Posted · Z-Achse nach dem Homing nicht limitiert??

Hallo,

ich habe einen Ultimaker Original mit nachgerüstetem Heizbett und er hat bisher gut funktioniert. Neuerdings habe ich das Problem, das ich die Z-Achse nach dem Homing noch nach oben über move-Z in den Minus Bereich zu verstellen geht. Daraus resultiert dann das beim Drucken das Hotend in das Druckbett fährt.

Habe die Firmware schon mal neu aufgespielt und die Z-Achse unzählige male neu ausgerichtet.

Die Treiber sind auf TMC 2208 verändert worden und wie beschreiben nur die Anzahl der Schritte verdoppelt worden. Das hat aber für 20 Drucke gut funktioniert.

 

Plötzlich jetzt das Problem...

 

Wer kann helfen?

 

Viele Grüße

 

Daniel

      • 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.
