12:35 AM Wolf_: I like my big ass wilton horizontal bandsaw, was like $150 at a auction
12:39 AM codepython7771: Wolf_: the new ones are $3k+!
12:39 AM Wolf_: not so easy to move though, but really nice for cutting heavy stuff, but the go to the shop is usually the porta-bands
12:49 AM codepython7771: Wolf_: am thinking of getting a grizzly
12:50 AM Wolf_: shouldn’t be bad for infrequent use, if I was running it daily I would try to find a used wilton or something of the sort
12:51 AM Wolf_: check bidspotter or something like that
12:56 AM IchGucksLive: morning from germany
01:01 AM codepython7771: https://www.amazon.com/dp/B016VD8GAA/?tag=bandsawbrand-20 - an interesting machine at a good price
01:02 AM archivist: crap compared to chop saw with a metal blade
01:02 AM archivist: slower, cuts not straight
01:04 AM codepython7771: archivist: when does one move from chop saw to a horizontal band saw? better cuts?
01:05 AM Wolf_: cost per cut on heavy steel
01:05 AM archivist: the horizontal band saws a very solid to get a straight cut
01:05 AM Wolf_: plus that ^
01:06 AM archivist: I use a chop saw for simple stuff and a slitting saw on the horizontal mill for bigger stuff
01:06 AM codepython7771: I am looking to cut alum c-channels and steel rods upto 1/2in in diameter once a month - max 50 cuts.
01:07 AM codepython7771: I can buy a nice dewalt chow saw in my budget easy (< $300) - horizontal band saws seem to be expensive - at least the good ones.
01:08 AM Wolf_: my horizontal gets fed 2”x4”x1/4” tube, 1.5” rod stock, 1.5”x3” heavy C channel often, usually 20-30 cuts per session
01:08 AM codepython7771: it does seem like horizontal band saws do better quality cuts though
01:08 AM Wolf_: light alum I
01:09 AM Wolf_: ‘ll cut with my miter saw
01:10 AM codepython7771: http://www.grizzly.com/catalog/2017/main/677?p=677 - any thoughts on the top one? It's in my budget
01:11 AM archivist: also consider buying cut to size, the sellers have cnc band saws
01:11 AM codepython7771: the bottom one on that page has a smaller motor and a bigger price?
01:11 AM * XXCoder facepalms
01:12 AM XXCoder: person says oxygen was invented in 1700s lol
01:13 AM archivist: codepython777, I go to the local steel stockist with a cutting list all just gets done for you
01:13 AM Wolf_: ^ I love that, but most of mine will only do that on full stick orders
01:13 AM Wolf_: like 40 feet of tube
01:15 AM LeelooMinai: Ok, got windows 10 working in VirtualBox inside Debian 8 and talking to serial modem by USB and by RF to the Chinese microinverter.
01:17 AM LeelooMinai: http://i.imgur.com/5jAQZNa.png
01:17 AM LeelooMinai: Unfortunatelly it's night, but whatever - tomorrow I will solar:)
01:18 AM archivist: Wolf_, those that supply machine shops dont mind the order size it seems
01:18 AM archivist: expecting a slice off a 6" aluminium bar
01:20 AM Wolf_: well, that was the case for the one supplier I dealt with, but they did just structural steel, and there was a price break for full sticks of stuff, but no cut fee either
01:22 AM Wolf_: when I was picking stuff up from metal express I would just go there and ask to look through the drop stack/shelf
01:22 AM Wolf_: which they would sell me at scrap price
01:23 AM Wolf_: usually left there with 3x more then I needed for 1/2 the price they would have charged me for the short cut pieces I needed
01:24 AM archivist: I went to an alloy place last week but their offcuts seem gold plated prices, so just got the angle I wanted
01:34 AM Crom: yay receive my 55mm and 30mm M5 allen cap 12.9 screws
02:20 AM LeelooMinai: lol @ Trump's tweet: "Putin & I discussed forming an impenetrable Cyber Security unit so that election hacking, & many other negative things, will be guarded.."
02:21 AM Wolf_: master of trolling the media…
02:24 AM LeelooMinai: Wolf_: That's like saying that a guy that died in a car crash was mater of trolling the speed limits:p
02:25 AM LeelooMinai: Seems even GOP senators couldn't stop making jokes about it.
02:34 AM Wolf_: most senators are so far out of touch with real life its not even funny
02:34 AM LeelooMinai: I don't see a relation to the story:)
02:35 AM LeelooMinai: I am not sure now which idea was more stupid: solar poanels on the wall of USA-Russia Cyber Sercurity Unit:)
02:35 AM Wolf_: I don’t see the speed limit thing…
02:36 AM LeelooMinai: Wolf_: The point was that saying stupid and self-destructive things is not exactly "trolling".
02:37 AM LeelooMinai: It's just, well, saying stupid things.
02:37 AM Wolf_: he picks his words, discussed doesn’t mean forming a KGB office in DC
02:37 AM Deejay: moin
02:39 AM Wolf_: with that tweet there is probably loads of people who believe the DNC hacking BS heads exploding
02:40 AM LeelooMinai: Wolf_: He doesn't pick anything imo, just randomly produces absurd statements, and then has to correct them, or someone else has to correct them, or just laugh at them, even from his party - it's not helping him in anything.
02:42 AM LeelooMinai: And people slowly learn not to take him seriously. At the G20 meeting they basically treated him like some mentally-chalenged clown:)
03:01 AM XXCoder: yes, guard the hacking and many negative things!
