alignment issue replacing x axis motor


Recommended Posts

Posted · alignment issue replacing x axis motor

so my x axis motor failed an ive got a replacement from robokits in new zealand n(its the same stepper motor ultimaker uses.

when i installed the motor i noticed the belt doesnt align properly, anyone know why that is? should i just put some washers on the mounting bolts to try and bring the motor into alignment?

i made sure that the gear on the rod is pushed all the way to the bearing and it still wont align properly.

    i did that, and now it is more aligned, but when i tighten everything up and slide the hot end back and forth, the belt sort of wobbles like the pulley is egg shaped or something, it rotates fairly smoothly, but you can still feel a bit of tugging as it tightens and loosens with each rotation. any thoughts?

    If was like that when you used it it might have stretch and loose it's original size. The only fix I know (without mods) it's a new belt.

    Did you try to invert also the pulley on the shaft btw?

    i only inverted the pulley on the motor. ive tried moving the pulley back and forth along the motor shaft a little bit to try and align it better but it still happens. ive tried loosening the pulley on the x axis shaft to help align it and it hasnt helped. i wasnt having this problem before i replaced the motor either.

      • 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.
