12:00 AM CaptHindsight[m]: I thought building for Debian was automated and simple :/
12:09 AM CaptHindsight[m]: 😫
12:09 AM XXCoder: it should be, but his iso is broken for some reason?
12:09 AM XXCoder: I never built anything like that so uncertain
12:29 AM CaptHindsight[m]: pere
12:29 AM CaptHindsight[m]: Tom_L: congratulation. the issue is probably not fat as such, but the wrong boot loader setup.
12:30 AM XXCoder: you solved it?
12:30 AM CaptHindsight[m]: nope, what pere posted
12:30 AM pere: did not look at it. would have to figure out what kind of boot loader setup rpi4 need first.
01:37 AM randy: morning
01:44 AM mrec: is there a way to home via g-code? I don't want to move the system, the current offset to machine 0 is eg. 62mm at the moment
02:15 AM Deejay: hi
03:07 AM -!- #linuxcnc mode set to +v by ChanServ
03:07 AM -!- #linuxcnc mode set to +v by ChanServ
03:17 AM CaptHindsight[m]: mrec: go to home? or?
03:18 AM CaptHindsight[m]: make the current position Home?
03:19 AM CaptHindsight[m]: mrec: https://forum.linuxcnc.org/20-g-code/25866-how-does-re-homing-in-g-code-work
03:30 AM mrec: seems like it's not possible
03:31 AM mrec: I'd like to set the home position from a remote position (as mentioned I'm doing manual homing on my lathe)
03:31 AM mrec: on the mill I do auto-homing
03:55 AM jpa-: mrec: maybe HOME_ABSOLUTE_ENCODER could be used somehow, though i think you can't do it through g-code and would still have to use HAL connections for it
03:56 AM jpa-: (and POSITION_FILE)
04:49 AM Tom_L: morning
04:53 AM JT-Cave: morning
04:58 AM mrec: I have rebooted the system and properly homed it (I had to do something in win on that dual boot system)
04:58 AM mrec: and finally I got sick of that X axis motor on the lathe ... the new one is much better
05:08 AM Tom_L: mrec, were you the one that got that spindle motor from ali?
05:42 AM solarwind: Hey all, can't really find an answer for this: what's the purpose of dual shield MIG wire?
05:42 AM solarwind: That is, when used in an indoor environment that would work just fine for solid wire
05:43 AM solarwind: When would someone use dual shield instead of bare solid wire? What are the advantages/disadvantages?
05:51 AM mrec: Tom_L: from alibaba the manufacturer you recommended
06:40 AM mrec: does anyone know the reason why jogging is not possible in MDI mode?
06:41 AM jpa-: i can see why it is not possible during MDI command execution, but it's annoying that it doesn't switch to jogging mode automatically afterwards
06:42 AM mrec: I'm updating the xhc pendant now to switch to manual mode automatically
06:42 AM mrec: it doesn't make sense having to go back to the keyboard for switching to manual mode
06:42 AM jpa-: https://github.com/HacklabJKL/sergei_cnc2/blob/main/linuxcnc/config/hal_nocturn.hal#L13-L18 i did similar
06:43 AM mrec: ah you're doing it via config, I'm updating the source blocked keyboard jogging is not a big deal for me but blocked pendant jogging is
06:44 AM Tom_L: mrec, CaptHindsight[m] was asking about them
06:44 AM jpa-: i've been considering disabling keyboard jogging entirely, because i have the separate controller and it is easy to press arrow keys by mistake
06:45 AM mrec: Tom_L: I'm happy about the spindle but the work is not done yet... I need to replace the belt too
06:45 AM mrec: it's way better than before already.
