12:50 AM sensille: hehe. when googling for "manual toolchange 3d probe workflow", the first hit that comes up is "I feel your pain with linuxcnc, everything is hard but have patience it will become easier by the time you are finished (but its still hard)."
01:00 AM jpa-: sensille: my workflow is: automatic tool setter pad, after changing 3d probe just set the tool length normally (with a macro), measure & zero coordinates, switch tool and autoset length
01:00 AM jpa-: for me it works because the probe & toolsetter are at same pin, and the toolsetter is just a rigid contact pad so the 3d probe detects it
01:12 AM sensille: the tool change dialog on qtdragon is totally weird
01:13 AM sensille: why does it prompt me for a spindle speed?
01:17 AM sensille: I guess the best way is to change the tool before i run the program
01:17 AM sensille: and don't have programs with tool changes in it

01:31 AM sensille: this is informative (if it still holds) http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WhyManualWhilePausedIsHard
03:59 AM travis_farmer[m]: G'Morning
04:00 AM Deejay: hi
04:00 AM travis_farmer[m]: howdy :-)
04:04 AM travis_farmer[m]: so, last night, as i lay in bed, i had a panic moment, wondering how i was going to use my 3D probe with my ATC spindle. not like i can have it wired in, and sit in a changer waiting to be used... then this morning, it hit me, DON'T have it in the changer. just mount it in a tool-holder, and mount a fork on the Z-axis, where it is wired in, and just let it ride around until i need it, and when i do, just change it in manually. it
04:04 AM travis_farmer[m]: seems so simple now, but was full panic mode last night... lol :-)
04:25 AM rmu: travis_farmer[m]: nothing says the probe has to be in the spindle to probe. also there are affordable wireless probes
04:26 AM travis_farmer[m]: Hmm, interesting point. i could just mount it offset, as long as i know the exact offset relation from the probe to the spindle center
04:27 AM travis_farmer[m]: i will also look into the wireless probes
04:31 AM rmu: you can probe the offset
04:32 AM travis_farmer[m]: yes, i am aware. just bore a hole, get the location of the hole, then move the probe over and center probe the hole, thus giving me the offset :-)
04:34 AM rmu: main problem is mounting the probe such that it is out of the way when not needed and on a repeatable position when probing
04:35 AM travis_farmer[m]: i thought of that. also, if it will be in the way of a dust collection shoe
04:37 AM travis_farmer[m]: really it depends on what i will use the probe for. i don't plan on deep-probing. mainly just surface height, and rotational angle in case the piece of wood is rotated a little bit
04:40 AM travis_farmer[m]: so if the probe extends just 3/4 inch or so below the unloaded spindle nose, "in theory" it should be alright. though maybe a safer bet would be to just have it just above the nose of the tool-holder collet, in my shortest tool-holder. that should keep it out of the way, as long as i don't probe with a loaded spindle ;-)
04:41 AM travis_farmer[m]: that would give me about 1.25 inches of probe exposure
04:42 AM travis_farmer[m]: i will though, have to make the dust collection shoe retractable, not just for probing, but for tool changes as well
04:44 AM travis_farmer[m]: or have the dust shoe fixed, and just flip up the surrounding brush hair...
04:50 AM sensille: sounds like the wireless probe is the easier option
04:50 AM travis_farmer[m]: except i already have a probe, and it is wired in.
04:58 AM sensille: convert it to wireless, nice small electronics project :)
04:59 AM rmu: convert wired probe to wireless in 3 easy steps 1) draw schematics 2) buy hardware 3) assemble
05:00 AM -!- #linuxcnc mode set to +v by ChanServ
05:09 AM JT-Cave: morning
05:11 AM travis_farmer[m]: idea wise, i am leaning toward a dust shoe that mounts high up on the spindle nose, and retracts the brush hair up inside, and out of the way for tool changes and 3d probing. it does perhaps sound complicated, but in my mind it seems so easy... perhaps i will draw it up in CAD, see if it is as complicated as it sounds. ;-)
05:25 AM rmu: travis_farmer[m]: https://www.youtube.com/watch?v=gRrhYydcw6s 1992 era professional wood monster converted to linuxcnc doing a toolchange in slomo. dust shoe removed, but it fits over the "fork". with this particular machine the spindles sit on a pneumatic "sub-z-axis". with a typical ganty-type machine you wouldn't need that and you wouldnt need the rising tool pockets.
