 24V DC is used to supply myCNC-ET6 control board. Power consumption depends on external peripherals you have connected to open collector outputs and +12V/+5V outputs. Normally power supply 24V/2A should be enough to power up the controller based kit with single board computer and 15'​6"​ TFT screen. However, step-down converters on the ET6 board consume start current about 1.5A and 24V/1A power supply might be not enough to supply the single ET6 board. 24V DC is used to supply myCNC-ET6 control board.
