Good methods to clean extruder gear (hobbed) from filament pieces?
I'm using a CraftBot original to print PLA, but some of the filament has become stuck in the teeth of the extruder gear on its way into the hot end. I'm having issues with the gear becoming stuck and "clicking" instead of turning, and I suspect it is because of the clogged teeth. I haven't changed materials in a long time. I've cleared several print head clogs, but each time the gear gets back around to the one spot, it seems to get stuck again.
Are there any good ways to clean this gear? I was thinking of putting it in a toaster oven and trying to melt the PLA off it, ideally without setting my house on fire in the process. Anyone have better ideas?
