12:49 AM IchGucksLive: hi all
12:52 AM IchGucksLive: its getting the record breking head today in mai her in germany
12:52 AM fragalot: went from 35°C yesterday to 15°C now
12:54 AM IchGucksLive: fragalot, here tomorrow
01:51 AM Deejay: moin
02:06 AM gloops: i think its time for a new chopsaw
05:14 AM jthornton: morning
05:14 AM XXCoder: hey jt
05:29 AM Tom_L: morning
05:31 AM jthornton: .weather
05:31 AM theCockerel: Yahoo! Weather - Poplar Bluff, MO, US: Mostly Cloudy, 20°C (68°F), Humidity: 78%, Gentle breeze 4.9m/s (↑)
05:34 AM jthornton: dang can't find my pi
05:35 AM XXCoder: lol https://www.technologyreview.com/s/611072/ai-generates-new-doom-levels-for-humans-to-play/
05:37 AM jthornton: I used to play Doom a lot with a buddy over the phone
05:38 AM XXCoder: heh I played with editing maps, but never really got far on that
05:39 AM XXCoder: wolfenstein level editor was easier to do, and heck of a lot of fun
05:40 AM XXCoder: got new employee in company apparently, "Test EmployeeHuman Resources Administrative Assistant "
05:41 AM XXCoder: started today
05:41 AM jthornton: yea HR got more people now what do they do
05:42 AM XXCoder: better dept budget!
08:23 AM JT-Shop: just when I thought I could do fun stuff today a po from Briggs shows up
08:33 AM skunkworks: Yay! Awww...
08:37 AM JT-Shop: just some small parts they won't take long
08:55 AM skunkworks: briggs and scrap iron..
08:56 AM skunkworks: dad used to bring home lots of them from the junk yard.. Made a lot of good running engines out of junk
09:05 AM devlap: hey guys. got some new stepper drivers. My old where set to Peak 3.5A 1.8A RMS in "Half Current" mode.
09:05 AM devlap: Whats the equivalent on the TB6600
09:06 AM devlap: For the dips
09:10 AM alex_joni: https://www.makerlab-electronics.com/my_uploads/2017/05/TB6600-Stepper-Motor-Driver-01.jpg
09:11 AM alex_joni: I'd try 1.5 maybe 2.0A see if the motors don't get too hot
09:11 AM alex_joni: 1.8A to 3.5A peak seems silly
09:19 AM IchGucksLive: hi all
09:21 AM devlap: Hey Ich
09:22 AM devlap: I got my TB6600. I was running the dips on the old driver at "3.5A PEAK 1.8 RMS" but also "Half Current" dip. Whats good to set the TB6600 to?
09:23 AM devlap: I'm guessing 1.5ish. thats what alex_joni mentioned too.
09:23 AM IchGucksLive: hi devlap MAKE shure all Signal voltige is down bevor a dip change
09:24 AM IchGucksLive: devlap, best also parport disconnect
09:24 AM IchGucksLive: devlap, YOU already lost 2 Drivers
09:24 AM devlap: its all off
09:24 AM IchGucksLive: ok then go for 800steps/rev
09:24 AM devlap: Its never on when I work on it.
09:24 AM devlap: I set 800 already.
09:25 AM IchGucksLive: i woudt start at 2.8A
09:25 AM IchGucksLive: Do you got a image what Tb6600 are deliverd
09:25 AM IchGucksLive: 2A 2B version
09:25 AM devlap: https://www.makerlab-electronics.com/my_uploads/2017/05/TB6600-Stepper-Motor-Driver-01.jpg looks like this
09:26 AM devlap: whats the difference
09:26 AM IchGucksLive: the stepway inside
09:27 AM IchGucksLive: devlap, go vor 2.8A
09:27 AM IchGucksLive: devlap, what Volt is the PSU
09:28 AM IchGucksLive: 36Best to go
09:28 AM devlap: 24
09:28 AM IchGucksLive: get yourself a bigger one AFTER you change all the drivers
09:29 AM IchGucksLive: so then Repower the SYSTEM
09:29 AM IchGucksLive: Go to STEPCONF
09:30 AM IchGucksLive: you said Y/Z axis got the Ballbearing 5mm pitch
09:30 AM devlap: yea I think so
09:30 AM devlap: calibration will let me know pretty quick
09:30 AM IchGucksLive: go forward to the Y Axis side
09:31 AM lcvette: morning all
09:31 AM IchGucksLive: hi IchGucksLive
09:31 AM IchGucksLive: hi lcvette
09:31 AM IchGucksLive: devlap, use 200 / 4 1:1
09:31 AM lcvette: hi IchGucksLive
09:32 AM IchGucksLive: devlap, use 30mm/sec VEL
09:32 AM IchGucksLive: and go for 150 Aceleration
09:32 AM IchGucksLive: POWER the Driver Tb6600
09:32 AM lcvette: whoa... this looks like the conversation i came for
09:32 AM lcvette: kinda
09:32 AM IchGucksLive: lcvette, im in germany
09:32 AM IchGucksLive: devlap, HIT TEST AXIS
09:33 AM lcvette: then good evening!
09:33 AM lcvette: lol
09:33 AM lcvette: US here
09:33 AM IchGucksLive: go for Green arrows left right middle of the AXIS or 100mm from side
09:33 AM IchGucksLive: devlap, the fild below saying +-
09:34 AM IchGucksLive: devlap, the number on go for 30mm
09:34 AM IchGucksLive: hit the Button next
09:34 AM IchGucksLive: mashine shoudt move
09:34 AM IchGucksLive: back and forth
09:34 AM IchGucksLive: NO STALL
09:35 AM IchGucksLive: increse within 2 cy<cles Movement ACC from 150 to 250 increse by 25
09:35 AM IchGucksLive: devlap, if we can go that HARD
09:35 AM IchGucksLive: NO Stall
09:36 AM IchGucksLive: devlap, go Back to 200
09:36 AM IchGucksLive: devlap, increse VEL by 5
09:36 AM IchGucksLive: wait 4 cycle moves
09:37 AM IchGucksLive: devlap, increse till we reatch 50 or seeing stall
09:37 AM IchGucksLive: shoudt happen within this numbers at 24Volt
09:37 AM IchGucksLive: lcvette, NOW to you
09:37 AM IchGucksLive: whats up
09:37 AM IchGucksLive: lcvette, a Build or a setup
09:38 AM lcvette: lol
09:38 AM lcvette: i finished my build im trying to do my first setup
09:39 AM lcvette: im a bit confused on the motor numbers
09:39 AM lcvette: mi using a 7i92_7i77_7i76
09:39 AM IchGucksLive: lcvette, my YT channel https://www.youtube.com/channel/UCmwhCL92ZQRSVqFe3jGwJSQ/videos?disable_polymer=1
09:39 AM lcvette: I have a friend running exact same machine with exact same motors and drives
09:40 AM IchGucksLive: lcvette, motors rated
09:40 AM IchGucksLive: 3Nm
09:41 AM IchGucksLive: 570oz
09:41 AM IchGucksLive: Nema 24
09:41 AM IchGucksLive: Drivers names DM D542 ...
09:41 AM IchGucksLive: DQ ;---)))
09:43 AM IchGucksLive: I Got a Firer Prepare Alarm i n eed to take action be ack in 1hr +
09:56 AM skunkworks: lcvette: use mousepad to open your ini/hal files. not libre office. libre could add formatting to the file that should be just pure text
09:57 AM lcvette: im using notepad++
09:58 AM devlap: Ok. Let me wire it all up and ill report back
09:58 AM lcvette: i learned how to use the replace all function to change the hm2_pci to hm2_eth and hm2_5i25 to hm2_7i92
09:58 AM lcvette: im learning
09:58 AM skunkworks: cool!
09:58 AM lcvette: I have my buddies config files that work on his identical machine but with some different connection points and his is metric and mine is in inches
09:58 AM skunkworks: have you tried the config yet?
09:59 AM lcvette: so im trying to decipher how to best approach
09:59 AM lcvette: tried it?