06:09 AM sensille: would it be ok to cut downwards with t-slot cutter like this? https://www.aliexpress.com/item/4000346879675.html
06:09 AM sensille: or just sidewards?
06:15 AM travis_farmer[m]: looks like it has bottom cutters, but i would go slow. what material are you cutting into?
06:15 AM sensille: wood
06:16 AM travis_farmer[m]: yeah, should be alright
06:51 AM travis_farmer[m]: well, this is how my morning is going so far... bumped my side table, knocked over my coffee, spilled coffee all over myself and the couch... some days, it would just be easier if i didn't wake up...
06:53 AM * sensille goes back to feeeling stupid. the probe basic screen in qtdragon is infuriatingly hard to use. i guess i'll end up wiring my own
06:54 AM * travis_farmer[m] posted a file: (98KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/CSelaXUmONfcoMWIEWlvMRkw/dust%20shoe.pdf >
06:54 AM travis_farmer[m]: but i managed to sketch up a stupid looking dust shoe with retractable brush hair... no notes or dimensions on the drawing, because i couldn't figure out how at the moment...
06:56 AM Tom_L: morning
06:58 AM travis_farmer[m]: and Fusion360 just crashed... so, how is everyone elses days going so far? :-)
07:07 AM * travis_farmer[m] posted a file: (103KiB) < https://libera.ems.host/_matrix/media/v3/download/matrix.org/wtlYWfqFNKzOdKPGcFkGgHsy/dust%20shoe2.pdf >
07:07 AM travis_farmer[m]: added notes
07:10 AM travis_farmer[m]: odd, closed Fusion360, and my computer rebooted... never had that before...
07:13 AM travis_farmer[m]: oh... Winblows 10 has decided to update... likely the root of my current computer issues...
07:19 AM * Tom_L wonders if JT-Cave found his C8 yet
07:20 AM * travis_farmer[m] wishes he could afford a C8... would not buy one, just wishes he could afford one... ;-)
07:31 AM JT-Cave: almost but not quite https://www.chevrolet.com/locate-inventory/corvette/details#?radius=500&conditions=New&includeNearMatches=true&postalCode=63901&locale=en_US&makes=Chevrolet&models=Corvette%20Stingray&trims=3LT&rearWheels=Single&bodyStyles=Coupe&drivetrainCode=RWD&years=2023&tiresCodes=XFN&interiorOptionCodes=CAV&interiorOptionCodes=RIA&packageCodes=PEF&interiorColorCodes=HTE&wheelsCodes=Q9I&exteriorColorCodes=GS7&engineCodes=LT2&mechanicalCodes=E60&mechan

07:39 AM JT-Cave: it has yellow seat belts, it's in Chicago, and he is elusive on the price
07:41 AM JT-Cave: chickens are up time to clean chicken shit
08:07 AM JT-Shop: when you get to your golden years life is a bit different
08:08 AM travis_farmer[m]: be lucky if i even live that long...
08:12 AM JT-Shop: chance for a bit of snow today
08:52 AM travis_farmer[m]: 13F in my shop right now... this plastic chair is COLD!
08:55 AM JT-Cave: chickens have been taken care of time for break fast
08:58 AM travis_farmer[m]: hmmm, spindle makes funny noises when it is 13F... maybe i will run it at 24000, unloaded for a bit to warm up the bearings...
09:00 AM travis_farmer[m]: hey, my comp works! it is not exactly the set speed, but enough for the at-speed indicator and reporting to work as it is supposed to :-)
09:02 AM * travis_farmer[m] wonders why most standard sized T-nuts and T-bolts that i have seem to have a 7/16 T-track width... my machine has 3/8 inch wide tracks
09:05 AM travis_farmer[m]: have to grind the width down on all of them i guess... or at least enough to hold down my spoilboard...
09:11 AM travis_farmer[m]: geeze, so cold out here, i can't touch metal... :-)
09:15 AM _unreal_: So wildly pissed off. I just tried powering my OPI5 for the first time. ITS TOTALLY DOA out of the box. WTF...
09:15 AM sensille: bad power supply?
09:16 AM _unreal_: nope
09:16 AM _unreal_: the power supply is fine
09:17 AM _unreal_: I plug it in. the RED power light turns on and thats it
09:17 AM travis_farmer[m]: yeah, that would piss me off too...
