"No trigger on z after full movement" with position_min: -100

Most probably your probe is constantly misfiring.

In your video a blue led is blinking in your extruder head - it’s your probe triggering.

During Homing sequence - it’s immediately stopped because probe should be silent until it will sense the bed, then it should retry few times (in expected range) - if something goes wrong - you will get that error, or some other error.

It can be a probe itself, it can be a broken probe wire, it can be additional weight on your toolhead, it can be jerky Z movements, etc …

Confirmation of my words are present in your log, when you was playing with settings - few times there was following error registered.

Probe triggered prior to movement
