01:11 AM jpa-: mrec: i've found that it works better if the joint limits are a bit more lax than the axis limits
01:27 AM randy: morning
01:48 AM Deejay: moin
03:42 AM mrec: great ... z axis powersupply replaced and the undervoltage problem is gone.
04:18 AM CaptHindsight[m]: https://www.automationtechnologiesinc.com/products-page/motion-controllers/c94-multifunction-board anyone know which microcontroller they use in these?
04:19 AM CaptHindsight[m]: price varies greatly by which firmware comes installed
04:29 AM Tom_L: morning
04:30 AM CaptHindsight[m]: I know I'm working late when tom and JT are getting up
04:31 AM Tom_L: probably just occupying space at this point if you're still up
04:32 AM CaptHindsight[m]: it's not back breaking work
04:33 AM CaptHindsight[m]: more mind bending
04:46 AM JT-Cave: morning
07:02 AM perry_j1987: morning
08:05 AM perry_j1987: https://emco.co.uk/wp-content/uploads/2016/02/milling_machine_Concept_Mill_55_EN-1.pdf small work envelope but looks like nice unit
08:10 AM jpa-: probably pretty expensive for what it does, but it does make sense for the training purposes it is meant for
08:17 AM perry_j1987: can pick em up used for under 5k sometimes
08:17 AM perry_j1987: doesnt seem to bad for something with a tool changer at least
08:18 AM jpa-: yeah, that's a quite reasonable price
08:20 AM perry_j1987: think it would make a fun conversion project
08:26 AM JT-Shop: this is a fresh fishing text message "I noticed that cnc machines llc didn't have a web site so I created one for you reply yes to see it"
08:27 AM JT-Shop: number blocked
08:31 AM perry_j1987: lol
08:35 AM perry_j1987: maybe they'd have better luck if they were trying to contact you about your car's extended warranty
09:02 AM JT-Cave: my rule is if someone contacts me that I don't know I never reply, I never answer a call from a number not in my contacts
10:57 AM Birdman3131[m]1: Any ok cheap 4th axis addons? Not looking to do so now but I am eyeballing doing so in the future although i already have a small bed so not positive I wanna sacrifice much space. https://machinesused.s3.amazonaws.com/1/2021/6/large/ac597fa7dfd266a863bd76f6570bdf78 Is the same model I am retrofitting.
11:44 AM Rab: Birdman3131[m]1, this seller has been offering these for a long time: https://www.ebay.com/itm/191714031261
11:46 AM Rab: I believe the quality is pretty good--name brand industrial stuff--and IIRC people have successfully mated them up with e.g. little 3" chucks. But they are appropriate for like a Taig, or Sherline as the listing mentions. Not sure if that's beefy enough for your work.
11:48 AM perry_j1987: i remember looked at those
11:48 AM perry_j1987: ended up not going with it cause no through hole capacity
11:49 AM perry_j1987: i run barstock through my 4th axis
11:50 AM perry_j1987: for small machines it could be pretty cool little setup with a rotary pallet system
11:50 AM perry_j1987: give you 4x table space etc
11:53 AM CaptHindsight[m]: https://www.ebay.com/itm/294357099233 probably 100x better accuracy
11:55 AM CaptHindsight[m]: or https://www.ebay.com/itm/114722760962
11:55 AM Rab: CaptHindsight[m], could be, but that's precision optical bench stuff. Not much stronger.
