I use MeshCAM V5 to convert a part into G Code. This is then sent to my CNC router to cut the part out. I have used other 2D drawing programs with no issues but when I use PTC it creates a very large part. After looking at the scale difference, I found that it is exactly the scale difference of converting inches to mm. Any idea why? Thanks in advance.
Likely need to set an option in config.pro for exporting.
Do a search in config.pro for any STL options.
