Hello

I use the post procesor from fusion 360 for Mach3 but i have some problems with the code because is milling in my model some times. I will leave my code is just a contour for example but the code is doing strange things.

Your code looks like the photo I attached. If your machine does anything other than what the photo shows, it is an issue with the machine and not the code. Maybe losing steps or something?

HI @andrei2306KSQQ6

Thanks for raising your concern via Forum.

You can remove the NC codes ( not required ) by simply commenting the respective code snippets from post.

To edit the post you can use the Visual Studio code.

For detail info about the post editing please refer the FAQ link

1. To omit the codes from header

a. Go to line number 338

b. Put'//' in front of below codes.

 writeBlock(gAbsIncModal.format(90), gFeedModeModal.format(94), gFormat.format(91.1), gFormat.format(40), gFormat.format(49), gPlaneModal.format(17));

 switch (unit) {
  case IN:
    writeBlock(gUnitModal.format(20));
    break;
  case MM:
    writeBlock(gUnitModal.format(21));
    break;
  }

c. Go to line number 774. Give condition in 'writeRetract(Z);' to omit the homing codes from header but it will appear after tool change.

// retract to safe plane
    if (!isFirstSection()) {
      writeRetract(Z);
    }

2. To omit codes for program end

a. Searh 'function onClose() '

b. Put'//' in front of below codes.

//setCoolant(COOLANT_OFF);

//writeRetract(Z);

// writeRetract(X, Y);