03:01 AM XXCoder: LeelooMinai: did you see where he sits? way off to end, if it was 4:3 picture he would be outside it
03:06 AM XXCoder: ikea drill. https://www.youtube.com/watch?v=s4RPN7WM4gI
03:10 AM XXCoder: "its great but don't let your buddy see it"
03:10 AM XXCoder: lol
05:39 AM jthornton: morning
05:41 AM XXCoder: wb
05:42 AM Loetmichel: hmpf... someone any idea how to glue that back together that can withstand 350++°C? thats about the tenth time it breaks on me... couldnt they have used a more heat resitant plastic? -> http://www.cyrom.org/palbum/main.php?g2_itemId=16731&g2_imageViewsIndex=1
05:43 AM XXCoder: lathe and alum rod section. :)
05:44 AM Loetmichel: XXCoder: bad idea, then the thread on the handle will melt
05:44 AM Loetmichel: it has to be something that will NOT conduct heat well
05:44 AM XXCoder: hmm yeah makes sense
05:47 AM XXCoder: wood?
05:47 AM DaViruz: get a spare nut?
05:47 AM Loetmichel: XXCoder: thats actually not a bad idea... just have to find one that will retain the smallish tread...
06:04 AM * Loetmichel just tried a bit of "epoxy aliminium putty"... lets see how that works with the soldering iron set to 570F
07:02 AM justan0theruser is now known as justanotheruser
07:31 AM pink_vampire: Loetmichel: threadmill phenolic resin or bakelite
07:31 AM XXCoder: yo
07:32 AM XXCoder: good morning heh
07:32 AM pink_vampire: good morning XXCoder :)
08:00 AM Loetmichel: hmm, seems to work well: http://www.cyrom.org/palbum/main.php?g2_itemId=16734&g2_imageViewsIndex=1 ... lets see how long ;)
08:00 AM pink_vampire: wtf is that O_O
08:01 AM Loetmichel: the reassembled soldering iron with some epoxy putty over the offending part ;)
10:03 AM Tom_itx: looks like a weller iron
11:44 AM Loetmichel: *niiice* I just got a phonecall from the mechanic that usually works on my BMW... "i just noticed that your Opel Omega that you parked here when you took the BMW last time isnt locked... is that intentional or shall i lock it now?" ... of course it wasnt intentional.. but nice to know that my mechanic can remember which "beater cars" his customer drive AND took the courtesy to call.
11:46 AM Loetmichel: Tom_itx: its a chinese brand. the model is called "ZD-917". if you google it you will find the station and the spare parts...
11:46 AM Loetmichel: sadly: the ring isnt aviable as a spare
11:46 AM Loetmichel: only the complete iron
11:58 AM IchGucksLive: hi from germany
12:00 PM IchGucksLive: servus boddenkreuzer und was macht der speed
12:00 PM boddenkreuzer: naja, bei 5,5m/min blieb die Kiste stehen. Fehlermeldung war irgendwas mit ferror
12:01 PM boddenkreuzer: should we change to english?!
12:01 PM boddenkreuzer: I downgraded today to 2.7.9
12:01 PM boddenkreuzer: may I past my ini to pastebin?
12:03 PM boddenkreuzer: I just pasted my "new" ini to pastebin: https://pastebin.com/6jbPJmDV
12:04 PM boddenkreuzer: If someone could help me to get my machine a bit faster?
12:04 PM boddenkreuzer: When I tried to change some values today, I got an error like "ferror..."
12:05 PM IchGucksLive: MAX_LINEAR_VELOCITY = 25.000000 you said 5.5m thats way beond that
12:05 PM IchGucksLive: i expected 100
12:05 PM IchGucksLive: line 25
12:08 PM IchGucksLive: the display value shoudt be the same as the TRAY
12:08 PM IchGucksLive: line 75 MAX_LINEAR_VELOCITY = 200.00
12:08 PM boddenkreuzer: ok I just changed MAX_LINEAR_VELOCITY to 100
12:08 PM boddenkreuzer: but the machine stops after half a meter with joint 1 following error
12:09 PM IchGucksLive: joint1 is Y
12:10 PM IchGucksLive: boddenkreuzer: what Stepepr drivers are mounteddriver
12:10 PM IchGucksLive: STEPLEN = 2500 may increase a bit to 3500
12:11 PM IchGucksLive: Question to boddenkreuzer arednd there homeswitches
12:11 PM boddenkreuzer: no, not yet
12:11 PM IchGucksLive: Homeoffset shoudent be the samw value as Home
12:12 PM IchGucksLive: Homeofset is in most cases zero but home shoudt move the mashine aeay from switch like HOME=5 in XY and HOME = -5 in Z
12:13 PM boddenkreuzer: I just changed Steplen for the Y-Axis and it stops again with "joint 1 following erroe"
12:13 PM IchGucksLive: stepspace needs also to be changed
12:13 PM boddenkreuzer: to?
12:14 PM IchGucksLive: 3500
12:14 PM IchGucksLive: ise this value for all axis
12:14 PM IchGucksLive: reduce the ACC on Y to 400
12:15 PM IchGucksLive: and VEL to 120
12:17 PM IchGucksLive: what is the main use of your gantry as 0,05 precicion
12:19 PM boddenkreuzer: I changed ACC to 400 and VEL to 120. So the max speed I can choose is 7200mm/min. If I do so, it stops after 200mm with the same error
12:21 PM boddenkreuzer: with 4100 mm/min the Y axis runs the whole way of 2580 mm without any error
12:21 PM boddenkreuzer: is this a problem of the mx4660?
