The problem with mach 3 is producing the g code for the machine. It does work but it takes a lot of time compared to the dedicated laser controller. If you were setting up the machine to repeat the same job time and time again mach would be great. But lasers are great because they are fast and easy to use, mach takes the ease of use part away in some respects. I think you made a good decision buying this machine and I look forward to your review.
