Wow, those are some pretty hefty files you're working with. 
Thanks for sharing more with us.

I have another question. I select the option to turn on the spindle. Output 27 is the option available, but it doesn't output 24V to turn on the relay and start the engine. The other available outputs (numbers 12, 13, 14, 29, 30, 31) always output 5V. Therefore, I wouldn't be able to connect a relay for the refrigeration pump and other control outputs. I've already changed the input and output functions, but the voltage remains the same.

At work I use a 5axis large format machine, ive had over 100mb files before cutting for ~25 hours. 
It has a tool changer but rarely used since it gets full of crud- crappy gantry design with very little dust extraction.
Much fun!

Hi everyone,I owe you an apology for the month of silence. The reason is that I've been completely focused on a hardware project called Proton – a CNC motion controller I'm developing alongside NativeCAM. I've put up a page atwith some info, but honestly, that project has been consuming all my focus and time, and I let this thread slip.Now that the hardware side is stable, I'm back and catching up on everything. I've read all three pages of this thread, and I've just replied to each of you individually (Surmetall, COFHAL, Doug Crews, and others).Over the next week, I'll push fixes to the GitHub repo (especially the blank GladeVCP tab and the OWord path documentation) and prepare the lathe test package.Thank you for your patience – NativeCAM is still very much alive.— Axemas

@Doug Crews – thanks for the report. The blank tab is a known issue with the -4 package on Trixie. GTK deprecation warnings break the embedded GladeVCP renderer.

Workaround: run nativecam standalone once, close it, then launch LinuxCNC – the tab should appear.

Also check your INI: NCAM_DIR should point to /usr/share/linuxcnc/aux_gladevcp/NativeCAM if the default doesn't work.

I'm fixing this properly in the next release (-5 or -6) within a few days.

Run one of the included configs for parallel port, if those run you are OK.

@COFHAL – you asked about the ~/nativecam directory and OWord macros. Here's what's going on:

NativeCAM creates and uses ~/nativecam as its working directory for temporary files, tool tables, and post-processor configs.

The SUBROUTINE_PATH in your LinuxCNC INI file must include the path to the OWord subroutines that NativeCAM generates. Without that, LinuxCNC won't find the macros.

If Axis shows no errors but QTDragon fails with "can't find macros or OWord," it's almost certainly a path issue.

Quick fix: add something like this to your INI file:

text
[RS274NGC]
SUBROUTINE_PATH = ~/nativecam:/usr/share/linuxcnc/ncfiles
Restart LinuxCNC and try again. If it still doesn't work, paste your full INI file here and I'll debug it with you.

@Surmetall – thank you for the kind words and for the continued excitement about the lathe features, especially the polyline workflow alongside G71/G72/G73. That preview video took a lot of work, and it means a lot that it sparked anticipation.

Since my last update, I've been testing the polyline path generation on real G-code scenarios. No major blockers – mostly fine-tuning the toolpath logic and cleaning up the UI response for lathe operations. I'm planning to push a test package soon.

And yes, I'd absolutely love for you to test it on a real machine. Your offer to provide feedback, screenshots, and G-code examples is gold. I'll reach out to you directly when I have something ready for real-world testing.

Hey @giunta.gio — apologies for the late reply, I completely missed your question back in May.The main hardware specs and overview are now live at cncproton.com/ We're currently finalizing the full technical documentation package. Over the next couple of weeks, the site will be updated with:

• Detailed wiring diagrams and complete pinout tables
• Example HAL configuration files for LinuxCNC
• More photos of the assembled modules and various configuration options

If you have any specific questions about your machine or particular hardware features, feel free to ask here or reach out through the contact form on the site — I'm happy to go into detail.Axemas

Hello Tommy:

The installation worked and I am able to launch the latency_histogram and 3D gears tests.

However do you know if there is a script or I am still missing steps in compiling the 
rtai_lxrt.ko, rtai_fifo.ko, rtai_sem.ko,rtai_sem.ko, rtai_tbx.ko, rtai_bits.ko and rtai_mq.ko kernel modules.

I check the /usr/realtime-5.4.258-rtai-amd64/modules and I only see a shorter list of compiled RTAI specific kernel modules

Always the 'joint 1 on limit switch error' or 'joint 0 on limit switch error'.
Mostly at pierce now, but has slowly been creeping in and would do it halfway through a cut. same error.

Spumco, great work. If you have to manually start the service each time. sounds like you overlooked the udev rules in the first post, Sorry about the formatting errors but its an awful post to edit

sudo geany /etc/udev/rules.d/99-ethercat.rules
and the following code block.
 

Rod - I hadn't actually gotten to that section of the installation yet.  The first 'ethercat slaves' check is before the 99-ethercat.rules line.

I just stopped when I got the errors starting ethercat service for the first time.  Bulldozing ahead past errors has not served me well in the past, despite my habitual attempts.
 

OK, hold the EMI filter thought for now. When I had EMI issues, fitting one solved it.
Choose from here locally, but there are other IEC connectors with mains switch and fuse built in
www.jaycar.com.au/components-electromech...-emf-products/c/2GLC

But in your case what is odd is that its been trouble free for so long. When you say error, is it always a limit switch error or could it be the arcOK is failing?

 

Still using the hypertherm XP45. it's been on it the entire time.

no EMI filter yet.

Hello,
I'm wanting to set up an environment for learning cnc concepts with Linuxcnc
  e.g. Machine PC plus development/simulation PC
Goals are to
  understand cnc systems
  experiment with cnc systems
  build a capable hobby machine
Skills
  Familiar with Linux (Gentoo)
  Basic coding skills. Bash, Python, read, write, loops and if statements

So far I have a working pen plotter built, and based around Openbuilds Acro XYYZ using Fluidnc ESP32 controller.
Linuxcnc installed on old PC (parallel port), in my garage workshop with Aliexpress BOB arriving soon. Plan is to move to Linuxcnc.
Main PC in my house. No network connection yet

Question
  What is good set up?
    Simulation setup on main PC to sort out configurations... transfer to machine PC? Is this workable.
    SSH into Linuxcnc box and used command line tools to work in Linuxcnc?
    VNC or something similar?


Phil
