12:37 AM ve7it: Jymmm, ping
12:49 AM Jymmm: ve7it: pong
12:50 AM ve7it: hey... just building a new cpu with ssd.... trying to get all my apps running again... this one seems ok so far
12:51 AM Jymmm: very cool
12:51 AM ve7it: postfix/fetchmail is kicking my arse
12:52 AM Jymmm: haha, it does to eveyone I think, that's why I avoid SMTP if I can =)
12:54 AM ve7it: postfix on mint had a nice post install script that walked one through the setup.... on arch, no such luck... I have the old config files, but its not enough to get it running
12:58 AM ve7it: anyway... off to bed
01:02 AM CaptHindsight: Jymmm: root_window.tk.call ("wm", "","."," geometry 1200x600") worked in Wheezy
01:23 AM IchGucksLive: hi
01:24 AM XXCoder: hey once again
01:24 AM IchGucksLive: ;-)
01:32 AM IchGucksLive: off 2garden starting a nice sunshine date by harvasting tomatos ;-)
01:33 AM XXCoder: my bro's single tomoto plant is doing well
01:33 AM IchGucksLive: later
01:33 AM XXCoder: cant wait to see it grow tomotos
01:36 AM RyanS: has anyone built a cnc plasma here?
01:36 AM XXCoder: I think couple did. not me tho
01:40 AM RyanS: the mechanical side seems fairly straight forward. it's the control electronics that seem the challenge
01:44 AM RyanS: does linuxCNC require a lot of expertise to set up properly?
01:45 AM XXCoder: it does take a bunch of research
01:45 AM XXCoder: it took me a while
01:45 AM XXCoder: but its not too bad
01:46 AM XXCoder: now, if you want to do more specific and unusual hardware it takes bunch more work to configure it
01:49 AM RyanS: there is plenty of router and mill turnkey electronics packages around, but only one I can think of for plasma. i'm leaning towards that
01:51 AM XXCoder: whats your user case anyway
01:51 AM XXCoder: is it production work
01:51 AM XXCoder: or once a while one offs
01:57 AM RyanS: i would like to design and sell signs and the like, but also parts for my own projects like a belt grinder. definitely not productio.
01:59 AM RyanS: 4'x4'/ 1200x1200mm table, single phase plasma unit
01:59 AM XXCoder: cool
01:59 AM XXCoder: you could essentally build one, but while its much cheaper there i tradeoffs
01:59 AM XXCoder: like less reliability
02:02 AM XXCoder: production is much more concerned with realibility
02:03 AM RyanS: yeah. the mechanics usually has easily identifiable problems, electronics, especially the torch height control sounds difficult
02:03 AM XXCoder: you do not want sudden problems when at 200 parts out of 1000
02:05 AM RyanS: most people building tables go with CandCNC electronics which I believe now uses a custom linuxCNC install
02:05 AM RyanS: used to use mach3
02:07 AM XXCoder: be back gonna go get something to eat
02:07 AM archivist: mach is losing ground for specials like plasma
02:16 AM Deejay: moin
02:33 AM XXCoder: hey LeelooMinai
03:09 AM XXCoder: https://www.youtube.com/watch?v=qMrlyEreba8 pretty cool
05:22 AM jthornton: morning
05:23 AM XXCoder: yo
06:29 AM Tom_L: hello
06:31 AM jthornton: morning
06:41 AM XXCoder: heys
07:22 AM Vq: heya
07:50 AM phipli: afternoon
07:51 AM phipli: how is everyone this sunny day?
07:51 AM jthornton: just fixing to hit the shower and start my day a bit late playing with the ardweenie
07:53 AM phipli: making the lamp controller?
07:53 AM jthornton: aye
07:54 AM phipli: this might be interesting to you : https://www.arduino.cc/en/Reference/PortManipulation
07:55 AM phipli: if you're doing really complicated things with outputs (perhaps not this project)
07:55 AM phipli: you can directly write bytes to a "port"
07:55 AM phipli: the Uno has 3 ports I think, although not all of every one goes to an output
07:55 AM phipli: heh
07:56 AM phipli: a while ago I loaded up an old program I wrote and tried to stick it in an Uno...