06:45 AM mrec: https://snipboard.io/wBloX6.jpg
06:46 AM mrec: I updated the crossslide .. installed those 3 drills on it
06:46 AM mrec: I want an auto bar feeder and I have an idea how to do that
06:46 AM mrec: keep the same chuck and just tighten it via some geared installation
06:47 AM mrec: I can just measure the torque via an adapter
06:48 AM mrec: thix x axis motor sucked, the new one is 2 mm longer and much better
06:57 AM -!- #linuxcnc mode set to +v by ChanServ
07:08 AM perry_j1987: morning
07:09 AM * JT-Cave wonders why he still has the 1991 GMC S15 Service Manual???
07:10 AM Tom_L: i have a full set as well
07:10 AM Tom_L: s10 though
07:11 AM Tom_L: iirc mine was '92
07:21 AM mrec: got it that was pretty easy
07:21 AM mrec: I'm checking for MDI mode in the xhc driver, if there are jog values to submit to linuxcnc it will temporary switch to Manual Mode
07:22 AM mrec: once submitted it will switch back to Mdi (if it was in Mdi before)
07:23 AM mrec: interesting in case a mdi command is running it can interrupt that ... that might be useful
08:28 AM mrec: G83 Z[#<_startZ>+4] F30 Q0.3 R[#<_startZ>-1]
08:28 AM mrec: anything wrong with that? it's not pecking on the lathe
08:37 AM digger8148[m] is now known as yuiron8148[m]
08:44 AM perry_j1987: i do g83 on the lathe and it pecks
08:45 AM perry_j1987: dont do any bracket stuff though
08:45 AM perry_j1987: just standard gcode and positions
08:46 AM mrec: pecking with the Z axis?
08:47 AM perry_j1987: ya
08:47 AM perry_j1987: do a lot of deep drilling
08:57 AM perry_j1987: got my 5c chuck ordered!
08:57 AM perry_j1987: going to be a happy guy in a few days heh
08:57 AM perry_j1987: already have the collets i need
09:03 AM mrec: it's pecking now thanks
09:04 AM mrec: once the Y axis is configured pecking doesn't work anymore
09:17 AM perry_j1987: odd
09:17 AM perry_j1987: so i did some machining to some parts on this 9x20 techno isel lathe yesterday and got the X travel up to 147mm
09:18 AM perry_j1987: if i take the servo off and machine a bit of it's mount i can gain an extra 25mm
09:35 AM JT-Shop: sounds like a mission to get as much travel as possible
09:46 AM perry_j1987: ya
09:46 AM perry_j1987: gang tooling
09:46 AM perry_j1987: i need 6 tools for my most complex part
09:46 AM perry_j1987: but i would also like to fit a cross drill as well to eliminate a 2nd op
09:48 AM perry_j1987: i think i need to order some alum plate to make a sub plate for the new lathe im almost sure i dont have any scraps big enough
09:49 AM perry_j1987: the idea is to have perm bolted subplate
09:49 AM perry_j1987: and then i'll make blocks on the mill that have the same locating pin holes and bolt downs
09:49 AM perry_j1987: then use the boring head in the lathe to make 16mm bores for tool holders on the spindle centerline
09:52 AM perry_j1987: just did some cad math looks like i can hold the 6 main tools i need in 115mm
09:52 AM perry_j1987: so there's room for a cross drill to have a bit of travel as well
09:52 AM perry_j1987: i should be good to go!
10:03 AM JT-Cave: got a photo of that rig
10:08 AM JT-Cave: you using mic6 plate?
10:11 AM perry_j1987: its a techno-isel 9x20 lathe
10:11 AM perry_j1987: dont think i need mic6 for the subplate
10:11 AM perry_j1987: all tool holders will be made on-machine
10:11 AM perry_j1987: so they will go back on well enough
10:17 AM perry_j1987: it will be nice. can leave tools in the blocks and swap blocks of tools for diff jobs
10:17 AM perry_j1987: just touch off and go
10:18 AM * JT-Cave heads to work
10:54 AM roguish[m]: JT-Cave: thought you you're retired...................................................................giggle, giggle.....
