Hi all -
I have a Mendel90 printer, and have swapped out my Sanguinololu (Sprinter firmware) with a Shiny new Rumba w/Marlin firmware, and have made all the updates to connections. I have a new 24V power supply as well, and motors and heated bed are working fine. My hot ends (he0, he1, he2) and fans (fan0, fan1) don't appear to be getting any voltage when I turn them on via Repetier. I checked the board, and each has a green status LED that comes on when I enable each, but not voltage. Did I miss setting something up in confguration.h in the Marlin firmware? It seems funny that both the hotends and the fans don't work - is this a 12v regulation thing? BTW, I am using v1, and can compile and upload firmware to Rumba no problem.
Any help on this puzzle would be much appreciated!
Thanks,
Rob
