Oh yes LOUD and clear. Also tested M3/M4 manually, fixed speed setting in VFD control panel and spindle runs OK.

Can you show us the spindle-related bits of your HAL?

I don't see any sign of any connections to the hm2_5i25.0.7i76.0.0.spin* pins in that HAL file.

I think you need
net spindle-enable hm2_5i25.0.7i76.0.0.spinena
net spindle-vel-cmd-rpm-abs  hm2_5i25.0.7i76.0.0.spinout
net spindle-ccw  hm2_5i25.0.7i76.0.0.spindir

This is completely ignoring the closed-loop spindle PID that is included in your HAL file because using that will require connecting the feedback and tuning the [SPINDLE]PID terms in the INI file. And that sounds like a second-stage of the process.

Well works only with MDI M3 Sxxx or M4 Sxxx but only at one fixed speed. No go from main screen!

After pressing the spindle-clockwise button you then need to press the Spindle-+ button to increase the speed, are you doing that?

If it only ever runs at full speed then that probably mans that you need to
setp hm2_5i25.0.7i76.0.0.spinout-scalemax 5000

(Or something similar to suit your actual spindle max speed).

I am guessing the parameter name, and you might need to change the associated limits too.

Nothing happens on clockwise or anticlockwise -+ buttons = dead!

Will try to set scalemax and see what happens.

# ---Setup spindle at speed signals---

sets spindle-at-speed true

Is that a misspelling? sets = setp maybe ?

sets = set signal
set = set pin

Use halshow to check motion.spindle-speed-out-rpm-abs and hm2_5i25.0.7i76.0.0.analogout when using the GUI buttons.

They ought to work, (even with the machine not homed)
