01:36 AM Deejay: moin
01:47 AM lcnc-relay: <TurBoss@> good morning
02:07 AM pere: andypugh: hi.
03:53 AM lcnc-relay: <Lucid Nonsense@> Mornin
03:57 AM Tom_L: morning
04:16 AM RifRaf: mornin Tom_L
04:49 AM -!- #linuxcnc mode set to +v by ChanServ
07:01 AM Tom_L: skunkworks, i think i found a case that will house the nvme
07:02 AM Tom_L: with a full size ssd
08:04 AM lcnc-relay: <skunkworks@> really? link?
08:24 AM -!- #linuxcnc mode set to +v by ChanServ
08:43 AM lcnc-relay: <Lesliet@> mornin
09:10 AM * rdtsc-w had the usual amount of sleep, but sure thinks more would have helped
09:11 AM lcnc-relay: <Lesliet@> I was just zonked yesterday after work and after-work chores
09:11 AM lcnc-relay: <Lesliet@> crashed early, no interweebs
09:12 AM xxcoder: I hate it when I am just sick enough that I cant properly sleep
09:12 AM lcnc-relay: <Lesliet@> new vinyl cutter that I intend to cut gaskets with arrived, only got as far as opening the box to verify not damaged, and not a brick in a box
09:12 AM xxcoder: only 6 hours sleep
09:12 AM lcnc-relay: <Lesliet@> erf
09:15 AM Tom_L: skunkwork, https://www.amazon.com/dp/B0DL2DFZQ7
09:16 AM Tom_L: i'll have one Saturday and i think the nvme board we got will also fit
09:16 AM Tom_L: i got a spare just in case it will
09:16 AM Tom_L: their nvme hat doesn't come with a ssd
09:18 AM lcnc-relay: <Lesliet@> _note to self, check here before final purchase of π_
09:19 AM xxcoder: thats pretty cool case
09:19 AM Tom_L: bottom mout nvme
09:20 AM Tom_L: if i do put one on the mill i want it enclosed some how
09:22 AM Tom_L: got another one of these to see if it will fit https://www.amazon.com/dp/B0F389CXSX
09:23 AM Tom_L: if not, i needed another ssd anyway
09:24 AM Tom_L: the only reason i see that it wouldn't would be where the ribbon is placed
09:24 AM Tom_L: might be too close to the case
09:24 AM Tom_L: the one with the case is recessed a bit
09:29 AM lcnc-relay: <skunkworks@> yes - I have found that one.. I thinkt the cases that I tried to print fit that nvme holder
09:29 AM lcnc-relay: <skunkworks@> I read it as - I found a case that fits those... lol
09:29 AM Tom_L: i kinda think the ribbon on the one we got will get in the way
09:29 AM Tom_L: but
09:30 AM Tom_L: the case comes with the board
09:31 AM lcnc-relay: <skunkworks@> oof - long morning. see your case link now.
09:31 AM Tom_L: got another waveshare touch screen & wall mount coming for it in case it does work out for the mill
09:32 AM lcnc-relay: <skunkworks@> i have never played with a touch screen and linuxcnc. I think the plasma would be a nice place to have a touch screen
09:32 AM Tom_L: i think i finished up my touch tp3-touch ui yesterday so i may give it a go
10:08 AM roycroft: i tried out linuxcnc on a touchscreen laptop a while back
10:08 AM roycroft: my conclusion was that it would be useful, but needed a bigger screen
10:09 AM roycroft: 17" would be the minimum i'd want to use, and preferably 21"
10:09 AM Tom_L: the ones i got are 15"
10:09 AM Tom_L: 1080
10:09 AM roycroft: maybe my fingers are too fat
10:10 AM roycroft: the laptop has a 15" display
10:10 AM Tom_L: you can make the touch widgets bigger
10:10 AM roycroft: yes, simplifying the layout might help
10:10 AM roycroft: simplify and enlarge
10:10 AM Tom_L: i've never owned one but so far i'm pleased
10:12 AM lcnc-relay: <skunkworks@> What are you using for a screen?