12:14 PM perry_j1987: what do you guys think about this machine https://www.cncmasters.com/max-cnc-mill/
12:35 PM ZincBoy[CAON][m]: Looks like one of the smaller tormach machines. I don't like that the Z axis uses the quill and not the column. Kind of limited for any real CNC operations.
12:37 PM ZincBoy[CAON][m]: The accuracy spec is highly optimistic based on the frame they are using. Unless they are re-scraping these themselves or have a magical supplier for the base machine, it will be hard pressed to maintain 0.01" across the travel.
12:38 PM ZincBoy[CAON][m]: Spindle RPM is a max of 4500rpm. I would like to see at least 6000 on a small machine like this. The frame is not rigid enough to use anything other than small cutters and those need RPM.
12:42 PM perry_j1987: aye
12:43 PM mrec: finally I wired up my dbls09 with linuxcnc - works very well
12:46 PM skunkworks: https://www.youtube.com/watch?v=sUz5ZZyf2LU
12:46 PM unterhaus_: what footwear do people wear in their machine shop? Something better than crocs
12:47 PM Tom_L: steel toed crocks of course
12:48 PM unterhaus_: I feel like chips get in them too easily
12:48 PM mrec: https://youtu.be/1GuDnaR2DBk?t=308
12:48 PM unterhaus_: although my machine shop crock experience is with the ones that have holes all over
12:48 PM mrec: In Pakistan they wear safety slippers
12:49 PM unterhaus_: O
12:49 PM unterhaus_: I'm surprised he had sandals on at all
12:49 PM mrec: look further
12:49 PM mrec: the other guy is welding on the floor a few cm away from his feet (again safety slippers)
12:50 PM unterhaus_: I have seen barefoot Indians doing casting
12:50 PM unterhaus_: not to mention the safety video where everyone was wearing a long scarf
12:50 PM ZincBoy[CAON][m]: I used to wear slippers in the shop but then I had a chunk of slag land on my foot when stick welding. I now wear slip on steel toed boots 🙂
12:52 PM unterhaus_: I was taking apart a brazed joint and had some filler drop on my sneakers. Fortunately I was wearing wool socks and it solidified before it got to my foot
12:54 PM unterhaus_: slip on steel toed boots might be good. Which ones do you have?
12:57 PM ZincBoy[CAON][m]: https://www.marks.com/en/terra-mens-murphy-6-inch-composite-toe-composite-plate-slip-on-work-boots-color-black-339306.html
12:58 PM ZincBoy[CAON][m]: They work great and the top of the boot is tight enough that weld spatter doesn't make it in. The lack of laces is also good as I have melted/burned more than a few.
01:05 PM unterhaus_: do you do machining in them? I'm wondering about chips getting stuck in the soles
01:10 PM ZincBoy[CAON][m]: Yes, I don't have those exact boots, those were just the first ones I found that were similar. Chips do get stuck but it is not really a problem.
01:13 PM Tom_L: just thicken the calluses on your feet
01:13 PM mrec: skunkworks: the emco thing is mostly aluminum no?
01:14 PM mrec: I was no fan of my emco compact 5 (no CNC) especially the plastic gib was rubbish
01:14 PM Deejay: cya
01:15 PM Tom_L: buy
01:17 PM perry_j1987: mrec did you have the turret
01:17 PM mrec: no I only had the manual lathe
01:17 PM mrec: it's still in Austria idling in the basement of my father
01:17 PM mrec: the chinese one feels better
01:20 PM perry_j1987: i got cad files for emco compact 5 somewhere
01:20 PM perry_j1987: has plans for the turret too
01:20 PM perry_j1987: would be kinda fun to build one i never see them on ebay
01:24 PM skunkworks: mrec: cast iron
01:28 PM mrec: yesterday I have installed 3 drills on my compound today I cut the first parts with it.. no more using the tailstock for drilling holes into stainles steel
01:28 PM perry_j1987: nice
01:32 PM skunkworks: mrec: the z axis ball screw nut is mounted in plastic too...
