This MOD arises from the need for active cooling on the Toolhead Board CAN (Huvud v0.61, Fly SHT42 and BTT EBB42) for VORON2.4 350 Afterburner with cable chain. When printing ABS or other materials, with the doors closed the Toolhead Board CAN reaches temperatures around 70/80 degrees. In my case the Board went into ERROR_MCU thus stopping the print in progress.
