UPDATE:
Hi,
It seems that my hot end and the bed are no longer heating. I have 12 volts on each connection.
I’m not sure what is going on. I spent 10 minutes testing before work and a few hours this evening. Now that I have two Wilsons, I have visually compared the wiring and swapped power supplies.
Which component on RAMPS controls the heating? Did I ‘pop’ something?
Thanks
