Ok that fixed the feed rate but I found another problem which I manually fixed:

Here is a Gcode snip of the test file I am using

N0020 (Post processor: Mach3 tangential.scpost)
N0030 (Date: 17/09/2014)
N0040 G91.1 (incremental IJ mode)
N0050 G20 (Units: Inches)
N0060 G53 G40 G90
N0070 F1
N0080 (Part: New)
N0090 M6 T4  (Fresadora/Router, 0.01 in Di├ímetro)
N0100 G43 H4 F100
N0110 M03 S1000 F100
N0120 G00 X5.5118 Y4.3307 Z0.3937

Mach 3 seems to skip lines 130, 180, and 230, which are G0 moves of A, The weird thing is that the A axis moves to the position called for in the following line for example when line 180 calls for A to move to 71.6312, it instead moves to the position called for in line 200 which is -288.3688, so that when it actually goes to that line it does the arc but not the A axis movement.

What I did was to add a G1 on lines 130, 180, 230, etc... and now the A axis moves to where it is supposed to move.

Any ideas on why G0 moves of A axis are being skipped?

Sorry for the monologue!

Unckecking the Ang Short Rot on G0, seemed to do the trick, it takes a little more time to get to the desired angle but I can Live with that.