09:59 AM skunkworks: the config
09:59 AM lcvette: no need to change a few things first
09:59 AM lcvette: thatsd what im trying to learn how to do now
09:59 AM lcvette: is change the motor settings from metric to inches
10:00 AM lcvette: and go through and change any input and output locations that differ from his machine to mine
10:00 AM lcvette: we have all the same items just wired to different pins
10:00 AM lcvette: wish i had had his pinout when i did all that
10:01 AM lcvette: would have simplified things
10:02 AM skunkworks: it is good to have an understanding of hal/ini. this is a great exersize
10:03 AM lcvette: certainly getting into it
10:03 AM lcvette: things are making more sense.. not what is going on, but what people discuss i see it now and it makes more sense
10:05 AM lcvette: #******************** # Axis X #******************** [AXIS_0] TYPE = LINEAR HOME = 0.0 FERROR = 0.1 MIN_FERROR = 0.01 MAX_VELOCITY = 280 MAX_ACCELERATION = 2000.0 # The values below should be 25% larger than MAX_VELOCITY and MAX_ACCELERATION # If using BACKLASH compensation STEPGEN_MAXACCEL should be 100% larger. STEPGEN_MAXVEL = 350 STEPGEN_MAXACCEL = 4000 P = 3000 I = 0 D = 0 FF0 = 0 FF1 = 1 FF2 = 0 BIAS = 0 DEADBAND = 0 MAX_OU
10:05 AM lcvette: alot of these numbers don't make sense to me
10:06 AM skunkworks: those do look metricy
10:07 AM lcvette: yeah
10:07 AM lcvette: and odd
10:07 AM lcvette: and i have no reference to compare to
10:07 AM lcvette: what normal inch would look like on a similar machine
10:07 AM skunkworks: they are in units per second.. So - 280 max vel is 280mm/s
10:07 AM lcvette: ahhhhhh
10:08 AM skunkworks: you want in/s
10:08 AM lcvette: that makes more sense
10:08 AM lcvette: ok now i can work with numbers i know!!
10:09 AM skunkworks: you want then 11 for max velocity. Wow - 660 ipm
10:09 AM lcvette: supposed to be 709
10:10 AM lcvette: 6mm lead, 300rpm servo
10:10 AM lcvette: 3000rpm
10:10 AM lcvette: linear rail vmc
10:10 AM JT-Shop: well the hard part is done all the blanks are machined to size
10:13 AM lcvette: Nice JT-Shop!
10:14 AM lcvette: skunkworks: do you know if the other numbers are also in mm/sec
10:14 AM lcvette: MAX_ACCELERATION = 2000.0
10:14 AM lcvette: STEPGEN_MAXVEL = 350
10:15 AM lcvette: STEPGEN_MAXACCEL = 4000
10:20 AM skunkworks: well - mm/s^2 for acceleration
10:21 AM gloops: 2000 seems very high for accleration?
10:22 AM gloops: 120m/min?
10:23 AM gloops: im in mm my acceleration is 20
10:28 AM lcvette: is is?
10:29 AM lcvette: what type machine?
10:29 AM skunkworks: 80in/s^2..
10:29 AM gloops: a router, stepper motors
10:29 AM skunkworks: that is pretty smoking
10:29 AM lcvette: it looks fast in the videos
10:29 AM alex_joni: big drives
10:29 AM skunkworks: but if the drives can handle it. The thing must thump the floor when machinin
10:30 AM gloops: whats the video?
10:34 AM lcvette: um hang on i will fetch some vids
10:37 AM lcvette: https://www.youtube.com/watch?v=EnseKvFn5Ik
10:37 AM lcvette: there is one of it tapping where you can see the rapids in between tap cycles
10:38 AM lcvette: https://www.youtube.com/watch?v=ewQnvx73wDY
10:39 AM lcvette: here is one of it making a small test part when we were trying to figure out the spindle servo settings
10:39 AM lcvette: its musch better now
10:39 AM lcvette: forgive the rattling noise, the head cover was not fully tightened down and was vibrating a horrible racket in that one
10:42 AM Tom_L: what does it mean: hm2/hm2_7i90.1: error reading hm2 cookie ?
10:47 AM JT-Shop: Op 1 done 90 seconds part to part
10:49 AM pcw_home: Tom_L thats due to a bug in the current hm2_7i90 driver
10:49 AM Tom_L: ignore it?
10:49 AM Tom_L: i don't recall getting that error before
10:49 AM pcw_home: you can work around is by setting the ioaddress
10:49 AM pcw_home: around it
10:49 AM Tom_L: ok
10:49 AM Tom_L: it seemed to work ok
10:50 AM Tom_L: just never noticed that error on startup
10:50 AM Tom_L: i was updating the config to test the 7i80 is when i first noticed it
10:51 AM pcw_home: its new... the issue is that if you dont supply the ioaddress it searches at 0x378 (and usually finds the 7i90 there) then tries the next default address at 0x278 and fails
10:52 AM Tom_L: right
10:52 AM Tom_L: i guess that makes sense since i did an update the other day
10:53 AM pcw_home: the bug is really this: if its going to probe default addresses for 7I90s it should suppress any error messages
10:54 AM pcw_home: only if it finds no cards should it belly-ache about it
10:54 AM Tom_L: do hm2 drivers ignore parameters not belonging to them? by that i mean can i set BOARD_IP= to somthing and leave it if i'm using a 7i90?
10:54 AM pcw_home: I think it will complain
10:54 AM Tom_L: ok
10:54 AM Tom_L: at first that's what i thought the error might be..
10:55 AM Tom_L: but it didn't change when i commented that part out
10:55 AM pcw_home: no that a known issue with the 7I43/7I90 drivers in 2.7.12+
10:56 AM Tom_L: does 2.7.13 change it?
10:56 AM Tom_L: nm, you said 12+
10:56 AM pcw_home: I think its still broken
10:56 AM pcw_home: setting the ioaddr token fixes it
11:00 AM lcvette: while the gurus are in here, quick question while im editing in my config file...
11:00 AM lcvette: net atc-fwd hm2_7i92.0.7i76.0.3.output-05 <= motion.digital-out-03
11:01 AM lcvette: in that statement, the hm2_7i92.0.7i76.0.3.output-05 does the 7i76.0.3 the last .0.3 change ever when designating I/Os for the 7i76?
11:02 AM lcvette: I'm editing a config file without a comparable config file and not certain if there are different designators for say the TB5 and TB6 rows or something like that and that is what those secondary ,0.3 numbers mean
11:06 AM Tom_L: pcw_home how do you interrogate the parports in linux? i'm not sure which is the first.. i assume 0x378 is
11:08 AM pcw_home: pretty sure the 7I90 driver looks at only 0x378 and 0x278 (0x3BC would be the next one but I dont think it checks)
11:09 AM Tom_L: so ioaddr=0x378 ? enter as a hex value?
11:09 AM pcw_home: yes, hex (man hm2_7i90)
11:09 AM Tom_L: i'm looking at it right now
11:09 AM gloops: that does look fast lcvette
11:10 AM Tom_L: well, the html docs anyway
11:11 AM pcw_home: the manual page has an error (no config token on example line)
11:11 AM Deejay: re
11:12 AM gloops: only the first mill like that i googled - rapid speed 3000mm/mm
11:15 AM gloops: which reminds me, since i cured the ground issue on my thing, i never tested top speed again
11:16 AM Tom_L: ok that was an easy fix
11:18 AM pcw_home: lcvette: the 7i76.0.3 means 7I76 connected via sserial port 0 channel 3. This will not change unless you change firmware
11:19 AM pcw_home: with a 7I77,7I76 config the sserial port arrangement is normally
11:19 AM pcw_home: 0.0
11:19 AM pcw_home: 0.0 = 7i77 field I/O
11:19 AM pcw_home: 0.1 = 7i77 analog
11:19 AM pcw_home: 0.2 = 7i77 expansion
11:20 AM pcw_home: 0.3 = 7i76 field I/O
11:20 AM pcw_home: 0.4 = 7i76 expansion
11:21 AM pcw_home: a 7I76_7I77 config would put the 7I76 first
11:30 AM IchGucksLive: hi
11:30 AM IchGucksLive: gloops, he is making a ultrasonic router with that numbers on 24V
11:33 AM MarcelineVQ: gloops: what was the grounding solution in the end?
11:34 AM gregcnc_: what do you machine with ultrasound?
11:42 AM Tom_L: http://www.engineeringarticles.org/ultrasonic-machining-process-working-principles-advantages/
11:44 AM gloops: MarcelineVQ 3 inch piece of wire from BOB to cabinet
11:44 AM gloops: grounded the BOB pccGnd
11:45 AM lcvette: awesome, exactly what i was looking for PCW!!
11:45 AM lcvette: thank you!!
11:46 AM IchGucksLive: gloops, a EM Capaciter will also do a better job
11:46 AM gloops: Ichs yeah hear a few solutions, for the time being a bit of wire works heh
11:46 AM IchGucksLive: lcvette, 4800mm/min is a real good vmc
11:47 AM IchGucksLive: lcvette, that is 80 in VEL and with 450 in ACC you are in business
11:47 AM IchGucksLive: pcw_home, on ?