11:58 AM CaptHindsight[m]: Rino Rotary Stage: Part# : ONDO 3454 , Ratio: 30-1 , 360 Degree (Made in USA ) , maybe
11:59 AM jpa-: https://eur.vevor.com/wood-engraving-machine-c_11142/cnc-router-rotational-rotary-axis-4-jaw-durable-aluminum-alloy-high-quality-p_010765761673 i have been considering this
11:59 AM jpa-: the step size is quite large though
12:00 PM CaptHindsight[m]: https://www.youtube.com/watch?v=LFopy-dhAk4
12:02 PM CaptHindsight[m]: jpa-: belt driven
12:03 PM jpa-: that too
12:13 PM perry_j1987: jpa- thats the one i ended up with
12:13 PM perry_j1987: cause ithad the largest through hole i could find at the time heh
12:17 PM -!- #linuxcnc mode set to +v by ChanServ
12:21 PM CaptHindsight[m]: I haven't found a picture of the inside of the Rino Rotary Stage
12:21 PM CaptHindsight[m]: maybe a worm gear
12:23 PM perry_j1987: https://www.youtube.com/watch?v=tvs3vVylEPs
12:23 PM jpa-: BS-0 would have a 18mm through hole and worm gear, plus tilting
12:24 PM perry_j1987: CaptHindsight[m] def a worm gear
12:24 PM Tom_L: CaptHindsight[m], do you know the difference between --bootloaders syslinux or --bootloaders grub-efi?
12:25 PM CaptHindsight[m]: https://www.ebay.com/itm/275432831771 lot of 6
12:25 PM Tom_dev: https://man.cx/lb_config(1)#comments
12:25 PM Tom_L: point of reference
12:27 PM CaptHindsight[m]: Tom_L: what are you trying to do?
12:28 PM Tom_L: build that iso as either a livecd or at least an armhf bootable image
12:28 PM Tom_L: more likely armhf bootable image file
12:29 PM CaptHindsight[m]: oh, ntulinux offered to help you
12:29 PM CaptHindsight[m]: but he's leaving right now
12:29 PM CaptHindsight[m]: Tom_L: do you have an iso already or tarball he can download?
12:31 PM roguish[m]: hey who does the log? is it stored somewhere reachable? i need to look back a few months for a discussion.....
12:31 PM Tom_L: depends
12:31 PM Tom_L: what do you wanna know?
12:33 PM Tom_L: roguish[m], would it be on libera or before that?
12:33 PM CaptHindsight[m]: EFI is the bloatware loader
12:33 PM Tom_L: ok
12:33 PM CaptHindsight[m]: an OS as the bootloader
12:33 PM Tom_L: roguish[m], key search word?
12:34 PM CaptHindsight[m]: so you get all the features of an OS before you load your real kernel
12:34 PM roguish[m]: it was last fall, like late august or early sept
12:34 PM CaptHindsight[m]: since EFI is an OS
12:34 PM Tom_L: i got bookworm on rpi4 last evening
12:34 PM roguish[m]: got the index. i'll plow thru it
12:34 PM CaptHindsight[m]: but they didn't market it as an OS
12:34 PM Tom_L: roguish[m], what are you looking for?
12:35 PM Tom_L: i can find it quicker probably
12:35 PM roguish[m]: I bitched about a bill from USCF. and now I would like to know that date......
12:36 PM roguish[m]: if you are able to search, just use
12:36 PM roguish[m]: UCSF.
12:36 PM Tom_L: not in my local log on libera
12:37 PM Tom_L: Aug 22 12:56:03 <Roguish> this is UCSF. supposed to be one of the best in the US.
12:37 PM roguish[m]: DUDE, thanks. that's it.
12:40 PM roguish[m]: thanks😎
12:41 PM perry_j1987: c'mon UPS truck i want my 5c chuck! heh
12:46 PM CaptHindsight[m]: https://www.automationtechnologiesinc.com/products-page/motion-controllers/c94-multifunction-board wondering which microcontroller this uses
12:46 PM roguish[m]: Tom_L: I just found a way to add the date,month,year to the datestamp in hexchat..... can that be done here????