07:56 AM phipli: it failed, and I was confused why
07:56 AM phipli: until I spotted that I was using digital pin 28 or something...
07:57 AM phipli: suddenly realised that I'd written it for one of those huge DIP AVRs with loads of pins
07:57 AM phipli: these things are great : http://www.microchip.com/wwwproducts/en/ATmega1284p
08:06 AM jthornton: well I managed to set the time from the PC time and date so I'm off to start my day
09:07 AM JT-Shop: phipli: new record this morning 6 chicks on my arms at once :)
09:15 AM MarcelineVQ: you player you
09:54 AM DaPapa: hey guys
09:54 AM DaPapa: anyone available to offer some advice on stepper drivers
09:55 AM DaPapa: ive been here before and i was greatful for the help getting my first prototype cnc machine up and running, now i want to make one a little better
09:56 AM DaPapa: the current machine uses an integrated 3 axis tb6560.
09:56 AM cradek: I always hear that geckos are the least trouble
09:56 AM DaPapa: for my next machine i want to use nema 23.
09:56 AM DaPapa: gekos are a little too pricy sadly
09:57 AM DaPapa: im currently looking a dm542 drivers
09:57 AM cradek: yeah they are a lot more expensive than the imported single-boards
09:57 AM DaPapa: ive heard good things. any one have any experience?
10:06 AM phipli: JT-Shop: been spoiling ours with apples today
10:06 AM phipli: we have an apple tree but bugs have had a go at some of them
10:06 AM phipli: the birds were eating the windfalls anyway
10:07 AM phipli: DaPapa: No experience with those sorry - bit quiet here today
10:07 AM phipli: usually a bit more activity in a few hours time
10:09 AM hazzy: DaPapa: It might be worth looking into using 3ph closed loop steppers
10:09 AM hazzy: They don't cost all that much more and are far superior in my experience
10:09 AM hazzy: http://www.ebay.com/itm/NEMA23-3N-m-3phase-easy-servo-Closed-loop-stepper-motor-drive-kit-CNC-DC20-50V-/172690310642?epid=905996634&hash=item28352505f2:g:HAAAAOSwGJlZI9rx
10:14 AM MarcelineVQ: though not nearly as cheap as sticking your own encoder on there
10:17 AM hazzy: That is true, but that would not be equivalent
10:17 AM hazzy: Those steppers drives are not constant current, but very the current based on the following error
10:18 AM hazzy: That would be very difficult to reproduce with LCNC and standard stepper drives
10:32 AM -!- #linuxcnc mode set to +v by ChanServ
10:34 AM gloops_: well, my humble cycle chain drive cnc whips through mdf at half in cut pretty well, just need a day or two to get my head round a few things but all in all, i think im away
10:34 AM gloops_: (or got away with it haha)
10:34 AM SpeedEvil: :)
10:35 AM phipli: gloops_: what kind of feed rates are you managing?
10:35 AM phipli: (also congratulations :) )
10:35 AM gloops_: rough estimate about 200 ipm
10:36 AM gloops_: its not finished yet by a good way, wires everywhere, this needs squaring up that needs tensioning etc, i just wanted to see it cut so i knew i hadnt wasted my time
10:37 AM gloops_: no sorry - 200 rapids, feed is about 100
10:45 AM hazzy: gloops_: Very good! I'd love to see what your setup is. Can we have a pic?
10:45 AM gloops: lol, ill post some another time, it isnt really photogenic atm
10:46 AM hazzy: Were all family here :P
10:47 AM hazzy: Im thinking of a plasma table with chain drive
10:48 AM gloops: 424 oz nema 23s, 3-1 reduction - these are cycle sprockets welded onto bearings i made, an endless chain on the Y with the carriage attacked, X is single strand chain, again 3-1 reducer, bed atm is a timber frame with decking boards - which i will skim off
10:48 AM gloops: 425oz
10:50 AM gloops: it probably is more like a small plasma build than a router, no shiny ally extrusions or anything lol
10:50 AM gloops: biggest concern was backlash in the chain - that hasnt materialised at all
10:52 AM gloops: first vid next week, i got a couple of days off this week to finish it off and cut something nice on it
10:53 AM hazzy: So regular bicycle chain? I was thinking about maybe using #25 so it would move over the sprockets more smoothly, but I guess that is not needed
10:53 AM hazzy: What did you use for linear ways?
