LinuxCNC + Orange Pi (allwincnc)

Hmm... Nothing else to be done? I presume none is really using this... Right?

People are, but the configs as left by the dev are what they are. It's in Beta. It needs some work.

TomP is working on it as well as a few others. I hope to have some time later this summer.

The cpu cores should NOT being doing be doing any speed changes. They should be configured after reset to come up to a stable frequency and just stay there. Any core speed changes will cause too much latency even for a servo thread. No base thread is used with AllwinCNC on the big ARM cores. The integrated ARISC does all the step generation at its own locked core frequency.

Tomorrow I will try to have the CPU at a fixed rate somehow. I feel it is close to work, just need to figure out what can be done to solve this latency issue. This is why I asked here if someone else is using it in a real case scenario. Someone else could have stumbled on the same issue and have a fix or direction.

When running the latency test you should be doing other things on the system like opening and closing a file, copying files etc etc

Thank you very much! I will read this carefully and run some new tests tomorrow. Just for reference, which values should I be expecting in this H3 board? What are common values?
