Yes. That leafboy guy doesn't even have a public contact info. No way to ask him if he has a plan about the situation.
Too bad I have an AKZ250 on the way to me. I wanted to get a Mach4 license to use with it but I guess it's time to get an ESS.
The Chinese released an Ethernet BB for Mach3. It looks nices but no info on Mach4 support in the future too. The Chinese just want to sell without support.
