When my cut is complete, Easel has the Park command shown, but will not allow me to park the spindle. It says I must be logged in to Easel, which I am. Any suggestions?
Just a hunch, but try to log out and then back in 
You could run a very short test cut in air and test the park command again.
Thanks. I tried that but I still see the same message. Also, it says that I need 6" clearance behind or in front of the work piece, which I do so I am not sure what that means. I have the work about an inch out from 0,0, so there is plenty of parking space.