11:49 AM pcw_home: yeah
11:50 AM IchGucksLive: hi pcw_home as we speek of yesterday the first 5i25 came back rev1 with a upcoming com13
11:51 AM IchGucksLive: i did this morning a full ram change the Cmos bat change and a full 10.04 ISO backup DD parition
11:51 AM IchGucksLive: partition rewrite
11:51 AM IchGucksLive: and it has gone
11:52 AM pcw_home: not sure I understand
11:52 AM IchGucksLive: itas a refuing event after year so i guess it is more the PC then the 5i25 that troubles up
11:53 AM IchGucksLive: pcw_home, you may remember that im fighting on plasmas since years with communication 13
11:53 AM IchGucksLive: 5i25 7i76
11:54 AM IchGucksLive: i updated 2 times firmware to the 5i25 on your request not so this morning
11:55 AM IchGucksLive: gloops, did bring me within the last posts to GND all 12V 5V 24V
11:55 AM IchGucksLive: and do also put EM capacitors within the main clamp rowsa
12:06 PM lcvette: IchGucksLive, where did that speed come from? 4800mm/min?
12:06 PM IchGucksLive: HAAS
12:07 PM IchGucksLive: lcvette, it is by far not the end it is a start point
12:07 PM IchGucksLive: you may reach 160 750
12:07 PM lcvette: oh
12:07 PM lcvette: i see
12:07 PM IchGucksLive: lcvette, this will harvest your mashine rails and breks
12:08 PM lcvette: machine is "capable" of much faster
12:08 PM IchGucksLive: lcvette, at your mashine size it will be a good setup also
12:08 PM lcvette: servos and drive with screws and rails will go the rated speed no problem which is 709ipm
12:09 PM IchGucksLive: lcvette, but keep in mind it is the max that ruins the budget
12:09 PM lcvette: or 18000mm/min
12:10 PM IchGucksLive: yes 275 VEL is a industrial standard
12:10 PM IchGucksLive: but not needed in hobby retrofits
12:11 PM IchGucksLive: you wont like loosing your vfc in 3 years time only by G0 movese
12:11 PM IchGucksLive: the 160 VEL will do the job as long as you live on earth
12:12 PM IchGucksLive: BUT it is your money that is invested
12:13 PM lcvette: i gotcha
12:13 PM IchGucksLive: lcvette, if you can make in 3 years money to get a new DMU 60 and resell the retrofit for 50% of invest go for it
12:14 PM lcvette: right now, the config file is all im worried about..lol
12:14 PM lcvette: at my pace, in 3 years I'll just be finishing it
12:15 PM IchGucksLive: lcvette, we are all here to worry eith you
12:15 PM IchGucksLive: lcvette, working on config mean movement soon
12:15 PM lcvette: sudo apt-get install slowpoke mode
12:15 PM CaptHindsight: https://imgur.com/a/4NcMC someone was showing off their first cnc glue gun project
12:16 PM IchGucksLive: ok im off BYE Gn8 from Germany
12:17 PM lcvette: question on home/limit switches
12:18 PM lcvette: can I share a home/limit switch on one end and jumper the signal to two inputs for the x home and x min for example? is that an acceptable situation?
12:18 PM lcvette: or do i need to use 3 switches per axis?
12:19 PM fragalot: Harroh
12:20 PM Rab: CaptHindsight, mock if you will, but that rack probably has a heroic edge in rigidity over the typical 3D printer frame.
12:20 PM fragalot: the prints are probably just as crisp as those pictures
12:21 PM Rab: haha
12:22 PM Rab: I can only identify one motion axis, not sure what else is going on.
12:22 PM gloops: lcvette use soft limits and 1 switch
12:23 PM fragalot: I believe the Z axis is a rack&pinion style piston
12:23 PM fragalot: that moves along X
12:24 PM fragalot: lcvette: you can configure linuxcnc to use the same switch for limit and home.
12:24 PM fragalot: no need to jumper
12:24 PM CaptHindsight: I had to shield my eyes
12:24 PM Rab: I see it now. Like a linear actuator for leveling RVs.
12:25 PM fragalot: CaptHindsight: but it has a storage drawer!
12:25 PM CaptHindsight: you can only stare so long into the arc before you suffer
12:25 PM fragalot: where you can keep the manual
12:33 PM * hazzy-dev finally got the corolla fixed!
12:33 PM hazzy-dev: Before: https://i.imgur.com/oSji6r4l.png
12:33 PM hazzy-dev: After: https://i.imgur.com/vKp468tl.png
12:36 PM fragalot: you forgot to put the logo back :P
12:36 PM fragalot: and the reveal on the bonnet isn't quite there yet; otherwise great work!
12:36 PM MarcelineVQ: did a sewer crocodile pop out of a manhole and chomp that corner?
12:37 PM devlap: What are default settings for the A axis? I put in some accel and velocity but its not turning. My stepper shaft has a 3:1 ratio with a pulley to a three jaw.
12:37 PM CaptHindsight: devlap: first time moving the motor for that axis? or did it work until recently
12:38 PM devlap: I never have used the A axis. I just replaced all my stepper drivers.
12:38 PM devlap: xyz worked and did before
12:38 PM devlap: A never tried.
12:38 PM CaptHindsight: OK so first try and it's not spinning
12:38 PM CaptHindsight: is all the wiring correct?
12:39 PM devlap: It matches the other axis.
12:39 PM CaptHindsight: can you easily turn the stepper shaft with your hand?
12:39 PM CaptHindsight: or does it fight you?
12:40 PM devlap: theres more resistance than the other axis, but it does turn
12:40 PM devlap: The other axis drive screws, this pulley arrangement might be a little tighter
12:41 PM CaptHindsight: often it's a wiring problem, STEP and DIR reversed or no power connected or similar
12:42 PM CaptHindsight: so just a 3:1 pulley to a chuck on a bearing?
12:42 PM devlap: yea
12:43 PM CaptHindsight: which stepper drive are you using?
12:43 PM devlap: TB6600
12:45 PM CaptHindsight: are the control signals from a parallel port BOB?
12:45 PM devlap: yes/
12:48 PM devlap: you know what
12:48 PM devlap: I got it.
12:48 PM devlap: Inverting the A signal pins in stepconf.
12:48 PM devlap: Now whats a good speed
12:48 PM CaptHindsight: common problem
12:50 PM fragalot: devlap: fast enough to make you happy, but slow enough for it to be reliable. :P
12:50 PM devlap: hah whats a good starting point
12:51 PM fragalot: Four. ?
12:51 PM devlap: 4deg/s
12:51 PM * fragalot has no idea if that's not obvious already :)
12:52 PM devlap: what abut the Pulleyteeth motor:leadscrew and leadscrew pitch
12:53 PM fragalot: skip that in the wizard and change it manually in the configuration file it spits out
12:53 PM fragalot: you want it in steps/degree
12:53 PM fragalot: so a 200 steps/rev motor * 3:1 pulley = 600 steps/rev; = 600/360 steps/degree
12:54 PM fragalot: adjust for your numbers
12:54 PM CaptHindsight: you elitists with your maths
12:55 PM devlap: where is that setting in the config file
12:55 PM fragalot: occupational hazard, CaptHindsight
12:55 PM fragalot: devlap: where you would normally enter the steps/unit
12:58 PM devlap: I'm not seeing steps or something like that anywhere
12:59 PM hazzy-dev: fragalot: The frame is pretty badly bent up, so it was really hard to get it looking decent at all
12:59 PM hazzy-dev: The radiator won't even fit in the original location, had to move it back a few inches
01:00 PM gloops: SCALE
01:00 PM lcvette: fragalot, what would sharing a switch for home and limits look like?
01:01 PM lcvette: # ---setup home / limit switch signals--- net home-x => axis.0.home-sw-in net min-x => axis.0.neg-lim-sw-in net max-x => axis.0.pos-lim-sw-in
01:02 PM lcvette: thats what is currently in the config file
01:02 PM devlap: scale for my other axis are 160, that doesnt seem right gloops
01:02 PM gloops: well, tested at 4000mm/min, 5mm cut in pine, no problems, thats enough testing i think
01:02 PM fragalot: lcvette: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Homing_And_Limit_Switch
01:02 PM fragalot: gloops: have you gotten any pictures made yet?
01:03 PM gloops: no not of the machine
01:03 PM gloops: i should get more time with it soon, its going to work
01:03 PM gloops: as in - made to do stuff, not operate correctly
01:04 PM devlap: So I have 800steps/rev on x/y/z why is scale 160
01:05 PM gloops: scale = steps per UNIT
01:05 PM devlap: 160/mm
01:06 PM gloops: your screw is 5mm pitch
01:06 PM devlap: Sounds good.
01:06 PM gloops: 1 rotation of the motor turns the screw which makes travel of 5mm
01:07 PM devlap: so 6 steps/degree
01:07 PM gloops: no
01:07 PM devlap: (800 * 3)/360
01:08 PM gloops: oh you got pulleys right
01:08 PM gregcnc_: is this a linear or rotary axis?
01:08 PM devlap: well 6.6/
01:08 PM devlap: rotary
01:09 PM gloops: so lets take the resolution of that
01:09 PM CaptHindsight: anyone have success using multiple bluetooth transceivers for data logging?
