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 slic3r). 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.
While printing I noticed a lot of nozlzle dragging with support and solid layers
I got lots of suggestion about over extrusion,
now I don't think it's due to over extrusion.
I marked 120mm in filament and tried to extrude 100mm, but I only got 93 mm, so I had to change my E_steps from 90.95 to 98.02 to get 100mm.
SO If 90.95 had dragging then 98.02 will have more dragging, So what could be the cause?
Any idea what causing it?
P.S :I don't own a ultimaker, it's prusa i3
