A line woodWOP cannot be told about
UnsupportedRefused. No file is produced.
What the converter says
woodWOP has no way to say what this line does
What triggers it
The line shifts the origin every later coordinate is measured from, calls a subprogram held in another file, or is a command this converter does not know. Any of those changes what gets machined, so the file is refused rather than written without it.
S /2A X=1284 Y=0How to fix it
Resolve it in the source program first: shift the coordinates yourself instead of shifting the origin, or paste the subprogram in where it is called.
