magnetic sensor - wiring

[PetrKroupa]

I found that if the wiring to the magnetic sensor is faulty, it is a big problem to find a fault. Of course, if bad is connected, it's easy (M591 D0). However, if the wire is broken and the connection is broken randomly, the printing will pause the "little movement" but you will no longer know that it was because the sensor did not work at all for a while. I spent a few days mechanically tuning the sensor and then accidentally noticed that it reset randomly. The green LED status flashes 3 times and than continues to run.

It's such an idea but adding some distinction between these two states would be nice.

Something like "no data from sensor" and "little movement".

@petrkroupa thanks for the suggestion. I have moved this into the firmware wishlist section.
