Anyone Know what has caused this?

[David Rowland]

not sure…
could be dirty encoder stripe…. computer screen wipes are good at cleaning them

Hows the Test print? all in the right order?

[Stafford Cox]

Yep, encoder strip is most likely, or the bar that the head moves along. As Dave says, give them a good clean and try again, failing that, it could be the Y motor on it’s way out or the bushings on the slider bar….?

cheers guys will try that

Dirty encoder strip or dirty encoder sensor. Clean well with isopropyl alcohol. If this is not working, reverse the encoder strip. It’s an easy operation.
Have fun!
