12:52 AM IchGucksLive: morning from germany
12:57 AM IchGucksLive: off 2 garden
01:59 AM Deejay: moin
02:05 AM gloops: right, today i sort this z crap out once and for all
02:05 AM gloops: no more random trying this or that
02:06 AM gloops: i will undertake a proper methodical testing of the circuits and make analysis
02:12 AM gloops: the problem only arose since i rewired - this seems to suggest the problem is not component failure, but wiring mistake
03:32 AM gloops: resolved!
03:32 AM XXCoder: yay!
03:32 AM XXCoder: so, what was?
03:32 AM gloops: well, phase wires were crossed lol
03:33 AM gloops: i ran short length of colour code wires from drive - these connected to plain black shielded cable - at the other end they connected to stepper motor colour wires
03:34 AM gloops: unfortunately i got the colours mixed at driver end
03:34 AM gloops: so i apologise for the whining and time wasted asking in here, it was my fault
03:35 AM gloops: i will also write a letter of apology to the chinese PM, it isnt the fault of the chinese
03:39 AM gloops: if youre having these kind of problems it sometimes pays to take a complete break and come back with a fresh outlook, id checked the wiring to the drivers 20 times, it was right, i didnt check that id connected the colours to the shielded cable correctly though
03:39 AM XXCoder: lol that could happen yeah
03:40 AM gloops: but how did the 8 wire stepper work? lol, must be some possible config with crossed signals it can work on 4 wires, no wonder i couldnt get it to work on 8
03:41 AM gloops: crossed phase wires
03:44 AM XXCoder: no idea but in least its running !
03:44 AM gloops: yeah thats all that matters right now
03:46 AM gloops: the sequence of faults was misleading - spindle moving z axis - this was a spindle short, red herring not related to wiring issue, drivers werent faulty, changing drivers didnt work - it wouldnt, motor was not faulty changing it wouldnt make any difference
03:47 AM gloops: but as the 8 wire motor was stepping seemingly correctly, i didnt suspect crossed wiring
03:54 AM XXCoder: funny combination of issues
03:54 AM XXCoder: anyway any sparky probloem now?
03:55 AM gloops: no thats gone - i hope
03:55 AM gloops: that was something else that could have been contributing
03:57 AM gloops: strange things happen un-noticed in the dark days alone in the garage building these things, one problem after another, lots of tedious mechanical issues etc, easy to overlook something
04:08 AM XXCoder: yeah
04:08 AM XXCoder: so, whats next for you?
04:19 AM gloops: well all seems ok homing and everything, spindle working, ive got slight scale matter on X which is my pulley tooth counting i think, do that in a minute, then got code ready to surface table off, THEN maybe do some proper test cuts
04:19 AM gloops: will need getting finally square etc
04:20 AM gloops: that should be easy as X is squared by moving homes, i made home switches with slots so can adjust them
04:20 AM XXCoder: cool
04:21 AM gloops: probably grown a bit cycnical during the course of this because im always waiting for the next unfathomable problem now lol, i think its ok now though apart from routine setting up
06:22 AM gloops: getting a stop message - program exceeds machines min limits - min limit is .0001 - g code is asking to go to 0.000...a bit of reading to do i think
06:23 AM XXCoder: soft limit should be 0
06:23 AM XXCoder: and hard limit at slight negative I think
06:25 AM gloops: sorry machine min limit is -0.0001 - thats standard stepconfig limit
06:27 AM XXCoder: hmm someone will answer evenually
06:48 AM gloops: got problem thanks - code not machine
07:02 AM hazzy-dev: morning
07:40 AM Tom_L: 18°F & snow
07:41 AM Tom_L: from 70+ yesterday
07:46 AM JT-Mobile-: 29F and light snow in Poplar Bluff
07:46 AM JT-Mobile-: 66F and light rain in LaPlace
07:51 AM Tom_L: did you ride or drive there?
07:57 AM JT-Mobile-: drive the Honda Civic
07:57 AM JT-Mobile- is now known as JT-Mobile
07:57 AM JT-Mobile: monsoon season
08:10 AM holzjunkie1 is now known as holzjunkie
09:03 AM gloops: anybody ring archivist?
09:34 AM gloops: bed surfacing underway, 50% complete no problems
09:40 AM holzjunkie1 is now known as holzjunkie
09:55 AM gloops: damn, rtai unexpected realtime delay error
09:56 AM gregcnc_: trying to run too fast, or one of those once in an hour/day/week extra long cycles
09:58 AM gloops: well had surfaced over half the board, about 30 minutes, not trying to go too fast i dont think
09:59 AM gloops: i was just beginning to get a bit of confidence in it back lol, was running perfect
10:00 AM gregcnc_: not feed but base period
10:00 AM gloops: i wonder if the screensaver is having effect, theres nothing else running on the computer
10:00 AM gregcnc_: screensaver should be disabled
10:00 AM gloops: right, yes im going to have to look at those and make a proper job of the stepgen etc
10:01 AM gloops: i will, ive had my time on it today now, but very encouraging!
