Finally you can convert your UM2 / UM2+ to go with 1.75mm filament!
You have the choice to install it in the 2nd block position (UM2), or just replace your existing block. If you have a UM2+, you need a new fan shroud with 2 holes.
If you put it in the second position, you can have both setups in parallell. Then you will need to add Heater and Pt100 temp sensor to the order. You will also need a 2nd feeder, we recommend Bondtech.
