Taz 4 quivers printing round sequences

as stated, it shakes when printing a circle or rounded edge. I’ve observed it moving in X and y axis and it does not shake when doing either of those, only when printing a rounded edge. This causes the layer to come out squiggly along that edge. It didn’t do this yesterday. I tried printing multiple files and it will do this every time now. Any thoughts?

Yup, I’m seeing the same thing… No idea what it might be yet…

Are you using Slic3r, Cura or something else?

I am using Slic3r. I’m taking a good look at the motors, but they don’t seem to be causing the vibration. Almost seems as if its in the extruder assembly somewhere.

When in front of the TAZ, use your hand to grab the entire Extruder Tool Head. You should not be able to rotate the toolhead clockwise or counter-clockwise. If you can you may need to tighten the X axis carriage bearings. Loosen the screws holding the bearings, then slide them closer to each other, and tighten the bearing holders back down. The X axis should move smoothly and evenly. Try the print again.
