ELECTRONICS PROBLEMS

Hi,

I have a Felix 3.0 dual extruder printer that I assembled myself from the kit. One extruder is working fine; the other doesn't heat. For the one that is working, the measured resistance is very low, and the one that is not working is very high. Which seems to make sense. The question is, what do I do now?

Also, the display powers on but just gives me a blue screen.

Any suggestions would be gratefully received.






I didn't find the right solution from the internet.