10:02 AM gloops: i actually noticed a change in tone from something, before one x motor stalled, or thought i did
10:12 AM gloops: ah well, suppose there will be some of this for a while, i might run it again now heh with screensaver off
10:13 AM gregcnc_: what did latency test show and how close are you running to that value?
10:13 AM Tom_L: mine still goes blank after a while even with it off, not sure if it's part of the monitor or something else
11:05 AM hazzy1 is now known as hazzy
11:16 AM gloops: success, ran full cut no problem
11:27 AM IchGucksLive: hi all
11:28 AM IchGucksLive: sad car terror in germany
11:28 AM IchGucksLive: gloops, how coudt there be calculation problems on pulley
11:28 AM gloops: yeah just saw that Ichs another van into the crowd
11:29 AM gloops: Ichs i didnt count teeth on big pulley properly, well i did first time but i forgot lol
11:29 AM IchGucksLive: this small iron pins woudent stop a fast hevy car at all
11:29 AM IchGucksLive: you did buy them with a number
11:29 AM IchGucksLive: no need to count
11:30 AM IchGucksLive: did you folow my atwise on 20/25
11:30 AM gloops: yeah but its been that long i forgot, i thought they were 62, theyre 64
11:30 AM gloops: not for these no, id already got them
11:30 AM IchGucksLive: why that many
11:30 AM IchGucksLive: ok up to you
11:30 AM gloops: box of used pulleys
11:31 AM IchGucksLive: it does not fit the 1,25 divider
11:31 AM gloops: have got bigger motors for X axis anyway so pulleys will be coming off in the future
11:31 AM IchGucksLive: to give the best speed at max force best precision
11:32 AM IchGucksLive: the T5 25 will fit a 10mm pin
11:32 AM IchGucksLive: the AT5 even 12mm
11:32 AM IchGucksLive: ballscrew ending
11:33 AM IchGucksLive: and the 10mm Belt pulls 3Nm the 16 8Nm
11:33 AM gloops: well apparently the bigger motors are up for 1600 rpm so will see
11:33 AM IchGucksLive: the 25mm belt with can go for 12Nm
11:34 AM IchGucksLive: the belt drive will take up to 5000
11:34 AM gloops: it has surfaced 1000x800 in about 45 minutes, at half speed, not so bad
11:34 AM IchGucksLive: maedler got a nice tool to calculete the numbers
11:35 AM IchGucksLive: stepwidth ?
11:35 AM gloops: 10mm
11:36 AM IchGucksLive: at 1800mm/min ? with G64 P0,2
11:36 AM gloops: 2100/min
11:36 AM IchGucksLive: gloops, did you use my python script
11:37 AM gloops: no not had chance to do any proper tests yet, will be working on it again tommorrow now
11:37 AM IchGucksLive: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_LinuxCNC_G-Code_Generators#Rectangular_Circular_Pocketing_Generator
11:38 AM gloops: ill save that and look through it later thanks
11:39 AM gloops: first thing is to get gantry properly square
11:39 AM IchGucksLive: usefull simple tools that dident find the way into lcnc
11:39 AM gloops: yes stuff like that is helpful for setting up
11:39 AM IchGucksLive: gloops, i get a wood cut from Homedepo about 600x600
11:40 AM IchGucksLive: then i made a drill straight 5mm(M6) middle thrue or if it bends on the side of the motor
11:40 AM gloops: luckily there are a few small timber places near here, cut sheets up free etc
11:40 AM IchGucksLive: 50mm hole space
11:41 AM IchGucksLive: there i pressed the wood in with m6 screws
11:41 AM IchGucksLive: then i did als long as it took to get the Y to straight dial the Wood
11:41 AM IchGucksLive: 0,01
11:42 AM gloops: thats good
11:42 AM IchGucksLive: at a other mashine i goot a pice from a carpender that got edge bends on
11:43 AM IchGucksLive: but i discoverd that homedepo has wood also with the bend on it to get a better dial
11:43 AM gloops: a kitchen cupboard door is probably pretty true to square
11:43 AM gloops: will be cut on big cnc
11:44 AM IchGucksLive: gloops, 800x4000 3,50euros https://www.hornbach.de/shop/Regalboden-weiss-16x400x800-mm/3022795/artikel.html?varCat=S4187##v3022693
11:44 AM IchGucksLive: this are the perfect sraight
11:45 AM IchGucksLive: i did drive the plasma cut gcode of the fishmetallfirer place
11:45 AM IchGucksLive: and remesurerd
11:45 AM IchGucksLive: alll clear
11:46 AM IchGucksLive: i need to take a image of the 4 mashines we made
11:46 AM gloops: yeah something like that, i dont need .001 for what ill do anyway lol
11:46 AM gloops: anyway gtg, bbl
11:46 AM IchGucksLive: im off 2
11:52 AM tensaiteki: anyone have any idea why "loadrt trivkins coordinates=xyzy" won't work on 2.7.12?
