Bondtech DDG on UM2 Extended


Recommended Posts

Posted (edited) · Bondtech DDG on UM2 Extended

Hello guys, greetings.

So, I am using Tinkergnome V17.10.1 (which I believe is the latest stable version) in a UM2 extended upgraded with a Bondtech DDG (with a adaptation piece found on YouMagine). I'm having two problems:

1)Once in a while my Printer inverts all the axis out from the blue, no clues whatsoever why it is happening, I have to factory reset it, and start all over again (and dialing all the steps again);

2) I am using the stock 0,9º extruder stepper motor, and since I installed the Bondtech extruder, depending on the nozzle temp, I get heavy and frequent losing steps. I have a feeling that I was using lower temps incorrectly (for the PLA brand - Brazil, so it's unlikely you would know it). Once I step temps up it gets on track, although I was not able to notice if it is affecting the print quality (dear strings).

Any ideas?

Is it better to install a newer Tinkergnome software? 

Thank a lot in advance.

    I replaced de third party stepper motor gear for yet another, this time a metal one. For now it seems ok. I bought the DDG for a ultimaker 2. Not +. So I had to make some adaptations - a 11 teeth gear (Aliexpress although you can print one) and a spacer adaptor - which I printed.

      • 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
