Hotends & Heated won't heat via software (2 replies)

Hi guys, I'd love some advice on my ramps board.

I can heat the hotend and heatbed by using the Preheat function of the LCD screen and everything gets as hot as it should be. When I try and heat them through Repetierhost they don't heat up.

Would this be a firmware config issue? A ramps hardware issue? Blown MOSFET? I'm stuck and this is the last thing stopping me from printing.

Thanks in advance
Alex