11:54 AM tensaiteki: dmesg says: "trivkins: Unknown parameter 'coordinates'"
12:06 PM MrHindsight: https://www.forum.linuxcnc.org/38-general-linuxcnc-questions/32733-trivkins-unknown-parameter-coordinates-in-linuxcnc-2-7-8
12:12 PM tensaiteki: I saw that post, but it wasn't very helpful. That guy seems to have updated to 2.8 and used a config from the joints-axes branch
12:18 PM gregcnc_: I thought gantry needed 2.8
12:18 PM gregcnc_: too late
12:25 PM MrHindsight: he upgraded since it doesn't work in 2.7
12:26 PM MrHindsight: wasn't that obvious?
12:26 PM gregcnc_: enough searching will turn that up
12:28 PM gloops: latency test doesnt seem to work in 2.8
12:30 PM gloops: stepconfig has max jitter test, but its quick
12:31 PM gregcnc_: http://linuxcnc.org/docs/2.7/html/install/latency-test.html
12:33 PM gloops: max jitter = 30000ns
12:33 PM gloops: 33333hz
12:34 PM gloops: what kind of base period would you go with for those results?
12:36 PM gregcnc_: http://linuxcnc.org/docs/2.7/html/config/stepper.html
12:36 PM gregcnc_: http://linuxcnc.org/docs/2.7/html/motion/tweaking-steppers.html
12:36 PM gloops: thank you lol, yes i need to re-read all this, and im going to
12:37 PM gloops: im not sure why ive set base period to 100 000 based on those results
12:39 PM gregcnc_: it a little conservative, but should not have realtime errors
12:40 PM gloops: i remember i did allow plenty, maybe a bit too much
12:40 PM gregcnc_: too much only limits max step frequency it doesn't cause errors
12:42 PM MrHindsight: might be SMM, BIOS/EFI etc still causing delay errors
12:42 PM MrHindsight: some boards have firmware that just sucks
12:43 PM gloops: it was only one error in about 2 hours of cutting, im sure the screensaver jittered it, but anyway, looking at that is another day i suppose
12:44 PM gloops: i need to train a pigeon to peck the space bar every 5 minutes
12:45 PM MrHindsight: with Debian you might have to kill blanking in the kernel
12:45 PM gloops: that sounds simple to do...
12:46 PM MrHindsight: try these first https://unix.stackexchange.com/questions/168763/how-to-stop-the-screen-from-blanking-blacking-out
12:47 PM IchGucksLive: hi
12:48 PM MrHindsight: not the LCNC devs but the KDE and similar devs hard code blanking on, because fuck you I'm the dev
12:48 PM MrHindsight: is often the case
12:48 PM gloops: yeah ive had a quick look online it does seem a tricky one
12:49 PM IchGucksLive: gloops, at 30k you can go for the standard 100k
12:50 PM IchGucksLive: hi shags
12:51 PM IchGucksLive: shags, how is the weather in oklahome any tornatos seen latly
12:51 PM IchGucksLive: gloops, go for 50k so half the main stream
12:53 PM IchGucksLive: gloops, what ACC are you going i stay below 250
12:53 PM gloops: hmm, yes i will do some calculations
12:53 PM gloops: well below 250
12:54 PM IchGucksLive: at VEL 80
12:54 PM IchGucksLive: i use Acc 225
12:54 PM gloops: much lower, 60
12:54 PM IchGucksLive: BY the WAY can someone tell me if i can set the RAPID default at startup
12:55 PM IchGucksLive: manual jog is well documentad
12:56 PM IchGucksLive: gloops, do you got the ACC lower then the VCC
12:56 PM IchGucksLive: Vel
12:56 PM gloops: cant remember which way now but i followed the docs
12:57 PM IchGucksLive: not a good ide it will interfear the interpreter
12:57 PM IchGucksLive: as it likes to be mutch highr
12:57 PM IchGucksLive: most rn a ACC 500+ in reatch 750
12:58 PM IchGucksLive: but my mashene stalls at that numbers
12:58 PM IchGucksLive: 275 is the max at my setups
12:58 PM IchGucksLive: so i go 225 and stay save
12:59 PM gregcnc_: ichs DEFAULT_LINEAR_VELOCITY
12:59 PM IchGucksLive: is the jog for manuell
12:59 PM gloops: yes i did that the other day
01:00 PM IchGucksLive: ok you got your first light
01:00 PM IchGucksLive: and chiped for 45min
01:00 PM IchGucksLive: so all clear for now
01:00 PM IchGucksLive: gloops, now try the hardway
01:00 PM gloops: yeah, some progress at least, no mechnical problems so far
01:01 PM gloops: ill soon memorise all this now im actually using linuxcnc
01:02 PM IchGucksLive: https://www.youtube.com/watch?v=UdvROAlCMMQ
01:02 PM IchGucksLive: if it takes this kind it takes AL
01:03 PM IchGucksLive: AL at 0,5mm chiplöoad ofcause
01:03 PM IchGucksLive: this wood is way harder then aL
01:04 PM gloops: lol, well i wont be trying to push things at this point, ill just get things cutting nicely nice and slow
01:04 PM IchGucksLive: a 8year old graveyard cross
01:04 PM IchGucksLive: as i recicle them for forest signes
01:04 PM gloops: is that what that was for?
