Prusa XLBuddy: original control board for Prusa XL

Prusa XLBuddy is the printer's main control board and an original replacement part for Original Prusa XL and XL+. If you need to replace the original XLBuddy, this part is intended specifically for that replacement. (prusa3d.com)

Part of the modular electronics

The XLBuddy board slides into the Sandwich board and the antenna cable is connected to it. Thanks to this arrangement, it is a separate component of the electronics, not a complete assembly of all the printer's electronic boards. (help.prusa3d.com)

XLBuddy controls communication throughout the printer. It works together with other control boards, including the toolhead electronics and the modular heated bed. It does not replace the Dwarf, Sandwich, or XL Splitter boards, which have their own roles in the system. (help.prusa3d.com)

During replacement, follow the service manual for the specific printer model. Before handling the electronics, turn off the printer and let it cool to room temperature. Correct connector wiring is an important part of the service procedure. (prusa3d.com)