01:10 PM CaptHindsight: say 8 in the same room, short range <10m
01:10 PM Loetmichel: *HIHIHI* coworker asked me today at lunch if i could help him changing the H7 headlight bulb on his C-max... (Sure!) and if thats bad if the "oil" light comes on when braking hard... (YES!!!!111oneeleven) Boss dry as fu**: "nope, you can safely drive another 40'000km with the oil light on... when changing the bulb i found a card:" last oil change at 86000km, next to be at 106000" the car now
01:10 PM Loetmichel: has 146000km on the odometer... and the coworker never looked after the oil. had to put in 2.5 liters 5W30 to get it to register again on the Dipstick at all... MAAAN some car drivers are naive... ;)
01:11 PM gloops: a 60mm diameter cylinder has circumference of 188mm
01:13 PM gloops: 1 step = .08mm
01:13 PM gregcnc_: what?!
01:13 PM gloops: i think youll find thats right
01:13 PM devlap: thats 3 thou
01:15 PM gloops: wood or metal cutting?
01:15 PM devlap: Its for metal. I mainly use it to do pcbs.
01:16 PM devlap: I can microstep higher
01:16 PM gloops: rotary pcbs? but anyway you can increase microstepping if need be
01:16 PM devlap: Haha no I don't rotary pcbs, thats why the A axis is as of yet unused.
01:16 PM devlap: I dunno what people would use the rotary for on an engraver like this.
01:17 PM CaptHindsight: Loetmichel: many of the cars sold to junk yards for $300 have codes that are easily fixed for <$300
01:17 PM CaptHindsight: other just buy used cars and drive them onto the ground with never have added any oils or fluids
01:17 PM gloops: rotary axis is very versatile, i will build one
01:17 PM CaptHindsight: onto/into
01:18 PM gloops: 1 mm length by 300mm swing
01:18 PM Rab: devlap, live drag knife?
01:18 PM gloops: bbiab
01:19 PM devlap: I've seen peopple do wood sculptures.
01:19 PM devlap: hehehe.
01:19 PM devlap: I've got no imagination I suppose.
01:19 PM gregcnc_: axis TYPE should be set to ANGULAR for rotary
01:19 PM devlap: yea mine is.
01:19 PM gregcnc_: what are you measuring in mm?
01:20 PM gregcnc_: did you figure out the scale?
01:20 PM devlap: Everything?
01:20 PM devlap: uhh.
01:20 PM devlap: 6.66?
01:22 PM devlap: some guy engraved a mic dial thats pretty coo.
01:25 PM Loetmichel: CaptHindsight: the best: he asked me if he couldnt wait with the refill until next month when the car goes to a checkup with oilchange. He didnt want to "waste" 2 liters of "expensive" oil (mineral 5W50, cheapset stuff aviable from a discounter) for those 4 weeks.
01:25 PM CaptHindsight: sounds familiar
01:26 PM Loetmichel: and he has 2*80km commute every workday
01:26 PM CaptHindsight: save $2 and risk >$3000 for a new engine
01:26 PM Loetmichel: more like €5000
01:26 PM Loetmichel: german mechanics are EXPENSIVE
01:28 PM gregcnc_: 6.66 will be 16 steps short on a 360° move if it matters, consider changing angular units to grad to make SCALE a nice round 6
01:45 PM hazzy-dev: I'm a little worried about my brother, he cleaned the shop, very uncharacteristic: https://i.imgur.com/3qperUUl.png
01:45 PM hazzy-dev: Can you find and identify the haas? It's hiding ...
01:46 PM hazzy-dev: Opps, that was a tiny pic, this is better: https://i.imgur.com/3qperUU.png
01:48 PM Spirit532 is now known as Guest34186
01:58 PM miss0r: Can anyone in here help me track down the pin-out for the mitutoyo glass scale cable? It has the following part number: 09AAA030C(7m). In one end it has a two row 15 pin sub-D in the other end it has a round din plug of some sorts. This cable was caught up on a moving machine and the cable was ripped out of the circular plug, leaving nothing but a few strands of copper to go one. If anyone of you have a simular
01:58 PM miss0r: cable with you, I would love to hear from you.
01:58 PM * fragalot returns!
01:59 PM miss0r: :D
02:01 PM fragalot: miss0r: have you got a picture of said cable?
02:02 PM miss0r: I can take one. What would you like to see?
02:02 PM fragalot: the connectors
02:02 PM miss0r: Its armored.. looks nasty...
02:02 PM miss0r: alright, 2 sec
02:04 PM miss0r: https://imgur.com/a/jPMV2xL
02:06 PM miss0r: fragalot: ^
02:06 PM * fragalot does his magic on the gargler
02:10 PM miss0r: I have found the pinout for the 15-pin sub-d.
02:10 PM miss0r: But that end isn't even broken lol
02:11 PM miss0r: I may have it here...
02:11 PM miss0r: https://www.mitutoyo.co.jp/eng/support/service/catalog/07/E13005.pdf
02:14 PM fragalot: I'm going through that one as well but couldn't find an 8pin one
02:15 PM fragalot: well, not for encoders anyway.. I'm assuming that connector isn't M12?
02:16 PM miss0r: more like 14mm
02:20 PM fragalot: do you know what scale / DRO it came off of?
02:22 PM miss0r: Acording to the replacement parts list it is either an AT102, 103, 111, 112 or 181
02:25 PM miss0r: On page 28 of this: https://www.mitutoyo.com/wp-content/uploads/2018/01/DROsystem_2217.pdf I have the correct pinout for the 15-pin sub-d, it would seem
02:26 PM fragalot: part of me is wondering if that cable you've got is an active one that convers the secret sauce signal in the read head to a standard one
02:27 PM miss0r: Nope. its completely benign
02:27 PM miss0r: I would even have had a replacement one, had I not cut off the circular connector a long time ago and threw it out, to use the rest of the cable as an extention cord... >.<
02:27 PM fragalot: lol
02:28 PM miss0r: How was I to know they would ram the mill with a portable crane!
02:28 PM fragalot: it's to be expected :P
02:28 PM miss0r: yeah well... You can't win'em all :]
02:31 PM miss0r: damnit! I would be the hero of the day, if i could repair this one, and they wouldn't have to wait for a new one
02:33 PM fragalot: do they not have another scale that is still intact?
02:35 PM gloops: whats would you can an axis, that is like the spindle rotating under control?
02:35 PM gloops: as in, control the angle of the cutter
02:35 PM fragalot: gloops: try that first question again
02:35 PM gloops: drag knife say
02:36 PM miss0r: fragalot: Sadly I do not. The other scale on the installation does not have the circular plug in the end. That reader head has the cable premounted
02:36 PM Rab: gloops, like a spindle with encoder for rigid tapping?
02:36 PM gloops: ok , say you want a plotter to draw calligraphy, you know with a broad tip pen, and you want the pen to move round to create the letter strokes
02:37 PM gloops: Rab if thats what happens during rigid tapping, yes
02:38 PM miss0r: fragalot: looking at drawings, it is most likely an AT102
02:38 PM fragalot: miss0r: i've just sent an email to a mitutoyo distributor saying "plshalpmymachineisdown"
02:38 PM gloops: this is the persons question from facebook -
02:38 PM miss0r: Excellent
02:38 PM gloops: Nutball question here... has anyone seen a biggish-scale 3d printer with an extruder tip that, rather than being round, is chisel-style like a calligraphy pen, and has some kind of swivel method to turn 90 degrees about the centerline of the extruder?
02:39 PM fragalot: gloops: Yes.
02:39 PM miss0r: fragalot: So you have an expert on hold, waiting to write you back _right_now_? and not with the standard 14-97 days of waiting?
02:39 PM gloops: fragalot what would that machine be called?
02:40 PM fragalot: gloops: there is even a research project at a local uni here where they use the rotation of the nozzle to "mix" the plastic as it's being extruded.
02:40 PM gloops: or the extruder mechanism
02:40 PM fragalot: miss0r: Well it's an email, but it's flagged as "urgent"?
02:40 PM gregcnc_: it's just a rotary axis. making it work would be up to giving it a proper program
02:41 PM miss0r: so, theres a chance they will only spend 8 days answering :D if i can't figure out how to fix it tonight, I'll need to order a new one asap
02:41 PM fragalot: Aye
02:41 PM fragalot: I'll let you know if I get something within the hour
02:41 PM fragalot: if not - .. well your suppliers are shut for today now anyway :P
02:42 PM devlap: gregcnc_, re engular units and grad, how does that work?
02:42 PM miss0r: fragalot: RS even has the DRO for sale still :D https://uk.rs-online.com/web/p/linear-counters/7959940/
02:43 PM fragalot: is there anything they don't have?
02:43 PM gregcnc_: devlap http://linuxcnc.org/docs/2.7/html/config/ini-config.html#_traj_section
02:43 PM miss0r: I haven't had any luck ordering fresh milk...
