After 4 days of trouble shooting I have concluded the 2 of the MOSFETs are kaput.
Here is my question.
I am building a 3D printer. Using RAMPS 1.4 and a Mega.
Interestingly LCD works fine. I am able to load Marlin firmware but when I try to test the servos nothing
happens. I have re-flashed the bootloader. Still nothing.
I was able to load a diagnostic program that is not pointing to MOSFET failure.
To replace the MOSFET looks simple enough. My question is if I do that will there now be power at the
servo pin outs? or should I just buy a new board?
Thanks for any and all answers.
