who knows these things real well. Cannot get it to print

[printbus]

... Techout isn't ready to divorce his printer and he wants some counseling.

A degree of counseling was already provided to Tachout in his thread on the same issue from two weeks ago What am I doing wrong Extruder eating fillament.

Tachout - in that thread, you reported the printer was doing fine on a file sliced previously, and here you're saying a prior file doesn't print. Are these the same files or different ones? I previously provided a link to a composite description of everything people have suggested as causes to their extrusion stopping. As those descriptions suggest, the hobbed bolt carving into the filament can be caused by any of a number of things. Can you elaborate on what you have investigated and what you haven't?
