The temperature commands ignored (M104, M140, M109, M190) are fixed in Firmware version v1.6.1.0 (with TS v1.6.1.2): Snapmaker 2.0 Firmware Updates and Downloads
I have to state that only these 4 commands are overwritten by TS in order to have the adjustment feature. We don’t have any reason to change the behavior of original M900.
