- Implemented USE_SPINDLE_SERVO_MODE configuration option - Changed Timer2 prescaler from 1/8 to 1/1024 for ~50Hz servo frequency - Added configurable servo pulse width range (SPINDLE_SERVO_MIN_PULSE/MAX_PULSE) - M3 S0-S1000 now controls servo position (0-180 degrees) - M5 positions servo to maximum position (pen up) instead of disabling PWM - Default configuration supports pen plotter with reversed pulse values (MIN=31, MAX=16) - Only supports ATmega328p (Arduino Uno) processors Based on: https://www.buildlog.net/blog/2017/08/using-grbls-spindle-pwm-to-control-a-servo/

this is my curennt grbl state
|
|
|
|
when homing the first limit switch encoutnered always retrun from homing.
|
|
it can be either the x or y
|
|
how to fix
|
