Blue LED turns on but probe does not deploy

[christianbundy]

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.
