    One more question the stock fw seams to be diffrent when looking at the fw version on the display it say Version_3.3.0 Marsh 15 2018. As there is only one release from UM2.1-Firmware and its called 15.11. Is there a way to get the orignal fw back if i add the one from github ? and what is the diffrens ?

    Just because there has not been a tagged release does not mean there are no newer changes. Here are the changes between that tag (15.11) and the default branch:



    The Version_3.3.0 March 15 2018 version is probably based on this commit:



    Changes from that commit to the latest state of the default branch:



    Default firmwares for the UMO(+) and UM2(+) families are included as .hex files in Cura. See the resources/firmware folder.
