pink_vampire: miss0r2: "robodrill" is a fanuc brand
06:09 AM XXCoder: hey pink
06:09 AM XXCoder: the difference is door is not removed
06:09 AM miss0r2: ahh alright.
06:09 AM miss0r2: hello pink_vampire
06:10 AM XXCoder: doors is designed to be able to close and open by arms
06:10 AM selroc: hi pink
06:10 AM miss0r2: I was out repairing a cnc machine, where the robot falsely thought the door was open...
06:10 AM pink_vampire: hi
06:10 AM pink_vampire: i just waked up
06:10 AM XXCoder: good morning
06:11 AM miss0r2: lets just say; after it had done its job, there was an open door
06:11 AM miss0r2: err.. no door
06:11 AM XXCoder: ow heh
06:11 AM miss0r2: Starting the last pass on the current part now...
06:11 AM XXCoder: https://www.youtube.com/watch?v=u7cBzMtEB1g
06:12 AM XXCoder: ones at place I work is not set to open like that, need addons
06:12 AM miss0r2: :D
06:12 AM miss0r2: bah... even on the springpass its running now it makes a racket when starting !
06:13 AM miss0r2: That cutter is going in the bin after this job is done
06:13 AM XXCoder: lol
06:13 AM XXCoder: https://www.youtube.com/watch?v=IKrlXyLQbwM btw another type
06:14 AM jthornton: give the cutter to someone you don't like
06:15 AM XXCoder: or death metal band looking for that sound
06:15 AM miss0r2: lol
06:24 AM miss0r2: XXCoder: This is the part fresh off the mill https://imgur.com/a/yBXK7ik
06:24 AM XXCoder: nice
06:26 AM miss0r2: 4 of those... I have another four units that are slightly less complicated and two semi complicated mounting plates.. I have to get this done by thursday, end of day, to get them annodized
06:26 AM jthornton: nice at least it's a male dovetail they are easier to machine than the slot
06:26 AM XXCoder: lol bet slot is a whole lot more fun
06:26 AM miss0r2: jthornton: indeed. The slots are much shorter
06:26 AM miss0r2: so, you can see I am somewhat in a rush here :)
06:27 AM XXCoder: nice! new unlisted clickspring video
06:28 AM XXCoder: "The Good The Bad and The Oiler"
06:28 AM XXCoder: lol
06:28 AM miss0r2: uhhh
06:30 AM XXCoder: i love pareon benefits heh
06:30 AM XXCoder: clickspring has one of best benefits for pareon. way more than others.
06:40 AM XXCoder: miss0r2: precision oil applicator apparently
06:40 AM XXCoder: 2 different kinds of oil
06:42 AM miss0r2: meh. can you link me?
06:43 AM XXCoder: not to unlisted one
06:43 AM XXCoder: the channel https://www.youtube.com/channel/UCworsKCR-Sx6R6-BnIjS2MA
06:44 AM miss0r2: how do I go about finding an unlisted one?
06:44 AM XXCoder: be pareon supporter :)
06:44 AM miss0r2: bah..
06:45 AM XXCoder: though theres ways to google unlisted videos
06:45 AM XXCoder: never looked that up so dunno
06:45 AM miss0r2: can't be bothered. :)
06:46 AM XXCoder: https://www.patreon.com/clickspring
06:46 AM XXCoder: lists to see what videos you can watch. and honestly it'd be one of better $1 you have spent.
06:47 AM miss0r2: I already waste enough time watching youtube... :)
06:48 AM XXCoder: 6 months so far of membership for me :)
06:48 AM XXCoder: longest is kurzgesagt and nurdrage both 7 months
06:48 AM XXCoder: oh and isaac arthur 7 months also lol
06:51 AM miss0r2: those are just words to me :)
06:51 AM XXCoder: those is excellent youtube channels
07:00 AM miss0r2: I just don't have powerfull enough speakers to enjoy youtube videos while this dovetail cutter is running
07:00 AM XXCoder: captions ;)
07:00 AM miss0r2: hehe, try doing that on an AvE video xD haha
07:02 AM XXCoder: tried to watch some ave eh
07:02 AM miss0r2: This cutter wold not qualify as a scookum choocher
07:03 AM XXCoder: found something you could do while its all noisy http://www.bluemilkspecial.com/comic/in-the-beginning/
07:03 AM XXCoder: its star wars with lots of humor. sometimes adult (but not ntfw) humopr
07:03 AM XXCoder: the very second comic contains adult comic
07:04 AM miss0r2: lol nice animation https://9gag.com/gag/aKxvV06
07:05 AM XXCoder: lol thats new. saw one where cat went out after
07:06 AM miss0r2: lol
07:06 AM XXCoder: if youre fan of star wars i HIGHLY recommand that webcomic
07:06 AM XXCoder: so many laughs
07:07 AM * miss0r2 is reading it as we speak
07:11 AM miss0r2: lmaf with the kenny character inside of R2D2
07:11 AM XXCoder: indeed
07:12 AM XXCoder: rereading it myself. lopve that webcomic. you got large arcive, 2009 to 2019
07:15 AM miss0r2: nice. I can recommends three; they are old and two of'em has stopped... but they are still there: hackles, biggerthancheese & userfriendly. all of those are computer geek stuff, but quite amusing
07:15 AM miss0r2: lol, hackles ended janurary 2004
07:16 AM XXCoder: third one is known
07:16 AM XXCoder: first is also known
07:16 AM miss0r2: well, biggerthancheese is not realy about computers
07:17 AM miss0r2: but popculture & violence
07:17 AM XXCoder: bigger than cheese also ended
07:17 AM XXCoder: bu will read later
07:18 AM miss0r2: yeah, hackles & BTC has ended
07:42 AM pink_vampire: hi
07:48 AM miss0r2: I need a new enclosure solution for the cnc. The one I am currently running is loosing a little water all the time. When its been running non-stop for 8 hours its beginning to form puddles on the floor
07:49 AM jdh: catch pan + pump!
