Tips
1. The distance from the left and right Y-axis sliders to the retaining base of the rear module must be equal. This prevents
the X Axis sliders from binding and keeps the X axis aligned at 90 degrees to the Y axis.
2. The machine will get stuck when the distance from the left and right Y-axis slider to the retaining base of the rear
module is different. If this occurs, please power off the machine and adjust the distance using the manual jog wheels.
3. If the machine gets stuck or is making unusual noises, check and confirm if the distance from the Y-axis sliders to the
retaining base of the rear module are equal or not.