12:21 PM IchGucksLive: no
12:21 PM IchGucksLive: its timing
12:22 PM boddenkreuzer: time consuming..
12:22 PM IchGucksLive: so lets go for 5000 5000 8000 10000
12:22 PM IchGucksLive: steplen stepspace
12:22 PM IchGucksLive: dirsetup dirhold
12:23 PM IchGucksLive: hi MrBismuth
12:23 PM boddenkreuzer: Changed it for Y? the others to?
12:24 PM IchGucksLive: does X run in 2500 the full speed
12:25 PM phipli: evening
12:25 PM IchGucksLive: ;-)
12:26 PM IchGucksLive: its getting dark outside thunder in the far
12:26 PM boddenkreuzer: I can choose 7200mm/min for X and it run the whole 1200mm. But I dont have a feeling for that speed.
12:26 PM IchGucksLive: you see it in the Display what does VEL say
12:26 PM IchGucksLive: 7200
12:27 PM boddenkreuzer: it says 7200
12:27 PM boddenkreuzer: did I mention that I have two motors at the y axis?
12:27 PM IchGucksLive: that is the next guess
12:28 PM IchGucksLive: how did you connect the signals
12:28 PM IchGucksLive: the MX4 has 4 Drivers intern
12:28 PM boddenkreuzer: the 4 motors have a driver each
12:28 PM IchGucksLive: so did You use 123 for the XYZ and hook up the 4th to the second Y
12:28 PM boddenkreuzer: yes
12:29 PM boddenkreuzer: I did that in the pnc conf. it was called something like "tandem"
12:29 PM IchGucksLive: ok so lets see the HAL please
12:29 PM IchGucksLive: pcw_home:
12:29 PM IchGucksLive: he got a 5i25 pure
12:29 PM IchGucksLive: non addon card
12:30 PM IchGucksLive: i only use the 7i76 version so may be trouble on this side
12:30 PM boddenkreuzer: here is my hal file: https://pastebin.com/Pi274xys
12:33 PM IchGucksLive: boddenkreuzer: setp pid.y.maxerror .0005
12:33 PM IchGucksLive: that is the problem
12:34 PM boddenkreuzer: what does that mean?
12:34 PM IchGucksLive: its to low
12:34 PM IchGucksLive: the follow error is triggerd to early
12:34 PM boddenkreuzer: set it to ?
12:35 PM IchGucksLive: 0.1
12:35 PM boddenkreuzer: only for Y?
12:36 PM IchGucksLive: lets test this first THERE is also onl ine 146
12:36 PM IchGucksLive: setp hm2_5i25.0.stepgen.03.control-type 0
12:36 PM IchGucksLive: shoudt be 1
12:37 PM IchGucksLive: boddenkreuzer: Q: did you invert the DIR signal from the second Yotor
12:38 PM IchGucksLive: Y Stepper
12:38 PM boddenkreuzer: yes, in the pnc conf. And I tested it in reals life, it works
12:38 PM IchGucksLive: WHY dident you change the Wire
12:38 PM boddenkreuzer: I dont know
12:39 PM IchGucksLive: it is best comen to not do drive same Axis gantry with diferend dirs
12:39 PM IchGucksLive: you need to switch the Phases internel not the left pair to the Right
12:39 PM IchGucksLive: so from A+A- to A-A+
12:40 PM boddenkreuzer: do you know an editor under debian with line numbers?
12:41 PM IchGucksLive: gedit
12:42 PM IchGucksLive: under VIEW make a hok to Linenumbers= Zeilennummern
12:42 PM boddenkreuzer: i got one, mousepad
12:42 PM IchGucksLive: also line 151
12:42 PM IchGucksLive: net y2-pos-fb <= hm2_5i25.0.stepgen.03.position-fb
12:42 PM IchGucksLive: you can eleminate this line by # as first sign
12:44 PM boddenkreuzer: done, may I post it again at pastebin, just to be sure to got all your changes?
12:45 PM IchGucksLive: no no need
12:45 PM IchGucksLive: test the mashine
12:47 PM boddenkreuzer: something went wrong. it seems the two motors at Y move in the same direktion, so for moving in opposite
12:49 PM IchGucksLive: as i said you need to change the wire when you do a HAL pinswap
12:49 PM boddenkreuzer: thats not that simple at the moment. its all "well" wired
12:50 PM IchGucksLive: boddenkreuzer: du musst wenn due den setp hm2_5i25.0.gpio.012.invert_output true rausnimmst auch die kabel drehen
12:50 PM boddenkreuzer: das kann ich nicht so einfach
12:50 PM IchGucksLive: ok then leave the setp hm2_5i25.0.gpio.012.invert_output true
12:52 PM boddenkreuzer: das steht auf true
12:52 PM boddenkreuzer: setp hm2_5i25.0.gpio.012.invert_output true
12:54 PM IchGucksLive: so then we need also to change back the control type at line 146
12:54 PM IchGucksLive: setp hm2_5i25.0.stepgen.03.control-type 0
12:56 PM IchGucksLive: according to http://www.linuxcnc.org/docs/html/drivers/hostmot2.html#_parameters_3
12:56 PM IchGucksLive: it shoudt be Zero
12:56 PM boddenkreuzer: done
12:56 PM boddenkreuzer: Y runs with 6m/min
12:56 PM IchGucksLive: why is line 124
12:56 PM boddenkreuzer: without error
12:57 PM IchGucksLive: good
12:57 PM IchGucksLive: try aslso 7200
12:57 PM IchGucksLive: the 5i25 shoudt reatch 12m 12000 by default
12:58 PM IchGucksLive: as the mx4600 can go for 2500 2500 5000 8000
12:58 PM boddenkreuzer: works! I mean 7200
12:58 PM IchGucksLive: if this is what you expect we are done here SMILE
12:59 PM boddenkreuzer: nicht ganz... Bekommen wir die Kiste noch auf 10m/min? bitte?!