01:05 PM IchGucksLive: http://heimwerkermarkt-tretter.de/hs_2.jpg
01:05 PM shags: hello IchGucksLive
01:05 PM IchGucksLive: ;-)
01:05 PM shags: sorry for the super fast response
01:06 PM IchGucksLive: shags, im in germany
01:06 PM gloops: very nice Ichs
01:06 PM IchGucksLive: gloops, http://heimwerkermarkt-tretter.de/hs.jpg
01:06 PM shags: no tornadoes lately. snow today.. :(
01:07 PM IchGucksLive: shags, not that offen at this time in year
01:07 PM shags: no it is normally warm and beautiful.
01:08 PM shags: but spring will be spring
01:08 PM IchGucksLive: today here all farmers in fields
01:08 PM roycroft: we're going to have 30+mm of rain today and 100km/h winds
01:08 PM roycroft: welcome to april in the pacific northwet!
01:08 PM shags: i have been using Mach3 to control my router for the last few years.
01:09 PM shags: and am just now getting into Linux.
01:09 PM IchGucksLive: shags, i dident see a microsoft PC since 20008
01:09 PM IchGucksLive: 2008
01:09 PM shags: and i wouls like to use something that will run native on my machines
01:09 PM IchGucksLive: all open source here and running perfect on more then 500 CNC mashines
01:09 PM shags: i have had enough of microsoft
01:10 PM IchGucksLive: shags, http://tv-profi-gmbh.de/masch_baumh_k.jpg
01:10 PM shags: roycroft: where are you?
01:10 PM roycroft: oregon, in the willamette valley
01:10 PM shags: beautiful there
01:11 PM shags: i am in north east oklahoma, grand lake
01:11 PM IchGucksLive: im off Gn8 from germany
01:12 PM shags: you are ate up with it... lololol
01:12 PM shags: what machines are those
01:12 PM roycroft: so i can find the dimensions of wood biscuits all over the place
01:12 PM roycroft: but dimensions for biscuit slots?
01:12 PM roycroft: other than width, nowhere
01:13 PM gloops: shags what router do you have?
01:13 PM roycroft: i'm going to have to go out to my shop and cut slots for #0, #10, and #20 and measure them
01:14 PM shags: i have a KRMx02. built from plans 102x50 cutting area
01:16 PM gloops: ahh full sheet, those KRMs look ok
01:26 PM shags: it has been a great machine. i really do not have any omplaints.
01:27 PM shags: graet for what i do. i am a cabinet maker and a 1 man shop so it really helps out
01:41 PM gloops: excellent, Ichs makes dozens of machines a year, for schools and stuff like that
01:46 PM pink_vampire: what is the correct height for a table for a bench-top lathe?
01:48 PM gloops: i dont think there is a standard height, make it so you are comfortable operating it
01:51 PM pink_vampire: https://www.youtube.com/watch?v=YNcHLU5-_FM
02:11 PM roycroft: well that was fortunate
02:11 PM roycroft: the wind had picked up
02:12 PM roycroft: the sky was sunny
02:12 PM roycroft: so i decided to try to cut the grass while i could, given that we're expecting 60-75mm of rain soon
02:12 PM roycroft: i got the front cut, and as i was moving the mower to the back yard the sky turned black
02:12 PM roycroft: i got the mower put away and made it back to my shop before the downpour started
02:20 PM XXCoder: hey pink_vampire
02:20 PM XXCoder: hows lathe restore go so far
02:20 PM pink_vampire: hi XXCoder!
02:24 PM gregcnc_: curious add-on high RPM coolant/air spindle http://sfi-toodle.com/
02:25 PM SpeedEvil: Interesting.
02:25 PM SpeedEvil: Do they mean 'crash resistant' ?
02:25 PM pink_vampire: hope you have good air supply
02:26 PM gregcnc_: yeha needs quite a bit of air or high pressure coolant
02:26 PM XXCoder: lol was about to say something about air "brownouts"
02:26 PM XXCoder: had it happen at work once. messed with lot of stuff
02:26 PM gregcnc_: most practical application would be engraving or similar light work
02:27 PM SpeedEvil: http://sfi-toodle.com/product-item/toodle-blue-131/ wait - water pressure?
02:27 PM gregcnc_: https://www.wto-tools.com/fileadmin/user_upload/_Kataloge_U1_PDF/CoolSpeed_mini_en.pdf
02:27 PM gregcnc_: yes coolant powered
02:27 PM XXCoder: SpeedEvil: and it changes bearings with tools.
02:27 PM XXCoder: so "maintance free"
02:27 PM SpeedEvil: XXCoder: yes, the inkjet printer model.
