Anybody out there using a Mk7 extruder?
I have mBot Mk 7
http://www.mbot3d.com/collections/toolh ... p-printers

The mBot Mk 7 is different than the makerbot design, it uses an idler wheel to keep filiment against gear instead of plunger.
My mBot Mk 7 very inconsistent extruding and clicking loudly.

any suggestions