02:43 PM gloops: yes gregcnc not much doubt its doable
02:45 PM miss0r: fragalot: and tomorrow is a hollyday
02:45 PM devlap: Ok set to grad.
02:45 PM devlap: Whats a good started speed for vel/accel on a rotary axis?
02:46 PM fragalot: miss0r: and some places (like mine) are going to close on friday too because of reasons
02:47 PM devlap: I guess I should calculate the steps at velocity on X and translate that to grad
02:49 PM gloops: i can see youre beginning to use your own brain devlap
02:50 PM miss0r: fragalot: It seems I can order a new one from texas, and have it here within 2-4 days
02:50 PM fragalot: do that then
02:51 PM miss0r: I want it to workie workie the day after tomorrow :D
02:51 PM fragalot: order it anyway :P
02:51 PM fragalot: you can always use it as an extension cable
02:52 PM miss0r: Bleh :DF
02:53 PM devlap: gloops, my brain works wayyy better when it gets sleep. which wasn't this week.
02:54 PM lcvette_: i'm trying to run through setting up the servo drives and motor setup in pncconf and just wrestling with what im seeing
02:54 PM gloops: well i know how you feel devlap, my mrs is a heavy snorer
02:55 PM lcvette_: i know the formulaw to calculate the gear ratio in the drive
02:55 PM devlap: I have a 6mo and he has a fever, and he sleeps with the mrs snorer but she was up half the night about the fever, and sleeping half the night like a chainsaw cutting aluminum siding
02:55 PM miss0r: I'll call it a night, see you around
02:55 PM lcvette_: but im not having much luck getting the numbers entered to match in pnc conf
02:57 PM devlap: so my x scale is 160 and 40 max velocity, so thats 160 steps a unit, 40 units/s max movement, so thats 6400 steps a second movement. 6400 / 6 grads = lets call it 1000 rad/s
02:57 PM devlap: grad*
02:57 PM devlap: sounds fast.
02:58 PM gloops: hmm, depends on milling strategy i suppose
02:59 PM gloops: you dont need great rotary speeds for indexing
02:59 PM fragalot: cya miss0r .. If they ever get back to me i'll forward you the mail
02:59 PM devlap: No, lets see how fast she will chooch
03:00 PM devlap: so in the linuxcnc app under manual control, my A axis moves in mm units weird
03:02 PM lcvette_: my servo drive manual is giving me my exat machine example
03:02 PM lcvette_: 6mm ballscrew
03:03 PM gregcnc_: lcvette, what specifically isn't working out?
03:03 PM lcvette_: 6mm/.001mm=6000 pulses per revolution
03:04 PM lcvette_: in pncconfig
03:04 PM lcvette_: i can only enter up to 1000 motor steps per rev
03:05 PM lcvette_: but then i saw i can use the microstep multiplication factor
03:05 PM lcvette_: so i put 6 there
03:06 PM lcvette_: problem is when i enter my encoder information everything gets whacky in max motor speed
03:06 PM gregcnc_: best to edit .ini using math
03:06 PM lcvette_: i have 5000 line incremental encoders
03:07 PM gregcnc_: then you have 20,000 "steps/rev"
03:09 PM gloops: devlap dont forget, this is only moving 3 thou per step, you wont even accelerate to anything like your maxaccel
03:09 PM devlap: I'm not sure how to set it to make it work. Its not working atm.
03:09 PM devlap: SCALE is grads/s?
03:09 PM devlap: err
03:09 PM devlap: MAX_VELOCITY?
03:10 PM devlap: MAX_VEL = 10, MAX_ACCEL = 30, STEPGEN_MAXACCEL = 40, no movement in A
03:10 PM lcvette_: im too new to understand the ini file
03:10 PM lcvette_: manually
03:11 PM gregcnc_: http://linuxcnc.org/docs/2.7/html/config/ini-config.html
03:11 PM gregcnc_: not too hard to learn. ENCODER_SCALE is what needs to be set
03:14 PM gloops: WRAPPED_ROTARY = 1 - When this is set to 1 for an ANGULAR axis the axis will move 0-359.999 degrees. Positive Numbers will move the axis in a positive direction and negative numbers will move the axis in the negative direction.
03:18 PM lcvette_: i have t enter 1500 in encoder pulses per unit to achieve the correct motor rpm at max speed
03:19 PM gregcnc_: encoder pulses must be set correctly for the machine to travel the distance commanded it has nothing to do with maxx speed
03:20 PM gregcnc_: 6mm screw, direct servo?
03:20 PM lcvette_: yes
03:21 PM gregcnc_: step one forget pncconf
03:21 PM gregcnc_: open the ini
03:22 PM gregcnc_: find ENCODER_SCALE for each axis
03:22 PM lcvette_: my problem is i have a good file but its in metric and i need the inch numbers
03:22 PM devlap: stupid rotary axis.
03:22 PM gregcnc_: inches?
03:23 PM lcvette: yeah
03:23 PM lcvette: my buddy has exact same machine but he is in metric and i am in the states and need inches
03:23 PM lcvette: I have his files
03:23 PM lcvette: just changing some input and output locations
03:24 PM cradek: if you're talking about linuxcnc, you can put G21 at the top of the gcode file and run it on your inch machine. it doesn't matter.
03:24 PM cradek: all linuxcnc installs can run inch and mm gcode equally well
03:25 PM gregcnc_: perfect, use his number in metric in the ini. set Axis to display inches
03:25 PM devlap: whats the alarm LED on the TB6600 sinificance?
03:25 PM lcvette: oh i didn't know i could do that
03:26 PM devlap: ( my alarm led is always on on all steppers? )
03:28 PM lcvette: that isn't going to make anything else wonky in the interface?
03:28 PM lcvette: any other settings?
03:28 PM gloops: i think one is basically the ON light, the other comes on when the driver is doing something
03:29 PM Tom_L: devlap, http://www.twovolt.com/2016/07/04/tb6600-based-4-5a-bipolar-stepper-motor-driver/
03:29 PM Tom_L: says At maximum current load TB6600 IC will overheat in some time and a RED LED turns on.
03:29 PM devlap: mine has a red power led, and a green alarm led
03:29 PM devlap: and they are both on.
03:30 PM Tom_L: don't have any 6600 so i dunno
03:30 PM devlap: this is what mine looks like https://www.tmart.com/pgallery/TB6600-Upgraded-Version-32-Segments-4A-40V-57-86-Stepper-Motor-Driver-Controller_p357494.html
03:30 PM gloops: one should only come on when the axis is moving
03:30 PM devlap: this one has two greenies though.
03:30 PM Tom_L: feel special you have an extra led :)
03:31 PM Tom_L: is it acting abnormal?
03:31 PM XXCoder: dont think mine have any led lol
03:31 PM devlap: I can't figure out working settings for my A axis.
03:32 PM gloops: im very weak on electronics, but the tb6600 was definitely more susceptible to noise/ground issues
03:32 PM Tom_L: gloops knows about ground issues
03:32 PM gloops: you dont forget when you learn the hard way
03:33 PM Tom_L: never
03:33 PM gloops: check wiring devlap
03:33 PM devlap: i had it moving like an hour ago
03:33 PM devlap: no wiring change
03:34 PM devlap: just config changes
03:34 PM gloops: well what has changed?
03:34 PM gloops: did you make a copy of the working config before you changed it?
03:34 PM devlap: SCALE, VELOCITY, ACCEL
03:34 PM devlap: I think velocity was 1 or something, it was all real low.
03:35 PM gloops: id try it low again
03:35 PM gloops: make a note of the figures youve calculated
03:36 PM devlap: Well since my X is 800 steps and a 5mm lead screw, it has 160 scale and 40 max vel
03:36 PM devlap: My A axis has 2400 steps/rev in grads, so 2400/400 got me 6 scale
03:37 PM gloops: 3-1 gearing?
03:37 PM devlap: and then 160 scale, 40 max/s is 160*40 steps max, so I figured 6400 steps/s max. 6400/6 got me ~ 1000 so my max velocity I put 1000
03:37 PM devlap: yea 3:1 pulley.
03:39 PM devlap: its making noise, like its getting some command when i try to move it, but no actual movement. I hear it shifting
03:40 PM devlap: sounds like a regular thunk like on a train track
03:40 PM Tom_L: is the stepper wired right?
03:40 PM gregcnc_: STEPGEN_MAXACCEL?
03:41 PM gloops: LIMITs?
03:41 PM devlap: 1 velocity, 2 max accel 3 stepgen_maxaccel
03:41 PM devlap: min max limit is -10000 +100000
03:41 PM Deejay: gn8
03:42 PM gloops: devlap it was doing that clunk before on the other axis when the drivers were dead
03:42 PM devlap: nope.
03:42 PM devlap: Z moved one direction only. A didnt do crap. X/Y where fine.