02:27 PM pink_vampire: SpeedEvil: some of them work on coolant pressure
02:27 PM XXCoder: indeed
02:28 PM XXCoder: funny thing is that bearings last far more than tools does
02:28 PM XXCoder: so I wonder if can change tools
02:28 PM gregcnc_: bearings that size are dirt cheap
02:28 PM SpeedEvil: http://sfi-toodle.com/wp-content/uploads/2016/05/high-res-Assembled-Tool-600.jpg
02:29 PM SpeedEvil: Also, this does not look particularly hard to copy.
02:29 PM gregcnc_: sure
02:29 PM XXCoder: easy to copy, easy to precisely copy?
02:29 PM SpeedEvil: Sure, there may be some secret sauce in getting the last 5% power out.
02:29 PM SpeedEvil: But even if you only get 50% of the nominal, that may be fine
02:29 PM XXCoder: "* Tool is not included."
02:30 PM XXCoder: I guess tool is seperately replacable then
02:30 PM gregcnc_: the bearings and turbine are pressed onto the tool itself
02:30 PM pink_vampire: it's look like the same idea as the friction grip that use in the dental ones
02:31 PM XXCoder: hm I guess small tool breakage errors would cost more
02:31 PM XXCoder: since it now costs trubine and 2 bearings as well as tool
02:31 PM gregcnc_: https://www.youtube.com/watch?v=TbarfpLycOQ
02:32 PM pink_vampire: get a dental one
02:32 PM XXCoder: greg lol transition between slides is way too slow
02:32 PM pink_vampire: the surgical arm, it take 2.4mm tools
02:32 PM SpeedEvil: Fucking insane coolant flow may also do interesting things
02:32 PM gregcnc_: i has to take endmills
02:34 PM gregcnc_: https://www.youtube.com/watch?v=c_Hl5OPrnW8
02:34 PM pink_vampire: https://www.ebay.com/itm/Dental-Surgical-Straight-Handpiece-1-1-Nose-Cone-With-External-Pipe/122570521471?hash=item1c89c5bb7f:g:PNgAAOSwTIhaa-xk
02:35 PM XXCoder: SpeedEvil: would be interesting to use coolant as spinning force, then use waste as cooling
02:35 PM SpeedEvil: XXCoder: I assumed that was what it did
02:35 PM XXCoder: but then coolant would have chips in it. so need to either super filter it or design it so it doesnt care
02:35 PM gregcnc_: high pressure coolant would be filtered
02:35 PM XXCoder: hmm was thinking air
02:38 PM XXCoder: yeah air lol. I'm wondering what it do with waste air. looks like it would spray air downwards
02:46 PM XXCoder: gregcnc_: so its powered by coolant?
02:46 PM XXCoder: thought it was air
02:46 PM gloops: i only read yesterday that recycle air control in a car can be lethal
02:46 PM hazzy-dev: It is quite common to have high speed spindles run off the thru the spindle high pressure coolant
02:47 PM gregcnc_: there are air and coolant versions
02:47 PM XXCoder: ahh
02:47 PM gregcnc_: these are cheap, much nicer units exist
02:47 PM XXCoder: I suppose that would work yeah. I guess only change is fin shape to better extract energy liquid vs air
02:47 PM hazzy-dev: I don't see what would prevent a miserly personfrom pressing the tool out and reusing the bearings on the Toodle :)
02:48 PM * hazzy-dev is thinking of 3D printed turbines ...
02:49 PM XXCoder: hazzy yeah though not filiment type, probably shatter under high speed unless really good fuse
02:49 PM gregcnc_: it seems they intend the bearings/turbine to be dispoable
02:50 PM XXCoder: yeah like speed said, inkjet mopdel
02:54 PM hazzy-dev: I guess since the bearings press directly onto the tool you are limited to tools with certain sized shanks, but I guess most small tools have shanks sized to go in shrink fit holders anyways
03:15 PM gloops: when eskimos go fishing, they dont look for fish
03:16 PM gloops: they look for the heron
03:22 PM gregcnc_: I'll remember that next time I'm at the market
04:03 PM gloops: https://www.telegraph.co.uk/news/2018/04/07/rare-owl-given-gift-flight-double-wing-transplant/?utm_campaign=Echobox&utm_medium=Social&utm_source=Twitter
04:04 PM gloops: hmm, headline looked interesting
04:04 PM gloops: a double wing transplant would be something
04:06 PM gloops: a handful of feathers transplant doesnt sound so impressive
04:11 PM Deejay: gn8
04:16 PM SpeedEvil: Also, I want to see a honey badger given a double wing transplant.
04:17 PM SpeedEvil: Owl is easy-mode.
04:17 PM gloops: a honey badger doesnt have the brain for wings
04:20 PM gloops: which in cnc terms would be like bolting 2 moped engines to your mill
04:21 PM SpeedEvil: Honey badger would fly through the power of pure rage though.