12:59 PM IchGucksLive: erhöhe doch einfach die werte
01:00 PM IchGucksLive: ini VEL 170
01:00 PM boddenkreuzer: in the display area and the Axis area in the ini file?
01:00 PM IchGucksLive: yes
01:01 PM IchGucksLive: dont forget the MAX_stepgen_VEL to 200
01:03 PM IchGucksLive: boddenkreuzer: why are the Z at 400steps per mm
01:03 PM IchGucksLive: wasting time speed and torque
01:03 PM IchGucksLive: is the Driver to the mx4660 at Z set to more then halfsteps
01:04 PM boddenkreuzer: Y works with 10m/min, but X stops with an "joint 0 following error"
01:05 PM boddenkreuzer: Great so far! It is great to sit next to the machine moving...
01:05 PM IchGucksLive: then you know where to go
01:05 PM IchGucksLive: line 56
01:05 PM boddenkreuzer: Thats the .0005 for X to .1?
01:05 PM IchGucksLive: yes
01:06 PM IchGucksLive: and if you can go use also ACC 400 on X
01:06 PM IchGucksLive: in the ini
01:07 PM boddenkreuzer: done! works! Thanks a lot!
01:07 PM IchGucksLive: BUT as i said please do a Wirer change to the Y2
01:08 PM boddenkreuzer: I will do it tomorrow, sure!
01:08 PM boddenkreuzer: would you mind if I come back tomorrow for some other questions about homing and switches and offsets?
01:09 PM boddenkreuzer: do you know how to copy the chat window? I would like to have it to my "akten"
01:10 PM IchGucksLive: NP we are here Dayout
01:10 PM IchGucksLive: boddenkreuzer: follow the link
01:11 PM IchGucksLive: boddenkreuzer: got it
01:11 PM boddenkreuzer: yes. thanks
01:12 PM IchGucksLive: boddenkreuzer: get rid of the 400 scale on the Z also
01:12 PM IchGucksLive: what is the Hardware used on the Z axis
01:12 PM boddenkreuzer: trapezgewindespindel 1605
01:12 PM boddenkreuzer: Hub 200mm
01:13 PM IchGucksLive: that gives a 5mm pitch
01:13 PM IchGucksLive: is there a gear
01:13 PM boddenkreuzer: no
01:13 PM IchGucksLive: like on rackpinion XY
01:13 PM IchGucksLive: so direct stepper mount
01:14 PM boddenkreuzer: yes
01:14 PM IchGucksLive: then use DIP switches to set 400steps
01:14 PM IchGucksLive: to the Z driver
01:14 PM boddenkreuzer: ok
01:15 PM IchGucksLive: 400/5 =80steps per mm
01:15 PM IchGucksLive: in the ini STEP_Scale
01:15 PM IchGucksLive: at the Z axis
01:16 PM IchGucksLive: then you can run the Z at 3000mm/min
01:16 PM IchGucksLive: thats VEL 50 and ACC 120
01:17 PM IchGucksLive: dont forget the STEPGEN numbers to 75 and 170
01:17 PM IchGucksLive: trhen you got the hell of a speed mill
01:17 PM boddenkreuzer: that sounds great and was the plan!
01:18 PM IchGucksLive: https://www.youtube.com/watch?v=sqx9w80diKo
01:18 PM boddenkreuzer: IchGucksLive: muss ich mir Sorgen machen dass wir beide die einzigen sind die reden?
01:18 PM IchGucksLive: nein
01:19 PM IchGucksLive: die nadern hören zu und copieren
01:19 PM boddenkreuzer: na dann
01:19 PM Loetmichel: und lesen mit um evtl zu korrigieren... aber hier is eigentlich englisch.
01:20 PM boddenkreuzer: the 4th axis is the next project. after getting the first three axis running...
01:21 PM IchGucksLive: boddenkreuzer: the MX4660 will make a full 5 axis
01:21 PM IchGucksLive: even gantry
01:21 PM boddenkreuzer: thats for next year. I started the construction already
01:21 PM IchGucksLive: BUT best is to go for a second BOB
01:22 PM IchGucksLive: and a DQ524
01:22 PM IchGucksLive: this gives you the same speed as the MX
01:22 PM boddenkreuzer: the main reason for the mx was cncrouterparts
01:22 PM IchGucksLive: if you can pay for a DM556 go for it
01:23 PM IchGucksLive: the 8EURO TB6600 will run out at 6000
01:23 PM IchGucksLive: but its also the max 90% of us need
01:23 PM boddenkreuzer: the next mill will have servo
01:23 PM IchGucksLive: so 8EU vs 60
01:24 PM IchGucksLive: boddenkreuzer: then go for the 7i77
01:25 PM boddenkreuzer: I have to leave now. Thanks a lot to IchGucksLive and all other here!
01:25 PM IchGucksLive: Gn8
01:26 PM boddenkreuzer: see you probably tomorrow
02:43 PM LeelooMinai: I don't like this guy - there's something south USA about him:p
02:43 PM LeelooMinai: I don't like this guy - there's something south USA about him:p
02:48 PM jdh: me?
