if you want to try i added dedicated hal pin to the spindle encoder index, you can connect it to any input pin, and you can define in the config.h and also set the active level of the signal to active low or active high.

If the original manufacturer thought that is was important enough not to require homing to go to the trouble of fitting potentimeters I would be inclined to follow their lead.
I don't think it's a difficult thing to integrate.

I see you have two slaves with idx="0", that won't work.
List the indexes with "ethercat slaves"

There is another debug option or possibility. The output of "sudo dmesg" show a lot, at the end it may have info that can show the error.
Especially info messages from ethercat master and lcec goes there.

Good morning, I want to update my Qtplasma and would like to know if there is a step-by-step guide for doing so. Thank you.

You`re right. When I realized that it is a special customized Version I started everything all over again to go with the simplest version. I did what you proposed and compiled the cia402_homecomp. Than I mixed my working Beckhoff starting point files with the ones from dbraun. Unfortunately it still crashes:

wopass: load_the_modules cmd=<orig_loadrt lcec>
waitpid failed /usr/bin/rtapi_app lcec
/usr/bin/rtapi_app exited without becoming ready
insmod for lcec failed, returned -1

Do you have any Idea what to try next?

Please disregard my last question!

I was overthinking this and glazed over the simple method that was right before my eyes.

As my question
Usually, no matter what system it is, the planner starts with speed 0 in planning.
However, in some cases, in order to improve work efficiency, if the motor and drive allow, I can set the machine to start planning at a speed of 50 (we think the servo can run up)
So how do I need to set it up? Does linuxcnc support this setting?

Yes it is missing.
Maybe you already have fixed it by now. It's not a standard component so you need to "halcompile --compile cia402_homecomp.comp" to put the .so file in you config directory.
It's daring to try to get the servo working using a custom setup, I wouldn't do it. I would start with the simplest config possible from dbraun1981 and when that works I would build on with other functions.
But i understand this is part of a complete working setup, so you need to find the cia402_homecomp, compile it and hope for the best.

Thank you kindly PCW for your reply.

This might be a very stupid question, but how do I implement the link you provided into MesaCT?

Do Just download the last hostmot2.c and mesaflash.c files and swap them into the mesa flash-master folder?

Excuse my ignorance!
