TouchScreen flipped on diagonal axis


I have a Raspberry Pi 3 with a Kuman TFT touchscreen. AstroPrint is flipped on a diagonal axis. The upper right and the lower left are correct but the upper left and the lower right are swapped. I assume that I need to modify the 99-calibration.conf file, but I’m not sure what to put in.


Hi Joe,

This screen is not supported. Not only the axis is flipped but your color are likely inverted. Please take a look at this to see which screen our AstroBox Touch supports:


I think that one person here: Rotate Astrobox Touch display
Had also the same screen and in the end he was able to rotate it correctly.


present, I actually succeeded


I have succeeded with your own screen, follow the directions here: Rotate Astrobox Touch display
