I have begun to dig into the problem after the first print failed.


It appears that the factory did not clear the nozzle after they did the test print.  I also had problems pushing the new filament down into the nozzle.

When I tried to feed the ejector, the drive wheel turned, but did not appear to be pushing filament like it should.


Plan for today is to clean the nozzle and see if I can get the drive wheel to push the filament so that it can print.


From what I have read, this appears to be a common problem so I will spend some time looking at the design to see if I can see anyway to improve the design.

Right now I am thinking of a reverse mechanism like Ben Heck used on his glue gun, but I need to get it working first.
