We have had a replicator 5g for two months, after using a replicator 2X regularly at our former workplace. The 2X was a workhorse. Comparatively, the 5g has *serious* problems that will cost you a huge amount of your time. Ours throws error 1024 (The smart extruder is not communicating) on every 3rd attempt to print. It fails with an extruder jam every second time, and the remaining fraction come out with horrible build quality. Often when starting a job, the extruder will park in the middle of the build platform and leak PLA while sensing the build plate position, then drag the resulting glob into the print area, screwing up the print. The self diagnostics reports an overcurrent value on one of the motor sensors, and the extruder light flickers constantly as though too much current were being drawn. We tried all the obvious things (firmware upgrade, manual calibration, scouring forums, etc.) but no dice. It doesn't help that Makerbot dissolved their official user group recently... We requested to return the printer to Makerbot Europe for a refund, but were informed that they legally have 3 attempts to fix it before they take it back. We obliged, and sent it for repair. Initially shipping was to be at our expense, but after enough angry Emails, they obliged. They returned it with a lubricated Z-axis and a 3-d printed "dust filter" and a scrap of kitchen sponge, that we're supposed to add to their product. The idea is to soak the sponge with WD40 (their suggestion) and run the PLA through it as it passes into the extruder head. This hack got us past error 1024 more frequently, but the printer is still effectively unusable and Makerbot refuses to do the right thing and accept a return. So in answer, stay away from Makerbot's latest beta product (the 5g), until their newly reorganized company figures out how to support their customers. (Hint: If you don't purchase their support plan, you'll pay $100 each time to call them for support when (not if!) your printer breaks: http://www.makerbot.com/makercare). We need to 3d print for our research, so in the meantime we've ordered an Ultimaker. The reviews look solid, the user community is active, and the thing is open source - my conclusion is that even if there are some initial growing pains, we won't be screwed the way we are now.
