when I create a file in lightburn and load it into my Masso controller the dementions do not match. example. If I want to lets say engrave a 4in. slate coaster I will set the size to 3.750 because of the edges being tapered. when I save the file to thumb drive and load to the Masso controller it will show up on the display as something like 4.018 and if I run the file it will over shoot the edge of the coaster just a little. when I start doing more precise projects these dementions need to match. I started emailing tech support but left for a week of vacation and haven’t finished off what I started so figured I would post here incase any one else has had a similar situation.
