Typically, shifting or slanting prints are caused by either a loose pulley or belt within the printer's gantry, or some kind of obstruction within the gantry.

We recommend looking to the back left and front corner's of the printer's gantry. 

If you follow the belt to these corners, you should be able to find two pulleys in these corners. 

Check to see if there are any fasteners or tape interfering with the pulleys or belt in these corners. You may need to shine a light in to help see these pulleys a bit better. 

If you see anything caught here, please try to move it out of the gantry's path. 

If you are unable to find any obstructions or are still having problems, contact our support team
