Hardened core for U3

[pbenek 0]

Hi,

I use Ultimaker 3. I need to print with filament that requires hardened nozzle. Is it possible to adopt print core CC to U3? Or maybe change nozzle in core AA?

You can use the CC core also on the UM3, you will just get a warning in Cura because the feeder gears are not hardened. So beware of that, that when you print with abrasive materials that you will damage and wear out our feeder.

 

Another option is to use the 3DSolex Core, there you are able to change the nozzle to whatever you want.

The 3dsolex core with the "everlast" nozzles is great but again you want to harden the feeder.  The best and cheapest option is to get the bondtech DDG feeders for the UM3.  Unfortunately you kind of have to update both feeders because the UM3 firmware doesn't allow a different steps/mm value for the 2 extruders.  Although you could do a hack where you adjust the flow on just the left feeder.