04:22 PM gloops: they wouldnt really be wings, they would be mere ornamental and utterly useless appendages
04:23 PM SpeedEvil: https://i.imgur.com/vzurPyb.gif
04:23 PM SpeedEvil: Proof! (not really)
04:24 PM gloops: adobe
04:24 PM SpeedEvil: More seriously, working out required power to weight and skeletal structure and muscle attachments for mythological creatures is fun.
04:26 PM gloops: fun in the doing a crossword with cryptic clues in a foreign language kind of way
04:27 PM gloops: that has given me a thought though, why has nobody built a spider cnc?
04:27 PM gloops: instead of octopod with suspended platform, why not something like a spider?
04:29 PM SpeedEvil: you mean with eight arms?
04:29 PM SpeedEvil: Or with a butt-spinner.
04:29 PM SpeedEvil: 3d printers pretty much are spiders, often with very tangled webs.
04:31 PM gloops: 8 legs
04:32 PM gloops: this cnc could also walk to the job
04:33 PM miss0r|office: Documentation for my machine is now complete.. It ended up being a 19.65mm thick pile of A4 paper...
04:34 PM miss0r|office: This is not the part of what I do that I particularly like :]
04:34 PM miss0r|office: I'll go to bed now. See you around
04:34 PM gloops: sounds like a load of EU red tape miss0r
04:46 PM gloops: hmm it has been done https://www.youtube.com/watch?v=quN37YskoaM
04:47 PM gloops: and it does walk to the job https://www.youtube.com/watch?v=7hEXwyJ2B78
05:22 PM pink_vampire: soooooooooooooo old!!!!!!
05:34 PM Crom_: still working on Xmu error... looking for the places to add the libs
05:57 PM andypugh: I am bidding on a slotting head for my milling machine. CNC slotting sounds like fun :-)
05:59 PM Tom_L: dunno about those, how would that be better than milling a slot?
05:59 PM Tom_L: like a broach?
06:00 PM andypugh: Keyways and internal splines.
06:00 PM Tom_L: yeah i see now
06:00 PM Tom_L: like a shaper
06:01 PM andypugh: Indeed.
06:01 PM ves: trying a make clean ; make -j4 to see if I can get Xmu linked in
06:03 PM ves: that did it!
06:05 PM ves: now to get 7i92M working... any chance of using a 7i92M with a standard ebay parallel break out board?
06:06 PM Tom_L: the IO probably won't align
06:06 PM Tom_L: you could make a cable...
06:07 PM Tom_L: 18..25 of a regular pp is GND
06:07 PM ves: on the Mesa site: The 7I92M uses standard parallel port pinouts and connectors for compatibility with most parallel port interfaced motion control / CNC breakout cards/ multi axis step motor drives, allowing a motion control performance boost while retaining a reliable real time Ethernet interface.
06:07 PM Tom_L: i would certainly compare the IO but that's just me
06:08 PM Tom_L: check one of the vhd files, i think they have the D connector pinout listed in some of them
06:12 PM ves: getting mesaflash, then going to read the manual front to back
06:26 PM andypugh: You can probably find a bitfile that matches your breakout board.
06:26 PM andypugh: (The bitfile determines which pin has which function, GPIO, step, dir, pwm etc)
06:26 PM andypugh: mesaflash -hmid will tell you what your current bitfile has.
06:29 PM Tom_L: 92m is the small ethernet card
06:29 PM Tom_L: 1 db25 and 1 header
06:30 PM Tom_L: 17 IO per
06:31 PM Tom_L: so all the 'signal' lines
06:34 PM Tom_itx: https://www.ebay.com/itm/5-Axis-CNC-Breakout-Board-optical-coupler-MACH3-Stepper-Motor-Driver-USB-cable/152656202014?epid=2175425386&hash=item238b04c91e:g:HTcAAOSw8yVZiq6N
06:34 PM Tom_L: that one looks like it might work
06:48 PM pcw_home: the 7i92 config for the common Sainsmart 5 Axis bob is 7i92_5ABOBx2D.bit
06:56 PM Tom_L: may be testing sooner than i thought... found a pc i forgot i had
07:02 PM MrHindsight: Tom_L: I have some of those
07:03 PM MrHindsight: I also have the little white mating plugs and crimp pins
07:03 PM MrHindsight: if you need

07:07 PM skunkworks: Tom_L: that one I have used. It is good - inputs need higher than 5v though iirc

07:10 PM MrHindsight: I've used it powered by the USB 5V
07:15 PM MrHindsight: who makes a decent LPT MPG?
07:27 PM JT-Mobile: you mean one that plugs into a parallel port?
