I’ve done several multi-hour prints that failed hours into the print because the filament gets stuck in the chamber and quits feeding. This never happened with the single extruder because the channel was straight so the filament didn’t have to go through any gymnastics to make it to the nozzle. For some reason this head was designed in a way that requires the filament to have to significantly bend to feed. I’ve used the jig to tighten the screws to the right distance but it didn’t matter. I tried a few turns tighter but it doesn’t matter. Tightening these screws and the curved chamber also makes it way too hard to load filament. Most of the time I have to untighten the screws to be able to hold it open to load, which then has me counting turns to get it back to jig depth. This seems like a bad design to me.
I’ve wasted days and 2 spools of filament on this V3 head between the temperature issues recall and these feed problems. I wouldn’t be so mad if it would screw up instantly so I didn’t stand around waiting hours for a 15-hour print and have it suddenly get stuck 2 hours into the print.
Is anyone else having these kinds of issues?
