Day 2. Progress? Kind of.
Solved some of the issues. No more Pritt Stick - the prints stick to the heated bed.
The worst of the X-Y Shift appears to be gone. However as can be seen from the bottom row, as soon as infill begins so does the crazy printing.
All apart from the second gear is Cura 14, and that is Slic3r 1.0.0.rc2. Just in case Cura was screwing up. But the same issue occurred.
I’ll return tomorrow…
