7I92 read and write latency spikes

The DYN4 in analog is not any better. I had a 5ms delay between analog outputs and encoder signal back to the mesa card. Same timing issues with DYN4 in position mode with quadrature input. I have equated them to being overpriced hybrid step systems at best.

That is good to know and I will reconsider upgrading to the DYN4.
What was the test setup you have used to identify the delay?


Could you replicate this issue with a drive from another manufacturer?

I just read your post on the other thread about the delay. The delay sounds like the delay is “normal”. Oak boards adjust the delay during setup. Same with other drives with absolute encoders. Is there a way to do the same in LinuxCNC?
