Well, I had to clean out the extruder last night. I completely forgot about the camera; I was setting up to print heart gears for my sweetie, and just wanted to get back to printing.

I would recommend that you remove the extruders from their carriage before you do much work. It makes re-assembly easier, since you can stack up the plastic spacers on a vertical axis, that way.

It was not difficult, once I figured out where everything was and how to get to the guts of the matter.

Thanks, Geoff, for pointing out the relevant threads.

Cheers,

John
