What are people having success with for the tool change retraction amount? I assume my issue might stem from that, but also maybe heat creep?
I am getting pretty consistent failures on dual extrusion prints. After about 4-5 layers into a job, the filament stops extruding, roughly around the same time and typically on both nozzles. After examining things, it appears there is a very slight (I mean really small) amount of grinding that occurred. It seems that the filament might be getting jammed somewhere along the path to the nozzle. I have tried tool change retraction in Simplify3D @ 13mm. It seems that Cura 2.6 has somewhere around 5mm out of box.
I am running another print right now from S3D with 6mm tool change retraction. We’ll see how it goes. The frustration is starting to grow. I just returned the turd that is the V2 DualMetal and was hoping to have better results with the V3.
