Fuse mounting panel used to mount fuse holders.I did this to my machine after blowing my poly fuses using 24v. Know your machine. Know your capability. Proceed at your own risk. I removed the blown fuses from the RAMPS board and replaced them with a jumper (See Jumper pic). The fuses are wired in between the power supply and the RAMPS board. I put a 10A fuse in line with the 11A input to RAMPS. I put a 5A fuse in line with the 5A input to RAMPS. The printer powered right up and has been running happily for many prints. After designing the panel to a close tolerance, I had to open the holes slightly after printing. I did have to print with support.
