I bought an open frame too because of the flexibility of sliding things under it, unfortunately I soon realised I needed to enclose it and use an exhaust system because of the fumes!!!!! Mine didn't come with software, normally I tend to find free software that generally works but in this case I ended up actually paying for Lightburn and consider it money well spent, it's an excellent piece of software for laser engravers with lots of user guides on youtube.
These things have lots of creative potential for leatherworkers.