03:44 PM gloops: scale is steps per degree right?
03:44 PM devlap: grad
03:44 PM devlap: 6 steps / grad
03:50 PM gloops: what was it doing when it was working - like working normally?
03:50 PM devlap: it was turning slow.
03:50 PM devlap: seemed fine.
03:51 PM gregcnc_: what is max_accel?
03:51 PM devlap: 2
03:52 PM gloops: increase
03:52 PM gregcnc_: what is it on linear axis?
03:52 PM devlap: 120 MAX_ACC
03:54 PM gregcnc_: is velocity 1?
03:55 PM devlap: yea
03:56 PM gregcnc_: why aren't you using 1000?
03:56 PM devlap: it worked when going low and not when going high
04:00 PM gloops: a useful thing to do is make a copy of the INI before you change it, you can also go back to a working config then, and compare
04:00 PM gloops: also = always
04:00 PM gregcnc_: are you using axis to move things?
04:01 PM devlap: Manual Control in the linux cnc program
04:01 PM gregcnc_: mdi?
04:02 PM Loetmichel: ah, btw: is there a default key in axis to change the jog distance?
04:02 PM gloops: its very easy to delete a number, or a space or something without realising - then suddenly you go a config that doesnt work and you dont know why
04:03 PM Loetmichel: i.e one keypress: 5mm per jog, next keypress 1mm, then 0,5, 0,1. 0.05, 0.01 and then back to endless?
04:04 PM gregcnc_: http://linuxcnc.org/docs/2.7/html/gui/axis.html#_keyboard_controls
04:05 PM Loetmichel: ah, "I"
04:05 PM Loetmichel: how fitting
04:05 PM Loetmichel: thanks
04:11 PM devlap: just set isolcpus
04:11 PM devlap: getting back into xfce
04:15 PM devlap: So when I raised the jog speed deg/min
04:15 PM devlap: it started working
04:16 PM devlap: I have a feeling my latency jitter is whack :(
04:16 PM devlap: at 240deg/min i get rotation
04:17 PM devlap: when I start it up, its on 23deg/min
04:17 PM devlap: not sure where it gets that exactly. 6 grad/s * 60 ?
04:18 PM gloops: so up the axis max velocity
04:18 PM devlap: where does Manual Control read its jog speed setting from?
04:19 PM gloops: oh that
04:22 PM devlap: well its not anything from the INI
04:28 PM gloops: well, bedtime here
04:32 PM MarcelineVQ: devlap: which manual control, axis or stepconf?
04:37 PM lcvette: ok, so i started poking around in my buddies INI file and his ENCODER SCALE is showing 2000
04:38 PM lcvette: i was of the same mind as you that it would be 4x5000=20,000
04:38 PM lcvette: ENCODER_SCALE = 2000
04:38 PM lcvette: straight from his INI file
04:39 PM lcvette: so now im really confused
04:42 PM lcvette: join
04:43 PM devlap: in linuxcnc not stepconf
04:53 PM lcvette: if anyone has a minute.. I posted a link with my ini file on the linuxcnc board here: https://forum.linuxcnc.org/39-pncconf/34545-problems-understanding-motor-settings
04:58 PM Tom_L: http://linuxcnc.org/docs/2.7/html/config/ini-config.html
04:59 PM Tom_L: look at encoder_scale ther
04:59 PM Tom_L: e
05:00 PM Tom_L: Specifies the number of pulses that corresponds to a move of one machine unit as set in the [TRAJ] section
05:00 PM gregcnc_: oh step/dir drives?
05:05 PM lcvette: yes step direction drives
05:05 PM gregcnc_: the actual encoder on the motor is irrelevant in this case
05:05 PM lcvette: seriously
05:05 PM gregcnc_: you must use the step/rev values the drive is configured for
05:05 PM gregcnc_: yes
05:06 PM lcvette: 3 hour....lol
05:06 PM lcvette: trying to make that crap jive
05:06 PM Tom_L: you could have asked 3 hrs ago :)
05:06 PM lcvette: i did
05:07 PM lcvette: :P
05:07 PM Tom_L: nobody replied?
05:07 PM gregcnc_: inlcude make model of hardware
05:07 PM lcvette: gregcnc
05:07 PM Tom_L: you're the guy that bought the new mill?
05:07 PM lcvette: told me it was important
05:07 PM gregcnc_: servos, 5000 counte encoder
05:07 PM lcvette: yup
05:07 PM lcvette: yup 5000
05:08 PM gregcnc_: so yeah, I assumed linxucnc was closing the loop, but that's not what's going on
05:08 PM lcvette: you helped me the other day over the weekend get my internet up and running
05:08 PM Tom_L: and your bud has his set up for metric
05:08 PM lcvette: yeah
05:08 PM Tom_L: and you're copying his config
05:08 PM lcvette: hes in south africa
05:08 PM gregcnc_: I assumed because of the type of machine it is
05:08 PM gregcnc_: you don't ahve to change anything from his INI if you are using the same gear
05:08 PM Tom_L: i bet he's hot
05:08 PM lcvette: lots of modern servo drives are both pulse and analog
05:09 PM gregcnc_: why not use analog?
05:10 PM lcvette: ooooohhhh...lol.... long story.. but the short is.. they were supposed to be analog drives... and the wrong drives were sent
05:10 PM gregcnc_: not that 1 micron resolution is terrible
05:11 PM lcvette: myself and my buddy both received the wrong model and because of the lag time of the build and shipping, by the time the machines arrived and we noticed.. it was a bit late and the hassle of exchanging and replacing motors and drives was beyond what we wanted to deal with so.. pulse it is
05:12 PM gregcnc_: so his config is for the same drives
05:12 PM Tom_L: sounds like it
05:12 PM lcvette: same drives, same servos, same machine
05:12 PM lcvette: same spindle
05:12 PM lcvette: same everything
05:12 PM Tom_L: same config
05:12 PM Tom_L: same config
05:12 PM Tom_L: same config
05:12 PM gregcnc_: so what doesn't work?
05:12 PM lcvette: only difference is i went with a 7i92_7i77_7i76 and he is using a 5i25_7i77_7i76
05:13 PM lcvette: some differences in config
05:13 PM Tom_L: i think he was trying to set it up for inch and someone told him to use g21 in the gcode instead
05:13 PM lcvette: some different pin locations
05:13 PM gregcnc_: as far as axis configuration
05:13 PM lcvette: we did our schematics seperately
05:13 PM lcvette: axis config is the same
05:14 PM Tom_L: so remap the pins and off you go
05:14 PM lcvette: 7i76 0-3 x.y.z.a
05:14 PM gregcnc_: so the trouble was trying to convert to inferior unit unnecessarily?
05:14 PM lcvette: 7i77 0 is spindle
05:14 PM lcvette: all my tooling is inches
05:14 PM gregcnc_: the machine doesn't know
05:14 PM lcvette: all my cam is setup in inches
05:14 PM lcvette: all my parts are in inches
05:15 PM gregcnc_: it doesn't care
05:15 PM lcvette: all my life has been in inches
05:15 PM gregcnc_: my machines are metric and they work in the US
05:15 PM lcvette: ok
05:15 PM gregcnc_: the config doesn't care about that
05:16 PM lcvette: how about all the small details such as increments for jogging and what not?
05:16 PM gregcnc_: you want to change the GUI to read inches is all
05:16 PM Tom_L: yeah since you both have the same machine and config you should keep it that way so he can assist later
05:16 PM lcvette: tool tables for tooling?
05:16 PM gregcnc_: http://linuxcnc.org/docs/2.7/html/gui/axis.html
05:17 PM devlap: on the parallel bob which pins are for probing
05:17 PM Tom_L: the free ones that say 'input'
05:18 PM lcvette: im fine as long as my interface and all the little details are in inches i deal with on a daily basis
05:18 PM lcvette: it can metric in the backround happily as long as i don't have to calculate stuff or see it
05:18 PM lcvette: lol
05:18 PM lcvette: your saying thats possible?
05:19 PM devlap: looks like second pin down from the side closest to the parallel port corner
05:20 PM lcvette: if so, I think I am done, just need him to look over my changes to the INI and Hal files to make sure I didn't break anything while adjusting for my connections
05:22 PM lcvette: anyone running an ethernet card car to make sure i did the conversion for it correctly?
