Strange Layer Shift - photos  

RE: Strange Layer Shift - photos

Some common causes of layer shift:

* Pulley screws on X motor not properly tightened. One has to be tightened against the flat side of the motor shaft!

* Belt not correctly tightened. Use this tension meter to get it right: https://www.prusaprinters.org/prints/46639

* X carriage over-squeezed. Loosen the back plate on the X carriage axis.

* Nozzle hit an obstacle. Some patterns such as grid have lines that cross within one layer. This can lead to little pile-ups at the intersection points, in particular if you have slight overextrusion, which in turn can lead to the nozzle catching at those pile-ups. See https://help.prusa3d.com/en/article/infill-patterns_177130/

* Zip ties on the wire bundle on the back of the extruder not properly positioned, so they or the cables hit the model.

Thank you for the ideas, Just now, another Slug had the shift on a -different- mini and this one has the Bondtech extruder mod.

Here was my gcode and 3mf Zipped:PRUSA

Here are new photos, could it be those segments slipped on the plate?I clean with ISO before every print. Thank you

I don't see anything wrong with the 3mf file, so it's either a mechanical issue such as the ones mentioned before, or adhesion to the plate. Give it a good scrub with lots of hot water and dish washing soap. IPA between prints is good but every now and then the plates need to be cleaned thoroughly with soap and water. Normally I might suggest trying to print with a brim but that sort of defeats the idea of an articulated model...

Thank you for taking your time to help me. I did wash my plates with Dawn and a micro fiber and printing again.
Fingers cross!

So after cleaning the plate with Dawn soap and reprinting with the SAME gcode I got a much NICER print!
With no slips or shifts - Happy!

Good for you!