07:50 AM miss0r2: jdh: hehe, that would be quite impractical. it would have to measure 3x4 meters
08:03 AM miss0r2: down to only missing 2x400mm dovetails to be cut now
08:03 AM miss0r2: This is taking too long, and I have to end my work day in a few moments. I will be back tonight to continue on this hellova deed
08:36 AM R2E4: EVA
09:10 AM CNC_Brian: Guys, can anyone explain to what the "sudo make setuid" when building RIP actually does
09:11 AM CNC_Brian: If I move the compiled binaries between machines or clone the disk do I need to run this command again?
09:12 AM SpeedEvil: I have not read the specivfic docs. In general, it would be for making something run as a specified user, by manipulating the permissions on the binary.
09:12 AM SpeedEvil: Perhaps - if the permissions do not remain the same on restore.
09:13 AM CNC_Brian: getting some horrible latency figures when I copy file form my dev box down onto the pc running my machines.
09:20 AM rmu: CNC_Brian: normal copy operations, esp. over the net, won't work, you have to run it again or replicate owner/permissions manually
09:20 AM rmu: it: make setuid
09:20 AM rmu: "sudo make setuid" runs "make setuid" as root
09:21 AM rmu: make changes owner of the binary that needs to run with realtime to root and sets the "setuid" bit, so the binary runs as the owner (root) regardless of the user that invokes said binary
09:24 AM CNC_Brian: Ah ok
09:25 AM CNC_Brian: So if I build on a dev machine I need to reset the permissions on the files
09:39 AM rmu: depends on how you copy
09:39 AM rmu: in general, if you copy as user (not as root) you will net to re-set the permissions and owner
09:40 AM rmu: don't copy as root.
10:24 AM flyback: https://www.youtube.com/watch?v=fNuI6keQXYA
10:25 AM pink_vampire: just amazing
10:31 AM flyback: THEY DIDN'T have good starting caps back then
10:31 AM flyback: or windings that would tollerate stalled for a few seconds
10:31 AM flyback: so they spin the housing up first to put backspin on the shaft
10:32 AM pink_vampire: i love old technology
10:32 AM flyback: enjoy :)
10:33 AM flyback: oh I got something for you then
10:33 AM flyback: and no that's not a pickup line
10:33 AM flyback: https://www.youtube.com/watch?v=f8b9FqPKTjI
10:33 AM flyback: tried to yrs to find a video of one of these
10:34 AM flyback: it's a dc motor on one side and ac on the other
10:34 AM flyback: it's how they did conversions before electronics
10:35 AM pink_vampire: the bearing housing look like forged metal
10:35 AM pink_vampire: maybe cast?
10:35 AM pink_vampire: it is amazing
10:37 AM flyback: could be I dunno sorry
10:38 AM flyback: they also had an insteresting side effect that is still used today although used with a system without brushes etc
10:38 AM flyback: the rotating mass stores a small amount of energy
10:38 AM flyback: which smooths out fluxutations
10:42 AM flyback: rotary condensors
10:42 AM flyback: which is a special induction motor usually in a sealed env without a shaft
10:42 AM flyback: used to buffer fluxutations
10:42 AM flyback: they have ups's this way also
10:42 AM flyback: only last a min or so
10:42 AM flyback: but they can constant smooth power or load demands
10:42 AM flyback: without wearing out a battery
10:44 AM gregcnc: like a rotary phase converter?
10:45 AM pink_vampire: i know people use rotary converters to convert from 1 phase to 3 phase
10:46 AM gregcnc: i would imagine it's the same concept, but no pahse conversion
10:46 AM pink_vampire: of course
10:47 AM gregcnc: any motor becomes a generator as soon as the input voltage drops below BEMF
10:47 AM pink_vampire: 2 din rails are empty!
10:47 AM gregcnc: just need a flywheel to store some energy
10:50 AM gregcnc: pink_vampire are you replacing everything?
10:50 AM flyback: gregcnc, pretty much
10:50 AM flyback: although they optimize it for energy storage
10:50 AM flyback: so the rotor might be composit etc
10:51 AM flyback: this one flywheel ups at a university is on the same shaft as a diesel genset
10:52 AM flyback: if they genset refuses to start they have a clutch to dump the flywheel into the genset
10:52 AM gregcnc: makes sense
10:53 AM flyback: the other big advantage to a composite rotor is if it shit itself
10:53 AM flyback: it turns to sand basically
10:53 AM flyback: not a solid chunk of metal flying into someone's face
10:53 AM pink_vampire: gregcnc: i'm rearranging stuff to make the wires go ij more logic way, and also adding a wire duct for the motor / high power stuff
10:54 AM gregcnc: you're talking modern high speed composite flywheel in a vacuum chamber?
10:55 AM flyback: yeah
10:56 AM flyback: for some rotary ups's
10:56 AM flyback: not all
10:56 AM flyback: I geuss the idea was a) for maximum energy storage b) less kill factor
10:57 AM gregcnc: the motors used are also designed to run at high speed and very high efficiency
10:57 AM flyback: yes
10:57 AM gregcnc: I think BLDC
10:57 AM flyback: yes
10:58 AM flyback: but there weew ones that were just a giant optimized ac induction motro
10:58 AM gregcnc: oh ok
10:59 AM gregcnc: there is a guy on a forum that "I think" designed the motors for the BLDC type
10:59 AM flyback: https://en.wikipedia.org/wiki/Synchronous_condenser
11:05 AM pink_vampire: i just got 1.3mm mechanical pencil , and it is soooo nice
11:10 AM flyback: bbl
11:13 AM CNC_Brian: Just trying to get my mesa 7i97 card working with 2.8 and hm2_eth is complaining about unrecognised board?
11:17 AM JT-Shop: what is the exact error
11:20 AM fragalot: 'allo!
