Hey Josh You are a victim of the the dreaded “False Probe”. It’s purely a mechanical thing.

The ArcDroid probes by sensing slack in the Z cable. So if anything causes the torch to Hang up prematurely it will cause it to probe higher than expected.  
So make sure your Z slides are Clean and lightly lubricated.  
Make sure your torch cables are well supported and that they are not causing undue torque on the Z slides.  
And don’t zip tie or otherwise attach anything to the Z cable.

You can also adjust your Head with the dovetail on the front to make sure you are operating in the upper half of the Z travel this will maximize the spring pressure and reduce likelihood of false probes

I also recommend you make sure your torch is mounted by the plastic part of your torch not the ceramic cup this will reduce torque moment on the Z slides and ensure your torch is protruding well.