09:17 AM _unreal_: HDMI, USB-C TO HDMI does not mattter
09:17 AM _unreal_: the green light that shows activity does not do anything
09:17 AM _unreal_: I can hold the power button for 4 seconds and the RED light will turn off. press it and it will turn on but thats it.
09:17 AM _unreal_: no life period
09:17 AM _unreal_: its dead
09:18 AM sensille: the rpi i have is quite picky when it comes to power
09:18 AM _unreal_: I'm using the PSU that was shipped with it. I have already tried an other one as well
09:18 AM _unreal_: nothing
09:19 AM travis_farmer[m]: stupid question, has it got an OS loaded?
09:20 AM _unreal_: does not need one
09:20 AM _unreal_: It has an onboard built in bootloader
09:21 AM _unreal_: It has an ??? 8 or 16 MB onboard flash.
09:22 AM travis_farmer[m]: guess i don't know much about the Orange PI... i just knew my Rpi needed an OS to do anything... may be wrong, likely am
09:23 AM _unreal_: 16mb spi flash onboard
09:24 AM skunkworks[m]: roycroft: The best part of the upgrades was I did it all from home while tinkering... (thinking I would have to go to work at some point to fix a non-booting problem)
09:27 AM travis_farmer[m]: well, too damn cold out in this shop to get anything done. the diesel heater just isn't making any difference...
09:50 AM Rab: _unreal_, https://forum.armbian.com/topic/22354-first-boot-with-only-red-led/
09:51 AM Rab: Not sure if this is helpful, but there are a couple of things to try.
09:52 AM _unreal_: rab I have the ornage pi 5
09:52 AM _unreal_: I'm writing the android image to a different sd card right now
09:53 AM _unreal_: I wrote the unbuntu image to a 128gb sd card. It should work. right now I'm prepping to test using a 64gb card.
09:54 AM _unreal_: got to love all the shit I get from the boat yard. hehe I got a 128gb sd card last week. It was in a gopro originally. video os people having a hell of a time on a big as CAT sailboat.
09:54 AM _unreal_: nothing too exciting and now ereased >:)
09:54 AM _unreal_: blaaa 58% written still waiting.
10:11 AM _unreal_: ok just tested 2 different SD cards. pure and simple its not doing anything
10:28 AM travis_farmer[m]: is there a way to set soft limits in LCNC for my tool change area, and only enter them when ready to change?
10:29 AM travis_farmer[m]: actualy, i just thought of how, with a limit switch, and a hal comp..., NVM :-)
10:39 AM Tom_L: JT-Cave, that's funny because i picked that color and one reddish one
10:40 AM Tom_L: hah, wishes are for talkers
10:40 AM JT-Shop: yup
10:41 AM Tom_L: https://www.caranddriver.com/news/a33247423/2021-chevy-corvette-c8-details-revealed/
10:41 AM Tom_L: was the other color choice but i'd never buy a red car
10:41 AM _unreal_: ok so I just ordered an FTDI adapter. I'm sure I have one but have no idea where it is IF I have one.
10:41 AM Tom_L: _unreal_, you in miami?
10:42 AM _unreal_: then I can at least look at the @#$%@#$%$ thing and see if its totally DOA or not
10:42 AM _unreal_: I'm an hour north or so.
10:42 AM _unreal_: why?
10:43 AM Tom_L: just curious, i'll be passing thru in a few weeks
10:45 AM _unreal_: ahh... vacation?
10:48 AM _unreal_: Tom_L, ?
10:48 AM Tom_L: phone
10:51 AM JT-Shop: https://www.chevrolet.com/performance/corvette/build-and-price/exterior
11:21 AM _unreal_: !!!!!! ?? OK wtf. THE OPI5 just booted?
11:22 AM travis_farmer[m]: i am happy for you! now you just have to figure out what was different, no matter how small... ;-)
11:30 AM travis_farmer[m]: ...i love when i am writing code, and get halfway done, when i realize i did it all wrong... i mean, that is like walking out to your car in a public parking lot after a big snow storm, and you clean most of the snow off your car (or truck), and then realize you have in fact just cleared off somebody else's vehicle... :-)
11:37 AM unterhausen: It looks like we are probably just going to get rain. That would be nice, since I have to drive Hershey tomorrow
11:48 AM jpa-: travis_farmer[m]: well, then at least someone benefits - but wrong code is just useless :)
11:49 AM roycroft: the rain will return here on tuesday
11:50 AM travis_farmer[m]: yeah, i am now going through to see if anything is savable, but not much so far... worst case, if i delete too much, there is always version history on GitHub :-)
11:55 AM travis_farmer[m]: i was writing the code backwards. starting with the journey, and without a defined destination. now i am trying to define what the code needs to do, and i will fill in how i need to get there, as i go.
