The calibration process is completely automatic. It will inform you of its progress and current task. The whole procedure only takes a few minutes.
The process starts by warming up the LED panel to a stable temperature, before calibrating the different areas of the display.
You will be provided with an estimate on how much time is remaining of each part. Feel free to leave the printer and get some gummy bears. We are almost done:)
Applying the calibration results
