Older 3D printers deserve love, too! The Flashforge Creator Pro from 2015 is an early replica of the MakerBot dual extruder. However, in 2024, it's due for an upgrade. I followed this tutorial https://msptrick.blogspot.com/2022/11/flashforge-creator-pro-control-board.html (no relationship to the author), but noticed that no model for the adapter is provided, so I made one.
The standoffs to mount the adapter to the FFCP underbody are snug, but still should be secured with M3 washer and bolt. The standoffs for the SKR E3 Mini are meant to take a heat-set insert. I used an M3 one to match the rest of the native bolts.