10:13 AM Tom_L: https://www.amazon.com/dp/B07QXKKHRF
10:13 AM Tom_L: similar to the one rdtsc got but his was pannel mount
10:15 AM Tom_L: i've been using it and the regular screen for dual monitors while making the gui
10:16 AM Tom_L: that and some crappy little wall mount for the shop mill
10:17 AM xxcoder: if I recall theres kits to turn regular montiors to touchscreens too
10:17 AM Tom_L: the current one doesn't work with the rpi5 even with an adapter
10:17 AM Tom_L: i wanted stuff i felt confident would work
10:18 AM xxcoder: thats always good idea
10:18 AM Tom_L: no time for returns bs
10:22 AM roycroft: those kits generally don't work well, xxcoder
10:23 AM xxcoder: ok
10:23 AM roycroft: well, i can't say that for sure now, since i haven't tried any since the crt days
10:23 AM roycroft: but they did not work well then
10:24 AM rdtsc-w: have a HP dual-core AMD system with infrared touch - that thing is supported by (very) old kernels only
10:24 AM roycroft: the biggest problem was that the sensor grid could not be mounted close enough to the screen, and that caused a lot of parallax problems
10:25 AM roycroft: but perhaps with flat screen led displays that problem has been solved
10:26 AM xxcoder: if I was designing touchscreen for machine, I would make it not capactive type. so you could touch it with gloved hand and it will still work
10:27 AM Tom_L: we have very few employees in this shop :)
10:27 AM Tom_L: <-
10:27 AM roycroft: just the boss and the boss' real boss - his wife? :)
10:29 AM Tom_L: i should update the tp3 pics
10:31 AM lcnc-relay: <skunkworks@> most of the time I am using nitril gloves. they seem to work ok with capasitive. but yes - usually you want resistive expecially if there is a chance oil/liquid drops can get on the screen
10:31 AM lcnc-relay: <skunkworks@> (but I would probably buy a capacitive)
10:32 AM roycroft: a styluc would help
10:32 AM roycroft: stylus, rather
10:32 AM roycroft: it would also help with the fat finger problem
10:32 AM roycroft: but it would probably be annoying
10:42 AM Tom_L: http://tom-itx.no-ip.biz:443/~webpage/cnc/JT-SHOP/flexgui/Rpi5/
10:43 AM Tom_L: you can map leds in postgui hal now
10:43 AM Tom_L: the probe page led works in conjunction with the probe enable on the main page
10:43 AM Tom_L: for example
10:45 AM Tom_L: demo of flood / mist https://www.youtube.com/watch?v=5ng1bn63PGQ
11:08 AM lcnc-relay: <wrickert@> I just picked up one of these from my local college surplus for $15! Super excited to hook that up tonight!
11:08 AM lcnc-relay: <wrickert@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/NVAApYnUwQGMltfzYvDpncKu/gUUb63Xd3jI/s-l400.png
11:10 AM xxcoder: nice
11:22 AM roycroft: $2600 for the transmission
11:22 AM roycroft: flex plate and torque converter need replacement
11:22 AM Tom_L: ouch
11:22 AM roycroft: that's not good, but it's better than $5500
11:24 AM roycroft: it only depletes half the slush fund
11:25 AM roycroft: so i only need to slush up half as hard to replenish it
11:25 AM Tom_L: better get another slushie
11:25 AM roycroft: i'm having them replace the rear main seal on the engine while the transmission is out
11:25 AM roycroft: that's $170, and included in the $2600 quote
11:25 AM xxcoder: hopefully it snows soon so you can get more slush
11:25 AM Tom_L: that's a no brainer
11:26 AM roycroft: they say the seal looks good, but the engine has 385,000 miles on it
11:26 AM xxcoder: yeah smart move to replace cheap seals while its out
11:26 AM roycroft: seems like a good time to just go ahead and replace it
11:26 AM roycroft: it should be done tomorrow, but they are closed on fridays
11:26 AM roycroft: so i
11:26 AM roycroft: shall probably get it back on monday
11:27 AM roycroft: i did some checking, and i can catch a bus from here to town at 1pm, and get to the shop by about 3:30, so that's probably what i'll do
11:27 AM roycroft: i could drive down to get it, but then my car would be stuck in town
11:28 AM roycroft: and i have no way of towing the car back without renting a dolly, which i'd have to take back to town when i'm done
11:28 AM roycroft: or pay a huge one-way rental fee
11:28 AM roycroft: i think a car dolly is $25/day round-trip, but $75 one-way
11:29 AM roycroft: anyway, i'm glad this is all settled now
11:29 AM roycroft: i've been stressing over the cost, and while i'm not excited about what it's going to cost, it could be a lot worse
11:30 AM roycroft: the last time this happened was on my '75 chevy pickup
11:31 AM roycroft: my solution then was to swap the automatic transmission for a muncie 4 speed
11:31 AM roycroft: which i did in the middle of the rainy season on my driveway
11:31 AM roycroft: i'll never do something like that again
11:31 AM roycroft: although in the end it was a significant upgrade, imo
11:32 AM roycroft: but i had to swap the bell housing, transmission, drive shaft, middle of the floor pan in the cab, and steering column
11:33 AM roycroft: since modern transmissions have a bunch of sensors and the like on them, it would probably be much more difficult to do the swap on this vehicle
12:01 PM lcnc-relay: <RRAMAGE@> I'm in a little bit of a pickle here, planning on re-controlling my roland milling machine to linuxcnc. It uses DC servo motors. The power for the servos is handled by the transformers on the left side of the compartment, but the servo driving seems to be done entirely on the board on the right hand side. I had been planning on replacing that board with my mesa 7176e, but it seems that with the servo drives integrated into the...