11:27 AM CNC_Brian: Dosnt recognise the new board
11:28 AM fragalot: ! I finally figured out why cut extrudes did not work in fusion360
11:29 AM fragalot: turns out you just need to break the link of the imported components
11:29 AM CNC_Brian: Have replaced the rtlib files for newer ones now getting rtapi_shmem_new problem
11:30 AM CNC_Brian: Guess I cant just mix and match files
11:32 AM JT-Shop: 7i97 wow that is a new card
11:37 AM CNC_Brian: Yes it the latest on I think. Seems good value so though I would give it a try
01:31 PM gloops: damn i lost my painstakingly created blender skull when windows dumped temp files
01:50 PM pink_vampire: HOW??????
01:53 PM gloops: im not really sure lol, powered off - restarted, file not there
01:54 PM gloops: stupid to save it in temp folder
01:54 PM fragalot: have you attemped any form of file recovery
01:54 PM roycroft: so, folks, i'm aware that the folks on the knifemaking forums don't always have a good grasp of how things work, but there seems to be a repeated meme regarding motors for belt grinders that makes me wonder if i'm missing something
01:55 PM fragalot: assuming you've not used your pc too much since
01:55 PM fragalot: roycroft: what's that?
01:55 PM roycroft: the claim is that for a belt grinder a tefc motor is essential, and that nothing else will work for a long period of time
01:55 PM roycroft: the motor i just bought is odp
01:55 PM roycroft: but i plan on making a shroud for it
01:55 PM roycroft: to protect it from the grinding grit
01:55 PM gloops: fragalot ive already got a new mesh drawn
01:55 PM fragalot: tefc just lasts longer in a grinding dust environment
01:56 PM roycroft: the claim on the knife forums is that even with a shroud an odp motor will eventually get stuffed up with grit and failw
01:56 PM fragalot: and if you run it at a low RPM, you really do want the external fan
01:56 PM roycroft: while a tefc motor is immune to that
01:56 PM roycroft: i don't recall ever seeing a tefc motor that has a filter in it
01:57 PM fragalot: it's mosty the bearings that suffer
01:57 PM roycroft: it seems to me that while it does an effective job at keeping grit out that falls on the outside of the motor, if there is airborne grit a tefc will suck it in just as well as an odp motor will
01:57 PM fragalot: and brushes, if applicable
01:57 PM roycroft: am i wrong there?
01:57 PM roycroft: and if i make a shroud that goes around the motor it won't suck in as much dust as if i left it open
01:57 PM fragalot: the fan will, but the motor bearings are better protected in a tefc
01:57 PM roycroft: ok
01:58 PM roycroft: but if i put a filter on the air inlet side of the motor
01:58 PM fragalot: you increase life
01:58 PM roycroft: then my shrouded, filtered motor would probably protect the bearings better than an unfiltered tefc motor, right?
01:58 PM fragalot: assuming you don't block airflow too much when you run at low rpm
01:58 PM roycroft: i'd just have to check the filter and change it occasionally
01:58 PM roycroft: yeah, running at low rpm can be an issue
01:58 PM roycroft: i'm unlikely to run at low rpm for extended periods of time
01:59 PM roycroft: and if the motor starts getting hot i can always add an external fan (along with the filter)
01:59 PM fragalot: yep
01:59 PM roycroft: i got what i got because it was cheap and because it has a 56z frame
02:00 PM roycroft: the z meaning in this case 7/8" shaft
02:00 PM roycroft: most 3hp motors have a 1-1/8" shaft, which is problematic for mounting an off-the-shelf drive wheel
02:00 PM roycroft: so i'm good to go
02:01 PM roycroft: if i am sucking in a lot of grit into the shrouded motor i need to worry about sucking grit into the vfd as well
02:01 PM roycroft: i don't want to mount the vfd on the other side of the room
02:01 PM roycroft: i want it near the grinder
02:02 PM fragalot: be reasonable with the placement (ie. not under the belt) & just clean it out periodically
02:02 PM roycroft: i'm also likely to build a shield around most of the belt
02:02 PM roycroft: so that most of the grit will just go straight down toward the floor
02:02 PM roycroft: when the grinder is in the vertical position
02:02 PM fragalot: shoot it into a bucket & extractor
02:02 PM roycroft: yeah, it won't be near the belt
02:02 PM roycroft: right, that's what i'm thinking
02:02 PM roycroft: a bucket of water underneath the grinder
02:03 PM roycroft: and shield the belt except at the working bits
02:03 PM roycroft: it should shoot almost everything straight down into the bucket of water
02:03 PM roycroft: my current belt grinder does not shoot sparks and grit and crap all over the place
02:03 PM roycroft: that stuff mostly goes straight down
02:04 PM roycroft: the knifemaking forums can be interesting
02:04 PM fragalot: that's what happens when a single obervation becomes lore
02:04 PM roycroft: there's a lot of argument about motor size, with many folks claiming a 1/3hp washing machine motor is powerful enough for all grinding needs
02:04 PM fragalot: not important why, but this is how it is, because someone said so once
02:04 PM roycroft: and folks saying that a 3hp motor is insane
02:05 PM roycroft: i have this annoying personality trait of being fact and evidence driven
02:05 PM fragalot: 3hp is not insane if you want to be able to lean into it with a 20grit belt
02:05 PM roycroft: and never taking anecdotes as fact
02:05 PM roycroft: i think 3hp is the perfect size motor for it
02:06 PM roycroft: 2hp would be ok
02:06 PM roycroft: but 3hp will be better
02:06 PM roycroft: 5hp, that's getting into overkill imo
02:06 PM roycroft: and it's hard to find an affordable 5hp vfd with single phase input
02:07 PM roycroft: anecdotes are not to be rejected, btw
02:07 PM roycroft: they are research opportunities though, and not facts
02:07 PM fragalot: they are not to be rejected, but they are not to be repeated blindly
02:07 PM fragalot: or taken as the only truth
02:07 PM gloops: on the facebook group there is a strong school of thought in favour of 3hp
02:07 PM gloops: although many builds are much less
02:08 PM fragalot: you can get by with less
02:08 PM roycroft: yes
02:08 PM roycroft: i was going to build with the 2hp motor i have
