I've took additional measurements using the debug mode and terminal output. Attached is a video containing two following measurements.

In the first measurement, the feedrate value was constant throughout the probing. In the second measurement, the value was deliberately changed by feedrate potentiometer.



The terminal output shows that in the second measurement, the following lines were added:
[DEFAULT.QTVCP.QT_ACTION][DEBUG]  CALL_MDI Command: G91 (qt_action.py:182) 

The command M64 P4 at the beginning and M65 P4 at the end were added and are necessary for "turn on" and "turn off" of my probe.

Terminal output also in attachment:

Moved to "EtherCAT" section.

Do we have input shaping in Linux CNC as Klipper in 3d printers ??

No, not yet, nor am i aware of anyone working on it.

Oh, interesting.
So do I understand right - it should work when I find a PIC programmer that can program it? I guess that should be doable.
Is there a pinout for the programmer pins?

best regards & thanks for your support,
Alex

I talked with my contact and he said its possible (he even did it before).

Edit: I attached a G-Code sample from him, that was generated by one of his posts.

I have a new basic setup and I have motion working, and am expanding and fine-tuning from there.

I have a few questions
1. What is the best mode to use? csp? `setp cia402.0.csp-mode 1`
2. Where is the best place to do 'scaling'?  In Linux-CNC (hal & cia402) or in the EtherCAT driver/controller?
3. Where can I fiind documention for `ethercat-conf.xml`, I am using one based on github.com/dbraun1981/hal-cia402/blob/ma...le/ethercat-conf.xml, and want to understand the option and what else should be in there?  I want do add SDOs.

Thanks!!!!

Do we have input shaping in Linux CNC as Klipper in 3d printers ??

Thanks for your answer. Attached the result.Linuxcnc works with the changed value. But the GUI doesn't recognize the change.

I bought that same Hynade 80amp cutter in October '23 and have been running it ever since on my homemade linuxcnc/mesa table, no complaints at all.

I did some research on the torch and found the manuals from Tecmo are the source of the torch or are excellent copies.

I purchase torch consumables under their part numbers from ebay seller PlasmaDyn www.ebay.com/str/plasmadynplasmaweldingparts

Looking forward to this build.

I see. I'm not very familiar with editing post processors so I have no idea what's possible. I've made a sketch to give you an idea of how Tilted Work Plane (TWP) would work in the example part.

 

What we need is the offset from the current WCS (G54) to the new origin of the TWP. After that we can use regular 3axis gcode to mill the feature on the inclined plane.
Note that the g68.3 command accepts an optional 'R' word to change the direction of the new X axis.

this is the result:

Thanks, I will read through that thread to see if it will help, however that thread is for a closed loop drive and mine are open loop. The drives know they are open loop, but I am wondering if linuxcnc knows they are open loop. Where is that set in linuxcnc?

Sorry Chris.
Thank you.

Thanks I got 1 of 3 to work.
So now I know i need new ones.

So I will just order som pnp
And do without extra components.
Make it easy on the "next guy" comming to repair.

Here is what I put in my .Hal file for a standard MPG. This is for EC500 and the switch need to be set to STD MPG on the controller