10:53 AM gloops: yeah 12.7mm pitch chain, also inside size is about 4mm , tbh a small pitch 7mm chain would be better
10:55 AM gloops: linear rails are some 2.5 inch tubes i had laying around, cut a larger tube to fit over like a sleeve with 20mm clearance, put 4 bearings on either end - like a roller coaster
10:56 AM gloops: primitive but the bed is only about 1mm out at any point over 4x2 feet
10:59 AM hazzy2: simple is better! Especially for wood working machines
11:02 AM hazzy2 is now known as hazzy
11:02 AM gloops: well it is my first ever go at cnc, i was more interested in learning than making a state of the art thing, with fingers crossed i would end up with a useable machine, i wont be making anything for anyones specs so a touch out here and there doesnt bother me
11:03 AM gloops: i have got some jobs for it though, hopefully it will pay for its replacement lol, ill probably go with ballscrews next time
11:44 AM Loetmichel: *hmm*.. i am definetly not 20 any more... one night without sleep (wife had the snore from hell) and a 9 hr work day and i am really at the end of my energy... .oo00°°
11:52 AM Deejay: ya need moar coffee ;)
11:53 AM Loetmichel: already had about 8 mugs today.. i think that'll be sufficient ;)
12:24 PM IchGucksLive: hi
12:25 PM IchGucksLive: hazzy: are you building a new front end
12:27 PM hazzy: Yes, trying to!
12:28 PM IchGucksLive: on vtk you may get a boolean operation onto vismach
12:28 PM IchGucksLive: so a real cat sim woudt be a great benefit
12:29 PM hazzy: Is vismach based on VTK?
12:29 PM IchGucksLive: no
12:30 PM hazzy: What do you mean 'on vtk you may get a boolean operation onto vismach'?
12:30 PM IchGucksLive: OpenGLTk, Tkinter minigl
12:30 PM hazzy: That is what I though, but I have not looked at it
12:30 PM hazzy: Same as Gremlin I guess
12:31 PM IchGucksLive: vtk is able to performe a Block cut
12:31 PM IchGucksLive: as GL isent
12:31 PM IchGucksLive: hazzy: try locate vismach.py on your test pc
12:31 PM hazzy: Oh, so you are thinking a solid model sim in backplot
12:32 PM hazzy: ok
12:32 PM IchGucksLive: the model sim is not the problem
12:32 PM IchGucksLive: that works perfect but it cand cut the part in soim mode
12:33 PM IchGucksLive: open a simulation mashine from the dropdown menue that says sim.vismach
12:33 PM IchGucksLive: andyou see
12:35 PM hazzy: Ok, I have vismach running
12:35 PM hazzy: It is better than I remember :D
12:36 PM IchGucksLive: what view do yoou got
12:36 PM IchGucksLive: puma ?
