Geeetech Pursa i3 X Pro Y axis freaks out & doing nonsense

[jasperarrow]

i have fixed everything except that the Y axis freaks somewhere between 1-2 minutes after printing Ill seld you a video to see what im talking about.

On video I start printing 20mmx20x20mm cube and suddenly it started to print something that is not a cube.

So i have cilbrated everything except that in the beggining the extruder motor still blocks and the first layers are not fully covered with filament and the Y axis on every print after 1-2 minutes freaks out printing nonsense

On the video its clear what is going on if you do not understand the video ill make another one
