G93?? Are you sure you don't mean g95??
No. What myself and a lot of router users are looking for is G93 mode. https://www.ganotechnologies.com/cnc/rapidrotary/
UCCNC is constantly going to be evolving, whether all users like it or not.
Look at it like this. There are probably 100,000 Mach3 users that at some point will be switching to another control, as Mach3 gets harder and harder to keep running. Then consider how many new people are buying CNC machines every day. I'd be trying to greatly expand the user base, rather than try to rely pn existing customers to fund development.
But that's entirely up to the developers.
And I'd gladly pay full price for an S Curve version of UCCNC, if I had too. But many would not.
