And I’m going to be offline for a bit… so I won’t be responding

I had to reduce it to ~500 to get the alert to stop popping up.

Where the alarm is popping (based upon review of the video), there is no x or y movement being made, only z axis being raised… and z axis is not monitored as part of the “sled not keeping up” alarm. I think he has “residual” x,y error that is being caught when the zaxis move is being made.
Did anyone ever answer the original question? If the bit is extended how do you get it to retract?
Generally when we don’t hear anything back it means one of the suggestions worked, but there really isn’t any way to know which one it was 
You can use the buttons to move the z-axis in or out manually, where exactly those buttons are will depend on what software you are using, but generally you want to look for a z-axis button over on the right.
Honestly, I’m not sure. The raise button was physically moving the sled…and then it wasn’t and was raising the bit. The CNC gods smiled on me!
