Good deal its been a while since ive used pronterface.

But just to clarify, the printer prevents cold extrusion, not Pronterface or other host software. Either the printer firmware has things set to allow cold extrusion, or the printer is receiving an M302 gcode command to enable it. IMO, allowing cold extrusion by default isn't a good idea.
I'm on hold yet again waiting for a new stepper driver in the mail. This is becoming very frustrating... I hate waiting for crap in the mail. Makerfarm may be very fast to respond to contact but that is a bag full of fasteners and 3 motor mounts that were not originally in the package and now a defective stepper driver right out of the box. I'm a little disappointed.
A new stepper driver fixed the problem.