12:07 PM _unreal_: I have no idea what changed
12:07 PM _unreal_: because I didnt do anything differetn.
12:07 PM _unreal_: I just plugged it back in and the green access light started blinking after 5 seconds. NEVER did before.
12:14 PM _unreal_: ? ok I think I just got HDMI working?
12:14 PM _unreal_: very odd
12:51 PM Bleepshop: _unreal_: Fighting with your OPi5?
12:54 PM Bleepshop: JT-Shop: Been thinking and I don't need indicating fuse-holders. I want to run "Power Good" LEDs on the front panel for each suppy rail. So I just need to find some standard disconnect holders.
12:54 PM _unreal_: Its working now but I dont know if I have an HDMI issue or its some ODD ball setting issue? I really dont know its booted regardless
12:54 PM travis_farmer[m]: ideas are always so simple in my head... if, and it is now a big IF, i make a matrix magazine tool changer, powered by a Arduino, that moves the changer via another Arduino running GRBL... i was playing around and it occurred to me, i would not just send Gcode commands and hope for the best, but i would have to parse the response for errors, alarms, and general gibber jabber... all possible, but makes one rethink when a hobby goes
12:54 PM travis_farmer[m]: from fun, to PITA ;-)
12:54 PM _unreal_: Bleepshop, I looked and only found one of those din rail fuse holders
12:54 PM Bleepshop: _unreal_: Or you have a bad connection.
12:55 PM _unreal_: very well could be
12:55 PM _unreal_: I really dont know and only have one monitor I've tested with.
12:55 PM _unreal_: I'm just happy its powered up....
12:55 PM Bleepshop: _unreal_: Yeah, JT said he might have some as well.
12:55 PM _unreal_: before It would not even boot from the SD card that is what was FUCKING with me
12:55 PM _unreal_: zero life
12:56 PM _unreal_: then it just started working like 2 hours later plugged it back in and it just started to boot. WTF...
12:56 PM _unreal_: I cant explain that
12:56 PM _unreal_: It totally fucked me though. I was planning on doing 3d printing or cnc milling parts of the case I had designed today. I spent all day trying to get the damn thing to post.
12:56 PM Bleepshop: _unreal_: OH!. That's the standard "image failed to properly write" issue that plagues me with RPi 3s & 4s. LOL
12:57 PM _unreal_: I didnt do anything
12:57 PM _unreal_: I just didnt touch it for 2 hours came back
12:57 PM _unreal_: pluged the power in and it just booted
12:57 PM _unreal_: i DIDNT DO ANYTHING it just decided finally to work.
12:57 PM Bleepshop: First boot is always a "go get coffee or laid" and come back after the partition is resized. LOL
12:58 PM _unreal_: no it would not post it would not do anything
12:58 PM _unreal_: It was totally dead
12:59 PM Bleepshop: Congratulations. You've performed an act of Technomancy and revived a dead machine. LOL
01:00 PM _unreal_: I want to download this ornage pi OS image. but it keeps failing https://drive.google.com/drive/folders/1cTxzxRh7gCLBh3qe0JDn100_bjKrpIbx
01:00 PM _unreal_: err wait no wrong link
01:00 PM _unreal_: that wont even work
01:01 PM _unreal_: this should be the right link
01:01 PM _unreal_: https://drive.google.com/drive/folders/1YxOLUAunufM6NzAfeEmt5tUnAFOu5bdA
01:01 PM Bleepshop: I'm getting a "Download Quota Exceeded for this file"
01:01 PM _unreal_: the NVME image is what I'm trying to download
01:01 PM _unreal_: ?
01:02 PM _unreal_: wtf does that mean?
