alternative way to start a touch calibration?

[feldfiber]

Hi,

we bought a couple duets and 4,3" displays and on one the triggerpoint is off, but i cant get to the touch calibration because the calibration shifted up so much that the lowest position on the touchscreen opens the macro page.

is there maybe a gcode command to simulate a touchscreen touch?

thanks for your help!

If it's the version 3.0 PanelDue board, then the only way I can think of is to flash it with the wrong size firmware (e.g. the 5" firmware), start it up (which will cause it to delete the touch calibration when it detects the screen size change), then flash it with the correct firmware.