05:25 PM lcvette: just posted my hal file conversion here: https://forum.linuxcnc.org/24-hal-components/34546-converting-5i25-file-to-7i92-sanity-check
05:26 PM hendrik_cnc: i have not my config files here, but i mean i have the ip set in "loadrt hm2_eth config=" num_encoders=6 num_pwmgens=0 num_stepgens=5 sserial_port_0=00000x""
05:27 PM CaptHindsight: you guys and your maths all the time, it's like it's all related in some way to each other and not magic
05:27 PM gregcnc_: the tool table should also be read in inches if you have the GUI set for inches, that's how it works in other machines I have, but I don't actually have experience with this in Linuxcnc
05:28 PM gregcnc_: it's as if computers are good at math
05:30 PM devlap: so how do I use the probe to set 0
05:34 PM Lcvette_: Join
05:34 PM hendrik_cnc: @devlap net probe parport.0.pin-10-in => motion.probe-input (of course you have to select the right pin)
05:34 PM hendrik_cnc: @Lcvette_ i have not my config files here, but i mean i have the ip set in "loadrt hm2_eth config=" num_encoders=6 num_pwmgens=0 num_stepgens=5 sserial_port_0=00000x""
05:36 PM devlap: I have the pin triggeromg
05:36 PM devlap: I have the pin triggering*
05:36 PM devlap: I'm not sure how to use that in the interface.
05:36 PM devlap: "Probe tripped during a jog"
05:36 PM Lcvette_: Ok, so I need to add the IP address in?
05:36 PM hendrik_cnc: @Lcvette_ i would, look here: http://linuxcnc.org/docs/html/man/man9/hm2_eth.9.html
05:37 PM hendrik_cnc: but i am using 10.10.10.10 as the ip for my board, so maybe you can leave it if you use the default ip.
05:39 PM hendrik_cnc: @devlap so you see the status change in the hal monitor and you don't know how to use the probing in your axis interface?
05:39 PM devlap: Thats correct.
05:39 PM Lcvette_: I am also using 10.10.10.10
05:40 PM hendrik_cnc: @devlap look at <Manual Control> Tab and select Axis Z and click on "Touch Off"
05:40 PM devlap: Does it got in the + or - direction
05:40 PM hendrik_cnc: @Lcvette_ than i assume that you definitily have to set the ip address as i mentioned
05:41 PM emc: lcvette: are you trying to get an ethernet Mesa board working?
05:42 PM hendrik_cnc: @devlap it depends on your axis settings i would say, so it depends. just try it? :-)
05:42 PM Lcvette_: Emc, yes
05:42 PM Lcvette_: 7i92
05:43 PM emc is now known as JT-Shop2
05:43 PM Lcvette_: Preparing to try a new machine with new config for the first time as a first time Linux user
05:43 PM JT-Shop2: one moment
05:43 PM JT-Shop2: lcvette: what OS are you using?
05:43 PM Lcvette_: Stretch
05:44 PM Lcvette_: I've already fished the board
05:44 PM Lcvette_: Flashed
05:44 PM Lcvette_: Successfully
05:44 PM Lcvette_: Have my IP configured on the machine
05:45 PM hendrik_cnc: add the board_ip to the loadrt command
05:45 PM Lcvette_: We were discussing my hal config
05:45 PM JT-Shop2: my step by step for Debian 9 https://mesaus.com/info/debian-9-uspace.txt
05:45 PM JT-Shop2: ah ok you have the ethernet part working?
05:47 PM Lcvette_: Man where was that last week
05:47 PM Lcvette_: Lol
05:47 PM Lcvette_: I think so but I don't think I did it the same way
05:48 PM JT-Shop2: been there for a couple of months lol
05:48 PM JT-Shop2: there is also instructions for getting auto login to work
05:48 PM Lcvette_: You should add in there to have a network connection
05:48 PM JT-Shop2: I send a copy of that with all orders for ethernet cards from my shop
05:48 PM Lcvette_: I couldn't install it until I had a Ethernet cable plugged in
05:50 PM Lcvette_: I don't think I have usoa
05:50 PM hendrik_cnc: ha, autologin is awesome :D
05:50 PM Lcvette_: What's auto login
05:50 PM hendrik_cnc: you don't have to type in your username/password after boot.
05:51 PM Lcvette_: Ah
05:51 PM Lcvette_: Nice
05:51 PM Lcvette_: I don't have uspace
05:51 PM Lcvette_: Or I didn't install it manually
05:51 PM Lcvette_: That I remember
05:52 PM hendrik_cnc: did you install plane debian or a ready to go linuxcnc build?
05:52 PM JT-Shop2: lcvette: you HAVE to have uspace for an ethernet Mesa card
05:53 PM Lcvette_: Linuxcnc Debian stretch
05:53 PM hendrik_cnc: than uspace is installed.
05:53 PM JT-Shop2: type uname -a in a terminal
05:53 PM Lcvette_: Sweet
05:53 PM hendrik_cnc: to confirm, open a terminal and type in uname -a
05:53 PM JT-Shop2: if you installed from the live DVD it's rtai and not uspace
05:53 PM Lcvette_: On my tablet, at the moment
05:54 PM hendrik_cnc: @JT-Shop2 there is also an preempt build
05:54 PM Lcvette_: Yes
05:54 PM Lcvette_: Preempt RT
05:54 PM Lcvette_: Stretch
05:54 PM hendrik_cnc: http://www.linuxcnc.org/testing-stretch-rtpreempt/
05:54 PM Lcvette_: That one
05:54 PM Lcvette_: Yes
05:55 PM Lcvette_: Pcw told me that's the one I want
05:55 PM hendrik_cnc: Did you try to add the board_ip param?
05:58 PM Lcvette_: Not yet
05:58 PM JT-Shop2: oh that's new cool
05:58 PM Lcvette_: Will be a couple hours, dinner, family time, then I'll small out to the shop for a few hours more
05:58 PM Lcvette_: Sneak
05:58 PM hendrik_cnc: i am at my machine in about 10 yours, than i could show u my config :D
05:58 PM hendrik_cnc: hours
05:58 PM Lcvette_: How long will you be there?
05:58 PM hendrik_cnc: about 8 hours than, but i can upload the config to github for example
05:58 PM Lcvette_: Oh sweet
05:58 PM Lcvette_: Ok, it's 7pm here
05:58 PM hendrik_cnc: 1am :-)
05:58 PM Lcvette_: I won't be in the shop until about 9am tomorrow
05:58 PM Lcvette_: Night owl
06:00 PM hendrik_cnc: @Lcvette_ will upload it to https://github.com/HendrikRoth/linuxcnc
06:02 PM devlap: I just don't want it to crash
06:02 PM hendrik_cnc: @devlap you have the stop button in the upper left corner
06:02 PM hendrik_cnc: that saves your machine life ;p
06:02 PM devlap: how fast does it probe
06:03 PM flyback: question
06:03 PM flyback: does linuxcnc allow the use of a sub board with a rtos firmware
06:04 PM flyback: like say you use linuxcnc for everything
06:04 PM Lcvette_: loadrt hm2_eth board_ip="10.10.10.10" config=" num_encoders=6 num_pwmgens=0 num_stepgens=5 sserial_port_0=00000x"
06:04 PM flyback: but the very fine motor movements that need to be realtime you offload to ardunino etc
06:04 PM Lcvette_: Pcw posted it..lol
06:06 PM hendrik_cnc: @devlap ah probing. sorry. i would install "probe_screen" to have the full probe capacibality
06:06 PM devlap: Ok. And how about uh... homing?
06:06 PM devlap: I don't have limit switches or anything
06:07 PM hendrik_cnc: u can manually home
06:07 PM devlap: It says it needs to be homed to touch off.
06:07 PM devlap: Yea I tried G92 Z0 but it says no MDI while note homed.
06:08 PM hendrik_cnc: https://www.youtube.com/watch?v=y1PqoWKYUz4
06:08 PM hendrik_cnc: maybe this helps
06:08 PM devlap: thx
06:09 PM hendrik_cnc: and for probing (probe_screen): https://www.youtube.com/watch?v=wLHdP8T4-Lc
06:09 PM hendrik_cnc: ops, german sorry
06:09 PM hendrik_cnc: https://www.youtube.com/watch?v=1r-12o7pNDY
06:10 PM Roguish: devlap: NO_FORCE_HOMING = 1
06:11 PM Roguish: http://linuxcnc.org/docs/devel/html/config/ini-config.html#_traj_section
06:11 PM devlap: Ok so home axis just sets it, doesn't move it.
06:11 PM hendrik_cnc: yes
06:11 PM Roguish: a very handy parameter
06:12 PM devlap: Thanks, thats a good one.
06:12 PM Roguish: be careful though. homing is how the softlimits are set.
06:32 PM mtpocketscnc1: ayy
09:16 PM saintsinner: All right, guys, let's keep on rolling (the terms used). You know what time it is.
09:16 PM saintsinner: Plastic injection CNC, I need to read on English about the design, what words to use to find some good web-pages about it.
09:16 PM CaptHindsight: saintsinner: tool-less molding?
09:18 PM CaptHindsight: or are you comparing injection molding plastics to CNC machining plastics?
09:18 PM saintsinner: CaptHindsight: A family of plastic injection machines, with arms of elbow-type, high efficiency, energy saving, fast cycle time and high precision. Variable displacement pump is applied to this series, which incorporate single-cylinder plastic injection and differential clamping motion devices.
