hi gang-

I am hoping someone here can help. I have a MakerBot 5th gen. It goes through the leveling procedure just fine, it loads filament fine, all seems good. Then when I start to print it immediately presses the nose of the extruder into the build plate and tries to print. It immediately jams. I re-level the plate (easy, requires almost no change), reload the filament (no problem, filament comes out of the end of the extruder) and try again. Same thing. When the printer tries to make that initial right to left pass, the nozzle is pressed down hard enough to make a groove in the tape and it jams. Sometimes it makes it to the first inch of the raft, not usually.

Any advice would be tremendously appreciated,

Dave
