Hi Guys,
So after having problems with my FETS on my RAMPS board I decided to build an external PCB with my new FETs on it. (2xIRFz44n for hotends and 2xIRLB8743 for heated-bed and possibly a heated chamber system)
The problem I am having now is mapping the pins correctly. I have had a look in pins.h and changed the values I thought were correct but it hasn't made any difference. I have confirmed my board is working on those pins with a modified blink sketch (turns each pin on and off), SO i know its something to do with the marlin code. I did try running them off the servo pins as I wasn't sure if marlin wanted the FETS on PWM capable pins.
Right now I have Marlin configured for board 33 but i do plan to use board 34 in future (EFB and EEB respectively)
Pins to be used are D63 - H1; D40 - H2; D42 - HB
Thanks in advanced for any help!
