UM2+ Firmware

[Dreamss 2]

Hi i am looking to upgrade my UM2+ with a bondtech extruder, in the instruction thy reference the Ultimaker2Marlin as a base but i saw in this thread that some one had trouble and was referenced to this UM2.1-Firmware. What is the diffrence ? And what version is the correct one ?

Ultimaker2Marlin is for the Ultimaker 2, UM2.1-Firmware is for the Ultimaker 2+.

Hi

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:

https://github.com/Ultimaker/UM2.1-Firmware/compare/15.11...UM2.1_JarJar

 

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

https://github.com/Ultimaker/UM2.1-Firmware/tree/34672d2

 

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

https://github.com/Ultimaker/UM2.1-Firmware/compare/34672d2...UM2.1_JarJar

 

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