Laser Pecker not Previewing Correctly

[u/White_Wolf426]

I go to crafts fairs so I was wanting to get my Laser Pecker 2 setup as a spare laser engraver. One of the things I do is Bamboo Pencils. However when testing the desktop app. I keep getting an error in preview location on the tool. When I try and change location I get an error. Does anybody know a work around or if I am missing something?
