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

Installing LinuxCNC RTAI

Category: Installing LinuxCNC

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.

Test system setup

Category: General LinuxCNC Questions

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

What plasma cutter are you using these days?
Do you have an EMI filter on your mains inlet to the control box? Jaycar have them

Couldn't find any spots showing voltage.

Ran new earth wires everywhere, from the gantry, torch holder, x axis motor mount, y axis motor mounts, table, water table.

No change, still getting errors when the torch begins a pierce.

You could use the hal scale  component to subtract 50 from the commanded spindle speed,
something like:

loadrt scale
setp scale.0.gain 1
setp scale.0.offset -50
net spindle-vel-cmd-rpm => scale.0.in
net fixed-spindle-rpm scale.0.out  [HMOT](CARD0).pwmgen.00.value
addf scale.0 servo thread

sudo apt update and upgrade seems to have fixed whatever was wrong.

after reboot:

mill@debian:~$ sudo systemctl start ethercat.service
[sudo] password for mill: 
mill@debian:~$ ethercat slaves
0  0:0  INIT  E  AS715N_sAxis_V0.10
1  0:1  INIT  E  AS715N_sAxis_V0.10
2  0:2  INIT  E  AS715N_sAxis_V0.10
3  0:3  INIT  E  AS715N_sAxis_V0.10

I think I'm in business.

Thanks a ton for the assistance.

That seems to have worked, sort of.

I got the following errors while pasting the commands:
Warning: Spoiler!


fix-broken install and dkms autoinstall seemed to have worked (no errors)

dkms status | grep ethercat reported "installed"

systemctl status ethercat.service:
Warning: Spoiler!


But final commands got an error:
mill@debian:~$ sudo chmod 666 /dev/EtherCAT0
chmod: cannot access '/dev/EtherCAT0': No such file or directory
mill@debian:~$ ethercat slaves
Failed to obtain number of masters: Failed to open master device /dev/EtherCAT0: No such file or directory


I wonder if the "dev" folder is for a RIP install?

Ok, Now it's working... I found a post here with this:

# ---PWM Generator signals/setup---

setp [HMOT](CARD0).pwmgen.00.output-type 1
setp [HMOT](CARD0).pwmgen.00.scale [SPINDLE_0]OUTPUT_SCALE
net spindle-vel-cmd-rpm => [HMOT](CARD0).pwmgen.00.value
net spindle-enable => [HMOT](CARD0).pwmgen.00.enable

it's working... I only have some "scale" problems...

the actual speed capabilities goes from 50 to 4000RPM.

BUT wihth S50M3 it goes to 104rpm... 
to get it to 50rpm I need to send S1M3.

testing I'm getting:
S1M3 => 50rpm
S3450 => 4000rpm

How can I set this to be:  
S50 => 50RPM
S4000 => 4000RPM
?

Thanks.
