XYZ cube's layer is shifted, How can I check my TEVO Tarantula axis? I just bought new TEVO Tarantula and tried to print xyz cube. I found that my cube's layer was shifted as showed in picture. How can I fix this ?
The two most common things to check:
1) make sure your belts are properly tensioned.  If there's significant slippage in the y-drive you could get the results seen.
2) Make sure the base layer is well attached to the base plate. you've got plenty of reference pattern on the plate shown, so check whether the lower chunk of print moved relative to the imprinted pattern at some point.
