Rostock MAX v2 Assembly Guide
To square the tower, you'll need to push or pull the top of the tower in order to get the long arm
of the square to contact the bed all the way across. You'll need to offset the angle of the square a bit to
keep it off the Kapton tape in the center. Once you've got it square, tighten the screws using a 5/32"
Allen wrench using the pattern shown below.
