I have a Problem by using the home Operation.
The movement goes not in the Corner and the Motor give a non natural Sound.
On the Display is: Endstops hit y
Can you help me?
There are a few things you need to do.
Check the the reference voltage on the drivers.
The manual says 0.425 however 0.55 is the sweet spot.
Do not go over 0.6 because this will make the driver over heat and do stupid stuff.
Check the soldering on the Y axis end stop.
Also if the wires (for the end stop) are rubbing on the back of the frame put a cable tie on them to stop that.
You may need to upgrade the firmware.
The first version monitored the end stops after starting the print job.
This caused false end stop hits and shifting layers.
You can get the firmware from this link.

Also use Arduino software 1.0.6 or below.
You can download it from here.
