SOLVED - Hotend & Heated won't heat via software

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

It's not RAMPS or MOSFET, since the LCD controller uses the same electronics to control the heaters as the PC . . . this is either firmware, or Repetierhost, and I tend to favor the latter . . .

What happens if you send gcodes to the printer directly, and not using the Repetierhost functions? And what do you get back from the printer from either attempt? Any chance you just aren't connected, or does movement work?

When you say directly, what do you mean? Through the manual control panel if Repetierhost? I will try and send some M109 commands tomorrow. When I run a print which has the heatup codes in it, it doesn't heat up. All the other things work as they should and gcodes for movement are fine.

Is it possible its stuck in Dry Run mode which ignores the hotend and heatbed?

Ok this has been solved. Re-uploaded the firmware and changed to Pronterface and i now have control of the hotend and heatbed. Thanks for your suggestion Tim.