01:32 PM mrec: I wonder how the turret works for the E5C CNC
01:33 PM mrec: just a worm gear?
01:34 PM mrec: https://snipboard.io/eRPFox.jpg
01:34 PM mrec: ah
02:00 PM ZincBoy[CAON][m]: Generally a turret will have a hirth coupling with cylinder to lock it together. Just a worm gear would only be good for the lightest of duties.
02:08 PM perry_j1987: all pawls on the small turrets i see
02:08 PM perry_j1987: including the emco one
02:08 PM perry_j1987: wormdrive just indexes it then it locks on a spring loaded pawl
02:08 PM CaptHindsight[m]: skunkworks: I'm running closed loop steppers off of LPT
02:10 PM skunkworks: CaptHindsight[m]: closing the loop with linuxcnc?
02:10 PM CaptHindsight[m]: yes
02:10 PM skunkworks: cool!
02:11 PM skunkworks: I did it a long time ago - before mesa was a thing (emc2 just came out)
02:12 PM CaptHindsight[m]: each encoder count is only 50um at 8KHz
02:12 PM skunkworks: This is more of a - yes the printer port is still viable if you want to get into cnc cheap
02:12 PM CaptHindsight[m]: more than enough res for the application
02:13 PM CaptHindsight[m]: I'm trying to save Mesa cards for applications that require them
02:13 PM skunkworks: sure - In this situation - I have not changed any of the gearing - so the input scale is huge - 50800 per inch
02:14 PM skunkworks: so I am limited to about 35ipm with some headroom.
02:14 PM perry_j1987: be kinda cool to see something like a 7i96 with a pi compute module slot on it
02:14 PM skunkworks: but for that little lathe - more than fast enough
02:14 PM skunkworks: the one at the shop running mesa hardware - 200ipm no issue
02:15 PM skunkworks: scary fast
02:15 PM CaptHindsight[m]: 15in/sec here
02:15 PM CaptHindsight[m]: yeah
02:16 PM CaptHindsight[m]: I'm moving parts pretty slow except for one quick jerk of about an inch
02:16 PM CaptHindsight[m]: I could not find a hal example file
02:17 PM CaptHindsight[m]: except for the etch (etch-a-sketch)
02:17 PM skunkworks: I hacked together a file.. took about an hour... ;)
02:17 PM skunkworks: lots of copy and pasting
02:18 PM CaptHindsight[m]: same here
02:19 PM CaptHindsight[m]: https://forum.linuxcnc.org/media/kunena/attachments/1324/glassf-01Aug2022-1122.png
02:19 PM CaptHindsight[m]: the board used for this
02:20 PM CaptHindsight[m]: it only has one PCIe slot so I got https://forum.linuxcnc.org/38-general-linuxcnc-questions/46705-vantec-2-port-parallel-pcie-card-ugt-pce20pl
02:21 PM CaptHindsight[m]: skunkworks: whicj LPT card are you using?
02:23 PM CaptHindsight[m]: when I get some time I'm going to see about getting those <$10 PCIe LPT cards with wch382 working with LCNC
02:24 PM skunkworks: I don't know - I can look.. I have 2 different ones - but they both are 3.3v
02:24 PM skunkworks: compared to the pci couple I have that are 5v
02:25 PM skunkworks: all so far are recognized by linux so I can just just use port 0
02:25 PM CaptHindsight[m]: just curious to see which still work
02:26 PM CaptHindsight[m]: heh, I got used to just manually editing the hal based on lspci
02:27 PM skunkworks: I just found out recently you could use the linux port.. (0,1,2)
02:28 PM skunkworks: I though 'that must be a new feature..' it was added 10 years ogo
02:31 PM skunkworks: I know jon e is having problems with epp mode.. but i don't need that for raw i/o
02:32 PM CaptHindsight[m]: we are finding that a LPT system can run with a base thread as low as 20uS IF you don't run a browser or play videos
02:33 PM CaptHindsight[m]: a 6.x preempt_rt kernel on Ryzen only scores ~2uS for base thread jitter
02:34 PM * CaptHindsight[m] uploaded an image: (33KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/kYzBNXLBGbmcSQRMUhxnoqyn/ntu-20Aug2022-22.png >
02:37 PM skunkworks: I am running 22us base thread..