02:53 PM LeelooMinai: I don't like this guy - there's something south USA about him:p
03:33 PM JT-Shop: only took 4 days to install the window unit in the new shop, now to plug the hole from the portable ac exhaust
03:44 PM jdh: cardboard and duct tape
03:46 PM JT-Shop: I certainly have plenty of that lol
04:38 PM * Loetmichel2 just had a call from an old friend. Didnt hear from him for about 10 years... "hey, loet, i have a slight problem... i want to move to a caribian island soon... alrady bought a big genset to have power there... 120kVA... its NOS from the german army. 20 years old but 0 hours. worsk perfectly mechanically, but the voltage regulator is dead. Also the rpm governor weaves 5hz... so i
04:38 PM * Loetmichel2 bought a new electronic governor and a regulator... can you fix that to such an old genset?" $me "of course. I'll be there next saturday at noon. Its only 400km to you and i already wanted to have an excuse to drive the BMW... have plenty supply of beer at hand and somethign to eat. nice evening of tinkering with old friends... what could be better?"
04:44 PM Deejay: gn8
05:22 PM Vitran: I am slightly closer to getting the lathe to work. After a bunch of fighting I got EMC2 back open. There are still nagging questions on what the machine does however. Still don't know what the spindle lock pin is
05:26 PM andypugh: As in, the HAL pin or the physical pin?
05:26 PM Vitran: It is a real thing
05:27 PM Vitran: I have a sensor and a coil both to detect if it is in or out and to drive it in and out
05:30 PM andypugh: That’s odd, for a lathe
05:30 PM andypugh: A brake is fairly common, a pin much less so.
05:30 PM Vitran: There is a break
05:30 PM Vitran: A spindle break
05:31 PM andypugh: Is the pin part of the toolchanger, that would be fairly common.
05:31 PM Vitran: http://i.imgur.com/YNjsaX3.png
05:33 PM Vitran: Here is the drawing. Spindle lock pin sensor is on the left and 'engage spindle lock pin' is a coil on the right
05:34 PM JT-Shop: yea my ER11 nut came in and nothing is wrong with the tool holder now'
05:35 PM Jymmm: WOOHOO
05:36 PM JT-Shop: so instead of a $120 mistoke it only cost me $20
05:36 PM skullworks: The RS-274D variant that LCNC uses still adhears to the single letter word address system. Other flavors such as used by FADAL, OKUMA and others allow multi letter word addressing. Such as BHC, LAA, XGRID etc.
05:37 PM skullworks: how big of a wrench would it throw into the interp to allow that?
05:39 PM andypugh: Apparently XX. YY ZZ AA are already allowed for and little trouble to add.
05:39 PM skullworks: Just an idea to address the multi spindle control question while opening many new functional options in the future.
05:39 PM andypugh: (according to a comment on IRC a few days ago)
05:43 PM skullworks: I used the Okuma codes extensively due to the 32K memory limit of the machine, I know the current in vogue method is to let your CAM spit out miles of top down chip thinning code...
05:45 PM Vitran: I got annother odd part of the hardinge superlsant machine I am working on. The wiring diagrams didn't seem to have a pin to turn on the hydraulics. The hydraulics is linked to some kind of solid state timer and I can't seem to track down if it is connected to the PLC. Could the hydraulics have some sort of 'auto' turn on thing?
05:45 PM Vitran: The hydraulics only seem to turn on the collet
05:49 PM skullworks: Was the XX YY etc. the product of work for gantry systems?
05:50 PM Vitran: Maybe for a hexapod platform? https://s-media-cache-ak0.pinimg.com/736x/23/51/c1/2351c176647fcc463cfe90542f1bdfd3.jpg
05:55 PM andypugh: Vitran: No, hexapods only use XYZABC. It’s the difference between joints and axes.
05:56 PM andypugh: And I have no idea why you would need a spindle lock pin on a CNC lathe.
05:56 PM skullworks: Hexapod seems like they would only be practical in big factory conditions. I would consider mounting a Puma Robot to the ceiling to act as a dedicated tool changer.
05:59 PM skullworks: I guess I'm old school, I would prefer a "traditional" 5 axis machine.
06:00 PM Vitran: Neighbour's brother needs help and is asking around if anyone knows how to get a 9 axis machine running
06:01 PM renesis: normal affordable hexpads do abc?
06:02 PM * skullworks can get a good Migrain just thinking about wiring up a 3 aixs with all the I/O and M function relays.
06:02 PM renesis: also im guessing unless your hexapod is the size of a truck, machine rigidity is a joke
06:04 PM skullworks: Well the killer to me is the floor space the complete machine requires for such a small base circle work area.
06:05 PM Jymmm: skullworks: I'm good with wiring pretty much anything. I used to have to with up control panels with a 100ft spool of all white wires =)
06:06 PM Jymmm: 1000*
06:07 PM skullworks: Jymmm - Know what a 66 block is?
06:18 PM Frank___: Hi everyone!
06:18 PM Jymmm: skullworks: and a 110 block too, and I have the punchdown tool for both =)
06:18 PM BeachBumPete: hey folks
06:19 PM Frank___: anyone knows an easy way to wire a 8-lead stepper motor to a 4 lead driveR?
06:19 PM Jymmm: cut 4 wires? lol
06:19 PM skullworks: Picture a grid of 240 blocks on 1 ft centers, 6 blocks tall
06:20 PM Frank___: im going to try that jymm
06:20 PM Frank___: :D
06:20 PM Frank___: thanks
06:20 PM Jymmm: Frank___: Better you than me =)
06:20 PM Frank___: :P
06:20 PM Vitran: Wiring an 8 as a 4? I did that for a few 3D printers when I was digging for motors. Is it not just this? http://www.piclist.com/images/member/RB-ezy-Q33/4WireSeriesParallel.png
06:20 PM Jymmm: skullworks: I didn't say I'd love it, just comes more naturaly to me.
