...
Removing the ECU/Driver Pack | |
|---|---|
Make sure the rocker switch on the back of the ECU is on the 0 for off. | |
Unplug the power cord. | |
Disconnect the male end of the board cable from the back of the ECU by turning the locking ring and pulling gently. | |
Unplug the USB Cable from the back of the ECU/Driver Pack. | |
Secure the Gantry: Loosening Drive Belt | |
|---|---|
Move the gantry to the right side of the board about two feet from the right edge (to leave room for the packaging foam corners). | |
Remove the 5/32” Allen screws and washers from the lower gantry plate. | |
Locate the 3/16” Allen belt tensioner screw that’s located on the right bottom side of the lower rail and marked with a red dot. | |
Loosen this screw one turn only so that there is some movement in the belt tensioner. The tensioner springs should be visible. WARNING: Make sure you do not over-loosen this screw. One full turn is usually sufficient. | |
Locate the belt tensioner hole on the end of the belt tensioner. Place the 5/32” Allen screw and washer we removed from the lower gantry plate into the belt tensioner hole. Tighten the Allen screw until belt tensioner is flush with the rail and the springs are not visible. | |
Go back and tighten the 3/16” Allen belt tensioner screw. | |
Lift the drive belt end out of the belt tensioner slot. Pushing the drive belt end to the right may assist in getting a hold of it. | |
Wind up the drive belt, and rubber-band it. Repeat steps 4 through 8 with the upper rail. | |
Secure the Gantry: Remove Stop Plate | |
|---|---|
Move the gantry far enough to the left to dislodge the belt anchors. The belt anchors are sunk into the left ends of the rails and are attached to the drive belts. See the instructions following for the type of Gantry Stop your machine has. | |
Magnetic Stop | |
|---|---|
Loosen the top 3/16” stop screw of the Magnetic Gantry Stop. | |
Lift up the magnetic stop plate to disengage the pin from the hole and slide the alignment plate to the left end of the rail to remove. | |
Silver Gantry Stop Plate | |
|---|---|
Remove the right front 3/16” stop screw of the silver Gantry Stop Plate and set aside. | |
Loosen the back left T-Nut screw and slide the alignment plate to the left end of the rail to remove. | |
Stop Screw | |
|---|---|
If your model only has a Stop Screw without the alignment plate, remove the stop screw. | |
