Dual Nozzle Printing issues

Posted · Dual Nozzle Printing issues

Hi 3DP folks, I'm a 3DP lover and likes cura soo much.

For dual extruder case, i need some suggestions regarding.


"Whenever nozzle switching happens, The tool head is coming to the bed center where part is located, passing through the print and then going to the prime tower, this time gap is creating to ooze more in ideal time, i have used first layer temp, default printing temp, nozzle switch temp and standby temp all equal and as low as 190 degree.


My question is..,

1) How to bring the hot end directly to prime tower with out passing through the Printing part?"


2) Is there any G code over ride or expression variable to enable start G code to go to prime tower directly. I have tried in Start G code extruder 1 with G01 X200 Y200(same location of prime tower) but still again nozzle behavior is same like passing through the print then going to prime tower address and coming back with ooze.


3) Finally i tried with Ooze shield, one thing noticed is whenever nozzle switch is there, the nozzle directly comes into part, without printing ooze shield which i think is not correct, if the path is along ooze shield and then it is coming into path then only ooze can be controlled.


Request not to suggest with both Ooze shield and prime tower which will take more time, also i tried with nozzle wiping using brass brush making a parking location, even it hasn't worked out.


Please have a look into it to resolve, will be eagerly waiting for your reply.

    What printer do you have, and how did you add it to Cura? Did you use the "Custom FFF Printer" option, or a predefined printer?

    Can you save a project (File -> Save As...), upload it somewhere and post a link here so that we can see what settings you use?

      • 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
