Banding/Wobble/Layer Shift

[sreisig1]

What is causing these lines?

This side was facing x axis



This side was facing y axis


this side is fine

Is this a z axis inconsistency issue? Found another thread on another forum where the problem was with a loose coupler. Where are the couplers located? Idk what to check

[curious aardvark]

slicer, speed of printing, temps. material, etc

Give us some kind of clue here :-)

Simplify 3D

2mm layer height, 205c, 60c bed temp, 2800mm/min speed

Doing it for another part now too that I'm printing at 1800mm/min

I haven't changed the files or settings at all and the parts use to come out fine. So it has to be a mechanical thing. Using the same x3g file I used a couple weeks ago.

I checked the screws on the carriage and the screws holding the bed to the platform and all are tight.

Sorry, and this is PLA

Was the good side facing the Z axis screw? If so I might bet it is a little dry. I had that happen on one of my printers that the Z screw was sticky and was causing the platform to shift slightly as it moved.

Yes the good side was facing the z axis threaded rod.

That's my guess then. That would be the side that would move the least if the bed platform pivots on the Z rod.

Thanks. I used a microfiber cloth with alcohol and wiped down the rod. Then applied some singer sewing machine oil to it. Attempting another print.

Did you oil the Z screw rod? That is the one that gave me an issue. Hope that is all it is.
