The Jyuers Firmware is stated to be for the Ender 3V2 only with the 4.2.2 or4.2.7 motherboards.
If someone has a different printer, like a late model Ender 3, with the 4.2.2 MB can the Jyers firmware be loaded onto it??? It wouldn’t have the upgraded display but that really isn’t necessary to run the Jyuers Upgrade. The 3 and the 3V2 with the same MB are similar machines where it counts…
