UM 2+ Bondtech extruder upgrade.

Anyone have any experience with the Bondtech extruder upgrade for the UM 2+ sold by Matterhackers?

I sell that also - I assume you mean the DDG.  The "plus" feeder that comes with the UM2+ is excellent.  Really really top notch.  However it is not rated for highly abrasive materials (carbon fill, glowfill, glassfill).  So I only recommend you upgrade if you plan to print with those or if you already wrecked your feeder with CF filament.

 

I know we drool over shiny things but in this case I think you will be happier with the "plus" feeder.

 

I sell the feeder also (thegr5store.com) but don't want to encourage you to buy it from me as my assistant just flew off to Europe for the holidays and would rather not sell anything until Tuesday.  🙂

Actually it is the Bondtech QR model not the DDG. Any information about the QR in the UM 2+?

Don't do the QR on the UM2+.  It's twice as expensive and not as good.  The DDG is much easier to install - it drops right in.

Thanks for the info.

I don't agree, I prefer the QR as it's easier to clean the gears. I run one on an Ultimaker2 for years and it just works. Would recommend it.

+1 for the QR, have one on the UM2Go and it works great!

QR is designed for UM2 series (um2go um2ext).  DDG is designed for the UM2+ series.

 

I am out of the habit of choosing "change filament" in the UM2 menu.  Instead I just slide the filament in and out.  You can't do that quickly with the QR.  That's one thing I don't like about the QR.  Also the QR sticks out a lot in the back of the printer and especially if you move the printer often it can get in the way (hit into doorways for example).

 

But both feeders are excellent.  I have the QR on my UM2.

 

But again, the feeder that comes with the UM2+ is quite excellent.  It can push very very hard on the filament (about 15-20 pounds).  It has a nice lever that you can slide the "wedgebot" (look it up on youmagine) under to insert and remove filament.

Thanks. Based on the several replies I will stay with the original UM 2+ extruder.
