I have come to my whits end on this printer. Customer support has been quite helpful, but I cannot get this thing to print.

I got a new extruder assembaly from them, and it is solid and seems to be able to keep ok tension. however I can only get about 2 inches of filament to run thru before it begins to chew up the filament and just stops extruding completely and thats where it ends. The hot end is not clogged, and if I clear it, snap off the mangled filament, and feed it back in. It does the same just extrudes a small amount of filament and just stops. The gantry sags and is sitting almost a half inch low on the right side.

I have begun the return process on amazon where I purchased the unit and have emailed customer support letting them know I am going to want a refund.
