diagonal line on print causing layer shifting?
-
The Ender 3 runs on v-rollers. You might have a flat spot on a roller or some dirt collection on the rails?
If it was real level shifting, you'd also see it on the inside, but it looks OK there. -
"What's the smallest Z step your printer can do?" To be honest I am not sure! they are just stock ender 3 stepper Moters. If it is something mechanical, I am not sure how it is consistent enough to travel up the side of the part like that.

@Phaedrux
I think these like pretty good. -
I was thinking something a lot larger/taller than that so you can start to see any repeating patterns.
Try a taller cylinder and conical cylinder in vase mode.
-
After more testing I Think I am getting z binding on both sides. This would explain why the artifacts do not travel straight through the part but rather make separate patterns on the wall closest to their respective sides while leaving the center looking ok.
-
So the way I have my z steppers hooked up the whole x axes hangs on it rather than pushing on it, does this make a difference?
this is how I plan to fix it I will a add linear bearings for the blue lines and then somehow mount the linear bearing cars to the x in a way that it can pivot so it can move independently. -

To avoid axis' binding, you need to fix one side while the other side can "float" in one direction to compensate thermal expansion.

@o_lampe I have been wondering about a core xz mod for it.
However I do not want to lose auto tramming Z! Do you have any thoughts on that? -
@o_lampe Something like this?
-
@53581 That'll do, but it's a bit overkill.
