gr5, While everything you said is very useful and relevant..
I have seriously addressed every single statement you made in my pre-posts..
Since you have three unrelated problems (third issue being bottom layer skip backs) but think of them as the same problem and since the treatment for one problem doesn't fix the other 2 - I thought you should revisit the tension issue for the grinding issue and revisit speed/temp for the skip backs on layers other than the first layer.
A photo of the pattern in the filament (like the one I posted) would help convince me that is not your issue.
As for retractions.. My issues occur regardless of retractions.. it can seriously have been 2-3 min since last retraction and have skipping or back stepping on the extruder..
There you go again - retractions is unrelated to back stepping. It's related to grinding. The sooner you think of this as 3 separate issues, the sooner you can fix one or all of them. Although I agree that retractions is probably unrelated in your case - at least for these large interlocking parts.
