Hello,
so i decided to build back my 3d printer and i am facing a problem with my sanguino (rev 1.3a if i'm not mistaken)
The j-head doesn't receive any power.
The board looks in good state, nothing burned.
If i plug the j-head instead of the heating bed, it works fine.
The mosfet looks good but i'm not sure how to test it properly, it doesn't give power because it doesn't receive the +5 or -5v on the gate (?)
So i was thinking maybe there is a problem with the firmware.
I uploaded a new marlin, it didn't change anything. I can't find (configuration.h ? ) if there is a pin assigned in the firmware to control this mosfet ...
If something is burned somewhere it would be nice to use the mosfet for the heatbed to the j-head instead so i can at least print.
I'm a bit lost, what should i do now?
