Hey everyone. We have a CTC 3D Pro that apparently will not power the cooling fan from the EXTRA slot on the board. Does anybody know a way to turn on the power for the left extruder in Simplify3D when the printing starts, so we can power the cooling fan to the left extruder spot? There currently is nothing hooked up to the left extruder parts, we only use the right side.

Basically looking for a script line to turn on that left extruder when the print starts (or even at layer 3) and just keeps it on while the print is active.
