Hotbed suddenly stopped working
Posted: Wed Jan 09, 2019 12:27 am
I have a classic M2 with the dual power supply. I was happily printing on Sunday, but on Monday the heated bed didn't warm up, and it hasn't had any effect whatsoever since. I turn on the heat, and then there's no change in the temperature.
The external big PSU for the heated bed (12V 18amp) has an LED displaying power status, and this LED is on. I haven't ruled out that it's dead though - but I don't know why this would be the case.
The big PSU seems to be well connected to the RAMBo. Like I said, it worked the day before, and I haven't moved anything.
I inspected and replaced the 15amp automotive fuse on the RAMBo, but this didn't change anything.
The connectors from the RAMBo to the heated bed seem to be inserted ok.
What am I missing? Has something died on the RAMBo? Is my big PSU dead? If so, what's a good replacement? Or do I need to dig up my voltmeter and start measuring to figure this out?
