Layer misalignment or shifting???
June 22, 2016 03:24AM
Hi,

I was getting reasonably good quality prints from my 3d printer. Yesterday I printed a pretty large model with lots of support(0.2 mm layer cura slicer also tried slicer). It was a 25 hour print and at the middle of the print I noticed some layer misalignment or shifting(not sure which is). But I didn't tried to adjust anything since I didn't want to mess it up even more. But the finished print has lots of misalignment or shifting problems especially in area of solid layers. I printed another part which only has few supports(0.1 mm layer), it turned out good, no problems, then I tried a belt buckle with support which also has lots of layer misalignment or shifts. So i think this issue only happens when there's lots of supports. I re-tightened belts and slightly increased motor current for X and Y, after the first print.

Any idea what causing it?

Your stepper motor drivers are either getting hot, or getting just a tiny bit not enough current.

When printing, monitor their temperature with a thermocouple. If they are cold, slightly increase the current. If they are hot, add some heatsinks and cooling fan.

I tightened the belt and increased current, but I don't think that's the issue

Actually my nozzle was dragging the supprot when I was printing, So I thought may be I'm over extruding.

I checked E_steps
Tried to extrude 100mm but to my surprice it didn't
I had to change my E_steps from 90.95 to 98.02 to give 100mm

If 90.95 had dragging 98,02 definitely have more dragging,

So what could be the issue?
