Hy SandervG,
when i see the rest of the UM spare part cost, i think a new one is too expensive for me.
Chri
It should only be a few Euros, you could always ask for some information. But feel free to give it a try via this way first 
I would recommend you try a search on aliexpress.com for "Ultimaker 2 knurled wheel" shipping is usually free - it just takes a while to arrive.
I have bought from there before, quality seemed OK but I can not remember the seller's name
good luck

The price including 19% VAT has indeed two digits in Germany and if you add some shipping charge the first digit is probably not a "1"... 
Depending on how urgently such a part is needed, it's still better than waiting for weeks for a cheaper part to arrive from China.
@chrii: In case you are using a Robert feeder, you may also want to consider replacing the knurled UM part by an MK7.
Edited by Guestthanks for your answers.
indeed i`m using a Roberts Feeder .
i`m not in hurry, but i also don`t want to order in china when possible.
i made a short-bowden mod (20cm) on my UM2 as a preparation to upgrade it to dual extrusion. (the same setup mirrored)
the Problem is i can`t remove the wheel from my original stepper driver, its mounted too tight, therefor i just want to use the same wheel on the second extruder.
As i`m also switching to 1.75mm filament the same time there should not be a problem with the strengh of the stepper anyways.

Edited by GuestJust realized I misunderstood and I was under the impression you were talking about a different part all the time, I thought you were asking for the rotating knob for some reason.. @dim3nsioneer's estimation is a bit cryptic but probably more accurate.

Hey @chrii, I have a spare one and you can have it. PM me for details.
As i`m also switching to 1.75mm filament the same time there should not be a problem with the strengh of the stepper anyways.
Please be aware that the Ultimaker knurled wheel probably isn't the best solution for 1.75mm Filament!

Hy @cjs, can you explain a little bit more in detail why ?
Chri
Edited by GuestI guess that's because the distance from the ball bearing to the knurled wheel is too big for the thinner filament. However I tested it with my UM2+ once and it worked fine. You could increase the feeder pressure with the lever on the side.

In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!-

Here it is. The new UltiMaker S7
MariMakes posted a topic in Official news,
The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
So what’s new?
The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.
The UltiMaker S7 also includes quality of life improvements:
Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more
Curious to see the S7 in action?
We’re hosting a free tech demo on February 7.
It will be live and you can ask any questions to our CTO, Miguel Calvo.

Cura Alpha With New Tree Support 🎄
MariMakes posted a topic in Ultimaker Cura,
Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.-

Hi Chri, did you also get in touch with your reseller to see if they could help you out?
