"Ghost prints" Cura 13.12

[jack-white 0]

Hello all. Just installed the latest version of Cura and got it set to the same settings as the last version of Cura.

First couple of prints went all right.

Now, something bizarre is happening.

I print something, doesn't matter what it is, and after a few layers, it will print another copy of the same thing on top of the first copy, but slightly off to the side.

What the heck?

Any help would be great, reverting back to 13.11.2 for now ^.^

Sounds like your pulleys are slipping.

I assume it is slipping only on the X or Y axis? Does that make sense? If not please post a picture because in that case I have no idea what you are talking about.

So figure out which axis it is and then tighten all 6 pulleys for that axis. There are 6 (six!) pulleys. The two most likely to be slipping are the two that are hardest to get to: the short belts ones: the one on the motor and the one above.

Tighten the heck out of those grub screws (aka set screws) and try again.

Also consider maybe marking the pulley and shaft with a tiny dot to see which one is slipping.