02:38 PM * CaptHindsight[m] uploaded an image: (38KiB) < https://libera.ems.host/_matrix/media/r0/download/matrix.org/coYrLYAPhoYrqktwPosukBFI/ntu-20Aug2022-34724.png >
02:38 PM skunkworks: the 8300 hp I use has a jitter of <10us..
02:38 PM skunkworks: 3rd gen i5
02:39 PM CaptHindsight[m]: skunkworks: which CPU are you using? and preemt_rt or RTAI?
02:39 PM CaptHindsight[m]: ah
02:39 PM skunkworks: preempt-rt
02:39 PM CaptHindsight[m]: great!
02:41 PM skunkworks: my workstation is a 5700g it is amazing
02:42 PM skunkworks: Actually got me back into gaming a little. (just a little)
02:43 PM CaptHindsight[m]: I am on a Ryzen3 2200G right now
02:45 PM CaptHindsight[m]: https://www.amazon.com/HP-8300-Elite-Computer-Quad-Core/dp/B01CV9G1BO $93
02:46 PM skunkworks: Yes - we still use them at work here.. they are really decent machines for the price
02:46 PM ZincBoy[CAON][m]: I am running the HP 8300 for my cnc machines right now. Works great and is super cheap.
02:47 PM skunkworks: I bought a few hundred of them from a university auction a few years ago..
02:47 PM CaptHindsight[m]: I can only rarely use a used system for customers
02:47 PM skunkworks: CaptHindsight[m]: sure.. understood.
02:47 PM skunkworks: how are new systems with latency?
02:47 PM CaptHindsight[m]: depends on the BIOS
02:48 PM CaptHindsight[m]: why i asked about yours since you never know
02:48 PM justache is now known as justache_
02:48 PM CaptHindsight[m]: the times I have taken a chance with HP it had a crippled BIOS and could not turn off power management
02:48 PM justache_ is now known as justache
02:48 PM CaptHindsight[m]: so best times were like 300,000uS
02:49 PM CaptHindsight[m]: still have it
02:49 PM skunkworks: oof
02:49 PM XXCoder: capt vant flash newer, or older bios to fix that?
02:50 PM CaptHindsight[m]: XXCoder: no, HP sells those to corporate clients, they remove most features to keep support issues to a minumum
02:50 PM XXCoder: geez
02:50 PM CaptHindsight[m]: same for Dell
02:51 PM CaptHindsight[m]: so it's a gamble IF you can't return or test the system first
02:51 PM XXCoder: dude! youre getting a dell... in your trash
02:51 PM XXCoder: yeah
02:51 PM CaptHindsight[m]: everyone else seems to have better luck with used systems
02:52 PM XXCoder: I dont buy prebuilt systems
02:52 PM XXCoder: my old pc was used for linuxcnc before
02:53 PM CaptHindsight[m]: https://www.amazon.com/Asus-Celeron-Mini-ITX-Motherboard-C8HM70-I/dp/B00APL76WO I did buy a stack of these used for ~$20ea
02:53 PM CaptHindsight[m]: the only Intel I have used in over 20 years
02:55 PM skunkworks: most the machines at the shop are running older amd.. But most are servo thread only.
02:55 PM skunkworks: eh - maybe I take that back.. there are some small intel boards too
02:56 PM skunkworks: CaptHindsight[m]: I am pretty sure i have put the latest bios's on those hp's without any trouble
02:56 PM skunkworks: certainly turn a bunch of stuff off in the bios.
02:57 PM CaptHindsight[m]: skunkworks: displayport only for the monitor?
