CR-200B Marlin Led control
I own a CR-200B enclosed printer . after solving the "filament eating problem" by adjusing the stepper motor currrent, the printer works great.
I like to edit the Start-G-code and the end G-code in Cura to turn on the Led by starting a print , and turn off againt when printing has finished.
I tried to edit the start code with
M42 P6 S255 ; led on and M42 P6 S0 ; led off but nothing happens .
Can someone help me out with this please?
