UM3 drive gear/wheel...

Recommended Posts

Posted · UM3 drive gear/wheel...

Hi all,


I am getting some issues with my UM3, mostly relating to an under extrusion and increased frequency of jams and grinding in the feeder.

After ruling out the typical issues, and double checking the basic setup,  I had a closer look inside my feeders.
They both look like the knurling on the drive wheels/gears has worn away a little. So I increased the tension on my feeders and it helped my problems.


So my question is, is it possible to buy replacement drive wheels for the UM3? I can only find them for the Ultimaker Original.

I know I could upgrade to BondTech or similar, but would prefer to just fix what is already there, and likely to be a much cheaper option..


Any help appreciated.

    Hi Rich,


    According to the BOM for UM3, the name of this unit is; "Grip axis" and P/N is; 1960-1.

    Best place to find this item is your UM dealer in your country, I'll think.

    If there is starting to be "much" play between this shaft and the (plastic) gear wheel you may consider changing this gear wheel as well.


    Good luck.

      • 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
