Funny Retraction Issue
Hello,
I have been printing for 3 months now with fantastic results. Until recently all of my prints with similar settings are having issues with one specific orientated corner (see picture). I am printing with PETG and by using a GCODE viewer I see that there is a funny retraction code around the corner. Here is a snippet of code and I have attached the rest below. I have the seam position on random to help keep the start and start in different places, but it keeps this similar code on both the part i'm making as well as the single walled cube in the photo
