Workflow Process Question

So I am a proud new owner of the Shapeoko Pro xxl and just finished setting it up and watching videos but still have a basic workflow question.

I’m transitioning over from a hobbyist level machine where my workflow was in Carveco or Easel and GCODE using UGS for control.

I have the Pro with Bittsetter and also purchased bit zero v2. I’m confused on a basic workflow/setup with these systems. For starters, contrary to many, I use/set z zero height to spoilboard/bottom of material so my profile cuts don’t cut into spoilboard.

So I am about to just do the coaster tutorial cut, but confused on what the work process is. Home the machine, jog to set x/y zero, but where does the bit setter and z zero come into this process?

Check out for lots of good tutorial videos

You would use the BitZero to set the origin at the corner of your rectangular stock — that will set X, Y, and Z — then, if you want the origin at the bottom of the stock, reposition the BitZero and reprove for Z only.

The BitSetter will only come into play if you have multiple tools in a single file, or if you are probing w/ a probing pin, then switching to the tool — many folks who are doing work w/ a single tool will disable it.

one of the major confusions I have is the bit zero states to use the “metal dowel pin” provided. But then you have to change out the dowel for the actual bit. So I am messing with z zero but putting a new bit in and how is the machine figuring out the actual z zero after the bit/dowel swap?


If you have the BitSetter, use it to manage the tool change.

If you don’t, if need be reposition the BitZero and reprobe for only Z.

ok that’s the part i was missing. Thank you.

This does a good job helping with work flow:
