Hello friends! I have a hobian machine on the GrblHAL 1.1f platform, Lightburn does not work correctly. I put 100% of the power, it does not develop power. Tell me which postprocessor to choose in the device settings?

Problem solved! It was exactly as you suggested! $30=1000 solved the problem! Best wishes for health! [IMG_20250511_222739]

Thank you very much for your answer. A little later I will check, I will write to you about the result :handshake:

You grbl was pretty much developed for 8 bit machines. So a maximum value of 255 would relate to full power. Of course both the software and the machine have to talk to each other, they need to know what 100% power relates to PWM wise. We’ll probably see a change as most of the newer machines sup…