12:47 PM CaptHindsight[m]: price varies by the number of axis is supports, they load it with different firmware so the price varies from $200-1200
12:48 PM CaptHindsight[m]: not programmed it is $18
12:52 PM CaptHindsight[m]: https://www.cnc4pc.com/c94-multifunction-board-b.html
01:03 PM CaptHindsight[m]: somebody mentioned PIC32MZ
01:07 PM Rab: Their "UCxx Utility Software" includes ftd2xx.dll, suggesting a FTDI USB-to-serial interface, which might be (pretty weak) evidence against PIC32MZ.
01:08 PM Rab: (Unless they opted not to use an onboard USB stack for code simplicity.)
01:10 PM Tom_L: roguish[m], to the logs?
01:10 PM Rab: UCxxx_utility.exe just seems to scan the local network for UCxx devices, so I'm not sure how ftd2xx.dll comes into play.
01:13 PM CaptHindsight[m]: Rab: https://www.forum.cncdrive.com/viewtopic.php?f=19&t=1783&start=10#p16035
01:13 PM Rab: CaptHindsight[m], I think you may have been fooled by their shopping cart. The DIN rail support option is $17.80, the board is $108, programmed it's $233.
01:13 PM Rab: CaptHindsight[m], I see.
01:14 PM CaptHindsight[m]: the pics online appear to have a PIC as well
01:17 PM CaptHindsight[m]: https://www.cnc4pc.com/pub/media/catalog/product/cache/a64f68afc533dfcdca22c66aa6987734/u/c/uc300eth_1_.jpg
01:42 PM miss0r2: I just spend 4 hours grinding the morsetaper in the tailstock of an old beat up lathe. Apparently the client loved that old thing so much, that he wanted it restored.
01:42 PM miss0r2: Looking at the state of the morse taper, one would not think that he loves it, but hey. Its work :)
01:58 PM Rab: perry_j1987, 3.75" through hole! https://www.ebay.com/itm/224951941463
01:59 PM Rab: (Belt driven)
01:59 PM perry_j1987: lol
02:00 PM Rab: Not bad for a thing, on eBay, in 2022.
02:04 PM perry_j1987: any moment i should be getting my new 5c chuck from UPS
02:06 PM roscogamer[m]: Neat
02:07 PM roscogamer[m]: Also weird ish question
02:07 PM roscogamer[m]: Can I use the Mesa cards as a plc so program logic into it
02:09 PM roscogamer[m]: Cus that whould save me from buying a dedicated plc
02:09 PM roscogamer[m]: It's all now speed stuff so it doesn't need to be super fast
02:09 PM roscogamer[m]: It's mainly just for monitoring sensor values
02:10 PM ZincBoy[CAON][m]: Yes, you can use ClassicLadder to do ladder logic PLC type programming
02:10 PM roscogamer[m]: Like if air is on of if coolant if gull or empty
02:10 PM ZincBoy[CAON][m]: I just do everything as C comp files though as I hate ladder logic.
02:10 PM roscogamer[m]: Same
02:10 PM roscogamer[m]: Oké good to know
02:10 PM roscogamer[m]: Guess I'll scrap the plc from my parts list
02:12 PM roscogamer[m]: Or does this kinda thing have a big influence on the workings of the mesa
02:12 PM roscogamer[m]: Like reduce max speed I can drive the motors at
02:13 PM ZincBoy[CAON][m]: My mill has 2x 7i84 boards and a 7i77 board with most of the IO used.
02:13 PM ZincBoy[CAON][m]: It has no real impact on linuxcnc performance.
02:14 PM ZincBoy[CAON][m]: If you went really crazy and tried to do too much in real-time then you might have problems. For stuff like that, you can do it as a non-real time component.
02:15 PM ZincBoy[CAON][m]: I replaced all of the PLC functions in my mill linuxcnc and mesa card IO. Works great and is easier to debug when it is all in one place.
02:15 PM roscogamer[m]: Awsome
02:16 PM roscogamer[m]: My exact thinking
02:16 PM roscogamer[m]: Tho if I were to run out of io on my Mesa 7i84 and 7i96s
02:16 PM roscogamer[m]: Can I add more
02:16 PM roscogamer[m]: No right?
