Thought I'd maybe ask a question that I think is relevant to this discussion.
First some background.
I've been using both licensed Light-O-Rama and the free VIXEN light show
software. Back when I bought Light-O-Rama Vixen wasn't really available yet.
Now it's pretty cool.
For those of you

rtems could without doubt be worth a try but have only used FreeRTOS and it
work.
FreerRTOS usually run scheduler at 1kHz and using one of the newer Micro
controllers like Cortex-Mx which is a very common CPU in these with prioritized
interrupts for higher priorities work really well. There is

The trouble with the Mesa FPGA design is that it depends on a computer with
good real-time performance. It can generate steps but I don't thing you
can run a position or velocity PID control loop on the FPGA.
You asked about "my controler". No this is not my idea, this is how most
current
PCs are cheap, easily available and easy to code on. They provide huge
amounts of processing power for little money and are very well suited to
GUI applications. However they are not designed for hard real time work.
LinuxCNC does a good job but even then it tends to be a bit touchy if
not
makes me wonder why a "cnc controller" doesn't work like a printer (yeah
sounds naive),
but 30-40 years ago it was unthinkable to print something half decent
without using ink and a hand cranked machine (stenciling).