02:57 PM skunkworks: vga and display port.. (works for 2 monitors too)
02:58 PM CaptHindsight[m]: great
03:00 PM skunkworks: I think peter has a few 8300's too
03:05 PM skunkworks: in my experience - adding a video card doesn't help latency
03:06 PM skunkworks: (on the 8300's)
03:07 PM CaptHindsight[m]: it hasn't helped in over 12 years
03:07 PM CaptHindsight[m]: that applies to system from the early 00's
03:08 PM skunkworks: CaptHindsight[m]: do you know of a already made pwm to +/-10v? (I only see single ended ones)
03:11 PM CaptHindsight[m]: nope
03:14 PM CaptHindsight[m]: there are probably some opamp boards that can do the single to differential that you can attach to a PWM to 0-10V converter
03:15 PM CaptHindsight[m]: skunkworks: do you really need the +-10V?
03:17 PM CaptHindsight[m]: https://electronics.stackexchange.com/questions/500458/conversion-from-0v-3-3v-to-10v-10v?rq=1
03:18 PM CaptHindsight[m]: use an opamp eval board
03:18 PM skunkworks: sure - I have found a few circuits..
03:18 PM skunkworks: I want to make the emco fully printer port for grins.. I would like to us an amc drive to run the spindle but it take +/-10v..
03:21 PM CaptHindsight[m]: skunkworks: which AMC part number?
03:30 PM skunkworks: I would have to look
03:39 PM roscogamer[m]: Intel has good nucs
03:40 PM roscogamer[m]: I'm usind a i5 One and the latency test shows like 8000 oh ish
03:40 PM skunkworks: tempted to run the the 2 servos with
03:41 PM skunkworks: https://www.amazon.com/Qunqi-Controller-Module-Stepper-Arduino/dp/B014KMHSW6/ref=asc_df_B014KMHSW6/?tag=hyprod-20&linkCode=df0&hvadid=167139094796&hvpos=&hvnetw=g&hvrand=8128842854526497631&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9019284&hvtargid=pla-306436938191&psc=1
03:41 PM CaptHindsight[m]: https://www.automationdirect.com/adc/shopping/catalog/process_control_-a-_measurement/signal_conditioners/universal_input/scu-8400 universal in/out signal converter, but $230ea
03:42 PM CaptHindsight[m]: low budget
03:43 PM CaptHindsight[m]: if you really want to demo low budget LPT LCNC control
03:43 PM skunkworks: yes - showing how inexpensive you could get a real control
03:43 PM skunkworks: get-em when they are young.. ;)
03:44 PM CaptHindsight[m]: speaking of which are your kids near middle school by now?
03:45 PM skunkworks: This is Stella's last year in elementry
03:45 PM skunkworks: she just turn 10 last week
03:45 PM skunkworks: Sully is 7
03:46 PM Tom_L: wow time flies
03:46 PM CaptHindsight[m]: Wichita fest was 9 years ago
03:48 PM skunkworks: yikes
03:49 PM CaptHindsight[m]: skunkworks: how is the drought effecting your area?
03:49 PM skunkworks: umm... I don't think we really had one.. Atleast in the imidiate area..
03:49 PM CaptHindsight[m]: all the ponds around here are just mud or dirt patches now
03:50 PM skunkworks: we just had 2 inches of rain a few days ago
03:50 PM Tom_L: i'm of the opinion it would be easier to load bookworm linuxcnc & friends and save the img file
03:52 PM CaptHindsight[m]: Tom_L: why bother with a whole rpi ISO
03:53 PM CaptHindsight[m]: just package a rt kernel and LCNC for arm64
03:53 PM skunkworks: bookworm? did I miss a release of debian? I think I am running bullseye on my laptop..