01:03 PM Bleepshop: It means that's a popular file and it needs to be copied to github or something where Go-Ogle won't be limiting the downloads to upsell services. :/
01:03 PM Tom_L: it means he didn't pay his internet bill :)
01:04 PM JT-Woodshop: lol
01:04 PM Bleepshop: Dunno about his internet bill but he damn sure didn't Grease google. LOL
01:08 PM Tom_L: i never visit a locksmith: http://tom-itx.no-ip.biz:81/~webpage/cnc/Locksmith.jpg
01:11 PM DigitalReaper: that's a nice high-res picture of your key there... on a completely unrelated note where do you live?
01:12 PM travis_farmer[m]: lol
01:16 PM Tom_L: not stupid. that was the old one
01:16 PM travis_farmer[m]: he says that now... ;-)
01:18 PM _unreal_: ? wow maybe the download is going to work this time? i'm 2min away from getting that file to download finally
01:20 PM * JT-Woodshop wonders why Sorby doesn't have anything between 1 3/8 and 2 3/4 jaws...
01:30 PM Bleepshop: JT-Woodshop: Did you say you've got DIN fuseholders?
01:31 PM JT-Woodshop: yes
01:32 PM JT-Woodshop: dc or ac indicating fuse holders
01:33 PM JT-Woodshop: how many do you want?
01:42 PM Bleepshop: JT-Woodshop: I'm looking for straight fuseholders. Non-indicating. I've got 5VDC,12VDC,40VDC and 110/220VAC want to run power good LEDs on the panel.
01:43 PM travis_farmer[m]: what? no 24VDC? here i thought 24VDC was standard machine voltage ;-)
01:46 PM Bleepshop: Depends on the machine. I've got stuff at work that the control circuits run 5VDC [portable sawmill], 24VDC [40" triple head sander] or 110VAC [6 head molder].
01:47 PM Bleepshop: Then there's the block slicer that is happy with 6VDC-48VDC. LOL
01:47 PM JT-Woodshop: let me see what else I have
01:49 PM JT-Woodshop: I have some 6awg 8a 600v fuse holders
01:49 PM Bleepshop: JT-Woodshop: If you don't have any I'll just grab a pack of these. https://www.amazon.com/uxcell-10Pcs-ASK1EN-Holder-Terminal/dp/B06ZZMD9Z2/
01:51 PM _unreal_: Bleepshop, if there are any other things your looking for for din rail let me know. I now that I think of it may have other ziplock bags I've forgotten about that may have a lot more din stuff....
01:52 PM vetsin: kinda dumb question, but how would one go about debugging why i can't jog my steppers via pnconf?
01:53 PM Bleepshop: vetsin: Is the Mesa board powered?
01:54 PM vetsin: good first step, but yes. powered responds to ping
01:54 PM Bleepshop: Got the right board selected?
01:54 PM vetsin: can confirm
01:55 PM travis_farmer[m]: does the board have firmware loaded?
01:55 PM vetsin: that i have not seen how to confirm
01:55 PM pcw-home: I would test motion with a linuxCNC configuration rather than in pncconf
01:55 PM Bleepshop: Made sure that your ste/dir/enable wiring is correct?
01:55 PM vetsin: pcw-home: i validated it's what i expect, though i'm not sure how to *actually* validate
01:56 PM vetsin: er, meant to say tha to Bleep
01:56 PM Bleepshop: Vetsin. Super simple logic probe. 2 LEDs and 2 1K resistors.
01:57 PM pcw-home: Most common step/dir issues are 1. wiring, 2. Too short step pulses, 3. Global issues (like real time problems)
01:57 PM vetsin: ahh, okay. So to validate wiring can i must meter the boards enable for voltage?
01:58 PM travis_farmer[m]: usualy the enable is drawn low on most stepper drivers, to enable
01:58 PM pcw-home: Normally you would not connect to the step/dir drives enable inputs
01:59 PM pcw-home: (because they are disable inputs)
01:59 PM vetsin: oh, so i can just unwire those to reduce variables here
01:59 PM pcw-home: yes
01:59 PM vetsin: ty
02:03 PM vetsin: oh my god disconnecting those fixed it
02:03 PM vetsin: thanks a ton
02:04 PM travis_farmer[m]: yeah, the enable pin was likely set to enable HIGH, rather than LOW
02:04 PM vetsin: where would that normally be set? the hal?
02:05 PM Tom_L: you can invert the pin
02:06 PM vetsin: awesome.
