Can anyone confirm the correct feeder stepper motor for the UM2. I have a failed stepper motor, so i removed the original which had the following part number on it

SY42STH47-1684AW

I was unable to get this part number, but found the following part number from a company called Zapp

SY42STH47-1684A

I got one of these and replaced the old one.

The motor now works, but runs very fast, I would guess at twice the speed.

Does anybody know whats happened, have a replaced with an incorrect part? Why would the motor runs so fast.

Any advice appreciated.

    Your new motor is 200 steps/rev, the um2 feeder motor is 400/ step/revolution

    You would need to change the esteps to half your current amount

    Google on this forum (search uses google) change estep um2

    Mind that in that post the estep number isn't the one you need, I don't have the um2 esteps at hand, but I think you get the idea?

      • 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.
