Hi guys!
Last year I build a CoreXY printer from scratch as part of a university project.
I have a aluminium plate as my print bed and a silicone heated bed with 12V/ 250W. My power supply has DC 12V 50A 600W. When I tried to get my heated bed to work, the fuse for the heated bed got hot and the bed shut off after about a minute. By now I know that the fuse is not sufficient for a heated bed with these specifications.
I was able to print PLA fine without a heated bed (thanks to a PEI Sheet on my aluminium plate) but now I want to start printing ABS and I need the heated bed to work.
What do I have to change on my board? What kind of fuse do I need?
Any advice is appreciated.
Thanks!
Cathleen
