I'm confused about voltage and was hoping someone could steer me in the right direction.
I have an Arduino Mega 2560 that was configured by Anycubic for a deltabot printer.
When I test the leads for the extruder's hot-end my multimeter says 12.65v are available (which I need for a newer hot-end). However, everything I read about the Mega 2560's specs says the board operates at 5v.
