I have been working with Lightburn for years. I have had very good experiences with the company, especially when it comes to support. If a bug is found and published in the LB forum, it always takes only a few days for a response. Either it is promised (and kept) that the bug will be fixed in the next update, or a patch is released within a few days.
The support is as good as Andy's at his very best.
Lightburn can output GRBL code for lasers, you can theoretically already create 2.5D G-code programs with it.
I would be interested in testing MillMage. Is there a contact or a download address?
What do you mean by “Interrum”?
What I saw of MillMage was in the LBX livestream 2023, when the program could do as much as CamBam 0.8, 15 years ago. It just had a nicer interface in the style of Lightburn. Back then MillMage could only do GRBL and no G-Code.
I have hardly found any new information since then.
