OK, first dumb question, how do I now add an avatar?

virtual novice at this CNC lark, although I did a little bit of lathe work 30 years ago when programming was via machine code. All forgotten.

More recently worked with a company that put a cnc router in. They cut some stuff for me that I'd designed on autocad 2D

Investigating building a CNC router table for a work application, so next stop will be that section.
