The Z axis is stuck or the limit switch is broken - ER16

Posted · The Z axis is stuck or the limit switch is broken - ER16

Hello, I have a problem with the Z axis, I am using the ultimaker 3 printer. I tried to follow the recommendations given on the ultimaker.com/ER16 link without success. moreover, i can actuate the limit switch manually, and this proves that the switch is working correctly and that there is no object at the bottom of the plate blocking the descent of the plate. But when launching the printer I get the same ER / 16 error message, can someone help me?

    If you go to System -> Maintenance -> Diagnostics -> Limit switches, does the indicator for the Z-switch get an "X" in it? And does it go away when you manually grab the platform and pull it up?


    If not, you're either dealing with a broken switch, a bad solder joint of the wires attached to the switch itself or a bad connection to the mainboard. If you have access to a multimeter you can probe the connector for continuity and see if it gets continuity when the switch is pressed, that would verify that the switch is physically ok or not.

        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.
