After returning my V2 and getting the V3, I am having a hard time liking it. The filament path is horrible and I am having a hard time finding the sweet spot for retraction and tool change. Right now I am trying to print a batch of small clips that need PVA support, but the main extruder (E1) keeps jamming around mid way through. Its almost impossible to get the filament out or to get it to extrude. I was finally able to push super hard to get it to extrude out whatever was snagging in the body, preventing the removal of the filament.
Maybe I need to disassemble mine and check the green extruder body that the filament goes through. Maybe something isn’t alligned or the path needs to be cleared of filament from the factory print. Even after cutting the filament at an angle and working the filament into a curve, it’s still super difficult to get it in to where the filament will extrude.
I guess my questions is: What are retraction settings that others are using with good results? speed, distance, min length between retractions. Also what about tool change? I want to minimize ooze, but don’t want to go back too far to where it will catch when going to print again.
