Thanks for taking the time to look at this post.
I have a reprap which i have rebuilt and have used a new greg wade extruder. The previous extruder was one where the gear feed was on the side and it fed the filament via a tube. It never ready worked and chewed up the filament. At least now i have a positive action on the filament, but the Pronto softwaree is working in the wrong direction. Pressing extrude get reverse and pressing reverse gets the extrude action. is this a firmware problem , do I have to rewire the stepper motors. Also my x axis stepper now will only home in the wrong direction away from the optocoupler.

Any suggestions please what to do.

regards Colin
