Thanks for chiming in with your experiences and clarifying exactly what your issues were. It sounds like your frustrations were about things that I am seeing as positives. I'm not looking for something where I need to get under the hood and do any coding or deal with interoperability issues in getting things to talk to each other. I have those skills, but on this project I'll be quite content to just get it set up and functional as a somewhat plug-and play system and then largely forget about it. From what I can see, in its out of the box state it has more than robust enough features for for my needs, so I don't anticipate ever hacking into it. Looking through the screenset, it has as many or more control parameters than the light-industrial plasma cutter that I currently have access to. The Simplicity also is probably plenty robust for me, even with its more cumbersome and primitive interface.
Thanks for your impressions of Neuron as a business/customer support as well. As a potential buyer I do really wish the website and PDF documentation was current with the UCCNC info. But I also happen to have a website where I sell something, and it too is in dire need of updating, so I'm in no position to throw stones. It didn't take much asking around to get what I needed to see. As a customer I tend not to need any hand-holding and would only reach out if there was something I couldn't solve even after my own thorough research. So hearing that Andrew has even Skyped with people to help walk them through setup, to me says a lot and makes me totally comfortable making a purchase from him.
