Hello everyone!
I’m having a problem with my REPLICATOR Z18. The stepper motor that attaches the smart extruder is not working very well, any suggestions?

have you tried contacting makerbot support ?
yes, i’m waiting for their answer… 
It seems the connector cable from Stepper and electronic is not well connected. That sound happens when one wire is not well connected. I think 
Next time buy 3d printer so you can build and learn from him is more cheap I told this for my experience
It sounds like something loose inside (maybe the drive gear) is touching with another part. What about opening it and having a look inside?
