Hi All,

Just about ready to print some good 3d parts.

Instead of a fan to remove heat from the extruder I would just use a temperature controller to regulate the power to it.  You ban build one on the cheap that just PWMs the heater current to maintain a balance between a set point potentiometer and a thermistor, resistance thermometer, or an amplified thermocouple.

Hi Mark.

It's in the G-code software already, I had it up too high at 245c.

The fan is to cool the plastic, the extruder heater has a temperature control.

This was a good print...

It looks like you are getting your rig dialed in.