02:08 PM roycroft: and 1hp would probably even get me by
02:08 PM roycroft: a fractional hp motor, imo, is not appropriate for a grinder the size i'm building
02:08 PM fragalot: my little belt grinder is something like 130W, and it gets the job done
02:08 PM fragalot: the only issue is that said job takes about 10 times longer
02:08 PM fragalot: if not more
02:08 PM gloops: 1.5-3 seems within acceptable parameters, less is not enough
02:09 PM roycroft: i am getting old
02:09 PM roycroft: i don't have as much time as i used to
02:09 PM fragalot: :D
02:09 PM roycroft: i need to make the most of the time that i have
02:10 PM roycroft: i say, having spent a full hour last night flattening the back of a single chisel
02:10 PM roycroft: and that job is not quite done yet
02:10 PM roycroft: i have another 10-15 minutes of lapping to do before it's truly flat
02:11 PM roycroft: a belt grinder could probably have gotten it mostly flat in a matter of a minute or two, leaving me with only 15 minutes or so of hand lapping
02:11 PM fragalot: it could have gotten it flatter, but in my experience belt grinders do not grind flat well
02:11 PM roycroft: fortuantely i do not get new chisels often, as i have most of what i ever need
02:11 PM roycroft: hand lapping will always be needed
02:11 PM fragalot: and i've found myself cheating & grinding the back of cheap chisels in the japanese style
02:12 PM fragalot: hollow it out, save yourself an hour of lapping
02:12 PM roycroft: yes, that's a great idea
02:12 PM roycroft: until you've been using the chisel for 20 years
02:12 PM fragalot: then again, i've quit buying shit chisels
02:12 PM roycroft: and have honed it back to the hollow
02:12 PM fragalot: then that chisel has served you well & you deserve an upgrade
02:12 PM roycroft: i have some japanese chisels that are useless because of that
02:13 PM roycroft: most of my chisels are robert sorby
02:13 PM fragalot: also, if you can't get it to work again, the hollow was too deep
02:13 PM roycroft: folks complain about them because they're not as hard as some
02:13 PM roycroft: but i've found that they work very well
02:13 PM roycroft: and i don't mind that i need to hone them more often than harder ones
02:13 PM roycroft: they never chip out
02:13 PM roycroft: and are easy to hone
02:13 PM roycroft: we're not talking about a big difference
02:13 PM roycroft: sorby are around rockwell 61
02:14 PM fragalot: i've got a selection of japanese, 2 cherries, MGH, and the ultra cheap yet pretty damn good no-name beaters
02:14 PM roycroft: the "hard" chisels to which folks compare them are usually rockwell 62 or 63
02:14 PM roycroft: some japanese chisels are rockwell 64 at the working end
02:14 PM gloops: i just got used to being called 'rough' lol
02:14 PM fragalot: with ultra cheap i'm talking €1 for a 12mm chisel, that actually works really well
02:14 PM roycroft: i just got some 2 cherries skew chisels
02:14 PM roycroft: 12mm
02:14 PM roycroft: left and right
02:14 PM roycroft: those are the ones i'm working on right now
02:14 PM roycroft: the steel is good
02:15 PM roycroft: but 2 cherries very annoyingly buff their chisels to a mirror finish
02:15 PM roycroft: but they don't grind them flat first
02:15 PM fragalot: you can buy them ground
02:15 PM roycroft: and the buffing rounds them over a bit
02:15 PM roycroft: i knew going in that i'd have to reshape them before i could use them
02:16 PM roycroft: i looked for unpolished ones
02:16 PM fragalot: that's why you buy the ground ones, not the polished ones :P
02:16 PM gloops: https://www.ebay.co.uk/itm/7x-old-large-wood-chisels-green-oak-framing-woodworking-tools-marples-shed-find/192845112458?
02:16 PM roycroft: it's really hard to find unpolished skew chisels
02:16 PM roycroft: so i got what i could get
02:16 PM fragalot: roycroft: https://www.fine-tools.com/schraegbeitel.html
02:16 PM gloops: stuff like that is on ebay endlessly, all the old chisels are far superior to modern ones
02:16 PM roycroft: and planned on doing a lot of lapping and honing before they would be useful
02:17 PM roycroft: old sheffield steel chisels are great
02:17 PM roycroft: fragalot: those chisels are not in the usa
02:17 PM gloops: £1 each on the car boot sale near me (15 mile from sheffield)
02:17 PM roycroft: i should preface my previous statement by saying that in the usa it's hard to find unpolished 2 cherries skew chisels
02:17 PM fragalot: roycroft: Welcome to getting useful links that aren't very useful. :)
02:18 PM roycroft: i would love to go on a car boot sale trip to the uk
02:18 PM roycroft: i would find so much amazing stuff for so cheap
02:18 PM fragalot: I would love to go to a swap meet that keith rucker & abom appear to find
02:18 PM fragalot: or the auctions
02:18 PM gloops: https://www.ebay.co.uk/itm/5-VINTAGE-MORTICE-WOOD-CHISELS-MARPLES-SORBY-CARPENTER/132960450852? i might have a go at those
02:19 PM roycroft: anyway, i got what i got
02:19 PM roycroft: and they're polished
02:19 PM roycroft: or soon to be were polished :)
02:19 PM roycroft: one of them has a back that is no longer polished, but it is almost flat now
02:19 PM gloops: big one is f... though
02:20 PM roycroft: https://www.amazon.com/Robert-Sorby-Mortise-Overall-Sheffield/dp/B06Y5RCHW5?SubscriptionId=AKIAILSHYYTFIVPWUY6Q&tag=duckduckgo-osx-20&linkCode=xm2&camp=2025&creative=165953&creativeASIN=B06Y5RCHW5
02:20 PM fragalot: roycroft: I remember spending 3 days lapping my stainly €4 plane
02:20 PM roycroft: that's one of my moritse chisels
02:20 PM fragalot: #4*
02:20 PM roycroft: i like big, beefy mortise chisels
02:20 PM fragalot: my arms hated me
02:20 PM roycroft: and that thing is a monster
02:20 PM fragalot: and it's still not flat >.>
02:21 PM roycroft: the thing is, fragalot, you should only have to do that once ever
02:21 PM roycroft: per tool
02:24 PM fragalot: in my opinion you shouldn't even need to do it once
02:24 PM fragalot: the fact that you do sickens me
02:24 PM roycroft: yeah
02:24 PM roycroft: and i get why
02:24 PM roycroft: i don't agree, but i get it
02:24 PM fragalot: tuning up, fine
02:24 PM fragalot: but having to rough it down.. no.
