As someone who has built many CNC machines (some on my channel) and as someone starting to program and use the Raspberry Pi... I am SERIOUSLY IMPRESSED with what you have accomplished! Excellent video and I will be sure to share!

Thank you Chris. I came across the video and it was well put together giving me a great start. I got my pi ready for some testing. Hopefully it will work for me as a fumble along.

Wow, great build. I'm working on almost the same project.....!!! Thanks for posting your HAL file, that's always painful to construct.

Amazing! The first time I heard you ask “how hard can it be?”, I thought that nature would be readying a can of whoop-arse, but then I heard you ask it a second time, tempting fate. Yet you carried it off extremely elegantly. I take my hat off to you sir!

Super work.! I especially like very much that you open source your findings. Thx Form a long time lcnc user.

Excellent work and thanks for sharing - really useful stuff. I expected you to sound a bit happier at the end having achieved all that though! 😉

Thank you for a great video(stumbled upon it accidentally-glad I did). I am looking to do something similar and your video is just what I was looking for. Great job. I am confident I will have questions, so I will be reaching out to you.

UI fix is hard but use "glade-3" (not just glade). My screen is vertical. Anyways, you deserve an upvote. Useful stuff! Thanks for taking time posting this!

Very helpful. In particular the video actually has a diagram showing the parts connected, and an explanation of what they are for. To be honest, explaining the function of a breakout board would have been even better, but still this is much better than the usual how-tos. As a former software architect, I'm struck at how uncommon it is to get an explanation of the overall architecture of a system (software or hardware). I'm probably going to build your two boards, as you seem to be out of stock.

Very good👍🏻 i think about to use your with the open cnc shield 👍🏻

Fantastic effort.

Many, many huge thanks for lighting the way in the wilderness. 👃😁

Thanks , nice work

Thank you so much!

Amazing!!!!!!!!

I actually went with an RPi4 with the Mesa 7C81. It works like a champ. Documentation sucked at the time, but maybe it's getting better now that this stuff is in the stable release of LinuxCNC? I just wish there was more friendly tutorials for the HDL for LinuxCNC. Looking at the manpages as a newbie is a nightmare in my experience, but there seems to be so much stuff in there that has a lot of potential.

Do you think RB Pi4 with Linuxcnc will work with Mesa card 7i76E (communication RB Pi 7i76E is via ethernet cable)?

I first would like to say I love this project. Second when i am trying to use the linuxcnc-2.8.0-Pi4 zip i keep on a Pi4B 2GB i keep getting a startup error: 0.788381 kvm [1]: Error, CPU 0 not supported! and then then when it finally loads into the desktop the mouse and keyboard do not work. Any suggestions? Thanks

Hi Chris, thanks for the great video and PCB designs seems like a nice design. I would like to give this a try as well also like the idea with the small touch screen. Did you publish the Gmoccapy screen resolution changes somewhere (a linuxcnc fork maybe)?

Did you run a latency test? If yes what is the outcome?

I have a Shapeoko 4 axis machine with stepper motors, y axis uses 2 together. The machine has its own stepper controller. This can interface with a Raspberry Pi but at the moment only works with Carbide Motion software (via a USB cable and uses GRBL commands), this software doesn't support the use of the Pi GPIO. I want to run the machine via an external input and also want to switch on 1 or 2 outputs using M codes. I will add a relay interface module to switch the outputs. Will Linux CNC run this machine from the Pi?

Nice job Chris! Do you have any concerns on the longevity of the micro SD card in the RPi?

Usa a mesma versão do Linuxcnc para desktop ou é uma versão específica?

Just for reference, but there is actually a mesa card specifically designed to work with the rpi, just for anyone wondering.

Good

Hi @Chritoph. One question: how feasible and easy do you think would be to adapt this set up to a 4-axis CNC? any Docs you can point out? Thanks.

Thanks Chris! I was wondering if you had the stl file for the raspberry pi and bob mount you drew?

Hello, Thanks for the great video! What is the advantage of using your interface + Breakout boards over the raspberry protoneer board? Thanks

Nice music

I wander, what's the latency and jitter? As the first error message you got after starting LinuxCNC was that of too much latency. I'm really interested as to how did you solve that problem.

Thank you for the excellent video. Would it be possible to get a copy of your .stepconf file? Thanks in advance.

OPEN SOURCE = LIFE THANKS@

LPT RPI board schematic? "Connector_dsub: DSUB25_Female" at 8:21 min.

Hello Chris . Can you plz tell me how to set tool changing in mach3 bob need help Thanks

great project kudos. I wonder if it is possible and how to turn the function on the limit switches? if the switch is in position 0 in halshow it shows 1 and if I press it it shows 0

Great video, but what is the purpose of the touchscreen???

