Floating Backplane Upgrade

Applies to: Fusion Pro 32 • Fusion Pro 48

This guide provides step-by-step instructions for upgrading the floating backplane board in Fusion Pro 32 and 48 engravers. Designed for models manufactured before mid-2020, this procedure ensures proper installation and configuration of the new backplane board. By following these instructions, you can safely remove the old backplane, install the updated components, and program the system for optimal performance.

   Power down the system completely before starting the procedure.

2. Disconnect power:

   Unplug the engraver from the power source to ensure safety.

3. Remove all connection cables:
