OK, i forgot what this was about, so yes, do continue testing and poking around.
Youtube will use graphic subsystem and that must use interrupts and other resources, causing spikes. Use integrated graphic, usually that works OK.

I wanted to see the stepper turn correctly, also to understand how ini and hal work if they are connected to each other. Honestly I would have liked to see the system turn with youtube active without errors.

I have a few observations:

no pulses are generated for reverse movement when the magazine turns in one direction the stepgen.2.position-cmd value changes by 400 then stepgen.2.position-fb and carousel.0.counts tend to this value. when the moment comes for reverse movement nothing changes in the three above parameters. despite the fact that the Dir pin changes there are no pulses - so for some reason the carousel component does not add pulses resulting from the set carousel reversing time. N .rev-pulse .
I do not know how the mechanism should work the instruction says carousel.N.rev-pulse float in
The duration in seconds for which a ratchet changer (Boxford, Emco) should pulse the reverse pin to lock the holder.
on logic so pulses in an indefinite number for a specified time possibly some mathematics could calculate that if someone wants the reversing to last 5 sec. and the pulse frequency is known, stepgen.2.position-cmd should be increased by the result of these calculations and the pulsation command should be issued.

sorry I was no clear What yo mention is the actual process What I stated is the future state if the process can be modified we trying to avoid using 2 materials or 2 gCode files or edit the Gcode file to change PD to 0

1. make piercing using another material config, for piercing only
2. ok
3. ok
4. start cutting with config for the material you are cutting.

What problem?
None of the above are problems, you can set homing pretty much as you like or need or see fit.

Yes that is for parallel port only.
I have to ask, why are you messing with these settings?
What are you trying to do?
What is working and what not?
For configuration you should have asked in the Remora topic, might get better help there.
