After replacing Ultimaker main board the Z-axis goes too far.

Posted · After replacing Ultimaker main board the Z-axis goes too far.

Hello,

I replaced the main board of my ultimaker 2+ because it was broken. 
When I turn it on, it starts initializing. The Z-axis moves all the way to the homing switch and moves up again but then it doesn't stop and crashes into the nozzle.
My gut feeling says it might be a jumper setting on the board somewhere since the board is compatible with all the Ultimaker 2 and 2+ printers, including the Extended versions.

Now, on the board I see something called EXT/IO. Might that be it?

By the way, the new board is the 2.1.4 version (the photo is the old board).

Does anyone know?

    if it raises up too far you likely have "extended" firmware installed which would send the bed up higher than expected on a non-extended.

    You need to reflash the firmware https://support.ultimaker.com/s/article/1667337917778

    Also no there is no jumper setting that controls this, its all firmware side.
