Topic: mother board problem
I fixed the R271 with a dob of solder and a inline fuse. When it was altogether I started a demo print and the inline fuse I added blew...grrr ... have checked the repair plus the connector and can't find the problem. When I test the extruder heater plug off the board I get a beep from the multi meter so I have continuity there.
Once the MB is back in place the screen lights up as usual and then when the extruder goes to heat up the inline fuse blows again. I'm at my wits end and still can't find the problem. Any ideas anybody??
