I have a Lulzbot TAZ3
Recently I have been doing some maintenance. Now after putting things back together I cannot get the hotend to heat up.
I’ve tested my heat resistor, and it gives a normal resistance @room temp (around 5 oHm)
The bed is heating up normally
Next, I’ve traced cables all the way down to the RAMBo board, and nothings seems fried at the first sight. What would be the best way to test that Mosfet outputs?
And last, please feel free to give random proposals and solutions for what else could be wrong
