warm cobalt
Not sure how to describe the problem I think I'm having, but sometimes when I'm printing the filament "leaks" and can pull and catch on other filament that's been laid already or worse. It seems particularly bad when trying to make multiple small shapes to start with like you see below, but the other day I printed 4 square shapes just fine in the same print.
Attached is the aftermath after a suspected incident. Fresh PLA, first layer speed is 40mm, Nozzle 215° C, Bed 65° C, layer height for this print is .3mm . Stock Prusa i3 MK3S+ (but self assembled a year or so ago).
While I don't have a picture on hand, there have been a few times when the initial "wipe" of the filament (in the bottom left) takes place, but then, as the nozzle moves to the center to draw the brim, there'll be a streak of filament that is left in the wake and sometimes continues into the print causing scorching or failure of the print.
I'm really not sure if it's a settings issue. I've played a bit with retraction but it didn't seem to help or hurt. I'll be happy to provide the settings in whichever way is most convenient.
Any advice on some things to check and test would be appreciated. I'll give any info I can or if a test print of some kind would be helpful, I can do that as well.