Not sure if you would know this or not but I have a small sainsmart cnc clone that runs GRBL, is it possible to use LinuxCNC on a raspberry pi to control it through the mini USB port in the same way I use octoprint on a Ubuntu PC to control my two 3d printers?

They have a mesa raspberrypi hat now for things like this

I have problem with Touch Screen not working, spended couple hours trying to fix it seems like i cant find solution, did u have problem with that? Tnx

The level shifter board is in your github but the PI-LCNC is not. Are you planning on making that available too?

Can the same thing be done with LattaPanda Alpha

You really don’t need Raspberry pi specific Mesa hardware. Using the iso you linked, and a 7i96 card it’s basically plug and play. The gpio pins are limited in their ability to generate pulses of high frequency so you’ll just be limited on your feed rates (as I understand it).

Did you consider buying USB to LTP cable?

thank you chris. i have a question. I want to make my own cnc. can i use the hardwares you used in my software? i dont want to use such as linuxcnc or grbl converter? can i send the gcodes to machine line by line using this hardware? (using socket module or pyserial)

Sorry to bother you Chris. Great video, I got the shifter and the LCNC but am having an issue getting it to work together. I used your pi image, when I choose a configuration and setup the proper pinouts and everything the steppers do not move. I feel like an idiot lol. Do you have any ideas what I could be doing wrong?

Kannst du sagen, was die maximale Frequenz ist, die du damit ausgeben kannst? Ich würde gerne wissen, ob das auch für meine Maschine ausreichend ist. English: What is the may. frequency you can drive? I want to check if it fits also for my machine.

Hi Chris, I am looking to control a self-build machine, I would like to know where we need to modify the pinout file for the motor (11:08) from the linux CNC. I just to add a few more degree of freedom 7 axis. Could you share your files?

hey nice job! I have had similar thoughts about my router. Its currently running linux on an old desktop machine but its super bulky and overkill for what it needs to do. How are you finding the performance of the pi?

please someone help me, but if there is any raspberry pi 4 lnux cnc os ready tell me about it

Are the lpt board (upper level shifter) is your product?whats about the schematic for this?

Hello Christ, I am a software engineering student at a college in the US. I have project due this semester that needs a PCB kit. Specifically, the PI LCNC board. What is the best way to contact you to order a kit?

how can I reflash the raspberry

Can you use linuxcnc on numvee controler

thx chris is a great job you did . mine project is les compicated . i just need one single x-axe to be controled with a stepper motor .Can i use the pins of the pi 4 use directly (one transistor inbetween for the 3.3 to 5v adustment) and use partli your hal file just to activate 2 pins for puls and direction like loadrt [EMCMOT]EMCMOT base_period_nsec=[EMCMOT]BASE_PERIOD servo_period_nsec=[EMCMOT]SERVO_PERIOD num_joints=[KINS]JOINTS loadrt charge_pump loadrt hal_pi_gpio dir=78855 exclude=32918520 loadrt stepgen step_type=0,0,0 # --- begin addf s addf hal_pi_gpio.read base-thread addf stepgen.make-pulses base-thread addf stepgen.capture-position servo-thread addf motion-command-handler servo-thread addf motion-controller servo-thread addf stepgen.update-freq servo-thread addf hal_pi_gpio.write base-thread # --- end addf s net xstep stepgen.0.step => hal_pi_gpio.pin-03-out net xdir stepgen.0.dir => hal_pi_gpio.pin-05-out

Raspberry with 2/4 or 8 GB?

Hey Gibt es das Video auch auf deutsch ?

Very cool project . How can I get in contact with you ?

can we run mach3 ?

The installation of Raspbery Pi OS with Linuxcnc 2.8.0 can be done more easily by downloading the full LinuxCNC image directly from here: linuxcnc.org/downloads/. if you want to try the 64-bit version, you can look here: forum.linuxcnc.org/9-installing-linuxcnc/39779-rpi4-raspbian-64-bit-linuxcnc?start=10#181585

Hi, I am trying to do something similar. Could you please give me your hall file?

hi Christoph I have send you email and also message in your shop but i haven't got any response ...

interesting but not understand anythink. i have raspberry pi zero,3 and 4 but newer not can add image in boards, i have one old mini computer whit sd card and in have emc2. but hardware not have ready. no have tube at frame can welding all. thailand have problematic build anythink, no found material no have help, not anythink. north europe u build 8 cnc machine wery easy all parts can buy local store or orden internet, thailand not can anythink.

so yeah, this seemed like a great idea... then I watched the video and realized that I am nowhere near smart enough. *Awkward face* why must i alwayd do things the hard way.

need use FPGA card, uh, super expensive ower 200$ linux cnc and old paraller printer port computer what can buy 20$ and linux cnc FREE need controller card cost 10$ and then drivers ewery stepper cost 40$/motor. lot cheapen than raspi. uh.

hi, can youz show the plan of wiring this all things together without 3v converter - i mean direktly to raspberry ? It would be epic!
