Does anyone know how output formats in laserdraw via Corel work?

Does anyone know how output formats in laserdraw via Corel work? When I use PLT the scale is over by 1-2mm, but when I use WMF the scale under by about .5mm but much more acceptable.

Also in Corel unless I have a solid shape, WMF will cut twice even when set to once, PLT cuts once. Alternatively if it’s a solid shape, both cut once.

Which format should I be using? The default is PLT, but the scale is inaccurate. I found a video of someone having the same problem and he also shows engraving and cutting in the one run which I didn’t realise was possible with this machine/software.

Interning video. I wondered what some of those settings were for.
