    CubePro 2 Service-Pittsburgh, PA

    Hello. Our school has a CubePro 2 printer. It's a backup printer at this point as we've added a FabPro 1000. On the CubePro 2, the filament has come out of one of the nozzles and that nozzle is loose. It appears as though a screw that holds the nozzle in place has fallen out. But, I can't find it in the printer.

    The company that sold us the 3D printer will no longer do service on it. They keep referring me to 3D Systems. But, 3D Systems won't return any of my emails.

    I'm looking for a service company in the Pittsburgh, PA area to take a look at it. I'm not exactly sure what is missing and what needs replaced/fixed. I'm also looking for a replacement glass bed for the printer as one nozzle still works and our current glass bed is pretty beat up. As a result, jobs keep failing. 3D Systems no longer sells the glass bed and I can't find anything on Amazon or eBay.

    Any help/thoughts would be greatly appreciated. Thanks.

    Hey jammincomedy. Welcome to the forum. There are two ways the nozzle can remain loose, a screw that clamps the tube in the housing and the one holding the housing to the frame. I would recommend a 3D printer enthusiast have a look and see what they can see. You can certainly show pictures here and we can see if this is a big deal or not. probably not. Someone probably did a maintenance routine and left things undone.

    As to the glass, it is best to do a good cleaning and add LokBuild as a build surface. That will restore the glass.

    Please let us know what you find. There are a lot of maintenance videos on YouTube that detail many of the routine efforts these printers require.

    Thanks for the reply. I'll look into the LokBuild solution. I have attached a picture of the issue. You can see the filament hanging out the back of the nozzle. You might also be able to see that the left nozzle is hanging down a bit. It's basically just hanging there and bends back and forth when touched. So, I'm guessing that's where the screw is missing.

    That nozzle on the left looks bent. Which one is loose?

    It’s the left nozzle that is loose.

    I must admit I don't have the structure in mind well enough to see what I am looking at.



    According to the video, the nozzle is one piece and somehow yours has separated. The one-piece nozzle should remove with the single screw from the filament driver as shown in the video.

    Replacement parts are highly dependent on eBay. Poor selection at that. Easiest consideration is to make the Duo a Mono. But you really will need to get familiar with this machine. It has very little going for it in the way of support.

    Yep, the one piece aluminum body is broken. I've seen that occur if the bed isn't seated fully or someone fires off a new print while the last print job is still on the plate.

    If I had a spare nozzle handy, I would gladly donate it but I gave my last one away last summer.

    I just confirmed that I have an extra print bed that I can donate to you. Saving a CubePro from the dump and supporting a STEM program is a win/win. Please PM me.

    Not sure how to PM you. I honestly just saw this. I’d be interested in that print bed if you still have it. Jesse Saunders, Avella Jr./Sr. High, 1000 Avella Road, Avella, PA 15312. Thanks.

    So, I ended up purchasing an entirely new extruder for the CubePro 2. I got out the 4 screws that hold the actual extruder in place. But, what size is the screwdriver bit that is needed to take out the screws on the housing above where the extruder sits so that I can pull the old extruder up and put and put in the new one? Thanks again.

    Sorry but the print bed is gone. Cleaning up the old bed and putting lokbuild over it is a great option. Its a great solution.

    The only 2 tools needed for the print head assembly are the 2.5mm allen and torx 10. The torx bit is only used on the bolt that secures the print head to the feed assembly (bottom back). The bolt is accessible easily for printjets 1 and 3 but the middle one (printjet 2) requires the lifting of the board.

    Detailed instructions are still available on 3dsystems web site. They are very helpful.

    CubePro 2-new extruder-put back together

    Hello again. I ended up purchasing a brand new extruder for our CubePro 2 and was able to get it into the location on the printer where it goes. However, I'm having trouble getting the rest of the pieces back together. Are there any tutorials on reattaching the wires and filament tubes? In the attached picture, I'm not sure what pins to plug the two wire ends into. They don't seem to want to slide on the six and five-pin sections on the board. I'm also a bit hazy on where all of the screws need to fit.

    A picture of the board setup related to the extruder and wires would also be welcome. I should have taken a picture of the setup before I took it apart. The directions are confusing.

    Lastly, if anybody is getting rid of or selling a print bed for this printer, I'd be interested. Thanks again.