12:01 PM lcnc-relay: ... mills FPGA card I need to come up with an open source or general purpose servo drive unit to interface between the step/dir commands issued by the mesa board and the servos themselves. Has anybody had success in that direction? The alternative would be selling off the motors and electronics and doing a much deeper rebuild with clearpath servos or something.
12:01 PM lcnc-relay: <RRAMAGE@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/nYmiVpRuzMESffEKKrLxBogL/6h7eRWXwgRg/roland_brains.jpg
12:02 PM lcnc-relay: <skunkworks@> what are the specs on the servos?
12:11 PM rdtsc-w: Something like the https://www.geckodrive.com/product/g320x-digital-servo-drive/ can do 18-80VDC @0-20A out - not the cheapest, but very good brand
12:38 PM lcnc-relay: <roguish> RRAMAGE@: I use DC brushed motor. a 7i80, and AMC digital drives..... work really good
12:39 PM lcnc-relay: <RRAMAGE@> skunkworks@: The model is the LA052-080E
12:39 PM lcnc-relay: <RRAMAGE@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/uwKTkHZiWyjhImdlwlaZIJjB/fAlyO-rqWns/image0.jpg
12:41 PM lcnc-relay: <skunkworks@> so it is brushless?
12:42 PM lcnc-relay: <roguish> RRAMAGE@: Advanced Motion Controls DigiFlex DPRALTE-020B080 Digital Servo Drive
12:56 PM pere: andypugh: As Signal do not seem to work so well for you, it is perhaps best to tell you here I suspect <URL: https://github.com/petterreinholdtsen/linuxcnc/tree/refs/heads/github-ci-complete-deb-changes-artifact > might provide artifacts closer to what you need to put in a apt repository.
12:58 PM andypugh: Have you tried pushing a tag to your repo to see what happens?
12:59 PM lcnc-relay: <RRAMAGE@> skunkworks@: yes it is brushless
01:02 PM pere: andypugh: no, but I have tried disabling the tag check and observed that it create the artifact structure I wanted.
01:57 PM lcnc-relay: <Lucid Nonsense@> I'm generally fairly positive towards Valve as a company, but releasing a VR headset with monochrome passthrough in 2025 is outdoing Nintendo for outdated hardware
02:59 PM * JT-Shop takes 5 with Dave and watches some early Leo
04:01 PM lcnc-relay: <Lunar@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/WISWFDyaunRsYwpyytRtIaLd/xzrFzGf_2BQ/20251112_164232.jpg

04:01 PM lcnc-relay: <Lunar@> ordinary g76 on the small lathe
04:02 PM lcnc-relay: <Lunar@> API 2⅜ IF
04:02 PM lcnc-relay: taper 2 inches per foot
04:02 PM lcnc-relay: 4 threads per inch
04:02 PM lcnc-relay: <Lunar@> did it with an exit taper move
04:02 PM xxcoder: interesting. looks like nice work
04:03 PM lcnc-relay: <Lunar@> i checked it with an API thread gauge, perfectly formed and all.
04:03 PM andypugh: pere: Sorry, the WiFi on my Linux machine has died. I am a bit stuck for testing the change.
04:03 PM lcnc-relay: <Lunar@> i threaded it at 900 rpm so that my puny low-torque-5000rpm spindle had enough inertia not to stop mid way through the thread
04:05 PM pere: andypugh: sad to hear. should I just push it to master?
