Topic: Extruder is knocking

My extruder just started knocking.  It back lashes 1/16 of a turn in the middle of a solid infill or perimeter run.  Sounds like it is going to explode.  Am i getting back feed from the printer or computer?  Is there gears in the stemper motor that are skipping.  Any ideas would be great.

Re: Extruder is knocking

sounds like the stepper is skipping... maybe the extruder drive gear(part that drives filament) is slipping against the filament also... is thee filament ground into this drive wheel(gear)?

You may need to up the temp a bit or maybe slow down the print speed... might have a partial clog, lots of possibilities with out more info.
