CNC milling with open source software

Eventually, something actuates a servo, and servos don’t understand iteration. Do you agree eventually something with g-codes level of detail must exist (even if it’s just unspecified internal commands)? If so, do you agree you’re just advocating for that layer to be part of the machine?

Speaking from user space that has G65 macro-b option, not machine tool builder (sudo) space.

I think of it more as an intermediate language. Interpreted on the CNC control and JIT compiled to whatever the RT system needs for servo control.

It does exist and a strict subset with enough primitives to bootstrap an application VM should continue to exist.

I am advocating for a DSL one layer up to be part of the CNC machine with support offline in say the JVM.

I want to answer this question, “how do we deploy MBE?” https://www.nist.gov/news-events/events/2019/04/model-based-...

The answer needs to be a single digital file that can render real parts and virtual parts. Why not?
