X shift

I don't really know what the cause of the problem is. My printer was working fine since I built it until now. I was going to print a thin disk. Somehow, when the first layer was printed, it was in the correct location on the glass, but once it gets to the second layer, the X shifted. (See attached shifted.jpg.) I am not sure what causes it, but I think it has something to do with the belt tension. If I am correct, how much tension should there be?

check your slicer settings. this usually happens when the non-print movements are above 120mm/s

Also check your vrefs.

Thank you all for your replies.

Hi jrcaster,

I heard of ref a lot in the course of building the printer, but everything seems to work fine and I never bothered to fiddle with it, What is the proper ref for each axle?

Rich,
This is a very common problem.