02:07 PM vetsin: beyond that, i was looking at my manual docs and i'm a little confused on figuring out the 'stepper info' and setting my pulse/rev
02:07 PM vetsin: do yall know of any good reading resources on the topic?
02:11 PM Tom_L: https://linuxcnc.org/docs/2.6/html/common/Stepper_Diagnostics.html
02:11 PM Tom_L: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Drive_Timing
02:12 PM Tom_L: on pin invert: setp hm2_[HOSTMOT2](BOARD).0.gpio.001.invert_output 0 or 1
02:13 PM Tom_L: # GPIO pin parameters are:
02:13 PM Tom_L: # .in, .in_not, .out, .invert_output, .is_opendrain, .is_output
02:13 PM Tom_L: syntax may vary slightly
02:14 PM vetsin: roger
02:19 PM JT-Woodshop: vetsin, what board?
02:19 PM vetsin: 7i76e with cl86t drivers
02:20 PM travis_farmer[m]: great, the 6mm air line fittings i need for my ATC spindle, that i ordered several days ago? the seller just went on vacation, and couldn't be bothered to ship before then... i sent them a message to cancel the order, as they are not off vacation until sometime in February! very bad customer service, IMO!
02:20 PM JT-Woodshop: loadrt hostmot2
02:20 PM JT-Woodshop: loadrt hm2_eth board_ip=10.10.10.10
02:20 PM JT-Woodshop: then in another terminal
02:21 PM JT-Woodshop: halcmd show all hm2 > 7i76e-pins.txt
02:21 PM JT-Woodshop: that will give you a list of all pins and parameters
02:22 PM JT-Woodshop: 6mm x what?
02:22 PM vetsin: is loadrt supposed to be on my path?
02:22 PM travis_farmer[m]: 6mm X 1/4"npt
02:22 PM JT-Woodshop: if you have linuxcnc installed yes
02:23 PM travis_farmer[m]: 1/4"npt (male)
02:25 PM JT-Woodshop: hmm I have a few 6mm tubing fittings but with like 1/8" thread or smaller
02:26 PM JT-Woodshop: got a bunch of 8mm tubing fittings...
02:26 PM JT-Woodshop: 6mm tube fittings on the spindle?
02:26 PM travis_farmer[m]: yes
02:27 PM JT-Woodshop: I gave a lot of my metric tubing stuff to my buddy at Revere
02:28 PM Bleepshop: travis_farmer[m4: Check the local plumbing supply. 6mm PTC fittings are getting easy to find.
02:28 PM travis_farmer[m]: i can probably find another seller, i was just a little PO'ed that the guy went on vacation before shipping
02:29 PM Bleepshop: Same every year. Last 2 weeks of Jan is always sketchy when ordering from China.
02:29 PM travis_farmer[m]: this was from florida...
02:30 PM Bleepshop: I need 3 closed loop Nema-42s at work. Can't do shit till Feb 1 when they open again.
02:30 PM vetsin: do people normal do limit switches normally open or closed?
02:30 PM Bleepshop: vetsin: I do them closed. wiring failure will stop you as well.
02:31 PM travis_farmer[m]: yeah, what Bleepshop said
02:31 PM vetsin: that was my thought, ty
02:38 PM JT-Woodshop: yep N/C for limits and make sure you can't crash into the switch
02:38 PM Tom_L: yes... we preach from experience
02:39 PM JT-Woodshop: https://gnipsel.com/images/bp-knee-mill/BP%20Limits.jpg
02:39 PM XXCoder: thats good design. no limit switch smashy
02:39 PM * JT-Woodshop goes to spoil the hens
02:40 PM * Tom_L goes for a nap
02:40 PM travis_farmer[m]: i was amazed to see my machine destroy a home/limit switch, when i forgot to connect it correctly in HAL ;-) learned real quick then...
02:43 PM travis_farmer[m]: heh, i also crashed into a power supply that was laying on my table, that i didn't see behind the gantry supports... crushed it real good when the Z came down. didn't know it had that much downforce... ;-)
02:44 PM travis_farmer[m]: was a good 12V PSU too... would be handy if it still worked... ;-)
02:46 PM travis_farmer[m]: being complacent around a machine is never a good thing
02:54 PM vetsin: another question, if my MPG has a 'COM' or 'switch input common point' is that normally wired to 0vdc?
