Hello Wolfgang,
I have the same setup as you and I am trying to figure out some things. I’ve read your post here and also your other post here (I’ve re-read that whole thread at least 10 times as all the info there was very confusing and sometimes conflicting with each other and I am still not fully sure I understood everything 
). Anyway, I see hat you have connected your SKR 1.3 differently than others have suggested. You use the PSU IN pin to control the power instead of PWM’ing the L pin.Which makes sense to me, but still unsure of some things.
So I have a few questions, if you don’t mind.
- If you have PSU L connected to HE1- (pin 2.4), I assume in config you have that assigned to switch.laserfire.output_pin, correct? Is it as “2.4!^” ? And any reason you are using (-) pin 2.4 instead of 2.3?
- you have PSU IN connected to servo pin 2.0, correct? And in config it’s assigned to laser_module_pin?
- how do you use the config-get and config-set to edit the config file? You mentioned it but I can’t find any more information.
Do you still have your original digital panel with added manual potentiometer connected to the SKR board (to lower the power manually if needed)? Or do you control power exclusively with the Smoothieware config? With your setup, I am really not sure how could I connect that panel, because originally the output of the panel goes the PSU IN, but now the servo pin goes there. Unless I am missing something.
And do you think you could share your config file with me? It would make things much clearer to me, I am sure.
Thanks,
Mark
