Haha sounds like the story of my life! I have worked in IT since 2003 and currently run my own business so I totally understand. If there is anything I can do to help on my end I would be glad to where I can.
When it comes to this CNC stuff I am still a total noob. What I was trying to do is cut out a small image like this photo shows
The only problem is I wanted the cutouts to be inside a 140mm x 140mm square so naturally, I would need to use the smallest bit I have. But I will be patient as I am getting comfortable enough in using the larger bits in the sheet metal with my coated #102-Z and #201-Z.