02:55 PM JT-Woodshop: 24vdc into common and 24vdc out from the switch
02:56 PM vetsin: confusing since the MPG has a VCC/0V already
02:57 PM JT-Woodshop: the mpg part should be 5vdc
02:58 PM JT-Woodshop: which mpg?
02:58 PM vetsin: oh so the jog is supposed to be 5vdc but the com itself is supposed to be 24vc?
02:59 PM vetsin: https://www.ebay.com/itm/274274834922 one of these guys
03:00 PM pcw-home: Normally MPGs are powered by 5V. If you use the 7I76E MPG inputs the 5V MPG supply common (negative) must connect to the 7I76E field power common (negative)
03:04 PM Bleepshop: vetsin: I think I got the same MPG with an STM32 controller board.
03:04 PM JT-Woodshop: com looks like an enable button for the two rotary switches
03:05 PM vetsin: is that what that button on the left of this thing is supposed to be...
03:05 PM JT-Woodshop: looks like it from the "connection table"
03:05 PM vetsin: makes more sense, ty
03:05 PM JT-Woodshop: yw
03:05 PM * travis_farmer[m] has very tired eyes from looking at a screen all day... taking a nap
03:07 PM Bleepshop: vetsin: You got 18 wires in your MPG cable?
03:07 PM pcw-home: I have tired eye from debugging 100 lines of assembly and taking 5 hours to find two really stupid bugs
03:08 PM vetsin: yeah lol
03:08 PM Bleepshop: pcw-home: They can't have been that stupid, They hid from you for a while. ;D
03:09 PM Bleepshop: vetsin: OK. COM is a common connection for all the switches if I'm reading this right.
03:09 PM pcw-home: I guess I should think myself clever for creating bugs I could not see...
03:09 PM vetsin: which... would be 5vdc then...?
03:10 PM JT-Woodshop: that's pretty clever
03:10 PM Bleepshop: x100, x10, x1, 4, 5, 6, z, x, y
03:10 PM Bleepshop: vetsin: Doesn't care. they're mechanical switches.
03:11 PM Bleepshop: vetsin: You could run 20ma @110V through the ones on mine.
03:11 PM vetsin: i see your point
03:12 PM vetsin: in *my* case since my 7i76e i have all of those things wired to inputs, the COM should be my vcc
03:12 PM pcw-home: For a 7I76E you would connect the switch common to +field power (probably +24V)
03:12 PM Bleepshop: You do need the 5V for the VCC/GND/A/A_/B/B_.
03:13 PM Bleepshop: And of course the LED.
03:14 PM pcw-home: Yes and 0V needs to connect to field power common. I guess you could connect the LED to a 7I76E output
03:15 PM pcw-home: (to indicate when the MPG was active=jog enabled)
03:17 PM XXCoder: big pipe wrench https://youtu.be/MQ9AvvrXhaQ
03:23 PM * JT-Woodshop used to operate one of those chain wrenches
03:23 PM XXCoder: jt strong
03:23 PM XXCoder: I doubt I can lift those chains, let alone whole thing
03:23 PM XXCoder: kidding, I bet you was in team
03:23 PM JT-Woodshop: we used to hang it and use the draw works to pull it
03:24 PM JT-Woodshop: when we didn't have the proper jaws for the tongs we used the chain wrench
03:30 PM JT-Woodshop: https://www.youtube.com/watch?v=97aI-JS1fgg I used to do that offshore
03:31 PM JT-Woodshop: but that guy is really slow
03:32 PM JT-Woodshop: https://www.youtube.com/watch?v=-quDGwXt048
03:32 PM JT-Woodshop: that's what it was like when I worked offshore
03:33 PM XXCoder: ow heh
03:33 PM XXCoder: I wouldnt be able to do that even at my peak health
03:33 PM JT-Woodshop: a lot of chain hands were missing a finger
03:34 PM JT-Woodshop: that's a small rig
03:35 PM JT-Woodshop: sometimes you tripped pipe almost the whole shift
03:35 PM JT-Woodshop: 12 hour shifts
03:35 PM JT-Woodshop: that chain hand is a bit sloppy throwing the chain
04:23 PM Tom_L: pcw-home is probably the only one that can pull a fast one on pcw-home
04:25 PM travis_farmer[m]: nap didn't help... eyes are still tired...