03:53 PM Tom_L: bookworm/sid is 12
03:53 PM skunkworks: sh
03:53 PM skunkworks: ah
03:53 PM Tom_L: trixie/sid is 13
03:53 PM CaptHindsight[m]: bookworm is after bullseye
03:53 PM JT-Shop: 13 will say bookworm/sid until it is in testing
03:54 PM Tom_L: neither are 'released' yet
03:54 PM Tom_L: https://wiki.debian.org/DebianReleases
03:54 PM JT-Shop: right
03:54 PM CaptHindsight[m]: what is the latest release for the Rpo4 from debian?
03:55 PM Tom_L: i've got buster running on mine
03:55 PM Tom_L: i could probably update it
03:56 PM Tom_L: had to catch up on some things today before i can 'play' with those iso
03:58 PM CaptHindsight[m]: why can't the Rpi4 or better ARM board install go: Install latest Debian, use apt for LCNC and rt kernel?
03:58 PM Tom_L: CaptHindsight[m], the build started out for i386 amd64
03:58 PM Tom_L: he posted the links for arm so i tried to build them
03:59 PM Tom_L: you would have to get it to boot from USB for one
03:59 PM CaptHindsight[m]: what comes pre-installed on the Rpi4?
04:00 PM Tom_L: rasbian or such
04:00 PM CaptHindsight[m]: that you can't get anyway so why bother?
04:00 PM XXCoder: theres great rpi setup program anyway
04:00 PM Tom_L: i forget how i got to buster on it
04:00 PM XXCoder: you choose from bunch of packages ready to flash into sdcard for rpi4
04:00 PM XXCoder: tom you solved that fat thing yet?
04:01 PM Tom_L: not a fat thing
04:01 PM Tom_L: more a bootloader thing
04:01 PM XXCoder: ahh solved that>
04:01 PM Tom_L: no
04:01 PM CaptHindsight[m]: the only Rpi4 Linux that worked well for me was a Gentoo arm64 image
04:01 PM XXCoder: did you see what pere said about it?
04:01 PM CaptHindsight[m]: everything worked with no cruft
04:02 PM XXCoder: I used few packages, all worked fine for me. standard package and octipi
04:02 PM CaptHindsight[m]: I don't know why rasbian can't do similar
04:02 PM Tom_L: https://raspi.debian.net/tested-images/
04:02 PM Tom_L: i tried one of those
04:03 PM CaptHindsight[m]: 4k monitor also just worked

04:21 PM Tom_dev: https://github.com/emojifreak/debian-rpi-image-script
04:22 PM Tom_dev: to create your own image file or install straight to the SD card, from another running GNU/Linux machine.
04:23 PM Tom_dev: read 'Rolling your own....' from the first link
04:24 PM Tom_L: that sounds too easy
04:25 PM CaptHindsight[m]: you can add some pushups in there if it makes you feel better
04:25 PM Tom_dev: https://gist.github.com/emojifreak/180b335cd58edd9a64fc42b85f735c6d
04:25 PM Tom_L: so build one on a fresh ssd then run the script
04:28 PM CaptHindsight[m]: if you have a working Rpi4 system now you can also just tar up the filesystem and then dd it onto an SD-card
04:28 PM Tom_L: right
04:28 PM Tom_L: you would want generic user etc though

05:18 PM XXCoder: looks like nice guide. saved for future
05:22 PM * JT-Shop is making an inside window box with wood hinges to hide the tomatoes from the cat
05:26 PM Tom_L: what about the possums or racoons?
05:29 PM Tom_L: how do you check your rpi4 firmware version?
05:31 PM XXCoder: window box is good if you get tomato monsters too
05:31 PM XXCoder: keep em inside ;)
05:32 PM XXCoder: "attack of the killer tomatoes" movie. lol
05:32 PM JT-Shop: I deal with the possums and coons a bit differently
05:32 PM JT-Shop: check and see if there is /etc/debian_version
05:32 PM Tom_L: got a couple friends to help? Mr Smith and Mr Wessson?
