Screw hardware for UM3


Recommended Posts

Posted · Screw hardware for UM3

I want to build a door for my UM3 and I'm trying to find the screw size. I found posts for the UM2+ saying that they're M3 screws. Anyone know if they are the same for the UM3? Anyone know the screw lengths for the front panels? (so I know how much longer to get to affix my door).

Anything I should be aware of before I go removing screws? (I'm gonna do it one at a time, carefully)

 

99.71% (roughly) of the screws on the UMO and UM2 are 3mm standard pitch also known as M3 screws. And they are all button head with the 2mm hex screwdriver style.

    It's an M3 screw, but I echo what ultijaran said. I don't recommend unscrewing the frame panels of your printer...ever. Short of having to replace one of them, everything you ever need to access can be accessed without removing them. Removing any of the frame panels will generally throw your XY axis out of alignment and it will need to be recalibrated. I would definitely go with a door that pops into place, or hangs on a hook over the top.

    Thanks for the help. I ended up unscrewing the screws from the side of the frame, but only two at a time, so I don't think I've messed with the rigidity of the frame... (I didn't remove any panels!).

    I'll post pictures of it when i'm done, but basically I created a barral hinge and mounted the hinge to the frame by buying 20mm M3 screws (manually tightened the screws as to not over tighten). I connected via the upper two screws for one hinge and the lower two screws for the lower hinge. So far it's working out well.

    I made the door with 1/2" acrylic, which I realized afterwards was overkill, but it looks really nice. I mounted the hinges in a way that the acrylic closes flush with the front panel.

    Next step is the upper enclosure (1/4" acrylic for this one...)

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
         
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
         
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
