Just what I was thinking.

A lot, if not most, of the 'hobby' CAM programs tend to do almost everything with G0,1,3 anyway presumably because there aren't many cases where it makes a difference. For instance V-carve doesn't even use G81 to drill, just uses G1 and G0.

Just yesterday I was chamfering some large rectangular aluminium parts, but due to the parts having taken so long to cut and the MDF bed the chamfers were uneven. Easily solved by measuring the actual width of the chamfer in the 4 corners and adding Z moves to those points to make the tool move on an inclined plane to compensate for the bed...didn't need any fancy codes, just a bit of common sense. Look them up if/when you need them.
