I’m sorry your unhappy with your GF. No one will likley say anything to make you like the machine or find it worth the effort it takes, but there are some solutions to the frustrations you are having. If this really is more just a post out of aggravation and you are just needing to vent a little, ignore the rest of my post.
I just want to check and make sure you know all the PF material is in a drop down list and you don’t really need to have the camera read it. (I’ve noticed there have been a few people who didn’t realize the can manually select material.) One of the most common reasons the camera doesn’t recognize a QR code is too much outside light from a nearby window or light hitting the tray and overexposing the code. Not sure if that’s the issue you have, but it could be. If the camera is a ongoing issue for you, be sure to make a specific support post about the camera and GF can check to make sure it’s working correctly.
What do you mean by the material not working well? Is the wood splitting on the boxes you’ve made or some other quality issue? I don’t mean this harshly, but if it’s a matter of boxes coming apart at the joints, that’s on you and not the material. No material will hold up if you don’t use the correct glue or construction techniques or you use the wrong material for the job. Working with wood does take some practice to get good at it as each wood type has different grains etc. which effects it’s strength, how it takes paint or stain and how it lasers. Acrylic can be tricky to glue as well and you have to sue the right stuff.
I think a lot of people get frustrated with trying to make there own files and it seems like a daunting task, but learning one of the design programs gives you so much more freedom with the machine. It does take some work though and there is learning curve, so it just depends if you find it worth the effort. The only suggestion I have is keep plugging away at it as practice does make perfect. If you want to rely on purchasing files there are thousands of them available online. You might have already visited these paces, but just in case these are a few of my favorites…
As far as support goes, is there something specific you’ve asked for help with and they haven’t responded? If that’s the case, maybe post again and we can try and resolve it for you.
