Blue LED turns on but probe does not deploy

## Background

I used the BTT MicroProbe v2 successfully with the SKR Mini E3 v3. When I connect the power cables, I measure 4.95V and see the probe's blue LED turn on at the same time that it does the self-test (deploy and retract three times, making three clicks.).

## Problem

Powering the probe with the Orbitool O2 toolboard it supplies 5.11V, which turns on the blue LED, but doesn't trigger self-test. The probe does not deploy or make a clicking sound.

## Next steps

Is there some meaning behind a blue LED but no self-test behavior? Or are there any steps that I should take to debug further? My best guess is that the MicroProbe is sensitive to any amount of overvoltage, but I'd love feedback on whether this is the issue.
