Juan: I leave the red switch for detecting when the nozzle is into rest position and this red switchs with a magnet will disconnect completely the power from the board to avoid power consumptions in resting position. But of curse they dont need to solder that. Then We can solder it with some cables and test if the idea works.
Action: To remove that on the BOM.
Neal: a Position Tilt Switch would be better - then only that position through gravity will affect the device - no magnet needed
