I didn't see a Config_overide..g

@dc42 On the pins where the heater plugs in. I turned on heaters, and checked it before I got a fault and it shut them down.

The power supply is set to 115, and it was working sometimes but would drop off hour into a print. According to the M122 says min 23.3, current is 23.6. On the board its self is 12v.

I have a M3d Crane with Duet 2 I believe. Started having issues with my heater it was moving up too slowly no matter what I do. Seems Its been having this sue for a while and would stop during prints. Now it will not go over 50c before I get a fault. Its supposed to be a 24v heater but its only getting 12 volts so I get why its not heating up fast enough. I have traced it back to the board and its only putting out 12v. I have checked wiring and its all correct. So where do I start?

I had the same issue today... I have 2 of them machines so swapped the sd cards and it worked.. So got a new sd card and that fixed the issue.
