Hi Owen,
I think I just discovered the problem during your maintenance tip.
One of the pulley's was loose.
So thank you!

It's rare to shift in X *and* Y at the same time but possible. I would first tighten the tiny set screws on all the pulleys. I believe there are 6 for each axis. The most likely are the 2 pulleys for each axis on the short belts (motors).
However is it possible that your part came loose during printing? Was it still stuck to the bed when the print was finished? If not then you can improve the stickiness of the blue painters tape by rubbing it with isopropyl alcohol. This will increase adhesion by about 100X.
Someone else had a very similar problem this week and claims they fixed it by re-installing the firmware (using cura of course). This seems bizarre but their experiment was repeatable.
Hi gr5,
Thank you for your help.
At the moment it seems to be that the loose pulley was causing my problem.
The part did not come loose during the printing.
I'm going to try your tip with the isopropyl alcohol.

Hi dendrortyx
Can you move the head around reasonably easy by hand?
Have you oiled the shafts etc.?
Checked your speed settings in your slicer?
It doesn't hurt to reinstall your firmware.
Maybe your stepper motor driver needs adjusting, be careful if you decide to do this however (see the wiki)