12:38 PM IchGucksLive: hazzy: http://pasteall.org/pic/index.php?id=118315
12:38 PM IchGucksLive: a 5 axis sim mashine
12:50 PM IchGucksLive: DaPapa: are you still here
12:53 PM DaPapa: hey sorry i was afk for a bit there
12:53 PM hazzy: IchGucksLive: Ive got the 5axis
12:53 PM IchGucksLive: what are y building as you go for the 542
12:54 PM DaPapa: initially a 3 axis cnc machine router
12:54 PM IchGucksLive: DaPapa: http://heimwerkermarkt-tretter.de/5achs_elek
12:54 PM IchGucksLive: http://heimwerkermarkt-tretter.de/3achs_elek
12:54 PM DaPapa: that looks like the kit i have been looking at
12:54 PM IchGucksLive: DaPapa: what size do you expect
12:55 PM DaPapa: 1000mm x 600mm x 150mm
12:55 PM IchGucksLive: Z170 is comen
12:55 PM DaPapa: my current tb6560 system is similar in size and works pretty well
12:55 PM IchGucksLive: http://heimwerkermarkt-tretter.de/holzcnc.jpg
12:56 PM IchGucksLive: this mashine is build wit only a drill
12:56 PM IchGucksLive: no mashineing of parts
12:56 PM DaPapa: the first cnc machine i built was from scrap mdf mosdly and meccano :P
12:56 PM IchGucksLive: so you know what to do
12:57 PM DaPapa: the new one will be made from steel box tube and abs connectos with aluminium plates for rigidity
12:57 PM DaPapa: i am currently designing it on form-z
12:57 PM IchGucksLive: https://www.sorotec.de/shop/CNC-Portalfraesen/
12:57 PM DaPapa: yes i know how to build one. just looking for a good setup with better drivers and motors than i have
12:58 PM IchGucksLive: there are 8Nm closed loop systems real cheep
12:58 PM IchGucksLive: and ofcause HWIN md 1605
12:59 PM DaPapa: for my current cnc i have this: http://www.ebay.co.uk/itm/Advanced-3Axis-CNC-TB6560-Stepper-Driver-Keypad-Display-Nema17-Motors-PSU-/401366699395?epid=886995463&hash=item5d7351cd83:g:DKoAAOSwpHFZazh2
12:59 PM IchGucksLive: use the better performence on TB6600
12:59 PM IchGucksLive: 8USD for a axis
12:59 PM IchGucksLive: more Volts
12:59 PM DaPapa: im currently looking at this: http://www.ebay.co.uk/itm/Germany-Ship-4Axis-Nema23-stepper-motor-425oz-in-3A-Driver-CNC-control-kit/281913332881?_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D45732%26meid%3D8e9895c824314ba28255d61c864ab0da%26pid%3D100005%26rk%3D1%26rkt%3D6%26mehot%3Dpp%26sd%3D201687135331&_trksid=p2047675.c100005.m1851
01:00 PM DaPapa: so i was looking for those that had experience with those drivers
01:00 PM IchGucksLive: i use them in my education mashines and even on plasma they run perfect
01:01 PM IchGucksLive: if you can affort the 542 go for them
01:01 PM IchGucksLive: http://www.ebay.de/itm/DE-Ship-3pcs-High-Torque-3Nm-425oz-in-Nema-23-Stepper-Motor-CNC-Mill-Router-/331469669081
01:01 PM DaPapa: ok great thanks
01:01 PM DaPapa: another question
01:01 PM IchGucksLive: http://www.ebay.de/itm/Ship-From-EU-Wantai-4Axis-Nema23-Motor-Driver-DQ542MA-4-2A-50V-128Micro-CNC-Cut-/171905757394
01:01 PM IchGucksLive: on that system you can go 48V
01:02 PM DaPapa: how feasible is it to run two motors on the 100mm axis? one on each side? ive seen this on some high end machines
01:02 PM IchGucksLive: that makes your speed going gracy
01:02 PM IchGucksLive: at 600mm Y not nessesury
01:02 PM DaPapa: 1000mm axis*
01:03 PM IchGucksLive: 1000mm is the way to go
01:03 PM DaPapa: ill show what i mean
01:03 PM IchGucksLive: i kow
01:03 PM archivist: DaPapa, linuxcnc does know about two motors on an axis
01:04 PM DaPapa: http://www.probotix.com/CNC-ROUTERS/NEBULA-CNC-ROUTER
01:04 PM IchGucksLive: as i said 1000mm Y is the way to do it
01:05 PM IchGucksLive: below 750mm no need
01:05 PM IchGucksLive: but also no problem
01:05 PM IchGucksLive: the bent on a 750mm Y at Hwin rails is less then 0,1mm
01:06 PM IchGucksLive: at standard 1:1 ZX dimantion
01:06 PM DaPapa: you are correct gucks. but could i not wire the x axis output from the breakout board to 2 of the stepper drivers?