06:21 PM Vitran: Do you want more steps or more torque?
06:21 PM Frank___: more torque
06:21 PM skullworks: actuall pair up the wires and run thein parallel, or use only half and run at half force.
06:21 PM Jymmm: MORE COW BELL!!!
06:23 PM Frank___: okey but which wires should i pair up? ill try to keep searching too
06:24 PM Vitran: Now that I think about it, both will work. It will matter more about how much current you can draw from your supply and the inductance/resistance of the coils. If your supply can produce more voltage, go series. More current, parallel
06:25 PM skullworks: I was offered the job of wiring all the incoming lines at the demark point and doing the cross connect to the site systems for the 84 Olympics Games in Los Angeles - I bid high ( going for the gold myself) and did not get the job.
06:26 PM Jymmm: skullworks: Eh, maybe it was a good thing you didn't.
06:27 PM skullworks: Some Poor girl who had been Laid off from AT&T took the job, bid it at 8 weeks + material. Took her 14 1/2 weeks to complete and pass all testing.
06:27 PM BeachBumPete: Go FOR THE GOLD MAN!!
06:29 PM skullworks: Not only that, she let them include a deal where she provided the wire as she went and would turn in receipts when the job was done for payment.
06:30 PM skullworks: Took like 4 pallet loads of single twisted pair jumper wire.
06:32 PM skullworks: I held out and got an even better gig on the lot (International Broadcast Center) installing the AT&T Horizon phone system and network - damn I do not miss the old BNC coax networks....
06:32 PM andypugh: Frank___: You can work out which way the wires pair up by touching them together in pairs and seeing which ones make the motor stiff to turn.
06:32 PM andypugh: That will give you 4 pairs.
06:33 PM skullworks: BBPete - Stock done?
06:34 PM andypugh: Then you can take one end of two pairs and connet them, and then connect the other end of the same two pairs. If that is stiff you have the pairs connected in series. That tells you the end polarities of each pair. If that isn’t stiff then either they are not both-A or both-B or you have them back-to-back.
06:34 PM andypugh: This is worth doing anyway. I had motors where the data sheet was wrong about the wire colours.
06:35 PM skullworks: Or worse - one winding is shorted and waiting to let the smoke out of the driver.
06:37 PM BeachBumPete: skullworks no its not unfortunately
06:37 PM BeachBumPete: I have it all programmed
06:38 PM BeachBumPete: but I decided that I want to run it with my router plate setup instead of the factory spindle
06:38 PM BeachBumPete: and I keep forgetting to bring my router home LOL
06:38 PM BeachBumPete: I also had lent the router to a friend who was working on his house for awhile
06:38 PM BeachBumPete: but I got it back now and was planning to bring it home tonight but forgot again hehe
06:39 PM BeachBumPete: I was planning on setting up the program to run entirely with a long length 1/4 inch high helix endmill
06:39 PM McBride36: i'm really enjoying this $13 tap and die set from HF. I don't think i've gotten so much frustration out of something so cheap
06:39 PM skullworks: I want to make a 4 axis rig to do stock work - but my CNC mill only has 24.6" on X.
06:39 PM BeachBumPete: mine is only 20 hehe
06:40 PM BeachBumPete: but it is 20x20x20
06:40 PM BeachBumPete: what kind of mill do you have?
06:40 PM skullworks: X24.6 Y13.5 Z5.14
06:41 PM skullworks: Hurco KM3 and a Hurco KM3P
06:41 PM BeachBumPete: oh thats right
06:42 PM skullworks: KM3P is down indefinately - mice ate much wiring, so I need to strip the parts off the KM3 which is getting the LCNC retrofit now.
06:43 PM BeachBumPete: that bites
06:43 PM skullworks: I just need to be confident I have a workable solution for the KM3
06:43 PM BeachBumPete: I have an issue with my Cinci starting tho which SUCKS ASS!!
06:44 PM BeachBumPete: the spindle bearings are starting to make noise occasionally upon warmup
06:44 PM BeachBumPete: trying to source some new ones for it now
06:44 PM skullworks: Does it use an air oil spindle bearing?
06:45 PM BeachBumPete: I THINK it is just a permanently lubricated spindle bearing setup but not entirely sure
06:45 PM BeachBumPete: honestly the guy I bought it from over two years ago now said he thought it would be needing bearings at some point soon
06:45 PM BeachBumPete: so this is not a surprise
06:46 PM BeachBumPete: I already had to put some new spindle motor bearings in it awhile back and it has run great since then
06:46 PM BeachBumPete: but I noticed the last couple times I warmed it up that it made kind of a funny bearing noise for the first little bit until it warmed up
06:46 PM BeachBumPete: I have made a good bit of cash with it and I am STILL making money with it so this was not unexpected
06:47 PM BeachBumPete: as I understand it the new bearings are somewhere in the 7-800 dollar range for the set
06:47 PM BeachBumPete: plus the spindle bearing grease which is not exactly cheap
06:48 PM skullworks: I ran this KM3 since 9 months after the shop bought it. So I know it was never abused and the 1 good crash it had was caused by a Hurco tech working on the machine and they fixed everything with all new parts.
