This guide covers replacing a y-axis bearing block assembly on the Fusion Maker, Fusion Edge and Fusion Pro 24 and 36. The x-axis assembly is lifted off the bearing blocks, and the y-axis assembly is removed from its guide rail supports.
Parts Required
- Y-axis bearing block assembly (varies by model)
Tools Required
- 5/32" and 7/64" Allen Wrenches