01:06 PM IchGucksLive: meaning 170mm Z hight Railkblocl distance 200mm
01:06 PM Crom: or just go with closed loop integrated steppers... http://jmc-motor.com/products.php?cid=248&id=118
01:07 PM archivist: DaPapa, no you dont do that, you need to keep square
01:08 PM archivist: so home separately
01:09 PM IchGucksLive: http://www.ebay.de/itm/DE-EU-3X-4-5N-m-Closed-Loop-Servo-Motor-Nema34-82mm-Kit-6A-HSS86-Hybrid-Driver-/152673291293
01:09 PM IchGucksLive: archivist why did he leave
01:10 PM archivist: dunno
01:10 PM DaPapa2: sorry i lost connection
01:10 PM archivist: he is back
01:10 PM IchGucksLive: DaPapa2: you got enoph pins
01:10 PM IchGucksLive: so go for a 4th driver
01:10 PM IchGucksLive: http://www.ebay.de/itm/DE-EU-3X-4-5N-m-Closed-Loop-Servo-Motor-Nema34-82mm-Kit-6A-HSS86-Hybrid-Driver-/152673291293
01:10 PM IchGucksLive: http://heimwerkermarkt-tretter.de/4achs_elek
01:11 PM DaPapa2: as i was saying could i not wire the x-axis from the breakout box to 2 of the stepper drivers so they both recieve the same signal at the same time?
01:11 PM IchGucksLive: this is the same case
01:11 PM IchGucksLive: no dont do that
01:11 PM DaPapa2: dont think it wouldnt work?
01:11 PM IchGucksLive: let the driver motor config be on its own
01:11 PM IchGucksLive: just hook up the signal in Lcnc
01:12 PM DaPapa2: how would that duplicate to 2 motors?
01:12 PM archivist: DaPapa2, linuxcnc does the connection AFTER they are homed separately, keeps the gantry square
01:12 PM IchGucksLive: the signal goes out to 2 drivers
01:12 PM DaPapa2: o you mean the output from linux cnc could be directed to 2 channels on the breakout board
01:13 PM IchGucksLive: yes
01:13 PM DaPapa2: makes sense linuxcnc does have the ability to control 5 axis.
01:13 PM DaPapa2: good idea
01:13 PM archivist: 9 axis :)
01:13 PM IchGucksLive: 12 if you include the TC chain
01:13 PM DaPapa2: and this kit has 4 drivers and motors
01:13 PM DaPapa2: http://www.ebay.co.uk/itm/201687135331
01:14 PM archivist: gantry is a special setup
01:14 PM DaPapa2: 9 axis :P multiple parallel ports correct
01:14 PM archivist: yes
01:14 PM archivist: or an fpga card
01:14 PM IchGucksLive: DaPapa2: use the better BOB as on my cabinets
01:15 PM IchGucksLive: the one included is crap
01:15 PM DaPapa2: i happen to have a spare gigabyte d525 that i hear is good for linuxcnc
01:15 PM IchGucksLive: cool
01:15 PM DaPapa2: yeah im looking at this BOB:
01:15 PM IchGucksLive: then it might be the best to go for 5i25
01:15 PM DaPapa2: http://www.ebay.co.uk/itm/401376751758
01:16 PM DaPapa2: it has 5 axis so im thinking 1 axis for z, 1 for y, 2 for x, and then 5th axis for lathe
01:16 PM IchGucksLive: DaPapa2: http://www.ebay.co.uk/itm/331632334051
01:17 PM IchGucksLive: 5th is 16/17
01:17 PM DaPapa2: yes ive seen this. but i like the idea of manual control with display. useful for using it to make quick manual cuts
01:17 PM DaPapa2: 16/17?
01:17 PM IchGucksLive: so best to use for switching power
01:17 PM IchGucksLive: Parport pin
01:17 PM DaPapa2: ok
01:18 PM IchGucksLive: 4 is ok
01:18 PM DaPapa2: no good for lathe axis then?
01:18 PM IchGucksLive: 5 only if needed
01:18 PM IchGucksLive: if you need it then ok
01:18 PM DaPapa2: as i said i like the idea of using 2 motors on x axis as my gatry will be heavy
01:18 PM IchGucksLive: but better to go for second parport
01:18 PM DaPapa2: ok good plan
01:18 PM IchGucksLive: itsa 10Euro for double lpt
01:19 PM DaPapa2: the gigabyte board i have has onboard parallel and a pci slot
01:19 PM IchGucksLive: remember better to go E-save
01:19 PM DaPapa2: e-save?
