VMC related HAL questions.

You have

Code:

loadrt orient addf orient.0 servo-thread #loadrt mux2 -- This has already been loaded in the sim_vmc.hal addf mux2.0 servo-thread # chooses which pid output goes to the spindle speed control

You need to un-comment the loadrt mux2, as I don't think you have that loaded elsewhere.

Code:

#for a real spindle run by a VFD loadrt abs addf abs.0.servo-thread net spindle-cmd mux2.0.out abs.0.in net spindle-cmd-abs hm2_5i25.0.7i77.0.1.analogout5 #net spindle-fwd abs.0.is-positive parport.0.pin-NN-out #net spindle-rev abs.0.is-negative parport.0.pin-NN-out

This needs to be To send the bipolar speed command to the analogout.

Like this?

No...

Replace the entire section I quoted with the single replacement line.

Oh, when reading your message again it seems quite obvious :blush:

Tried it in the machine but I see no change in behavior. I did not get any errors at startup.
Tried a M3 S100 but It doesn't compensate at all? Am I missing something here?

M33.1 Does not do anything ether.

EDIT: Oh wait, I´m stupid.. Did get an error though

EDIT2:

You will need to tune the PID values in the INI file.
Your ini file has [SPINDLE_9] Whereas the HAL is using [SPINDLE]
These need to match.

The fact that LinuxCNC starts at all with that misconfiguration makes me wonder if it is finding the right spindle.hal file.

Odd. Was the spindle turning? Has G33.1 worked before? The HAL connections seem correct.

Ignore what I was wrote earlier. I replaced the wrong config folder so there was literally no change to before.

Did it right after that and then I got that error message and Linuxcnc does not start.
