GT 2560 board Heated bed not working - 7 years ago
Hi. I have one of those i3 prusa variants from eBay and I think it has the GT2560 board. Recently the heated bed stopped warming up. After a while I noticed a burnt patch on the electronics board. Attached. Is this a blown fuse or do I need to replace the board? Thanksby arleseydiver - Prusa i3 and variants
Re: Chinese eBay 3D printer - Story so far, and request for advice - 8 years ago
Hi, I've recently just bought one if these as well. I am having similar problems with the thermistors, and rasping on the extruder. When the item arrived, the rods were bent, and the holes had been cut in the wrong places on the frame. Does anyone know if it is possible to backup or download the running firmware on the gt2560 board? Rogerby arleseydiver - Prusa i3 and variants
