Anyone know what this might be? Z stepper going bad maybe? Might do it 4 or 5 times then it's fine. No issues printing, no apparent binding.

Re: What's happening here?
Does it do the same thing without the mic6 plate? It sounds like the motor is skipping and it's immediately when trying to raise the plate after a rapid drop. I'm wondering if it's the inertia of the plate causing or exacerbating this.
Re: What's happening here?
Hard to say, next time it does it I should take the plate off. I've been using the mic6 plate for nearly a year now, never an issue before.
Re: What's happening here?
That's definitely the z stepper missing steps. It might be binding slightly or something. I think you could probably patch it by just reducing the z axis acceleration, or the speed of that move in the start script. That particular move doesn't have to be THAT fast.
Re: What's happening here?
Make sure the Z screw is clean too. Sometimes it can get a thread wrapped up in there or a buildup of old grease. (I use an old toothbrush to clean that gunk out. it can cause sticking.)

Tell us more, did you mess with the firmware?

Re: What's happening here?
Haven't touched the firmware. Everything looks clean to me. I keep it regularly maintained and cleaned.
Here's my start script.
M204 T10000 ; increase default retraction acceleration
M201 X1200 Y800 Z500 ; reduce maximum acceleration to reduce ringing
G28 ; home all axes
G1 Y50 Z0.3 F9600 ; move forward to avoid binder clips
G1 X205 Z10 ; move off platform
G1 Z0.4 ; position nozzle
G92 E0 ; zero extruder
G1 E25 F225 ; purge nozzle
G92 E0 ; zero extruder
G1 X190 Z0.1 E1.0 F1200 ; slow wipe
G1 X180 Z0.25 ; lift
