And yes the firmware will prevent cold extrusion.

I had no problems running the extruder with pronterface while the hotend was cold.

To control the extruder from the LCD:

Prepare -> Move Axis -> Extruder -> 1mm -> Turn knob slowly counter clockwise to feed.

Thank you

Is the driver installed with the correct orientation?

Yes

Same here. Pronterface will run the extruder motor with a cold hotend

My bet is blown driver. Had this happen to me right around Christmas on my 10".

Bought 5 spares for good measure. Plugged a new one in and right back printing.

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.

Agree with all that. Ask me why... ;-)

We are talking about the manual controls. If your trying to extrude with a cold hotend with everything assembled then you deserve to have to clean up a mess.

Doesn't matter. The printer still shouldn't typically be allowing it. Who knows - maybe pronterface IS sending an M302 when you manipulate the manual controls.

It shows the output I can look when I get home.

Good deal its been a while since ive used pronterface.