02:24 PM roycroft: modern toolmakers do all their grinding before heat treating, because it's easier to do while the steel is still soft
02:24 PM roycroft: so it's cheaper to manufacture that way
02:24 PM roycroft: and that's fine
02:24 PM gloops: the irons in the old wooden planes are often superb, you can get a scary edge on them
02:24 PM roycroft: it would be nice to have the option of getting tools that are ground after heat treatment
02:24 PM roycroft: they are, gloops
02:24 PM gloops: plus 3 times thicker
02:24 PM roycroft: especially norris and spiers
02:24 PM roycroft: but some modern steels are even better than the old-time stuff
02:24 PM roycroft: lie-nielsen use a2 steel that's cryogenically treated
02:24 PM gloops: at a cost roycroft
02:24 PM roycroft: and their plane irons are amazing
02:24 PM roycroft: yes
02:24 PM fragalot: I quite like the axminster rider planes
02:24 PM fragalot: and veritas
02:24 PM roycroft: lee valley/veritas use some fancy new alloy that costs 2x as much as the good a2 stuff
02:24 PM fragalot: both are very decent, but not extortionately priced
02:24 PM pink_vampire: gloops: I'm sorry that i'm on and off like that today, I'm working on the panel the same time
02:25 PM roycroft: i really like lie-nielsen planes for modern planes
02:25 PM fragalot: roycroft: thing is though, a lot of tools you buy today aren't even ground flat.. it's just been pushed up to a belt sander by hand to make it look nice
02:25 PM gloops: oh its no problem pink_vampire, i know youre busy :)
02:25 PM roycroft: they are expensive but they are amazing
02:25 PM fragalot: my table saw for example looks like they basically used a handheld flapwheel to surface it
02:25 PM roycroft: or the 2 cherries that are rough ground, lightly honed, and then polished with the grinding marks left on
02:26 PM roycroft: make them smooth before polishing them, mmkay?
02:26 PM roycroft: actually, just keep them the hell away from a polishing wheel
02:27 PM fragalot: yeah
02:27 PM roycroft: do final honing on a japanese water stone and you'll get a mirror finish without using a polisher
02:28 PM fragalot: I used to do that too until i found that I couldn't tell the difference very well between doing up to a 12k stone, or going straight from 2k to a CrOx leather strop
02:28 PM roycroft: anyway, the belt grinder would save me some of the initial time flattening
02:28 PM roycroft: but certainly not all of it
02:28 PM fragalot: s/crox/white polishing compound)
02:28 PM roycroft: i was essentially doing shaping on the diamond plate last night, not sharpening
02:28 PM fragalot: for the back I still use the stone, but for the cutting edge... eh.
02:29 PM roycroft: i use dmt diamond plates for initial sharpening
02:29 PM fragalot: same
02:29 PM roycroft: i have x-coarse, coarse, medium, and fine
02:29 PM roycroft: i go through all those
02:29 PM roycroft: and when i'm done with the fine plate i move over to an 8000 grit japanese waterstone
02:29 PM fragalot: I don't any more, just medium, fine, strop, done.
02:29 PM roycroft: from there i do final stropping on leather
02:30 PM fragalot: is there a difference in sharpness? probably. can I tell the difference personally? not really.
