Solved Calibration Issue

Just got the printer last week. Been printing like crazy and the last few prints have been doing some weird stuff.

So I went and decided to print the calibration box.

The bottom of the box doesn't have any straight lines.

The green bottom is from an earlier print. All of these have been printed using Matter Control on the standard Medium settings.

Any ideas?

Thanks
Gary

 

Found the fix on the forum. The Y-Axis belt was loose.

Tightened that belt up and it came out perfect.