06:48 PM BeachBumPete: sweet
06:48 PM BeachBumPete: similar story with this one
06:48 PM BeachBumPete: the guy I bought it from worked in the shop that originally bought it in Tennessee
06:49 PM BeachBumPete: he ran it for the most part himself
06:49 PM BeachBumPete: then the shop went in another direction and he left and offered to purchase the machine
06:49 PM skullworks: the memory board died in 2000 and the CRT's died in 2002 - but you could still power it up and jog...
06:49 PM BeachBumPete: he then ran it from his home shop for quite a few years until he bought a HUGE fadal
06:50 PM BeachBumPete: Well its Dinner tmie... BBL
06:50 PM skullworks: I want a 4020, after I build a new building.
06:50 PM skullworks: enjoy
06:50 PM BeachBumPete: this was a 5080 or something BIG
06:51 PM skullworks: 4020 is the largest that had a 220V single phase option built in at the factory
06:52 PM skullworks: but yeah - go big or stay home 6030
07:08 PM Frank___: andypugh: thanks for the advice andy, i have the manual with the color scheme, but as usual, it could be wrong, ill do that and ill keep reading too. thanks as usual!
07:08 PM Frank___: im FINALLY wiring everything up
07:09 PM Frank___: shit this took too long...
07:10 PM Frank___: thanks for the help all the way through
09:43 PM pink_vampire: someone here doing air blush?
09:47 PM pink_vampire: brush*
10:05 PM CaptHindsight: hands Jymmm a cowbell made entirely of white wire
10:06 PM CaptHindsight: thump thump thump
10:13 PM Inside: yo
10:13 PM Inside: Not really a #linux question, but more of a CNC question. What do you guys run?
10:13 PM Inside: (The CNC itself)
10:18 PM CaptHindsight: mills lathes printers
10:18 PM CaptHindsight: most people here either have a lathe or a mill, som ehave both
10:19 PM Inside: like a real one
10:19 PM Inside: or a home made one
10:20 PM CaptHindsight: https://imagebin.ca/v/2RuHAsYVLA7N
10:21 PM CaptHindsight: https://imagebin.ca/v/2TZ69LKPSZ6P
10:22 PM Inside: that's like a real one :D
10:22 PM Inside: and a baby one :D
10:22 PM CaptHindsight: https://www.youtube.com/watch?v=81uwBAuR96I
10:22 PM roycroft: some of us run our mouths too much
10:23 PM CaptHindsight: https://www.youtube.com/watch?v=qBQ7RSuRAls
10:23 PM Inside: Neat
10:23 PM Inside: I guess my question was if building off of Joe's CNC plans is something worthwhile
10:24 PM CaptHindsight: https://www.joescnc.com/
10:24 PM Inside: Yes, that one
10:25 PM CaptHindsight: looks like routers
10:25 PM Inside: ah yes
10:25 PM Inside: a CNC router, specifically
10:25 PM Inside: for wood
10:29 PM CaptHindsight: does it look easy enough to build by yourself?
10:30 PM CaptHindsight: https://www.joescnc.com/joe-s-cnc-shop/
10:30 PM Inside: it does
10:31 PM Inside: I have no doubt I could put it together, but I'm looking more for testimonials or comments before I plonk down $75 for a PDF
10:31 PM Inside: also, curious about the price - $600 for the gantry plates for starters..
10:32 PM CaptHindsight: you have to learn and start somewhere
10:32 PM CaptHindsight: I've seen far worse
10:32 PM Inside: hahaha
10:32 PM Inside: yes, but this is for work so I'd rather not burn a pile of money :)
10:32 PM Inside: (that's not mine)
10:32 PM renesis: gantries are pretty shit for anything except wood and thin aluminum
10:32 PM * skullworks would be glad to run anything he could get powered up at this point.
10:33 PM CaptHindsight: I build most from scratch
10:33 PM CaptHindsight: sometimes i start with a complete machine and rebuild it
10:33 PM CaptHindsight: even brand new machines
10:33 PM Inside: renesis: Looking to just route 4x8 sheets of 0.75" hardwood plywood
10:33 PM skullworks: I don't have a big enough foundry to do that.
10:35 PM renesis: i hope you mean inches
10:35 PM * skullworks has been cheating by using a 3D printer.
10:37 PM Inside: renesis: me? yes.
10:37 PM skullworks: Inside - you out to build a router?
10:38 PM Inside: yup
10:38 PM skullworks: need a short ballscrew/nut for your Z?
10:38 PM Inside: ermm
10:38 PM Inside: I don't know yet
10:39 PM skullworks: I has a spare - they shipped the wrong unit, so
10:39 PM skullworks: I have one with no intended purpose.
10:43 PM Inside: Hmm - internet is telling me $3500 for a Joe CNC
10:44 PM Inside: I can't picture where all the cost comes from?
10:44 PM renesis: inside: 4x8"?
10:44 PM Inside: renesis: there abouts
10:44 PM renesis: get a taig
10:44 PM skullworks: Inside - stupid question - but did you google that PDF?
10:44 PM renesis: ive had mine over 10 years
10:44 PM renesis: its a better machine now than when i got it
10:45 PM renesis: and itll machine blocks of aluminum, up to 3/8" straight shank tooling with the ER16 spindle, 1k to 10k spindle with 6 pulley steps
10:45 PM renesis: rigidity waaaaaay better than a gantry router
10:45 PM renesis: and youre up and running for under $2k
10:46 PM Inside: renesis: wait no, 4x8 feet
10:46 PM Inside: not inches
10:46 PM renesis: http://www.ebay.com/itm/Taig-gecko-cnc-mill-milling-machine-engraver-router-/151666655360
10:46 PM renesis: oh
10:47 PM renesis: yeah thats nuts man
10:47 PM renesis: thats huge for diy
10:47 PM Inside: Well
10:47 PM Inside: 3x5' is bare minimum
10:47 PM Inside: but most people jump from 2x4 to 4x8
10:47 PM renesis: still huge, at that scale id be like fuckit and go for the full sheet
10:47 PM Inside: that's what I figured ;)
10:47 PM Inside: this is just wood though
10:48 PM renesis: right
10:48 PM skullworks: 5x10 so you can finish route the edges in a single setup
10:49 PM Inside: why not just go 8 x16 and do two sheets at the same time?
