UM2+ Feeder Motor replacement part specs/manufacturer model

Can anyone confirm the manufacturer model number or specs for the UM2+ feeder motor?

 

I am trying to upgrade my UMO+ to use the UM2+ feeder but have found conflicting information for the length of the D-shaft of the UM2+ feeder motor. 

The Ultimaker 2+ BOm (https://github.com/Ultimaker/Ultimaker2Plus) says that the XY and feeder motors are different part numbers #1182 and #1977 respectively.

The STEP file for 1182 shows a motor with a ~17.75mm shaft and 1977 STEP file motor has a 24mm shaft. The UM2 (not plus) feeder motor seems to have a 24mm shaft. I read online that the UM2 feeder motor needs to be physically modified to fit the UM2+ feeder due to a "longer" shaft. I know that the UM2 feeder motor has a different step count then the UM2+ feeder motor. 

 

The closest manufacturer model number I've found for UM2+ feeder motor is SY42STH47-1684A but I'm not sure if that is even the right one. 

 

Does the UM2+ feeder motor actually differ from the UM2 feeder motor in shaft length?? They both seem to be 24mm long. Thanks.

    Yes, the shaft of the feeder motor is shorter on the UM2+ (if i remember right).

     

    Anyways: i think you should look for the motor assembly (motor with on-pressed gear). The spur gear is not available as a separate genuine spare part (as far as i know - cheaper replicas are a different topic).

     

    Ultimaker part number of the motor assembly is #9470

    Thanks for the info, I ended up reusing the UMO+ feeder motor with the UM2+ feeder assembly. 

    The UMO+ feeder motor is in the longer 24mm shaft length (the correct length should be ~16mm so the step file may be incorrect) so I put some M3 nuts as spacers on all four connecting screws to attach it to the custom UM2+ feeder mount https://www.youmagine.com/designs/um2-extrusion-upgrade-kit-mount-for-umo

      • 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
