Topic: What Causes Protruding Corners?

My corners are never square.  They always protrude a little bit.  I tried dialing down the perimeter acceleration to 200 while keeping the other accelerations at 1000.  I could physically see the carriage slow down at the corners so I know it was working, but there was zero effect on the protrusion problem.  Is there a way to eliminate this artifact?  It forces me to have to shave down all of my prints which is not fun:(

Re: What Causes Protruding Corners?

I had read previously that it's related to speed, but in my experience, that's not the case! I would like to find out as well!

I imagine it has something to do with acceleration settings or jerk settings.  Though I do not quite understand the difference.  As I mentioned, I lowered the acceleration which had no effect.

Re: What Causes Protruding Corners?

I would bet more that its over extrusion on corners in your case, as the over extrusion is roughly symmetric. If it is speed related, only one wall of the conner will be protruding, not both.

Re: What Causes Protruding Corners?

increase jerk, which is the instantaneous velocity more or less. Lower jerk creates more ooze on corners.
