Components Detection for extra high Voltages

High voltage for probes¶ One common problem when using inductive or capactive probes is the voltage which they are powered at. These probes are usually connected to the Z endstop, which is powered directly by the microcontroller. This means 5V or 3.3V, but these probes are not designed for such low voltages.
