Printer offset in x-axis is wrong

[tim.sublette]

I have a felix 3.0. When the print head is moving back and forth in the x axis (i.e. a tall skinny part) The relative offset is not correct - like the motor or belt is slipping so I get a double image after a few layers and following layers are off by a cm or more. I have tried setting a lower speed on slice, increasing the tension of the x-axis belt, and tightening the set screw on the motor gear.

This happens on all prints. Any advice would be great.

Thanks,
Tim

I believe the x-axis belt was too tight. I loosed it up and it is now working fine
