@Julien you are THE Man!
Thank you sooooo much for this guide, it is just what I was looking for!
I made all the settings and the macros, tomorrow I’ll test everything.
I needed a macro for resetting only the Z height, I followed this suggestion
hope this will work.
Now I only need to make few very simple macros to rise the tool above the sucking boot, to place the head at the top center of the shapeoko, etc
