BossDelta300 heater fail

Post by geofbuck »

Does anyone know where the fuse is for the heater? I was told there was a 5A fuse on the duet control board but I opened up the base of the printer and I don't see one. There is only a blue automotive 15A fuse. Where else could it be located? My brand new unit won't even print. It fails when trying to heat before printing even starts.

The fuse locations can be found here: ... e_Overview

look at the "features" section - the fuses are shown with a red highlight and they're on the right side of the board.

I would also check to make sure that the connectors on the SE300 haven't come un-seated - even a little bit could cause an issue.
