It seems like they have some serious problems with their quality.
At least this guy is upset:
My replicator is al so unusable piece of junk.
You can,t change the nozzle of the replicator printhead??? I dont think you need to change complete, that’s insane, with the nozzle may be enough.
A nozzle may cost 10$ aprox.
I change the nozzle but nothing change. I have clicking sound on extruder. Makerbot send me new extruder, but after few prints same problem. I thing this printer is unusable. My money is go for nothing.
Search in thingiverse new extruders for e3dv6 hot end.
Someone fits in the makerbot X carriage for shure.
Ok, thanks for suggestion
Finally the prusa i3 wins xdddd, 500€ no problems xddd
