Prints start printing off axis halfway through

[scottyshu 0]

This has been a problem for a while now.

Whenever printing anything more than a few centimeters tall, the printer shifts and starts printing in a totally different position than where it started. Usually finishes the print, just in a different area than where it started.

To clarify, the misprint is where the "M" gets cut in half about halfway up.

Picture of example attached.

See 4th image down on the left.  Sometimes this causes leaning - sometimes sudden shift exactly as shown in  your photo.  This is very common and easily fixed in a few minutes.

Most likely it's the pulley on the stepper motor.

Thanks, that's a very helpful resource to have! Didn't know it existed!

Turns out the bars were slightly not even and causing the belt to slip.

Consequently it looks like they've worn down a few of the notches so I'm going to have to get a new belt to replace it with.

They cost about $1 each in batches of 10 so go for it. fbrc8 might send you a free one - don't know. Doesn't hurt to ask.
