I'm always happy to help where I can. I wrote a detailed SCAL5 user manual that will help you with all of the functions in SCAL. Unfortunately, I can't cover every cutter that SCAL works with because there are just too many. But usually, I can figure out enough to help someone with a cutter that I've not personally tested. Here's a link to my manual:

I'm contracted with companies focussed on the crafting market and crafters expect excellent support. So, that's what I do! If you're on Facebook, you can probably find an active GCC group if you have any other GCC-specific questions. But otherwise, just feel free to post here and I'll try to answer.