02:30 PM roycroft: after the intial sharpening i usually just touch up on the water stone and lap
02:30 PM roycroft: the diamond plates are just for initial sharpening
02:31 PM roycroft: after the microbevel gets too big from honing too many times i go back to the diamond plates to reestablish it
02:31 PM roycroft: i like to grind both plane irons and chisels at 25 degrees, and then put a 27 degree microbevel on them
02:32 PM fragalot: another thing I don't bother with is sharpening jigs once the edge is nice & square
02:32 PM roycroft: the big mortise chisels i grind at 30 degrees with a 32 degree microbevel
02:32 PM fragalot: I don't mind a slight camber
02:32 PM roycroft: i have the lie-nielsen jig
02:32 PM roycroft: it's nice
02:32 PM roycroft: very expensive, but works brilliantly
02:32 PM roycroft: it makes it so that i don't have to even think about it
02:32 PM fragalot: i've got the veritas one
02:32 PM roycroft: i just stuff the blade in the jig, set it to the desired angle, and go
02:32 PM roycroft: it's very fast
02:33 PM roycroft: i have the mark i
02:33 PM roycroft: but not the mark ii
02:33 PM roycroft: the mark i will be useful for the skew chisels
02:33 PM fragalot: I only really use the jig for new or really bad chisels
02:33 PM roycroft: but i don't like top clamp jigs - too easy for the blade to move
02:33 PM fragalot: during normal use & touch-ups I just freehand it & don't even fret too much about the exact angle
02:33 PM roycroft: and the eclipse is just too sloppy to work well
02:34 PM fragalot: just go for it paul sellers style
02:34 PM roycroft: the lie-nielsen is basically the eclipse design done to machinist standards
02:34 PM fragalot: hehe
02:34 PM roycroft: and it's made of stainless steel
02:35 PM roycroft: https://www.lie-nielsen.com/nodes/4239/honing-guide
02:36 PM roycroft: very expensive, but worth every penny
02:37 PM roycroft: and if you consider that i have over $400 invested in those diamond plates, $250 for a jig and all the extra jaws i needed for it isn't totally out of line
02:37 PM fragalot: yea I think i've got over 2 grand in a drawer in just sharpening materials
02:38 PM fragalot: it gets out of hand quick :D
02:39 PM roycroft: i bought the jet clone of the tormek sharpener years ago
02:39 PM roycroft: i really never used it much
02:39 PM roycroft: i don't like hollow grinding my tools
02:39 PM roycroft: especially ones that i use a lot - hollow grinding weakens the edge
02:39 PM fragalot: i'm not sure i'd mind, with the way I hand sharpen after
02:40 PM fragalot: which usually ends up with a slight convex grind
02:40 PM roycroft: i'd rather spend more time grinding a good, solid edge and keeping it honed well
02:40 PM fragalot: and in your case if you jig it up, you wind up with a faster flat bevel where it matters
02:40 PM roycroft: all hollow grinding does is save time up front on the initial sharpening
02:40 PM fragalot: and from a practical standpoint, i'm not sure if it is still really weaker at that point
02:41 PM roycroft: and imo that does not offset the weakening of the edge that it introduces
02:41 PM roycroft: so i'll probably sell that jet
02:41 PM fragalot: also, if you set the angle right, i'm also not convinced the hollow grind is any weaker
02:41 PM fragalot: assuming the start of it has the same 25°
02:41 PM roycroft: right now, all i use it for is the initial grind when i have to reshape an edge
02:41 PM roycroft: i'll get it square and ground roughly to the correct angle with the jet
02:42 PM roycroft: then i'll take it to the diamond plates and put a proper flat edge on it
02:42 PM roycroft: for paring and light duty chisels it's not a big deal
02:42 PM roycroft: nor with plane blades
02:42 PM roycroft: it's with those big mortising chisels where it really weakens the edge a lot
02:42 PM fragalot: I mortise with my "light duty chisels"
02:42 PM roycroft: but i really wail on those chisels with a large mallet
02:42 PM fragalot: never had any problems
02:43 PM roycroft: anyway, it is lunch time
02:43 PM fragalot: not since using that method paul sellers showed in his video
02:43 PM fragalot: roycroft: https://www.youtube.com/watch?v=q_NXq7_TILA <-- this is the method I use
02:45 PM roycroft: i'll check it out after lunch
02:45 PM roycroft: paul sellers is a good woodworker and a good instructor
02:45 PM fragalot: enjoy
02:45 PM roycroft: i always enjoy watching him
02:45 PM roycroft: but for now mah belly needs filling
04:00 PM roycroft: so my method of cutting mortises is similar to what paul sellers does
04:00 PM roycroft: with a couple differences
04:00 PM roycroft: i don't cut right to the edges of the mortise on the first go
04:00 PM roycroft: i like to chop out the mortise, leaving a tiny bit on all sides for cleanup
04:00 PM roycroft: then i pare down at the knife line
04:01 PM roycroft: i also have a swan-neck chisel for scooping the gunk out of the mortise
04:01 PM roycroft: and i prefer that to using a smaller chisel
04:01 PM roycroft: both are minor variations
04:01 PM roycroft: i've never chopped mortises starting in the middle and working to both ends
04:01 PM roycroft: i have always started at one and and worked to the other
04:01 PM roycroft: i don't remember how/why i started doing it that way
04:02 PM roycroft: but i don't think i've ever done it any other way
04:14 PM Deejay: gn8
04:28 PM * JT-Shop has determined that one end of the generator wiring is wrong... now to decide which end is wrong and fix it
04:28 PM Tom_L: ?
04:36 PM JT-Shop: the generator is 3 phase and my SO cord is 4 wire cord but when it gets to the panel it's single phase so when I moved the generator then put it back I made the wrong guess
04:37 PM Tom_L: ahh
04:41 PM Tom_L: how do you clone a linux hdd?
04:41 PM Tom_L: i wanna copy what i've got to a test drive to update to 2.8
04:42 PM JT-Shop: you just make a copy of the ~/linuxcnc directory
04:42 PM JT-Shop: and all the subdirectories under linuxcnc
04:43 PM Tom_L: i wanna keep wheezy too
04:45 PM roycroft: you're wanting to clone the entire disk to a fresh disk?
04:46 PM R2E4: evening, morning,afternoon
04:46 PM JT-Shop: Tom_L: explain what your wanting to do
04:46 PM Tom_L: clone the whole hdd to another one
04:46 PM roycroft: ok
04:47 PM Tom_L: i may just use ghost
04:47 PM JT-Shop: dd or what is that software hmmm
04:47 PM roycroft: debian, and debian-like operating systems use multiple partitions for the os
04:47 PM roycroft: easiest would be to boot from a livecd
04:47 PM roycroft: then
04:47 PM R2E4: can someone help with halui.max-velocity? Im trying to set jog speed for external buttons. nothing I am trying is working. it is set to 20 by halui.max-velocity.value
04:47 PM JT-Shop: Tom_L: you don't have an extra hd?
04:47 PM Tom_L: i do
04:47 PM Tom_L: several probably
04:47 PM roycroft: dd if=/dev/rsda of=/dev/rsdb bs=2m
04:48 PM JT-Shop: just copy your config and swap drives
04:48 PM roycroft: you want to copy the raw devices
04:48 PM roycroft: not the block special devices
04:48 PM roycroft: so make sure it's /dev/rsda, not /dev/sda
04:48 PM roycroft: your /boot will be in sda1
04:48 PM JT-Shop: R2E4: can you paste.ubuntu.com what you've tried
04:48 PM roycroft: root usually in sda2
04:48 PM roycroft: etc.
