I believe you’ve got a good handle on that. It’s not G code, but obviously yeah… “some sort of G code” is probably the best way to put it. I’m sure they have some internal code name for it.
But, yeah… I’ve only hit the memory limit a couple of times over the past couple years, and it’s frustrating. But not the end of the world usually. And, yes… A desktop app would obviously alleviate that. But, hey… It is what it is as far as that goes… It’s clear they have no intention of changing that. And I’ve gotten so used to that that I don’t even think about it anymore.
