A follow up question if I may?

You originally said you were using AXYZ postprocessor, why have you now changed to using dxfs?

If your machine supports the AXYZ postprocessor it will be more efficient to directly generate G-Code from CAMduct,

as you can control your speeds, cut direction and cut order etc. within CAMduct and output to the machine.

You just need to get your Tool assignments set-up correctly.
