Hi everyone. Last night at around 10:30pm I started an overnight print job on Hermes. I was trying to print one of those snake/dragon toys with all the links. When I arrived today to pick it up, it seemed like the print job stopped SUPER early in the print process.
Nothing alarming was displaying on the LCD screen, and when I checked the fail stats page for the last print, I couldn’t find any info. What’s going on?
Another possibility is that the filament jammed due to frequent retractions. Flexible models like that often slice up with a lot of retractions, too many of them too frequently can cause a clog. If this is what happened, I’d expect to find ground up filament inside the extruder door.
This kind of failure wouldn’t result in an error, because as far as the printer knows, it did actually print the entire model.
That seems likely… According to Nick, it seems like the printer finished the print without actually extruding the material. Would that be an issue with filament? Or maybe the feeder?
Checking the filament path into the extruder door is where I’d start, cleaning out any ground up plastic on the gears. It’s possible the retraction caused a clog due to either too much or too little filament tension, a )( shaped notch in the filament that is currently loaded would also point towards this being an issue. If it’s not a extruder tension issue, then it may just need the clog cleaned out to print fine.
