I tested with a webcam taking a photo every Z change (= new layer) and found out that the shift is exactly at the 128th layer (printed in 0.2mm per Layer, but I think the high of a single layer doesn't matter). Maybe this helps with finding failures for the bad layer shift.
At the 128th layer ...

This firmware is much better than the stock firmware! However, i'm getting bad layer shifts. I can hear the Y Axis stepper clicking while printing the infill. I'm not sure what to do.
I guess i'll need to go back to the stock firmware. Does anyone have a link to the stock firmware in a hex file ...

And you can reverse the direction of the Z motor according to user manual:

Thank you very much, this helped me a lot, too!

Have you selected to correct voltage in the PSU (e.g. 230V in Europe)? There is a small rectangle hole on one side of the PSU where you switch the voltage with a iron clip or screw driver. But disconnect the power cable before you switch it.

Hallo MichaelK and 3D printing friends!

I could compile your Marlin 1.1.9 (downloaded from thingiverse) together with aarli's configuration files from the post on page 3 in this thread.
I used Arduino IDE 1.8.7 in Win10x64 and uploaded the firmware directly by USB to the GeeeTech A10.
