spindle_enable true If set to true, enables the Spindle module, which uses an encoder to PID-control a PWM-modulated spindle motor
spindle_pwm_pin 2.4 Output PWM pin (uses hardware PWM). Note : hardware PWM is available only on pins 2.0 to 2.5, 1.18, 1.20, 1.21, 1.23, 1.24, 1.26, 3.25 and 3.26
spindle_pwm_period 100 PWM period to use in microseconds
spindle_feedback_pin 2.6 Feedback input pin (must be Port 0 or 2, meaning the pin number must be 2.x or 0.x )
spindle_pulses_per_rev 3 Number of feedback pulses per revolution on the feedback input pin
spindle_default_rpm 5000 RPM to use if none given in M3 command, in rotations/minute
spindle_control_P 0.0002 PID P factor (unit is 1 / RPM)
spindle_control_I 0.0001 PID I factor (unit is 1 / ( RPM x seconds ))
spindle_control_D 0.000001 PID D factor (unit is 1 / (R PM / seconds ))