01:19 PM IchGucksLive: as relai shout down Power
01:19 PM IchGucksLive: this BOB can do a VFD spindle
01:20 PM IchGucksLive: if you plan the BIG i can give you a Wirerplan for cabinett
01:20 PM DaPapa2: im using a makita router, well the katsu version
01:20 PM DaPapa2: works very well on my current cnc and only costs £30
01:20 PM IchGucksLive: http://heimwerkermarkt-tretter.de/5achs_elek
01:20 PM DaPapa2: so if it does die its very cheap to replace
01:21 PM IchGucksLive: this is the cabinett as your parts
01:21 PM IchGucksLive: 5axis + I7O
01:21 PM IchGucksLive: i/o
01:21 PM DaPapa2: nice
01:22 PM IchGucksLive: you need the link for the BOX ?
01:22 PM DaPapa2: when i finish the design on form-z ill jump on here and show you guys. i think you will like
01:22 PM DaPapa2: no im building a custom enclosed cncmachine so no seperate boxis needed
01:23 PM DaPapa2: reduce the noise and dust in my workshop :P
01:23 PM IchGucksLive: DaPapa2: here are my designes https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos
01:23 PM DaPapa2: very nice.
01:24 PM IchGucksLive: https://www.youtube.com/watch?v=u5v74lU3KUI like you gone build
01:24 PM DaPapa2: mine will be similar to this. but bigger.
01:24 PM DaPapa2: https://s-media-cache-ak0.pinimg.com/originals/c0/94/d8/c094d80ca516cd8585ed746d96229f0b.jpg
01:25 PM IchGucksLive: so a high rail system
01:26 PM IchGucksLive: therfor you gone ask 2 motors
01:26 PM DaPapa2: x axis (1000mm) will have 4 supported rails. 2 at the bottom of the gantry and 2 at the top. they are going to b slightly offset so i dont loose much rail travel. so from the 1000mm rails i should get 850mm travel
01:27 PM IchGucksLive: DaPapa2: 830is best to go
01:28 PM IchGucksLive: DaPapa2: keep the 4/5 sytem in minde on construction use a timebelt 20/25 to get a BEST Speed Torque precision setup
01:28 PM DaPapa2: hard to explain it. but ill finish the design soon and ill upload some pics
01:28 PM DaPapa2: im using ball screws
01:28 PM IchGucksLive: thats WHY
01:29 PM IchGucksLive: 400Steps meets 5mm
01:29 PM IchGucksLive: 5/4=1,25
01:29 PM IchGucksLive: 25/20=1,25
01:29 PM DaPapa2: my current cnc has hex screws and they are not great
01:29 PM IchGucksLive: 400steps *1.25 =500
01:30 PM IchGucksLive: 5/500=0,01
01:30 PM IchGucksLive: DaPapa2: Hex = TR16*4
01:31 PM DaPapa2: ill show what i have purchased for the new machie
01:31 PM IchGucksLive: no need
01:31 PM IchGucksLive: we kow the system
01:31 PM DaPapa2: http://www.ebay.co.uk/itm/SBR20-Linear-Rail-3-Ballscrew-RM1605-350-650-1050mm-Sbr20uu-600mm-Couplers/202031896475?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
01:31 PM DaPapa2: i also have an addition pir of 1050mm supported rails
01:31 PM IchGucksLive: 1605 is the min limit on 1000 you shodt have used 2005
01:32 PM IchGucksLive: if you dont connect straight by copplers you get a better mashine
01:32 PM IchGucksLive: on using timingbelt system
01:33 PM IchGucksLive: and the Steppers are back from workroom
01:33 PM DaPapa2: i now they will have to mounted accurately. but i can use tmy current cnc machine to make the mouting holes pretty accurate
01:33 PM DaPapa2: know*
01:33 PM IchGucksLive: up to you we only can tell you
01:34 PM DaPapa2: for sure
01:34 PM IchGucksLive: on 800steps you loose up to 25%
01:34 PM DaPapa2: i appreciate the advice
01:34 PM DaPapa2: loose 25% what?
