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.
