How laser PWM is calculated / am I loosing power resolution?

Hi there team,

I have a laser cutter module that will only fire properly (start marking) at about 20% duty cycle. So in the config file I set laser_module_minimum_power to 0.2 and laser_module_maximum_power to 1.

My question is, since we only have 8 bit pwm (0 to 255), is doing this reducing my power resolution? Or does smoothie recalculates/remaps the pwm values so I still get 256 steps between 20% and 100% duty cycle?

Thanks for your help.

Kind regards,
