The AC adapter theoretically offers 120W, but it's safer to assume no more than 90W (¾ of the rated output). This will be used to drive our heating elements and fans. The Arduino itself is powered off the AMS circuit. Leaving aside peripherals, it ought not draw more than ~~500~~ mA, even when transmitting on wireless. This ought be safe, and is less than our fans were previously drawing from the AMS. Remember, Bambu doesn't guarantee any slack on the AMS circuit, and expressly instructs you not to draw from it.

The Arduino itself is powered off the AMS circuit. Leaving aside peripherals, it ought not draw more than 125 mA, even when transmitting on wireless. This ought be safe, and is less than our fans were previously drawing from the AMS. Remember, Bambu doesn't guarantee any slack on the AMS circuit, and expressly instructs you not to draw from it.

The temperature switch is a final guard against a failure in power control; it will open (disabling the heater) at 60C, the maximum temperature we want in the chamber. The Arduino enables the heater when either:
