Bondtech for UM3

[Smithy 1,146]

If I would plan to upgrade the feeders of my UM3, which one should I use?

There are 2 Bondtech upgrade kits for the UM3 available, the DDG and the QR kit with the stepper motors. 

 

Which kit makes more sense? Are the stepper motors much different than the stick UM motors? Does it make sense to change it?

Or is the DDG enough to "upgrade" the UM3.

 

I also have to say, I have currently no problems with the UM3 feeders, but just looking what could make sense to upgrade.

 

Thanks!

FWIW I just took delivery of my DDG kit last evening.  I will provide feedback as soon as I have it up and running.

 

My decision was based on my intended use and constraints on the printer.  I've had no issues with my existing feeders but would like to print abrasives and also thought the bondtec gripping might do better with difficult filaments like TPU and PETG.  That's not yet proven.

 

I looked at the QR kit but in my case, it was more invasive than I needed to achieve my improvements.

 

Now, if anyone knows a good way to recycle UM3 feeders on a UMO ?

Thanks and yes please give us some feedback after you have upgraded.

 

I think I should contact Bondtech directly, what they say about the difference between the two kits. I searched the web and forums a lot, haven't found users which have the DDG and the QR, but was not able to find a descriptive difference. Also the Bondtech website don't tell much about the difference.

 

But maybe someone else have more infos about it.....

Whats the question? , just print a bracket and mount the feeder? And if you're upgrading anyway why not also put in a UM2 head....

 

and QR vs DDG, it seems to me the QR is easier to clean vs the DDG as it's a more open design. I happily use a QR on an UM2 for a long time.

Is there a noticeable difference between the original UM stepper motors and the Bondtech ones?
