The Quick Access LED Button (#5 in the User's Manual) is between USB and microSD card slot.

• Pressing the button will automatically start printing the file named auto00.g (formerly cat.gcode) on the microSD card. The LED will blink green three times then remain illuminated.
• Pressing the button while printing will pause, pressing again will resume. If illuminated, the LED will go off when pausing and will be green when resuming. (The pause action may take 5 to 10 seconds to occur)
• Pressing and holding the button for 4 seconds while printing will cancel the job. If illuminated, the LED will go off when canceling.
• Pressing and holding the button for 4 seconds while in idle state will initialize Wi-Fi smart config for use with the WiFi Connect mobile apps. The LED will blink blue 3 times then go off but the smart config will still remain active.
• When any of one of the three bed switches are activated/pressed down, the LED will be red.
