UM2: "Error - Stopped: X or Y switch stuck"


Recommended Posts

Posted · UM2: "Error - Stopped: X or Y switch stuck"

So I've had my UM2 for over a week now, and am happy to say that I've had...minimal problems with it. (I've been fighting the feeder and was actually printing a better one when this issue happened.) I had a print break off the plate, so I aborted it and prepared to print again after a while. I started it, but I got nowhere as the head wouldn't home correctly. Later attempts after cycling power yielded the same result: the printhead would move along the x-axis first as it always did, hit the switch, then stops dead against the left side with the steppers locked. It doesn't even attempt to move along the y-axis. The dial starts changing colors (which is neat), and the screen displays "ERROR - STOPPED" and below that "X or Y switch stuck" (which is not) "Contact: support@ultimaker.com"

I've cycled power several times to the same effect; when the power is off, I've moved the head and everything still feels smooth. The switches look fine and are definitely not "stuck" in that I can depress them easily with the appropriate click. Any ideas?

    Yes, and to no avail.


    The firmware just reads a value from a pin on the electronics board and it seems that this always gives the signal: "endstop is pressed".

    You can check the cables and connectors for yourself (with the help of the assembly manual)

    Or just do what the displayed message recommends: contact support...

    Sorry - no better news...

    Ah! Finally. I did some work to retension my feeder not too long ago. So it turned out that the wire I had running to my Y endstop got caught between the feeder stepper motor and the printer's frame, crushing it. The insulation got pressed flat, and the metal of the frame and stepper motor caused it to short. I just covered the wires in kapton tape and reran them. All is well! ^^

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!
          • Thanks

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
