CC export gcode with duplicate paths

The gcode that Carbide Create exports sometimes has duplicate paths. I’ve attached an example.

I am trying to run a finishing pass in Carbide Create. My toolpath has the following parameters:

  • Start Depth is 0.3
  • Max Depth is 0.34
  • Depth per Pass is 0.04
    Thus, it should only run one pass. However, in the attached gcode, you’ll see that lines 15-47 are repeated starting at line 48, at the same Z height (Z-8.64).

Here is the C2D file and the NC file generated.
test.c2d (30.1 KB)
test.nc (5.8 KB)

I’m running Carbide Create Pro build 514.

likely a math rounding issue; your max depth is “exactly” the total remaining, depending on how floating point rounding ends up, you end up with 2 passes…
