I was just going to post the 2 computer communication for checking work… Great guy, great software!
This post is very informative now that I’m reading more. You have way more knowledge on this stuff than I do. I think I’ll take some time and soak it in. But,
I do remember reading along time ago that sheetcam does communicate with mach3 when it’s running and it was advised to have it on the pc that runs your machine. My old mind just can’t remember why at the moment. Time for a refresh…
My issue after reading the “hack” is what happened to me. Resetting my sheetcam on my new profile, I set it to ms, and put in 300… I’m going to remove my post to remove some misguided info. Your a wealth of knowledge James!
That’s why we call him Professor Hatch!
If you check the Sheetcam forum you’ll find posts by people who will point you that way because you’re right. “Interpreting” the license any other way than 1 license for 1 machine isn’t valid.
But if you’re a regular guy (not a big commercial enterprise) just drop him a note and let him know what you’re doing and ask for permission and he’ll likely let you run one in the living room and one in the garage
