I could do 5 printing without problem
 
and now the shift is back.

anyone have any idea ??

@bounty, please fill the support form at https://zortrax.pl/support-form/ and attach pictures/video that will show your printer (axis rods, bearings, extruder), especially if anything looks unusual.

Check Bands, did you follow the guide exactly step by step?

Disconecting motors?

Not overtighted bands?

Allen screws tightened?

I have experienced this issue and found the issue but I will need to see the printer working physically.

There's  a procedure for adequate band tension but hard to explain.

hi,
