Post processor warnings

Problems and questions
1

Been meaning to ask for some time now if there is way to make this go away. I get the warnings in the screenshot below, but only when I set the refdistance variable in the operation window.

Go to Options->machine->post processor and click on the ‘edit post’ button.

Look for:

function OnNewOperation()
   post.Text (" (Process: ", operationName, ")\n")
   if &#40;plungeRate <= 0&#41; then
      post.Warning&#40;"WARNING&#58; Plunge rate is zero"&#41;
   end
   if &#40;feedRate <= 0&#41; then
      post.Warning&#40;"WARNING&#58; Feed rate is zero"&#41;
   end
end

Change it to:

function OnNewOperation&#40;&#41;
   post.Text &#40;" &#40;Process&#58; ", operationName, "&#41;\n"&#41;
end
