In this lesson we’ll walk through replacing the Epilog Zing Table Motor.
Preparation
Start by lowering the table to the bottom of the machine by pressing focus then the down arrow button.
Shut off the laser and remove the power cord from the machine.
Inside the machine, move the x-axis assembly to the rear of the machine.
Put on the anti-static strap. Clip the strap on to any metal part of the machine. Always wear the anti-static strap when handling the control board to avoid damaging the unit through static discharge.
Remove Right Side Panel
Loosen the two screws on the side of the display panel.
Grasp the two screws and pull the controller away from the engraver. A small amount of force will be required to remove the board from the machine as you disconnect the electrical connections.
Make sure the copper strips inside the control housing stay in place when you remove the board.
Next we’ll remove the right side panel from the machine. Remove the three screws on the side of the machine.
Remove the screw on the back of the machine holding on the side panel.
Remove the right side panel by lifting up on the bottom of the cover and pulling toward you, then up.
Remove Old Table Motor
On the bottom right side of the machine you will find the motor. Using a short screwdriver, remove the four Phillips head screws on the motor bracket.
Follow the wire harness from the motor and disconnect the harness from the backplane board in the upper right corner. Cut the zip ties.
Loosen the black-capped tensioning screw located in the bottom right side of the table on the inside of the machine.
Remove the motor assembly from the white table belt and set it aside.
Access Bottom of Machine
Tape the top window to secure it, and then carefully tip the machine on its left side, opposite of the open side, so you can access the table motor from the bottom of the machine.
Using a flathead screwdriver, carefully pry the panel from the bottom of the chassis to remove the six plastic securing pins. It is best to start from the top left and work your way down to the bottom left. Then from the top right, work your way down to the bottom right.
Install New Table Motor
Place your new motor through the hole and wrap the white table belt back around the motor assembly, making sure the belt is wrapped around the pulley. Loosely install one of the Philips screws on the motor bracket to secure it, this way it will stay in place when it’s time to flip the machine back down. Do not over-tighten the screw.
Reinstall the bottom panel of the machine. Use the replacement securing pins included with your new motor. Push the pins through the holes on the bottom plate tightly into place.
Carefully lower the machine back to a level orientation.
Remove the tape from the top window.
Loosely install the remaining three Phillips screws on the motor bracket.
On the side of the machine, gently pull the motor to the right side of the machine, putting tension on the belt as you tighten the black-capped tensioning screw until it is finger-tight.
Tighten the four Phillips screws on the motor bracket.
Plug the motor wire harness into the backplane board. Optionally, you can resecure the harness to the other wires using a zip tie.
Reinstall Right Side Panel
Replace the right side panel, tightening the three screws on the side of the panel.
Tighten the screw on the back of the machine.
Slide the display unit into place, ensuring the tabs on the control unit fit into the grooves on the side of the housing. Push the display unit all the way into the slots until it is fully seated. Tighten the two screws to secure the display unit in place.
Plug the machine in and turn it on.
Test Proper Functionality
Press the focus button and use your arrow keys to see if the table is moving properly.
