Cura prime tower wipe capability and UM3 wipe behavior


Recommended Posts

Posted (edited) · Cura prime tower wipe capability and UM3 wipe behavior

Hi, Does Cura have the capability to raise the bed to the inactive nozzle height after printing the active nozzle layer on the prime tower and before the horizonal wipe movement? If it could, this may also eliminate the need for an ooze shield because the ooze would be wiped into the prime tower before the printhead moves back to the print. 


I am trying to tune a printer definition for the Ultimaker DXU modification that has offset switching nozzles. The inactive nozzle is moved 2mm higher than the active nozzle to prevent oozing. Right now when the prime tower is created, the printer does a wipe horizontally to catch oozing from the inactive nozzle after extruding the current layer of the prime tower from the active nozzle.


This works for printers with fixed dual nozzles that have no ability to raise the inactive nozzle as the inactive nozzle is already on the same Z height as the prime tower and gets wiped as it travels over the prime tower wall. 

I am currently using M218 on Marlin to handle the hotend offset and was wondering how the Ultimaker 3 handles wiping its raised inactive nozzle.


I couldn't find any sign of Z offset settings for Cura prime tower nor anything on the printer definition page. I found a machine_nozzle_head_distance on the um3 extruder definition file which has no explanation in the main fdmextruder definition. 


Does anyone know if Cura can adjust Z for the prime tower or what machine_nozzle_head_distance  does? Thanks.

      • 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.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
