	When the 3DTouch is first powered up it does a self test – Starting with the pin up it them goes down/up 3 times and ends up the the LED on solid. Continuous flashing means that there is an obstruction or fault.

	The ~~BLTouch~~ acts on the following gcode that can be used manually to diagnose faults etc but you don’t need to normally worry about them.		The 3DTouch acts on the following gcode that can be used manually to diagnose faults etc but you don’t need to normally worry about them.

	Alarm – The 3DTouch can sense when something is wrong and then goes into alarm mode which is continuous flashing. Alarm can be triggered like an obstruction that stops the pin going up and down freely, it could be dirt etc.		Alarm – The 3DTouch can sense when something is wrong and then goes into alarm mode which is continuous flashing.

	Providing the firmware is correctly configured, the sensor responds to the same codes as any other sensor eg inductive, capacitive or IR. The Start Code in you slicer should contain the sequence G28 followed by G29 to do the auto bed levelling.
