Quotefrankvdh QuoteVDX .The power is defined by pulse-length - so 0-5V analogue input to my drivers "set power"-input will result in pulse-lengths from 5 to 500 Milliseconds ,,, The input isn't analogue in the voltage domain. It's digital (TTL)... 0 or 5V. The analogue aspect is, as you say, in the time domain (PWM). The OP was talking about generating a 5V signal by using PWM to modulate the 12by boxed - Firmware - Marlin
I have a couple home built CNC machines. I would like to add a 12v/5v laser(like this ) to a SKR 1.4 board. I cant really figure out how to do this exactly. After a bunch of research I am thinking that i will use the fan0 for the pwm. Now i want to be able to use fan speed 255 as full power so I think that i have to go into the PWM fan scaling in adv. am I correct that a value of 106 shouldby boxed - Firmware - Marlin
