[Assembly Manual: UM2+ Upgrade kit on Ultimaker Original Plus]

The bowden tube and black snake ( braided sleeve) are connected. As the yellow wire was long enough, I also verified that the green wire was't stuck in the sleeve as there are some connectors inside the sleeve.

@amedee thanks for the tip

Here some pictures of the install.

[Assembly Manual: UM2+ Upgrade kit on Ultimaker Original Plus]

Hi Neotko,

I finally found time to install this upgrade. Works really well.

I have an UMO+ with the 2.1.4 revision PCB so I used the experimental branch of the custom firmware builder. https://bultimaker.bulles.eu/experimental/

Fans

- Fan kickstart: 200 ms (krijgt 200ms het volledige vermogen)

- Fan minimum PWM: 70 (min Fan speed 70/255)

- Fast PWM: enable

- Hot-end fan: enable

Mechanical

- Invert first Extruder (0) direction: enable

The only minor problem I had was the green wire of the Fan that was to short to connect to the board, so I extended it (the yellow was fine).

I also used the metal plate for the feeder assembly like instructed for the UM2+ upgrade. I should probably reprint the part and make it a little thinner but I measured it and the gears were engaging perfectly.

Test prints are perfect everything works fine

Thanks to you and amedee for the instructions
