Pen Plotter Config

The Pen-Lift version of the grbl firmware needs to be installed.

• Once the board is flashed, disable laser mode $32=0
  • If laser mode is enabled, it won't trigger a pen lift between white space and mess up your awesome drawing!
  • Pen-Lift GRBL version supports M3/M4/M5[http://linuxcnc.org/docs/html/gcode/m-code.html#mcode:m3-m4-m5] spindle control
  • The servo position will be proportional to the power setting used. For example (assuming $30=1000 in grbl config):
    • M3 S0 or M5 is servo at "neutral" position
    • M3 S500 is half extended
    • M3 S1000 is full extension as defined by RC_SERVO_LONG in spindle_control.c

• Created a new Device in Lightburn called "Pen Plotter"
  • Controller type 'GRBL-M3 (1.1e or later)'
  • In Device Settings, Set S-Value Max = 1000

I had to invert the Servo direction in grbl config.h
