How do I replace Y Axis Motor?
Replacing Y-Axis Motor on a Mercury Laser machine.
Open the passthrough door -
The two red circled screws hold/lock the motor in place when adjusting the tension - the two blue circled screws also hold the motor in place - Remove all 4 to slide out the motor.
The green circled item is how you can adjust the tension on the motor/belt.