09:19 PM saintsinner: If it is acceptable, I can ask here.
09:19 PM CaptHindsight: sounds like patent doubletalk
09:19 PM CaptHindsight: go ahead
09:19 PM CaptHindsight: it's a quiet time of the day here
09:20 PM saintsinner: CaptHindsight: this is translation from Chinese.
09:20 PM saintsinner: So, elbow-type -this means two arms with a joint between them, right?
09:20 PM CaptHindsight: possibly
09:20 PM CaptHindsight: differential clamping motion devices
09:21 PM CaptHindsight: clamps that move
09:21 PM saintsinner: these are one or more clamps at once, right&
09:21 PM CaptHindsight: possibly
09:22 PM CaptHindsight: have a link to the Chinese source?
09:23 PM CaptHindsight: injection molding machines have dies, arms, pumps etc
09:23 PM CaptHindsight: doesn't sound like anything new
09:23 PM saintsinner: - Linear position transducer monitoring plastic injection action
09:23 PM saintsinner: I know that this is a linear-scale monitor for the electronic thingie used to control the process. But I need to read somwhere on it, I need standard definitions.
09:23 PM CaptHindsight: linear encoder
09:23 PM saintsinner: Exactly, this is not something new.
09:24 PM CaptHindsight: linear-scale monitor^^
09:24 PM CaptHindsight: electronic thingie used to control the process = controller
09:24 PM CaptHindsight: clamps might means dies
09:25 PM saintsinner: dies?
09:25 PM CaptHindsight: https://5.imimg.com/data5/JF/NI/MY-3561410/plastic-injection-molding-die-500x500.jpg
09:26 PM CaptHindsight: shown with the two halves apart
09:27 PM saintsinner: Well, as a standard set, it probably contains clamps as some sort of addition to "Anti-slip aluminum checkered plate"
09:27 PM CaptHindsight: https://youtu.be/b1U9W4iNDiQ?t=28s
09:27 PM CaptHindsight: how dies work with the pump ^^
09:29 PM CaptHindsight: https://www.youtube.com/watch?v=d4F9jvMBk0Y
09:31 PM saintsinner: "single-cylinder plastic injection device" - I thought it is somewhat on the end of an arm, i.e. the working organ itself
09:36 PM saintsinner: And it has a dual-cylinder version, and even "Embedded injection cylinder mechanism"--and a variety of "control levels" used
09:37 PM saintsinner: Display of rotating speed of molten plastic--this is understood quite easily as RPM during the mixing of molten plastic.
09:38 PM saintsinner: This is what I can not understand:
09:40 PM saintsinner: "Tie rod protection system against cold startup"--is this a protection system for the positioning arms, from the beginning of their moves, when the plastic isn't melted. This imagination sounds incorrect.
09:47 PM saintsinner: So, the type of such machines is actually just one, as on these videos, and there is nothing new, right.
09:59 PM lcvette: hey guys.. anyone running AC Servos in Pulse mode?
09:59 PM lcvette: with mesa 7i76
10:02 PM lcvette: curious what your [# Axis_0,X,Y, etc] INI setting look ike
10:02 PM lcvette: for comparison
10:06 PM saintsinner: lcvette: this is a night time, they will be here after about 10 hours or so. For example, here 10:00 AM, I am at GMT+7. And I would try to ask someone here at "my" 5:00 AM
10:08 PM Tom_L: saintsinner, where are you?
10:08 PM Tom_L: au?
10:08 PM saintsinner: Tom_L: Russia, Siberia
10:08 PM Tom_L: ok
10:09 PM CaptHindsight: lcvette: pulse mode?
10:09 PM CaptHindsight: PWM on a hobby servo?
10:09 PM Tom_L: pwm i'm guessing
10:09 PM Tom_L: no
10:09 PM Tom_L: he's got a commercial cnc
10:09 PM Tom_L: new in fact
10:09 PM Tom_L: ordered from china with no control
10:09 PM CaptHindsight: pulse = step?
10:09 PM Tom_L: probably
10:10 PM CaptHindsight: step and dir servo?
10:10 PM Tom_L: i think so
10:10 PM Tom_L: i think he said it would do step/dir or analog
10:10 PM CaptHindsight: says 7i76 so Step and Dir
10:10 PM Tom_L: yeah
10:11 PM CaptHindsight: so it's just like a stepper setup
10:12 PM CaptHindsight: only with encoders
10:12 PM Tom_L: sounds that way
10:12 PM CaptHindsight: anyway, he can let us know when he's here again
10:12 PM CaptHindsight: or tell hi I said that :)
10:12 PM CaptHindsight: hi/him
10:12 PM Lcvette_: Pulse yes
10:12 PM CaptHindsight: ah still here!
10:12 PM Tom_L: tell him yourself
10:13 PM Lcvette_: Pcw caught some questionable settings in my buddies in file
10:14 PM Lcvette_: There p values were a bit high he said
10:14 PM CaptHindsight: Tom_L: oh sure, now you stop talking for him
10:14 PM Lcvette_: ~ 2700-3000
10:14 PM Lcvette_: Hey Tom!
10:15 PM Tom_L: CaptHindsight, https://uploads.tapatalk-cdn.com/20160605/b064df24d7eb6206d90877686aea442d.jpg
10:15 PM CaptHindsight: Lcvette_: post your configs on pastebin
10:15 PM Tom_L: https://www.cnczone.com/forums/uncategorised-metalworking-machines/309614-cnc-tormach-posts.html
10:15 PM Lcvette_: Tom is one of my heros,. He's been patient in helping me sort through all kinds of mess
10:16 PM Lcvette_: What's pastebin?
10:16 PM Tom_L: a place to paste code
10:16 PM CaptHindsight: https://pastebin.ca/
10:16 PM CaptHindsight: try this link ^^
10:17 PM saintsinner: Lcvette ten years have already gone, and some of them are here.
10:17 PM CaptHindsight: then everyone here can see your config files
10:17 PM Tom_L: or paste.debian.net etc
10:17 PM CaptHindsight: yeah plenty to choose from
10:17 PM Lcvette_: https://forum.linuxcnc.org/39-pncconf/34545-problems-understanding-motor-settings
10:17 PM Lcvette_: Ok
10:17 PM CaptHindsight: anyway, I'm heading out
10:17 PM Tom_L: me 3
10:17 PM Lcvette_: I pasted the in file there too but I'll go to paste bin now
10:18 PM CaptHindsight: Lcvette_: post the files and the questions
10:18 PM Tom_L: you may have to post it again in 8hrs when we're awake
10:18 PM CaptHindsight: Lcvette_: oh that works as well
10:18 PM CaptHindsight: just so it's somewhere people can see
10:19 PM CaptHindsight: or 12 if you are like me
10:19 PM CaptHindsight: those EU guys are here in 2-3 hours
10:19 PM CaptHindsight: they get up really early
10:19 PM Tom_L: yeah that's just crazy
10:20 PM Tom_L: why would _anybody_ get up so early :)
10:20 PM lcvette: https://pastebin.ca/4024212
10:20 PM lcvette: like that?
10:20 PM Tom_L: yeah
10:20 PM CaptHindsight: something about catching birds with worms
10:21 PM Tom_L: i saw a hawk today in the sky with a large snake
10:21 PM CaptHindsight: lcvette: the forum is a great place to post questions
10:21 PM Tom_L: CaptHindsight, he and his bud have identical machines
10:22 PM Tom_L: but different mesa cards
10:22 PM Tom_L: as i understand i t
10:22 PM lcvette: http://pastebin.ca/4024214
10:22 PM Tom_L: so he's moving pins around
10:22 PM lcvette: and thats my hal file
10:24 PM lcvette: correct
10:24 PM lcvette: i moved some pics around
10:24 PM lcvette: but only I/O's
10:24 PM lcvette: not any of the motor stuff
10:25 PM lcvette: my buddy won't be at his shop for a few hours hes still asleep
10:26 PM lcvette: so I have to stay awake until 2am my time to talk to him and go over my progress today and get his input and help with his files on a few things i didn't understand or see
10:26 PM lcvette: I feel like im soo close i can taste it
10:27 PM lcvette: hoping t have some movement tomorrow
10:27 PM CaptHindsight: lcvette: what problem are you currently having?
10:28 PM lcvette: learning and understanding
10:28 PM lcvette: lol
10:28 PM lcvette: I am just getting things prepared to put to the machine
10:28 PM CaptHindsight: it takes a little bit of work
10:28 PM lcvette: yes indeed
10:28 PM lcvette: steep learning curve
10:29 PM lcvette: much reading
10:29 PM CaptHindsight: I have to do a few things and leave, so I wish you much success
10:29 PM lcvette: much help in here to understand what i read
10:29 PM lcvette: thank you very much!
