Also you should check out a free software called ECAM. It's great for 2D CAD too, and it also has very simple post processor editor, so with a few tweaks you can get the Gcode you want without having to manually overwrite it.

My answer may be slightly late . I was facing the same problem a few days ago, so I started looking for answers on this forum. Later I found very simple solution to work around this bug of mach3 (A axis rotates even in linear move after a g2/g3 arc). What I noticed is this only appears when the specific linear move is perfectly parallel with X or Y. So I started rotating my sketches. It turns out even an angle 0.01 degree is enough to avoid the problem . Just make sure your Gcode cordinates have enough decimals for this rotation to become visible (I use 3 decimal)
