    Posted · Edited by frankie_um3

    Suddnely my both bondtech QR extruders doesn't work any more after an update, indeed the filament does not come out at all .. it just makes the skirt and then goes to extreme under-extrusion .. almost nothing .. before they were very perfect ..!! it is as if the steps x mm did not work .. there is under extrusion .. I checked via putty and everything seems to be ok ... firmware ultimaker 3 5.3.0.20211003

    I think these lines are from a different documentation.

    There's a separate installation guide for the UM3:

    https://support.bondtech.se/Guide/03.+QR+for+Ultimaker+3/14?lang=en

     

    But...

    The "QR Ultimaker 3 Kit" comes with its own stepper motors, there should be no need to change the rotation direction?

    If you use a different setup... the direction of stepper motors can usually be changed by swapping one pair of the four cables.
