New GShield big frustration

Hi all,

I burned the gshield myself due to a wrong installed coolfan. This was a month ago. Ordered a new gshield true the European vendor.I ordered a new gshield (v5) and have to flash the grbl with the Arduino software, upload succeeded. After I used Paul Kaplan his HexUploader to upload the right .hex. I checked all my wiring twice. I can say that the Z axe is moving correctly, the X an Y only move in one direction true the machine setup. Please will someone help me, I don’t really know what to do any more.