05:32 PM Tom_L: it is 10.xx
05:33 PM JT-Shop: haveaheart and heritage arms
05:33 PM JT-Shop: my friends are Mr. Dan and Mr. Wesson
05:34 PM JT-Shop: I also have a good friend named Kimber
05:34 PM Tom_L: or a good cannon shot over the bow
05:35 PM JT-Shop: or a ballista bolt
05:39 PM Tom_L: have you ever tried updating rpi4 eeprom firmware?
05:39 PM JT-Shop: no
05:40 PM Tom_L: sudo rpi-eeprom-update tells you if there is one
05:43 PM JT-Shop: on the dev mailing list there is a guy that has made 2.8.3 work with a 7i96S so testing that in the am
05:43 PM Tom_L: what os?
05:43 PM JT-Shop: debian 10
05:44 PM Tom_L: i wonder if there's a way to tell the hostmot2 version
05:44 PM JT-Shop: I've wondered that as well
05:45 PM JT-Shop: other than unknown board lol
05:47 PM Tom_L: it might be something good to add since there are different fpga now
05:52 PM JT-Shop: I've not found a way to tell what date the linuxcnc build is from
05:55 PM XXCoder: isnt there info in about
05:56 PM JT-Shop: hostmot2 is a hal component
05:56 PM JT-Shop: there is no info
05:57 PM XXCoder: should be possible to add date of compile to it
05:58 PM JT-Shop: it's not a compile date but the date of the repo
05:58 PM JT-Shop: The 7i96S requires LinuxCNC Uspace 2.9 Febuary 24, 2022 or newer!
05:59 PM XXCoder: hmm maybe need some changes to be more clear
06:03 PM Tom_L: that was easy
06:04 PM Tom_L: sudo rpi-eeprom-update -a
06:04 PM Tom_L: and reboot
06:04 PM XXCoder: I probably need to do that also. my rpi4 isnt exactly, it predated scalp
06:05 PM XXCoder: *exactly new
06:06 PM Tom_L: there are other firmware available
06:07 PM JT-Shop: WOW we are making progress on making the 7i96S work on 2.8!
06:08 PM Tom_L: awesome... i'm glad someone is making progress :)
06:08 PM JT-Shop: Andy is helping a lot
06:09 PM Tom_L: did hostmot2 get pulled to 2.8?
06:09 PM Tom_L: the new one
06:09 PM JT-Shop: not yet I have to test a branch to see if the 7i96S works in the am
06:09 PM JT-Shop: no new priority for tomorrow
06:10 PM Tom_L: so what got put on the shelf?
06:10 PM Tom_L: :)
06:10 PM CaptHindsight[m]: JT-Shop: is there any way to add configuring LPT cards with MesaCT?
06:10 PM JT-Shop: testing the other branch
06:10 PM JT-Shop: of course anything needed can be added to mesact
06:14 PM JT-Shop: like the one bari mentioned on the forum?
06:16 PM JT-Shop: chow time here
06:23 PM CaptHindsight[m]: Stepconf doesn't know what to do with some LPT cards and no longer lets you manually enter in the register addresses
06:23 PM CaptHindsight[m]: you have to manually edit your ini and hal
06:24 PM CaptHindsight[m]: you also don't know which LPR card is which if it does find them
06:24 PM CaptHindsight[m]: your only choices is 0, 1, 2 or .....
06:24 PM CaptHindsight[m]: and it doesn't tell you which LPT card is 0, 1, 2 or ?
06:25 PM XXCoder: strange
06:25 PM XXCoder: why was that removed? I had to make manual entry on mine
06:25 PM CaptHindsight[m]: no clue
06:27 PM CaptHindsight[m]: maybe they thought this way is easier for noobs?
06:31 PM XXCoder: dunno

11:20 PM mrec: checking limits is really messed up in linuxcnc...
11:33 PM mrec: angry.... this limit checking can totally lock up linuxcnc and it's always about a 0.00000...x violation
