I am not sure about that. The part was printed correct ~3h out of 4h. I did a little bit of research and probably it's an different problem. After 3h the stepper motor driver ICs overheated and stopped working, maybe some seconds the running move-signals are ignored. After that the print is shifted...

Turn it clockwise a quarter turn. This will give a good starting point for finetuning later. from Instruc...

I've done the following: - swapped the leads in the Arduino from x,y,z to the extruder motor and it is good. - changed extruder motor to the spare motor controller on Arduino (I don't have a 2nd extruder), still a problem Did you: "Important note: The potmeter (little screw) on the stepper drivers ...

Try Arduino IDE 1.6.5

Slice with SFact
2_1_Normal_quality_no_support
PLA 1.75mm color RED
Print Temp 170-240C
Feedrate 100

First reduce the distance between Hotend and bed, use a sheet of paper.
Second try a Feedrate of 50%, to see if the extruder has a problem?
