I’ve build a 50W CO2 Laser CNC with smoothieware on SKR v1.4 board.
I’m at the optimization step of my system and am trying to search the maximum acceleration with the less vibrations.
My problem is that it look like Smoothieware is ramping the laser PWM during the acceleration instead of putting directly expected PWM value. (the same system as M3/M4 command on GRBL).
unfortunately when acceleration is too low, the ramp of the PWM is too low and there is unburned portion on my cut.
Is there a way to adjust the pwm ramp or to disable it?