01:34 PM IchGucksLive: so 400 and timingbelt will give you mutch more
01:35 PM IchGucksLive: DaPapa2: Speed and Torque
01:35 PM DaPapa2: ah i see
01:35 PM IchGucksLive: and if you go belo2w 36V it will add another 25%
01:35 PM DaPapa2: i have no experience with timing belts on cnc machines. how are they implimented? and which ones do i use?
01:36 PM IchGucksLive: depending on friction you may end up at 30% performence
01:36 PM IchGucksLive: T5
01:36 PM IchGucksLive: 16mm width at 3Nm
01:37 PM IchGucksLive: 20teeth to the stepper and 25teeth to the ballscrew
01:37 PM DaPapa2: mmm
01:37 PM DaPapa2: ok
01:37 PM DaPapa2: sounds interesting
01:37 PM DaPapa2: i wonder tho. would this be more efficient than using 2 motors on the x axis? the y axis should be ok as should the z
01:39 PM IchGucksLive: as i said we only can tell you what we got expirinced
01:39 PM Crom: wouldn't be more efficient, it would be most probably cheaper
01:39 PM IchGucksLive: Crom: is wright as on double bearing
01:40 PM DaPapa2: the reason i liked the idea of tow motors/screws on the x axis is the fact it would help iliminate any potential skew
01:40 PM DaPapa2: two*
01:41 PM IchGucksLive: wright but keep in mind the ballscrews are rolled not grinded
01:41 PM IchGucksLive: if you dont get 2 out of the same series you also can get in trouble
01:41 PM DaPapa2: yes.. getting the gantry on to the two screws would be difficult initially
01:42 PM IchGucksLive: the C5 or C7 quality deffers up to 0,3mm in lengt at 500mm
01:42 PM Crom: Veterans Administration has finally finish my remanded claim. I got 100% -- with a 80%, 40%, and 40% and the 30% I had. My paycheck went from $534 to $3000 a month!
01:42 PM DaPapa2: congrats crom
01:42 PM IchGucksLive: so Crom now a big servo is in the mind :P
01:43 PM roycroft: or dinner?
01:43 PM IchGucksLive: the Real 20m/min
01:43 PM IchGucksLive: a real bitbreaker
01:44 PM IchGucksLive: ok im off
01:44 PM IchGucksLive: Gn8 from Germany
01:44 PM DaPapa2: laters gucks
01:44 PM IchGucksLive: DaPapa2: think first build whise
01:44 PM DaPapa2: im off too. need to finish tweaking the design
01:45 PM Crom: IchGucksLive: 1st pay off old bills, 2nd get a van for me, 3rd take my cadillac to the shop for an engine rebuild., finish redoing my bathroom, pour a slab for my shop, build shop, order lathe and mill from little machine shop.
01:49 PM Crom: LMS will order any SIEG machine you want since they are a SIEG dealer.
01:57 PM hazzy2 is now known as hazzy
02:53 PM JT-Shop: pretty short list...
03:14 PM Deejay: gn8
03:35 PM Tom_itx: pretty quiet channel
03:36 PM JT-Shop: yup
03:38 PM phipli: Sure you don't just have the volume turned down?
03:45 PM Tom_itx: guess i'll go see if remap works
03:48 PM Tom_itx is now known as Tom_L
03:48 PM XXCoder: Tom_L: congats your nick remap worked!
03:48 PM * JT-Shop goes back to digging terminal post holes
03:50 PM jdh: just usw din rail terminals
03:51 PM * JT-Shop doesn't think a din rail will hold a 5' chain link fence
03:59 PM Tom_shop: keep getting ngc file not found change.ngc
03:59 PM Tom_shop: SUBROUTINE_PATH = /home/tom/linuxcnc/nc_files/:/home/tom/linuxcnc/nc_files/ngcgui_lib:/home/tom/linuxcnc/nc_files/ngcgui_lib/utilitysubs
03:59 PM Tom_shop: there's a copy of it in every one of those directories now
04:03 PM JT-Shop: did you restart axis?
04:04 PM JT-Shop: yea, I'm only a month behind on paperwork
04:05 PM Tom_shop: yes i restarted
04:05 PM Tom_shop: several times
04:06 PM Tom_shop: pretty soon change.ngc will be in every directory i have
04:11 PM roycroft: only a month behind?