02:17 PM tcurdt-: At least the 7i96s has IDC connector for a daughter board
02:17 PM roscogamer[m]: Since it only got one expansion header it
02:17 PM tcurdt-: Ah ... misread
02:18 PM ZincBoy[CAON][m]: Yes, you can go 7i96 to 7i74 to create more channels of RS422 IO for sserial expansion cards. This is kind of what I did.
02:19 PM roscogamer[m]: Ohh
02:19 PM roscogamer[m]: So the overpriced switch
02:19 PM roscogamer[m]: Xd
02:19 PM ZincBoy[CAON][m]: I have a 7i98 that goes to a 7i77 and 7i96
02:20 PM roscogamer[m]: Oké neat
02:20 PM roscogamer[m]: Thanks guys
02:20 PM roscogamer[m]: This is ngl one of the most helpful community's I have seen is cuite some time
02:21 PM roscogamer[m]: s/cuite/quite/
02:21 PM ZincBoy[CAON][m]: The 7i96 goes to 2x 7i84 and 2x 7i73 boards.
02:22 PM ZincBoy[CAON][m]: There are some limits depending on the host FPGA on how many sserial channels you can have. Using the 7i98, I can only have 6 channels on the 7i96 with the 7i77 installed.
02:24 PM perry_j1987: what in the world are you all running to need so much iO
02:24 PM perry_j1987: you got your MILL checking if you've had coffee before running and it fetches you a cup or something heh
02:28 PM ZincBoy[CAON][m]: It is a machining center with a tool changer. Needs lots of IO.
02:29 PM * JT-Shop has to remake a part 1/8" longer... close but no cigar
02:30 PM ZincBoy[CAON][m]: That is what the welder is for, isn't it? 🙂
02:33 PM JT-Shop: it's a 1" x 2" x 1/8" piece of 6061 with 8 0.116" holes
02:33 PM ZincBoy[CAON][m]: Well, that might be a bit tougher then
02:52 PM Birdman3131[m]1: Just send the intern after a metal stretcher.
02:54 PM JT-Shop: I hollered for one but nobody showed up
02:59 PM Tom_dev: P: Build completed successfully
03:00 PM Tom_dev: now to see about the boot condition of it
03:06 PM JT-Shop: 30 minutes to size the material, change the CAD, do CAM over for a 30 second part
03:07 PM roscogamer[m]: Yes
03:07 PM roscogamer[m]: I need all the io
03:08 PM Tom_L: JT-Shop, what part?
03:08 PM roscogamer[m]: Tbh I'm making my cnc manual tool change rn
03:08 PM roscogamer[m]: But in the future I wanna go atc
03:09 PM roscogamer[m]: And I kinda want it to be like a vmc
03:09 PM roscogamer[m]: So error codes for everything
03:11 PM JT-Shop: just a little part that holds a tiny gripper
03:19 PM JT-Shop: well it took 55 seconds to make the part
03:38 PM Birdman3131[m]1: Ive been eyeballing methods for making an auto tool changer on mine. But thats future me.
03:39 PM perry_j1987: why's it feel like the uPS guy stops off for a beer or something on days i order somethign to be delivered
03:58 PM Birdman3131[m]1: Thats why you bribe them with a cold beer. No need to stop off elsewhere then.
04:03 PM perry_j1987: ah they are here
04:05 PM CloudEvil: yay
04:07 PM perry_j1987: On my way! to shop heh
04:20 PM justache is now known as justDeez
04:35 PM perry_j1987: oddly scooter didnt want to run had to take vehicle
04:35 PM perry_j1987: at shop now
04:38 PM perry_j1987: initial inspection these bostar 5c chucks look very nicely machined
04:38 PM perry_j1987: scroll feels grit free
04:41 PM CloudEvil: :)
04:42 PM CloudEvil: I have not as yet inspected my 5C chucks I got from amazon a year ago.