04:48 PM Tom_L: next part of it is: will it being a ssd matter?
04:48 PM roycroft: but rsda would be the whole disk
04:49 PM roycroft: it might
04:49 PM roycroft: but i think ssds do their remapping magic transparently, in which case it doesn't matter
04:49 PM R2E4: The machine is in the other building not on network yet.
04:49 PM roycroft: other than that it will go a lot faster than if is it were not an ssd
04:50 PM roycroft: make 100% certain you know which disk is your source drive
04:50 PM R2E4: but: setp jog-speed 200, setp halui.axis.jog-speed 200
04:50 PM roycroft: and do not accidently write to it
04:50 PM roycroft: i am now not responsible for anything you do :)
04:50 PM Tom_L: yeah i've done this type of thing before
04:50 PM JT-Shop: R2E4: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_Remote_Pendant
04:50 PM roycroft: but what's important is that you do not try to do it using the live os
04:50 PM JT-Shop: that's how I set jog speed on my pendant
04:50 PM roycroft: that's why i said to do it from a livecd
04:51 PM roycroft: bs=2m can be whatever you want, actually
04:51 PM roycroft: it's just a lot faster to read/write in big chunks like that instead of physical sector by physical sector
04:51 PM roycroft: faster by maybe two orders of magnitude
04:52 PM TurBoss: pv -tpreb /dev/sda | dd of=/dev/sdc
04:52 PM TurBoss: shows progress
04:52 PM roycroft: or just trust that it's doing the right thing :)
04:53 PM roycroft: if the source is a ssd then there is not going to be all that much to clone anyway
04:53 PM roycroft: probably 128GB or so
04:53 PM roycroft: that won't take very long
04:53 PM roycroft: even 1TB won't take all that long
04:54 PM roycroft: just start the copy and go have a refreshing beverage while waiting for it complete :)
04:54 PM R2E4: jthornton: halui.jogspeed doesnt exist anymore halui.axis.jog-spped is what is used, and I have tried setting that.
04:55 PM JT-Shop: hmm did you try setting it from the show hal window?
04:55 PM JT-Shop: looks like someone added a dash in the name lol
04:55 PM R2E4: no, didnt know you couold...lol I checked it from there....
04:56 PM JT-Shop: no, I have it right it's jog-speed in my example
04:56 PM JT-Shop: yea you can just set the pin with setp pin-name value
04:56 PM JT-Shop: it won't get saved but good to test with
04:57 PM R2E4: yeah, thats my bad but its not halui.jog-speed, it doesnt exist
04:57 PM R2E4: ok. Ill try that
04:57 PM JT-Shop: I'll take a look downstairs I have master running down there but first I need to finish wiring up the generator before dark
05:14 PM jthornton: R2E4: it's halui.joint.jog-speed in master
05:14 PM R2E4: https://paste.ubuntu.com/p/NMdvzH4Xhh/
05:15 PM R2E4: Thats before world mode when you just turn machine on I thought.
05:15 PM R2E4: I'll try it
05:16 PM jthornton: oh my I see there is both axis and joint jog speed
05:22 PM jthornton: R2E4: if you look at the man page for halui you can see that there is axis and joint jog pins, I would assume that the axis pins would not work until your out of joint mode
05:25 PM R2E4: you cant change it until your out of joint mode? Actually the external buitton doesnt work until your out of joint mode
05:26 PM jthornton: and just putzing around with the axis gantry sim you can't jog any axis with a negative home sequence
05:27 PM R2E4: jthornton: I setp halui.joint.jog-speed, it changed but it doesnt do anything. even while in joint mode
05:27 PM R2E4: I have this working in 2.5 3 or 4 years ago on my VMC and it is still working great.
05:27 PM jthornton: are you using joint plus/minus to jog
05:28 PM R2E4: jog-x-plus /minus
05:28 PM jthornton: axis jog won't work in joint mode only world mode
05:29 PM R2E4: thats what I want. It is working, but running at 20. I cant change it.
05:29 PM R2E4: my paste: https://paste.ubuntu.com/p/NMdvzH4Xhh/
05:30 PM R2E4: it seems you cant set it while it is connected to signal jog-speed
05:31 PM R2E4: But I dont want to have to set it then connect after axis is running
05:31 PM jthornton: are you doing a setp while it's connected to a signal?
05:31 PM R2E4: yeah, I see you cant....now
05:31 PM jthornton: first you have to unlink then you can setp
05:32 PM R2E4: I tried setting it before it gets connected and it didnt work
05:32 PM jthornton: as soon as it get connected to something it takes that value
05:32 PM R2E4: so unlink=>setp=> net ?
05:33 PM jthornton: http://linuxcnc.org/docs/devel/html/hal/basic-hal.html#_unlinkp
05:33 PM jthornton: http://linuxcnc.org/docs/devel/html/hal/basic-hal.html#_setp
05:33 PM R2E4: So it should work if I setp before it gets connected. Thats what I tried and it didnt work
05:36 PM jthornton: just to be clear your setting the joint jog speed and using the joint jog plus/minus?
05:37 PM R2E4: no the axis, joint is for joint mode before I home.
05:37 PM R2E4: is my understanding
05:38 PM jthornton: one thing I just verified is you can halui axis jog an axis unless it's homed
05:39 PM jthornton: I have no problem changing the speed using halui.axis.jog-speed
05:39 PM R2E4: yes thats right. I want to use the buttons after I home. so it is halui.axis.jog-speed
05:40 PM R2E4: which is connected to jog-speed signal and it gets set to 20
05:40 PM jthornton: how are you changing the halui axis jog speed?
05:41 PM R2E4: I am not, thats the problem, its at 20 because thats what is default. If you look at jog-speed in halshow you see that it is connected to two pins,
05:41 PM jthornton: default is 0
05:42 PM jthornton: which pins?
