Moving up the Z-axis, making spaghetti, then going back down.
The title says it all really. I was printing something, and then out of nowhere, ten minutes in, the printer does some weird shit and extrudes a bit of spaghetti on the print, moves almost to the top, prints some more in thin air, just to move down to the other side of the print and continues.. The only noticeable difference being, that it was a couple microns too high, as there were spaces between lines now. There is no blue "travel-lines" in the slicer (Slic3r PE 1.41.3+win64) that goes up there. The printer just decided it itself it seems.
The image is of the exact file on the SD card. I'll try printing the same file again after the printer cools and I can clean the surface of my greasy fingerprints. After that I'll update this topic with the results.

It happened again. It skips some of the infill, and then goes to the side, makes some "circles", goes up, makes more "circles", and goes on. It's not really circles, but roughly.

I opened Slic3r again, and moved the part, and made a new .gcode file. Now it worked. The part let go in one end because of sub-par adhesion, but no weird motions.

Strange. I'm glad you got it to work
