UM2+ with Bondtech DDG Feeder - issues loading filament


Recommended Posts

Posted (edited) · UM2+ with Bondtech DDG Feeder - issues loading filament

I today installed the Bondtech DDG Feeder in my Ultimaker 2+, installed the firmware provided on their webseite and did a factory reset afterwards.
If I load a filament through Ultimaker's menu, it gets fast forwarded in the bowden tube but it ends before entering the print head.
From there on the filaments proceeds in the bowden tube with the print speed until it finally reaches the nozzle and gets extracted. Unloading the filament causes the filament not to fully unload!
With the original feeder/firmware everything was ok. I have been using the most recent orignal Ultimaker firmware and the original factory installed bowden tube. The bowden tube is fully inserted on both ends. I have checked that.

 

I gave both firmware versions on the bondtech website a try, Ultimaker2_DDG_Firmware_20171023.hex and Ultimaker2_DDG_Firmware_20171117.hex as well as Tinker-MarlinUltimaker2plus-17.10.1.hex. I always did a factory reset afterwards.

In TinkerI've set the E-step to 311 and Loading speed to 50 mm/sec as described by Bondtech.

 

No Luck!. Filament stops far before entering the printhead, about 5-7 mm with the Bondtech Firmware, a bit more with Tinker.

I couldn't find any settings in Tinker to define the bowden length. I am not ready yet to shorten an otherwise perfect-length bowden tube.

 

Any ideas what might be wrong here and how to fix it?

 

Many thanks

Matthias

      • 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
