I will try switching the stepper drivers and see what that does. I have not adjusted anything other than the eSTEPS... I'm using stock Marlin 1.0.2 as per the build instructions. For testing, I am commanding it using Pronterface although the problem was there when I was trying to print a test cube from an SD card as well (that was before I installed Pronterface). I do not know how to control the extruder from the LCD.

I did check the stepper drivers and the one for the extruder was set to .647v (all the stepper drivers were at this high level) and I reduced it to .391v as per the troubleshooting pdf from Makerfarm but that made no difference.
Your enclosure is pretty damn cool... is that plexiglass?

I'm using Makerfarm Marlin. I tried the one that is linked in the firmware pdf and also the one that is in the Pegasus Software folder from the main build instructions (I think they are the same).
I tried switching the stepper motor driver between the extruder and the Y axis and now the extruder works fine and the Y axis won't move. That means I have a bad motor driver as far as I can tell...???

To control the extruder from the LCD:
Prepare -> Move Axis -> Extruder -> 1mm -> Turn knob slowly counter clockwise to feed.
I also read in the Makerfarm troubleshooting PDF that Marlin disables the extruder stepper if the hotend is less than 175C. I have not actually tested that.
I had the same piece of paper saying to change my esteps in the firmware to 102.3, but I actually did the estep test shown here:
My estep calculation came out to actually 105.6. I think I will run the test again.
It may not be providing enough amps to the motor. You will have to see how to adjust the current. I guess it has to do with that potentiometer.

Is the driver installed with the correct orientation?

And yes the firmware will prevent cold extrusion.

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.
