OK, so I’m having trouble re-printing a part. I printed this part a few weeks ago, and it was by far the best large print that I’ve done. Since then, I’ve tried 5 or 6 times, and it’s always failed as it makes the transition from the large horizontal bottom to the vertical sides. The failure that I see is that the filament stops feeding. The hobbed bolt then grinds away the filament, and nothing else is extruded until I cut off the filament and re-feed.
When I correct the problem, I pull the filament out, cut off the last couple of inches, then push it back into the extruder by hand. I’ve never seen any blockages in the nozzle, so I’m not sure what’s causing the problem. I’ve taken a picture of the part, and attached the stl file and gcode. Anybody have any thoughts on what else I can try?
