So like the title is saying. My A10M is screaming Max bed Temp. it does this even when i unplugged the heated bed.
I was changing the nozzle when it all of a sudden start doing this and i can't see anything wrong.

any advice?

have this machine for over a year now and it's one challenge after another.
it has never been perfect!

Hi, Do you mean that when you unplug the hotbed cable from the mainboard, it still shows a high temperature?
If so, there may be a problem with the motherboard. You need to replace the motherboard.

Yes that what i mean.

that will be the 3th MB i have to replace. so Game over for this boy. Not gonna throw my money down for this printer anymore. will be a good one for spare parts.

thanks for your reaction.
