Hi Guys and Girls,

Hi Guys and Girls, I am in the process of editing GRBL 1.1f to run on my lasersaur drive board running LasaurGRBL v14.03.

I have most things working, but have hit a snag with the pwm output. The port was changed from B3 to D6 (spindle_enable_bit), but the pwm still outputs on B3. Am I missing something? has anyone done this and are willing to share ?

Any help will be greatly appreciated.

As far as I know, it’s not so easy to move the pwm output to a different port because of the timer limitation. Would’t it be easyer to just make a pinout adaption board for the ATmega328 chip (as it is wrapped).