04:05 PM lcnc-relay: <Lunar@> Any updates on the g76 taper situation? I have a very old lcnc build...
04:06 PM andypugh: pere: Might as well, I can’t see it doing any harm
04:11 PM pere: andypugh: ok, done.
04:14 PM pere: Lunar@: How do you avoid getting too deep in the hole with the tap?
04:27 PM lcnc-relay: <Lunar@> Which hole? @rdtsc-w This is an external thread 🤔
04:50 PM andypugh: It looks like the 2.5G network was down. Rebooting the router has it back. But not the 5G
04:55 PM andypugh: pere: It looks like the update went into master, so will only affect pushes to master?
05:08 PM lcnc-relay: <skunkworks@> Took another 3820lbs to recycling... This time cast
05:09 PM lcnc-relay: <skunkworks@> They give a little more for #1 cast
05:10 PM lcnc-relay: <skunkworks@> I know now that if the truck gets down to the helper springs - it is between 1.5 and 2 tons
05:34 PM andypugh: pere: Does anything in the new CI check that the release tags are signed?
06:21 PM -!- #linuxcnc mode set to +v by ChanServ
07:22 PM -!- #linuxcnc mode set to +v by ChanServ
07:26 PM rdtsc: We were just talking about FreeCAD-CAM workflow... someone made an end-to-end example https://www.youtube.com/watch?v=zwS5JSRv9R0
07:39 PM lcnc-relay: <skunkworks@> I won't watch it.. I will try to do it - give up and say it is junk.
07:40 PM lcnc-relay: <skunkworks@> probably have another 2 ton of cast in the green polebuilding
08:17 PM Unterhaus_ is now known as Unterhausen
08:17 PM Unterhausen: habitat is building a 3d printed house in our town
08:20 PM lcnc-relay: <skunkworks@> neat
08:20 PM lcnc-relay: <skunkworks@> is it a gantry or a robot arm?
08:21 PM Unterhausen: I guess you would call it a robot arm
08:21 PM lcnc-relay: <skunkworks@> neat - Do you know the company?
08:21 PM Unterhausen: I imagine they are done with the concrete, unfortunately I didn't know about it
08:22 PM lcnc-relay: <skunkworks@> https://www.youtube.com/watch?v=orurGdrlzIs
08:23 PM Unterhausen: x-hab 3d
08:23 PM lcnc-relay: <skunkworks@> really interesting video.. they use a robot arm with a end effector that can compensate for the wiggle of the huge arm
08:24 PM Unterhausen: it's a little bitty thing in comparison to that
08:24 PM Unterhausen: https://www.xhab3d.com/
08:24 PM lcnc-relay: <skunkworks@> they started with a huge gantry - but want to go to a huge arm
08:25 PM lcnc-relay: <skunkworks@> huh - neat. very small compared to the above vide
08:25 PM lcnc-relay: <skunkworks@> video
08:27 PM Unterhausen: I guess the problem with a small machine is keeping track of where the base is sitting
08:39 PM lcnc-relay: <skunkworks@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/SWlIjioxnihkRFBpdtMMxPgM/2zIuP8oSfCc/who_Camera_1763000924282_1.jpg
08:39 PM lcnc-relay: <skunkworks@> the tower cam
08:39 PM lcnc-relay: <skunkworks@> I can't really see it in the valley here
08:40 PM xxcoder: thats cool
08:40 PM lcnc-relay: <skunkworks@> I should grab the whole video
08:42 PM lcnc-relay: <skunkworks@> https://jauriarts.org/_heisenbridge/media/jauriarts.org/NYvtFiDfaZDaaFhjkhOCniKo/zYKMjl2ZamU/who_Camera_1763001695550.jpg
08:42 PM lcnc-relay: <skunkworks@> that is the same view in the daytime
09:12 PM _unreal_: Well I just started milling my marble coasters order
09:12 PM _unreal_: client wants $10
09:12 PM _unreal_: 1-
09:12 PM _unreal_: ugh
09:12 PM _unreal_: 10 coasters. $50 EA
09:13 PM _unreal_: hate switching my machine to wet milling. takes an hour to setup the box
09:13 PM _unreal_: these coasters take about 70min each to make
09:14 PM _unreal_: 2 bits as well a .5mm and a 3.125mm
11:05 PM yaqwsx9 is now known as yaqwsx
