Hello,
I am Trish from Towson University, we are currently trying to get our first 3D printer, the Makerbot Cupcake CNC with Mk4 Plastruder up and running. However; we are having a few issues.
We got the machine tightened and ready for its first test print only to have it end up in a total flop. First off, the print was not recognizable, it was pretty much a blob of black goo, it never seemed to really raise above about 3mm and did not seem to follow the shape of the print what-so-ever. We generated the code in the newest version of ReplicatorG with the integrated skeinforge and selected the proper driver.
Shortly after this print, the machine was moved and lost the feed of the filament. We removed the filament to find notches had been cut into the plastic and the wheel was cogged. We removed the extra filament and attempted to re-feed the machine. It worked again until it was moved. Should it have notches in the filament? It seems to extrude fine when it does leave the notches but should it and should it stop feeding if it is moved?
Another issue we had shortly after we got it to start feeding again is the belt on the z-axis jumped and began to grind. We killed the build to find that bolt which had been tightened previous had worked itself complete off on the left side and the bearing were hovering over their housings. We thought about securing them with some type of adhesive, but I am not sure that is the proper course. Has anyone experienced this before?
Thanks for any suggestions and help in this situation.
Sincerely,
Trish
