I just edited the automatically generated .ini and .hal files as needed or commented out lines until LinuxCNC worked. The limit switches, etc. are also not wired yet; I just want to test the old amplifiers once. So, nothing fancy. Maybe I removed too much there or haven't adjusted it yet...?

The hal file is almost entirely commented out so will not do much.

I would start again (with the original files) and if you get a LinuxCNC startup error, post it here

I've now loaded the standard 7i97t ini and hal files, and after a few minor adjustments, LinuxCNC is working (name, IP). In the hal file, I've only commented out the encoders and end positions for now, as they aren't connected yet. Is it even correct that the analog outputs are displayed as PWM? The only difference is that the value is set to higher values ​​(e.g., 17) when using the LinuxCNC interface.

Yes, in the hal file, the analog outputs are all controlled by PWM values.

The actual PWM value shoudl be set by the output of a PID component that
in turn reacts to the difference in the encoder position to LinuxCNCs
commanded position.

Yes, the value comes from the PID. My power amplifier is a -10/+10V. Is the value a voltage value? If the value is, for example, 17, I measure at the Mesa only 0.35V.