05:42 PM R2E4: my jog-speed is 20
05:42 PM R2E4: halui.axis.jog-speed and halui.max-velocity.value
05:43 PM jthornton: what is the net line for halui.axis.jog-speed
05:46 PM R2E4: net jog-speed halui.axis.jog-speed
05:46 PM jthornton: what else is connected to the jog-speed signal?
05:48 PM R2E4: jog-speed in halshow shows jog-speed => halui.axis.jog-speed <= halui.max-velocity.value
05:48 PM R2E4: halui.max-velocity.value is set to 20 somewhere, probably hardcoded as default which is my guess
05:49 PM jthornton: why is halui.max-velocity connected to jog speed?
05:50 PM jthornton: it's not hard coded if not connected to anything halui.max-velocity is 1
05:51 PM R2E4: I dont have halui.max-velocity.value anywhere in my hal files
05:53 PM jthornton: it's got to be in there somewhere open a terminal in your configuration directory and do grep -irl 'halui.max-velocity' *
05:59 PM jthornton: using a couple of pyvcp buttons and a checkbox this works to set jog speed https://paste.ubuntu.com/p/chknt6Vf2J/
06:02 PM R2E4: jthornton: I am always wrong...... halui.max-velocity.value was connected in xhc wireless pendant hal file...... dOH!!!
06:02 PM R2E4: thanks for helping me find it
06:02 PM jthornton: grep is your friend lol
06:03 PM R2E4: jthornton: I have some mesa orders coming up. sold a plasma I have to build and a vmc retrofit.
06:03 PM jthornton: how do you plan on setting the jog speed?
06:03 PM jthornton: cool
06:03 PM R2E4: ALready did it and it works now
06:03 PM jthornton: ok great
06:04 PM jthornton: time for me to do a bed check on the chickens and lock them down :)\
06:04 PM R2E4: thanks again C-yall......
07:30 PM _unreal_: HELLO
07:30 PM _unreal_: I'm almost there
07:31 PM _unreal_: I I'm about to dump a new image to my SD card for my tinker board then my next step is getting a real time kernel built
07:31 PM _unreal_: but I have to get the display and a few other things figured out
07:32 PM _unreal_: writing image now
08:19 PM miss0r2: ahh. little over 3 in the morning, and I am back in the shop
08:33 PM Lcvette: https://youtu.be/GuHRYzsR4Pc
08:34 PM Lcvette: thanks to turboss!!
08:49 PM Tom_L: nice
08:53 PM miss0r2: you ever know the feeling, that this will be a long day? :)
09:00 PM tiwake: trying to get my work place to buy one of these https://www.darex.com/v-390-drill-sharpener.html
09:01 PM tiwake: they have a drill sharpener, but I can sharpen drills by hand better than the piece of crap that is there
09:03 PM weenerdog: howdy howdy
09:07 PM weenerdog: howdy skunk, inforno
09:18 PM tiwake: anybody else use darex drill sharpeners before?
09:20 PM weenerdog: i have not
09:24 PM miss0r2: hehe, its fun to see what people are in here at this hour :) Not people i would normally see in my "daytime hours"
09:26 PM cncnoob: Howdy. I've never run a lathe before, but wanted to get one that I could grow into. I would perform a CNC conversion on it right when I got it. I read a lot of good things about South Bend lathes, and also see there are some conversion kits out there if I decide not to make my own. Any thoughts on what to watch out for, or what price to expect?
09:26 PM cncnoob: I was looking at this one, but it seems like the price might be a bit high:
09:26 PM cncnoob: https://kansascity.craigslist.org/tls/d/kansas-city-south-bend-13-5-metal-lathe/6834392856.html
09:44 PM skunkworks: cncnoob: not this one? https://kansascity.craigslist.org/tls/d/mori-seiki-cnc-lathe/6817416472.html
09:45 PM cncnoob: That is a bit big
09:46 PM cncnoob: also not a south bend, which is what I've been doing all my research on thus far
09:46 PM cncnoob: If there is a better option for a CNC conversion I'm open to suggestions.
09:46 PM weenerdog: research shmesearch :)
09:46 PM jdh: already cnc is better than convert to cnc
09:47 PM cncnoob: Humm, I guess
09:47 PM cncnoob: Good thing about doing conversions yourself is that you learn about the machine in the process
09:48 PM jdh: you could probably sell the control or parts for the cost of the lathe
09:49 PM tiwake: cncnoob: just see if the ways are good is the main thing, if you are getting a used machine
09:50 PM weenerdog: i got a stupid question i cant find an answer for... when you order cheap ass ballscrews, is the length just the threaded part, or the whole thing?
09:50 PM tiwake: honestly you can get a CNC machine for really cheap, a lot of times for the same price of a manual.. sometimes cheaper
09:52 PM tiwake: I think we bought the okuma CNC lathe for $5,000
09:52 PM tiwake: weighed 10k lbs
09:53 PM tiwake: might have been less
09:53 PM tiwake: like $3,000
09:53 PM tiwake: I don't exactly recall
09:53 PM tiwake: good machine
09:54 PM tiwake: I bought a hardinge CHNC lathe for $500
09:54 PM tiwake: that one needs a controller built for it though
09:55 PM tiwake: going to be building my first linuxCNC controller finally... probably going to start on that sometime this summer
10:23 PM cncnoob: A lot of the machines that can be had at a decent price are huge
10:24 PM cncnoob: I'll be putting the machine in question in my 3 car garage
10:24 PM cncnoob: I don't have room for something that weighs 10k lbs :)
10:42 PM Elmo40: or the electrical supply!
10:43 PM Elmo40: who has 3-phase in their house? ;-)
11:37 PM miss0r2: Elmo40: Everyone? :)
11:37 PM miss0r2: 'round here anyway
11:44 PM Elmo40: damn europeans...
11:44 PM Elmo40: i wish north america went on the 220V setup in the beginning.
11:45 PM Elmo40: 110V is such a drain. High currents for no reason.
11:58 PM miss0r2: indeed :]
