Description
In order to use a UM2 printhead on a Ultimaker Original+ (UMO+), the top part of the printhead needs to be rotated 90 degrees. I designed a dual extruder version, based on the original part (see github, UM2, step files).
Also included is a modified bottom part, which enables to use a thicker fan (10mm) and still guide cables through the printhead. I used a Sunon MC25100V2-000U-A99 fan which has a good airflow while being very silent.
Works like a charm, see video

Marco3D commented agoHi,
1) for the heater and sensor I did not adjust the firmware. Btw I replaced the UM2 nozzle block by an olson block with a 25 W heater, so you're situation could be different. If you notice a temperature overshoot during heating up, or during printing, you should perform an autotune of the PID values. That should be sufficient for the temperature control.
2) Note: there is also a dependency on the fans and the control board. The UM2 fans only work from a certain PWM value and need a kickstart. If you do not update the firmware it will only start spinning at full PWM (see https://bultimaker.bulles.eu for firmware). The heater fan in my case is on by default. However, depending on the version of your control board it is being switched on/off at a certain nozzle temperature. In that case you will probably need a custom firmware.

did you change some firmware settings to get UM2 heater sensor and heater cartridge working in an espected range?