04:11 PM JT-Shop: yup
04:11 PM roycroft: i think my books have been reconciled through april now
04:11 PM roycroft: maybe only march, but i think i finished april
04:11 PM roycroft: when the weather gets nicer i tend to not want to spend much time on the computer doing that kind of stuff
04:12 PM roycroft: so everything falls behind until the rainy season starts, which i hope is soon
04:12 PM Tom_shop: is the path relative to where the .py file is?
04:12 PM roycroft: especially since i can hardly breathe again today because of the smoke
04:15 PM roycroft: aqi is up to 220 now
04:16 PM tpra: hi
04:16 PM roycroft: that's in the middle of the "very unhealthy" range, getting close to "hazardous"
04:21 PM JT-Shop: Tom_L: what .py file?
04:39 PM gloops is now known as Goodlord
04:41 PM Goodlord is now known as gloops
05:05 PM gloops: what diameter shank router bits?
06:01 PM Tom_L: JT-Shop, stdglue.py etc
06:02 PM Tom_L: or toplevel.py
06:23 PM * JT-Shop wonders what happened to remap in the pdf docs...
06:30 PM Tom_L: needed an '/' in the path
06:30 PM Tom_L: on the end
06:31 PM Tom_L: decided to hook up a spare 7i90 so i can sit in here and debug it
06:48 PM JT-Shop: when you figure it out tell me what to fix in the docs
06:51 PM devlap: I was googling setting up my chinesium cnc engraver with a mach 3 board. I found chat logs in this channel with someone essentially with the same issue I was having.
06:51 PM devlap: http://emclog.archivist.info/previous.php?day=410 2016-07-15 22:57:13
06:51 PM devlap: ai6ci
06:52 PM devlap: http://www.gbeshop.com/InfoBase/SAVEBASE/PKG/004393/Image/New_5axis_breakout_board_interfaces_fw_r2_c1.jpg He's got the same board I do. and has commented that he thinks X1 is fwd/reverse for the VFD spindle which I concur with.
06:52 PM devlap: Not sure where that would plug into on the parallel port control card however.
07:14 PM Tom_L: JT-Shop, remap works
07:15 PM Tom_L: however, in the ngc file called the first line is M19 R0 P1 and the next line is M6
07:15 PM Tom_L: i had to comment out the M6 for it to work as i expected it to
07:16 PM Tom_L: i mapped motion.spindle-locked signal to the hal_manualtoolchange pin
07:16 PM Tom_L: so it wouldn't call up the dialog until the spindle had oriented
07:17 PM Tom_L: so now it's just a matter of putting in your own individual commands for carousel movement etc
07:17 PM Tom_L: afte the spindle orient finishes
07:18 PM Tom_L: hah, doing a cattle drive down the middle of the highway near houston
07:20 PM Tom_L: i think the hard part to this was figuring out orient
07:25 PM Tom_L: and the crap spindle motor so the PID doesn't work right but well enough for this exercise
07:25 PM Tom_L: a decent spindle would be easier to orient i think
08:36 PM Tom_L: JT-Shop, i'm not sure there's a problem with the docs
09:05 PM Cromaglious_: now waiting for money to show up.... I'm officially a 100% disabled veteran.
09:06 PM SpeedEvil: yay!
09:06 PM SpeedEvil: :(
09:06 PM SpeedEvil: That wierd combination of soul-crushing and relief.
09:06 PM Cromaglious_: Still the same I've been for the last 9 years (well steady but slight decline)
09:07 PM Cromaglious_: going from $534 a month to $3078 a month WOOOO HOOOO
09:11 PM SpeedEvil: Congrats. I recently got to top level benefits in the UK. It takes some load off just being able to buy services and offload them.
09:12 PM Cromaglious_: Sure does... now waiting for back pay to show up... I have been authorized $192K, still missing $100k... Just waiting for it to hit the bank account.
09:13 PM SpeedEvil: It would be rather nice if they'd just make the right decision first time.
09:13 PM Cromaglious_: yep... I'd be so much money ahead... I'd have Air Conditioning in the house and cars, newer cars too
