The HS+ is the 1.2mm nozzle. I’m experimenting with printing several smaller parts per print for objects that the resolution doesn’t matter. The specific part is a paint/stain mixer in the Thingiverse link below. I feel I should note that when printing single, larger parts, I have NOT had issues with stringing using the HS+ toolhead and have had very good results. It’s when printing smaller, more intricate parts, that I’m having issues.
I had a significant amount of stringing on the first print but reduced it a lot by changing from “print all at once” to “print one at a time”. I then started increasing the retraction setting. I ramped it up to 6mm and 30mm/s.
The stringing is substantially better, but it’s still there and I think the retraction setting being so high has impacted the print quality.
The question is, is there another knob I should be adjusting when minimizing stringing? If I’m throttling the retraction, do I need to increase something else like flow rate? or perhaps decrease print speed?
