I have a random behavior of U axis in KT332N since I update to 1.2.0.X.
In 1.1.X.X works great since Lightburn include U axis with kt332n but now sometimes move the U layer, sometimes not.
U layer works fine with ruida buttons or Lightburn console up/down buttons but when I send a file with a out-of-focus layer who knows.
Note: files were created initially in 1.1.X.X but modified several times in 1.2.X.X
