The ptfe tube that pushes up against the nozzle was worn out so once I replaced that (Luke's hotend fix) and put a brand new nozzle I went back to the regular retraction distance of 5 mm and everything is back to normal. You really need to print fast or it won’t have consistent line width. Worse, retracting too much filament can cause deformation inside the extruder assembly, which can result in a clogged nozzle. One thing I noticed is that the heatbrake has to extend further than recommended with the stock nozzles. During printing, the extruder pushes the filament into the hotend, where it will be melted and extruded through the nozzle orifice. I then mounted the CR Touch to the Sprite and connected one end of the little CR Touch cable. 6 nozzle can print more in the same amount of time. Changing Your PLA 3D Printing Filament.