04:26 PM Tom_L: JT-Woodshop, that's a young man's job
04:29 PM JT-Woodshop: yup
04:30 PM JT-Woodshop: when I worked off the west coast of Africa I was a motorman... a much easier job and paid better than a floorhand
04:31 PM JT-Woodshop: I tried being a driller once but it's too boring and too much responsibly for other folks lives
04:31 PM Tom_L: i wouldn't wanna be that guy at the top of the pipe
04:31 PM * JT-Woodshop is selling his 24' extension ladder... my climbing days are gone
04:31 PM JT-Woodshop: I did that for years in the gulf in a standard derrick
04:31 PM XXCoder: dont need to fix ceilings etc?
04:33 PM Tom_L: do they pump mud in those?
04:33 PM travis_farmer[m]: only 24'? i have a 40' that will let you climb up around corners... (wind took it one day, has a bit of a curve)
04:34 PM JT-Woodshop: https://en.wikipedia.org/wiki/Derrick#/media/File:Derrick.JPG
04:34 PM Tom_L: iirc they do that on land
04:34 PM JT-Woodshop: yep they use drilling mud to bring the chips up to the surface
04:35 PM JT-Woodshop: a standard derrick is huge
04:35 PM Tom_L: i've seen them around here from time to time
04:36 PM JT-Woodshop: on land?
04:36 PM travis_farmer[m]: i have a cousin named Derrick... he is a little over-weight, but not huge...
04:36 PM Tom_L: we have quite a bit of oil around here
04:36 PM JT-Woodshop: usually on land they use a truck rig and it has a telescoping derrick
04:36 PM Tom_L: used to have derby refinery here but they tore it down
04:36 PM Tom_L: yeah
04:37 PM * JT-Woodshop work on a truck rig for a couple of years
04:37 PM Tom_L: now there's one about 25 mi from here
04:37 PM JT-Woodshop: worked even
04:37 PM travis_farmer[m]: well, if i am to be ignored, i may as well leave...
04:37 PM Tom_L: they have an oil museum but i've never been
04:38 PM Tom_L: http://www.kansastravel.org/kansasoilmuseum.htm
04:39 PM Tom_L: i've seen the platforms in the gulf
04:40 PM Tom_L: her dad worked on a crab boat around Alaska for a while
04:41 PM Tom_L: another grueling job
04:41 PM XXCoder: https://www.youtube.com/watch?v=3qRbzyVB8ew
04:41 PM XXCoder: nice intro to materials
04:46 PM markgonz: hey friends, quick question, I am getting familiar with the axis gui
04:46 PM markgonz: I want to edit the default engraving linuxcnc program ans change the scale
04:46 PM markgonz: how I am supposed to edit the code?
04:47 PM JT-Woodshop: File > Edit
04:49 PM markgonz: I tried earlier but told me I should save first, and even then it dont let me modify
04:50 PM markgonz: it should let me edit directly at the bottom where I can see the code right?
04:52 PM JT-Woodshop: hmm it may be in a read only location which I never understood the reason for doing that
04:52 PM JT-Woodshop: prob save as
04:53 PM JT-Woodshop: I don't have linuxcnc on this pc but I can look in a few on my machine shop pc
04:59 PM markgonz: so I tried to open the saved g code to edit outside of linuxcnc and try a text editor of some sort
04:59 PM markgonz: what would be the right program for that>
04:59 PM markgonz: ?
04:59 PM markgonz: because there seem to be no default to open .ngc
05:02 PM JT-Shop: are you on debian?
05:02 PM JT-Shop: if so use pluma
05:02 PM markgonz: yes Im on debian
05:02 PM markgonz: thanks I will try!
05:02 PM JT-Shop: yup right click on the .ngc file and open with pluma

05:17 PM * Tom_L is watching pere
05:34 PM vetsin: if my input is set like `net joint-select-a <= ...` does that mean i wnat to set `net axis-select-x => joint-select-a` or are there aliases? the default was `=> axis.x.job-enable` which is confusing
05:39 PM vetsin: or rather i should ask if theres doc on the builtin signames like `motion.motion-enabled`
05:58 PM Tom_L: depends quite a bit what you're looking for specifically

08:29 PM vetsin: setup is 5us, presumably, but hold is...?
09:18 PM pcw-home: just set them large (say 20 usec) there is no actual penalty for having large setup/hold times
