Sounds like a clog.

I have been doing fine with prints up until now. All of a sudden, I hear clicking which I assume is coming from the hobble gear skipping on the filament. The printer, while this was going on, was under-extruding. (I have seen this in the past with my other 3d printers during over-extrusion when it just can't push the filament out quickly enough.) I was able to extract the filament and run the extruder without filament. No clicking. When I put the filament back in and just try to extrude some into the air, I see it is under-extruding and clicking again.

Thoughts prior to a disassemble?

Thanks!

Update: I pulled the motor, heat sink, and fan off. They look fine. My guess is there is a clog further downstream.
