Awful First Printing

Does anyone have an idea what could go wrong? The wizard said everything was fine and I tried to calibrate the z axis many times..

Best Answer by Steve:

I agree. Something is loose. Belts loose enough to cause that much error should be obvious. The next place to check is the set screw on the motor pulleys.

Check that the X and Y belts are correctly tensioned. Loosely tensioned straps can cause a very poor finish.
Also check that the drive wheels (timing belts) are securely fastened and do not come loose.

Apparently a screw in the Y axis was not tight enough. Amazing how one screw can change everything.