04:42 PM perry_j1987: lol
04:42 PM perry_j1987: that one of those insane cheep deals
04:42 PM perry_j1987: someone in here got a while back mispriced or something
04:42 PM CloudEvil: They were $30. (misprice, I suspect. They are about the right shape, and covered in grease and shiny, which is about what I expect for that as a minimum)
04:43 PM perry_j1987: what brand
04:45 PM perry_j1987: hmm it appears i have to turn the back side of the faceplate registraiton too
04:45 PM CloudEvil: Highest quality Fafeicy
04:45 PM perry_j1987: thought the backside was suppose to be fully done
04:45 PM perry_j1987: measures 38.5-ish needs to be 39
04:46 PM JT-Shop: how are you going to turn it bigger?
04:47 PM CloudEvil: Clamp a collet on a bar?
04:48 PM perry_j1987: i was going to thread it on backwards and put an indicator in there to see how concentric it is just on the threads lol
04:48 PM perry_j1987: figure i'll get rid of all the bonehead ideas right away
04:52 PM perry_j1987: cant do that CloudEvil once i get the backplate mounted then i can turn the front surfaces to mate with the chuck
04:55 PM perry_j1987: hmm
04:55 PM perry_j1987: looks like .12mm with an indicator on it
04:55 PM perry_j1987: just threaded on
05:15 PM perry_j1987: gah lost internet
05:15 PM perry_j1987: ok question i just looked up a thread comparison chart
05:15 PM perry_j1987: it looks like m39x4 is comparible to 1-1/2x8 imperial?
05:36 PM CaptHindsight[m]: JT-Shop: build up metal with a MIG, then turn
05:41 PM JT-Shop: but he didn't say that
05:42 PM CloudEvil: Now I'm wondering how well solder would work.
05:43 PM JT-Shop: works great to fasten two copper wires together
05:50 PM JT-Shop: hopefully tomorrow will go smooth and Friday I can go for a ride with the wife and celebrate
05:50 PM perry_j1987: there we go i seem to ahve internet again out here lol i can see talk in the channel
05:50 PM perry_j1987: its always going up and down out here lol
05:51 PM perry_j1987: if i thread this backplate on backwards and open up the bore a bit so it fits snugly on the spindle seat that shouldnt introduce any issues
05:51 PM perry_j1987: cause it would be turned while threaded on so if i flip it back around it'll thread on and fit i think...
05:52 PM perry_j1987: all the surfaces on the front im turning anyways to be concentric for the lathe
05:52 PM perry_j1987: i just need some verification that i wouldnt be creating a cam lock by doing it this way on the backside lol
05:54 PM JT-Shop: damn looks like 2023 before starlink is in my area
05:54 PM XXCoder: aw
05:55 PM CaptHindsight[m]: anyone ever seen a vertical bar feeder?
05:55 PM JT-Shop: almost the whole southeast is waiting
05:56 PM JT-Shop: https://www.starlink.com/map
05:56 PM CaptHindsight[m]: need to feed bars <10mm dia into a machine in a vertical position vs horizontally
05:57 PM XXCoder: LOL im right in middle of small "waiting" cluster in wa
05:57 PM CaptHindsight[m]: JT-Shop: yeah, they are building up the number of sats, they just announced fixed mobile service
05:58 PM CaptHindsight[m]: I don't know if we will ever get mobile mobile Starlionk
05:58 PM JT-Shop: fixed mobile as in cell phone?
05:58 PM perry_j1987: will speed things up once they get starship flying
05:58 PM JT-Shop: XXCoder, Tacoma?
