Thank you Joe,

I'm going to the shop shortly to try all this out for real since your reply adds confidence I am on the right track starting with Bleeth's help. Still open to any comments on the [ST] command. I'm thinking my table base coordinates were set up when I newly ran all the 'setup' files when I first got the machine. I want to be confident that if/when I use the ST command, I will go back to the home of 0,0 since that is where I currently start for most things.