07:28 PM MrHindsight: yes, or USB
07:29 PM MrHindsight: I have some Heidenhain but not sure if I can just swap the pins around and use them with LPT or LPT --> USB
07:30 PM JT-Mobile: dunno all my mpg's are wired into mpg inputs
07:30 PM JT-Mobile: usually the MPG part is 5v single ended 100 pulse per rev
07:39 PM MrHindsight: https://www.amikon-shop.de/heidenhain-elektron-handrad-hr-330-id-nr-251-534-11/elektronik-gesamt/heidenhain/a-13923/ have to find the specs
07:45 PM Loetmichel: re at home. what a day. woke up at 0600 today, drove 400km to my mother in law, renovated the new appartment 'til 2100, drove home. after 300km i felt sleepy so i parked for an hour and slept a bit with radio on. woke up, started the engine: *KLACK* *krrrrrrr*. Conclusion: the BMW convertible has not only to get those coilovers replaced with OEM suspension (ouch my back!), but also needs a
07:45 PM Loetmichel: new battery :-) (Btw: its now 02:42 over here)
07:45 PM jdh: go to sleep
07:46 PM MrHindsight: https://imagebin.ca/v/3xcX41CCBxna 12V with serial DTR and RXD
07:47 PM MrHindsight: Heidenhain HR330 MPG pinout ^^
07:48 PM MrHindsight: Loetmichel: did you get a jump?
07:49 PM Loetmichel: MrHindsight: i have a jumperbox in the car... "be prepared" ;)
07:53 PM MrHindsight: heh mine died recently, it used a sealed lead acid battery
07:55 PM * Loetmichel had the convertible parked at the company for the winter... and started it every 2 weeks or so the recharge the battery... which failed abour every other time. thats why a jumper box was handy. (needed it anyways for the last half year, so i packed it in the car when i switched back to the "sumer car" :-)
07:56 PM Loetmichel: mine has a 12V 7Ah AGM in it, too. but its only half a year old, so the batt in it is pretty "fresh"
07:57 PM MrHindsight: walmart started selling 18650 for $1ea
07:57 PM MrHindsight: will probably build the next battery in a box
08:07 PM ves: I bought a wireless HB04 -- didn't work. bought a usb wired hb04 -- it works
08:07 PM ves: how many mAh are they?
08:08 PM MrHindsight: 18650-3.7V-9800
08:09 PM ves: oh wow.. 18640 not 16450's
08:09 PM MrHindsight: they sell a ton of them now, they vary from 2.6 to 9.8Ah
08:10 PM ves: return the less than 8Ah?
08:10 PM MrHindsight: https://www.walmart.com/search/?query=18650%203.7v%20li-ion%20battery&typeahead=18650
08:11 PM ves: out of stock on 16pk: https://www.walmart.com/ip/16-pcs-Universal-18650-3-7V-9800-mAh-Rechargeable-Lithium-Batteries-Tip-Main-Batery-Cell-For-Flashlight-Torch-Camera/139896913
08:11 PM Loetmichel: MrHindsight: 9800 is a fake
08:11 PM MrHindsight: they have 100 and 1000 packs
08:12 PM Loetmichel: look at "known good" brands. they get about 3200mAh into an 18650 shape. more is not possible
08:12 PM Loetmichel: and even those 3200s are pusing safety limits with thin seperators and stuff.
08:14 PM MrHindsight: in the store they sell them as replacements for the solar garden lights
08:20 PM MrHindsight: in store they are the Westinghouse 18650
08:22 PM Tom_L: how do you recover a password if you can't log in?
08:22 PM MrHindsight: Linux?
08:23 PM Tom_L: it's some install on this disk i haven't used in a long time
08:23 PM Tom_L: yes
08:23 PM TurBoss: booting a livecd and chroot
08:23 PM Tom_L: wheezy i think
08:23 PM MrHindsight: yeah ^^
08:23 PM Tom_L: i'd sooner just write over it i think
08:23 PM MrHindsight: either way
08:24 PM Tom_L: http://www.linuxcnc.org/testing-stretch-rtpreempt/
08:24 PM Tom_L: probably try one of those
08:27 PM Tom_L: is the i386-r10 32bit? and amd64-r10 64 ?
08:45 PM ves: what the heck is the difference between a 7i92 and a 7i92M ?
08:53 PM Tom_L: the headers
09:03 PM MrHindsight: M sounds like male db25
09:03 PM MrHindsight: H has headers
09:03 PM MrHindsight: "blank" Female DB25
09:06 PM MrHindsight: pcw_home: just FYI people have been asking for the part number decoder ring
09:11 PM Crom: 7i92 being female...
09:15 PM Crom: damnbit... I should have bought the 7i92
09:16 PM Tom_L: start a collection
09:17 PM MrHindsight: I keep a supply of db25 M-M and F-F around
09:18 PM MrHindsight: also 26pin headers to db25 F cables
09:19 PM Tom_L: i build em as needed
09:23 PM Crom: now I have to find a 7i92 ABOB pin file
09:23 PM Crom: I have 6 fleabay BOBs, 1ea 7i76
09:24 PM Tom_L: pcw posted the name of one above
09:35 PM ves: mesa needs one 7i92 page, with order options for Male, Female, header grrrr
11:05 PM enleth: https://i.pinimg.com/originals/6b/99/43/6b99434c348ae798b74c9057a3789f35.jpg
11:06 PM enleth: not sure whether to call it creative or deranged
11:06 PM pink_vampire: OD grinder!
