Hot end doesn't heat up with Repetier (4 replies)

Hi

I'm new to using Repetier (was using Pronterface). I struggling with heating the hot end on my Prusa. I've dug through all the settings and just can't fathom why this strange phenomenon is happening? Heat bed works fine and Hotend works when I switch back to Pronterface? Anyone any ideas please? Happy to post any screenshots as required.

Cheers

Jamie
