It is doable... But you are going to have to write your VB script to probe the tool. I hope to have time to make the scripts but it is going to be some time... But if you work on it I wil help

I did alittle vb scripting about 3 years ago.  nothing major.  just angle formulas i didnt feel like doing over and over again. What kind of vb script are we talking about?

Just to ask.  What cause noise in the line like i got on my home switches?  Bad wires?  Bad connections?  Because the wire i used for my home switches is cheap speaker wire.  i had to get the machine up and running asap so no time to get anything better.  So i just threw it in.  Any suggestions on a bitter choice for wires for homes?  also any suggestions on the best home limit switches?  i still need to get home for my Z and limits for all my axis.  And still need to wire into my estop. 

The noise is from other wires in your system... If you have power wires running along side the logic wires you can pick up noise...