10:49 PM skullworks: How much is your shop floor space worth?
10:50 PM Inside: I don't know man
10:50 PM Inside: work is all up in the air
10:50 PM Inside: owner was looking at getting a 100,000 sqft facility
10:50 PM Inside: (this cnc would be for prototyping only)
10:51 PM Inside: we're still working out of an office building so this is probably just going to sit in someone's garage
10:52 PM samsagaz: oh i read right now that cant be used linuxCNC trough USB, which hardward is recommended?
10:52 PM skullworks: My next "home built" will be a 5x5 plasma/laser (swappable heads) that has a pull out extension to allow for full sheets, it just will only be able to do half at a time.
10:53 PM skullworks: for simple stuff GRBL has made great improvements in the recent releases - and Fusion360 has some great POSTs for it.
10:54 PM skullworks: I just hate the idea that I would have to repost G-code to adjust cutter radius comp - since GRBL doesn't have any.
11:29 PM Jymmm: CaptHindsight: Awww, no awesomeness =(
11:37 PM roycroft: inside: if this is your first cnc experience, it might be wise to build a smaller machine so that you can get some experience and develop some skills in building and operating a cnc router
11:38 PM Inside: fair enough
11:38 PM CaptHindsight: 2 sheets, if you go that far just go for 4 x 4
11:38 PM roycroft: having no cnc experience and deciding to build a large-ish machine and put it service (even if just for prototyping) is rather ambitious
11:38 PM CaptHindsight: 36' x 20'
11:39 PM roycroft: the computer/control end can be used for a larger produciton machine later, with perhaps new drives and power supplies needed
11:39 PM roycroft: and you would gain some experience for a smaller initial cost
11:39 PM CaptHindsight: and if your making things with that many sheets I'd say laminate your own
11:40 PM CaptHindsight: your/you're
11:40 PM CaptHindsight: invest in some forest land
11:40 PM Inside: Hmmm
11:40 PM CaptHindsight: plant, grow, cut
11:41 PM roycroft: build something small
11:41 PM roycroft: make some engraved signs for the shop
11:41 PM roycroft: get the feel of cnc
11:41 PM Inside: I've built a one axis CNC test stand ;)
11:41 PM roycroft: then build your full sheet machine
11:41 PM CaptHindsight: toothpick lathe
11:42 PM roycroft: the other option would be to buy a turnkey machine with training
11:42 PM roycroft: and you're talking well into 5 figures for that
11:42 PM Inside: yeah
11:42 PM Inside: that's a little much
11:42 PM roycroft: it's cheaper to build a small machine and then scale up than to buy the turnkey machine
11:42 PM roycroft: assuming your employer is willing to give you the time to build/learn it
11:43 PM Inside: well
11:43 PM roycroft: and to be honest
11:43 PM CaptHindsight: is it possible for you to outsorce to China?
11:43 PM roycroft: i would not buy plans for a cnc machine
11:43 PM Inside: I think I could sell on a 2'x2'
11:43 PM roycroft: i would either buy a turnkey machine or design my own
11:43 PM Inside: hmmm
11:43 PM roycroft: i wish the folks who sell the plans luck
11:44 PM roycroft: but i'm not a fan of their business model
11:44 PM Inside: Looking for something expeditions here, like usual :)
11:44 PM roycroft: i just don't understand it, i guess
11:44 PM Inside: currently we have a guy using a hand held router and a plotter to make holes ^_^
11:44 PM roycroft: my perspective is that if you just buy a recipe/formula and follow it blindly your chances of success are not that great
11:45 PM roycroft: and if you take the time to learn why it was designed the way it was, you can design your own that likely fits your needs better than a generic recipe
11:45 PM Inside: true true
11:45 PM CaptHindsight: start somewhere
11:45 PM CaptHindsight: learn
11:45 PM CaptHindsight: come back and complain
11:46 PM roycroft: and that somewhere might be to buy a $400 machine off ebay and learn how to use it
11:46 PM roycroft: i've no idea, of course, what your business need is, or your timeframe
11:46 PM Inside: eh, we just need to route holes and slots in a piece of plywood to mount stuff into
11:47 PM Inside: essentially panels
11:47 PM CaptHindsight: Jymmm: did you take lesson to play the cowbell?
11:47 PM roycroft: but if you need to do something fairly quickly, then buying a $400 machine off ebay would afford you the opportunity to see hwo cnc routers work
11:47 PM roycroft: and see the design shortcomings of the $400 machine
11:47 PM Inside: we've got a 3D printer - it's essentially the same thing ;)
11:47 PM roycroft: so that when you scale up to the production size one you'llnot make those mistakes
11:47 PM CaptHindsight: Jymmm: we had it as part of our percussion classes
11:49 PM Jymmm: CaptHindsight: you had copper wire cowbells in class?
11:50 PM CaptHindsight: ours were cheap tin
11:51 PM CaptHindsight: we had real wooden sticks however
11:59 PM tiwake: CaptHindsight: how is it going?
