This guide covers replacing the x-axis PCB (x-axis interface board) on the Fusion Edge 12, 24 and 36 and the Fusion Pro 24 and 36. The board is mounted on the rear of the x-axis assembly.
Parts Required
- LC0806 – PCBA, X-Axis Interface
Tools / Materials Required
- 5/32" Allen Wrench
- Phillips Screwdriver
- Anti-Static Strap
Safety First: Ensure the engraver is completely powered off and the power cord is disconnected before removing any panels or touching internal components.
Using the Anti-Static Strap
An anti-static strap is required when working with any circuit board in the Fusion Edge and Fusion Pro. It keeps static electricity from building up and discharging into sensitive electronic components.
Put the Strap On
Take the anti-static strap out of its packaging, place it around your wrist and adjust it so it is tight but comfortable.
Adjustment Clamp
After sizing the strap, make sure the adjustment clamp is in the closed position.
Clamp Closed
Clamp Open
Check the Fit
The strap should be worn as shown, with the small metal plate on the inside of the strap touching your skin.
Attach the Clip
Attach the alligator clip to a bare metal surface in the engraver, such as a screw through-hole, a side panel tab or the chassis. The preferred spot is the chassis bolt for the regenerative clamp ground, behind the right panel (red arrow).