11:06 PM enleth: https://i.pinimg.com/originals/66/87/66/6687665b93a6a91fa2b1575c660a7114.jpg this at least has a little more... elegance to it
11:08 PM pink_vampire: how he index the chuck?
11:08 PM pink_vampire: enleth: ^
11:11 PM enleth: no idea, just found this one photo
11:11 PM enleth: I'd assume an indexing plate
11:12 PM pink_vampire: I need to find a way to power up the motor of my lathe
11:12 PM pink_vampire: it has 6 wires
11:14 PM enleth: 3-phase induction?
11:15 PM pink_vampire: it actually have 2 pair of 2 coils (so 4 coils)
11:17 PM pink_vampire: https://i.imgur.com/7ChR31t.jpg?1
11:18 PM pink_vampire: this is the wiring diagram for it
11:19 PM enleth: the shit is this
11:20 PM pink_vampire: i know!
11:20 PM enleth: uh
11:20 PM pink_vampire: it's a 2 speed motor
11:20 PM enleth: scrap the motor, fit a normal one?
11:21 PM pink_vampire: but i want the original!
11:21 PM enleth: but it was designed by a madman
11:23 PM enleth: OK, I think I see how this works
11:23 PM pink_vampire: but I want to keep it original
11:23 PM pink_vampire: it's a 1972 lathe
11:23 PM pink_vampire: made in Austria
11:24 PM pink_vampire: she is a blonde babe, I can't take the motor from her
11:24 PM pink_vampire: enleth: ^
11:25 PM enleth: I hate those damn switch position diagrams that look like an expressionist still painting of a plate of spaghetti
11:25 PM pink_vampire: me too
11:26 PM enleth: they could have just included a fucking truth table
11:26 PM pink_vampire: i never know if it's a NC or NO
11:26 PM enleth: but no, let the user trace a maze
11:26 PM pink_vampire: LOL
11:26 PM pink_vampire: one sec i will send you a picture
11:28 PM enleth: so it looks like U2 and U4 are running windings and W2 and W4 are starting windings?
11:29 PM enleth: pink_vampire: can you safely poke the motor terminals with multimeter probes while that thing is running?
11:30 PM pink_vampire: https://i.imgur.com/wspf3cq.jpg?1
11:30 PM pink_vampire: the "interface"
11:31 PM pink_vampire: https://i.imgur.com/ZXxKuwT.jpg?1
11:31 PM pink_vampire: what left from the switches
11:31 PM pink_vampire: this is how i got it
11:32 PM pink_vampire: i did a test with a multimeter
11:32 PM enleth: ok, so you can't run it because it's in pieces?
11:32 PM pink_vampire: i don't know
11:32 PM pink_vampire: the motor look ok inside
11:33 PM enleth: no, I mean, the switches and stuff are
11:34 PM pink_vampire: someone took it a part and never put it back, I don't know way, but this is why I probably got it
11:37 PM pink_vampire: this is the multimeter test
11:37 PM pink_vampire: https://i.imgur.com/hXULFlZ.jpg
11:38 PM pink_vampire: all the switches have missing parts
11:39 PM pink_vampire: enleth: ^
11:40 PM pink_vampire: https://i.imgur.com/zv12M4c.jpg
11:40 PM pink_vampire: this is the motor info + the coils
11:42 PM SpeedEvil: As a general point, it tends to be hard to kill motors with a couple of seconds test.
11:42 PM SpeedEvil: At least smaller ones.
11:43 PM SpeedEvil: If it buzzes angrily, that was not the right connection
11:44 PM pink_vampire: i can't even understand what the buttons do
11:44 PM pink_vampire: there is only some arrows
11:44 PM pink_vampire: https://i.imgur.com/ZXxKuwT.jpg?1
11:44 PM enleth: pink_vampire: that is actually rather obvious
11:45 PM pink_vampire: what is the large button?
11:45 PM enleth: switch to faster speed
11:46 PM pink_vampire: from left to right, maybe.. forward, reverse, stop, ????????, ???
11:47 PM enleth: forward, reverse, stop, slow/fast, vertical head feed
11:47 PM enleth: or vertical head spindle
11:47 PM enleth: more like spindle?
11:47 PM pink_vampire: where did you find the info??
11:48 PM enleth: nowhere, I just looked at the photos
11:50 PM pink_vampire: how the switch is get connected? the right pin the left one? or the upper to the lower?
11:51 PM enleth: I'm pretty sure they're paired horizontally
11:51 PM enleth: the first two are double-deckers
11:52 PM enleth: engaging left/right always connects V2,4 to R
11:53 PM enleth: Z2,4 is S for left, R for right
11:53 PM pink_vampire: on the off position the top is engage?
11:55 PM enleth: the diagram would be WAY more readable if it didn't include the vertical head motor
11:59 PM pink_vampire: i steel can't understand how it work
11:59 PM pink_vampire: how it make it slower?
