X = grit rollers
Y = head
Z = pen
X-motor
Increase (+) the value to rotate the grit rollers forward.

Decrease (-) the value to rotate the grit rollers backward.

The X-motor should react at a PWM between 150 and 300 with the pressure

rollers down. If not, the motor is broken or there is a mechanical interference.
Y-motor
Increase (+) the value to move the head to the left.

Decrease (-) the value to move the head to the right.

The Y-motor should react at a PWM between 100 and 150. If not, the motor is

broken or there is a mechanical interference.
Z-motor
Increase (+) the value to lower the pen/knife

Decrease (-) the value to rotate the pen/knife

The Z-motor should react at a PWM between 150 and 300. If not, the motor is

broken or there is a mechanical interference.