05:59 PM XXCoder: yup
05:59 PM perry_j1987: im ready to start cutting if someone can chime in and say if its a stupid idea or not lol
05:59 PM JT-Shop: no photos, no comments
06:00 PM perry_j1987: i cant photo my phone is up a 20' ladder in the rafters so i can get internet lol
06:00 PM JT-Shop: lol
06:00 PM perry_j1987: but basically the back bore on this faceplate is slightly too small
06:00 PM CaptHindsight[m]: JT-Shop: fixed mobile is for RV's and marine, you just can't use it while moving but your location can change
06:01 PM JT-Shop: ah that makes sense now
06:01 PM perry_j1987: im figuring i can just thread it on backwards so i can access the bore and open it up slightly just off the threads and jammed the face up to the shoulder
06:01 PM CaptHindsight[m]: I wonder if you have an RV and drive to Georgia if you still get service?
06:02 PM JT-Shop: I got an email offering me a rv dish from starlink
06:04 PM JT-Shop: maybe I should have gotten it and attached it to my 1956 Ferguson F40
06:06 PM JT-Shop: hot topic on the dev mailing list 2.8 and 7i96S
06:09 PM CaptHindsight[m]: ZincBoy[CA, ON]: I'd rather use Python than ladder
06:10 PM Tom_L: JT-Shop, has a patch been merged to 2.8 for it?
06:11 PM JT-Shop: a new release is in the works for 2.8.4 to support the 7i96S
06:11 PM Tom_L: oh cool
06:12 PM JT-Shop: I think I inspired it :)
06:13 PM Tom_L: alot of activity recently
06:13 PM Tom_L: i wish i knew more about this stuff
06:13 PM JT-Shop: a whole lot of activity for sure
06:13 PM Tom_L: i think maybe adding matrix and discord helped
06:14 PM Tom_L: at least here
06:14 PM JT-Shop: yep
06:14 PM JT-Shop: empty glass time to call it a night
06:37 PM perry_j1987: hey there we go got the backplate fitted
06:37 PM perry_j1987: now i can turn it down for the 5c chuck finally
06:37 PM CaptHindsight[m]: nope, no vertical bar feeders anywhere
06:38 PM CaptHindsight[m]: perry_j1987: I thought that you had to increase its size
06:38 PM perry_j1987: the hole in the back i did
06:38 PM CaptHindsight[m]: "measures 38.5-ish needs to be 39 "
06:39 PM perry_j1987: theres a 1-1/2 threads and a shoulder
06:39 PM perry_j1987: the hole in the backplate was slightly too small to fit over the spindles shoulder
06:39 PM CaptHindsight[m]: ah remove vs put metal
06:39 PM perry_j1987: so i threaded the backplate on backwards and the face was flat to the shoulder and i bored it out
06:39 PM perry_j1987: now its on the right way around and i can turn the front features
06:40 PM perry_j1987: going to have to move my qctp back to reach it though
06:41 PM CaptHindsight[m]: Tom_L: maybe the fear of Gentoo got the devs moving
06:46 PM Tom_L: :)
06:48 PM perry_j1987: lol gotta take off this limit switch bracket so i can get close enough to turn the backplate
07:31 PM perry_j1987: just about done fitting this chuck
07:36 PM perry_j1987: ok mounted
07:37 PM perry_j1987: dial indicator on inside taper of the 5c bore shows .04 movement
07:44 PM perry_j1987: bet i can get it better
07:44 PM perry_j1987: .04mm

09:47 PM CaptHindsight[m]: Rpi4's cost more now
09:47 PM Tom_dev: so does gas
09:52 PM Tom_L: CaptHindsight[m], gonna pull an all nighter again??
09:52 PM Tom_L: :)
10:33 PM CaptHindsight[m]: Tom_L: too many this week already
10:41 PM CaptHindsight[m]: https://pine64.com/product/quartz64-model-b-4gb-single-board-computer/ this might be the best ARM board for LCNC for the next 6 months
10:41 PM CaptHindsight[m]: https://wiki.pine64.org/wiki/Quartz64
10:43 PM CaptHindsight[m]: some devs have left this group since Manjaro is the favored distro https://wiki.pine64.org/wiki/Quartz64#Manjaro_ARM
