Skill builder - CNC router

I made a lot of mistakes this week.

​The first time, errors appeared in Mastercam because I drew redundant lines and overlapping line in the Vectorworks.

Then, I did not put the drawing at its original point so that the router did not start where it was supposed to be.

Then again, I made the drill bits too loose and it fell off a little bit and messed up again.

It works well finally.
