Funny message when reply to a topic

Category: Forum Questions

It looked like forum admin emails, hence the reason I xxx them out.

I sent Andy & Rod an email with a screenshot, hoping that they may be able to forward it on to someone that knows about the forum.
It happened before all the "crack spam" was removed and was concerned that something "bad" may have happened.

7i95 randomly throws error with raspi b

Category: Driver Boards

I think it was the wording "reset". To actually reset a 7I95T
you need to cycle the power (or issue a reset command but
LinuxCNC never does this)

If this is a real time error, it may be that the servo thread period
needs to be increased to say 2 ms as 1 ms is marginal on a RPI4.

Developing a Raspberry Pi Pico-based I/O Board for LinuxCNC

Category: General LinuxCNC Questions

Hi everyone,
I recently ran a benchmark test on my LinuxCNC setup to measure the data request speed, and I thought I’d share the results with you all. I’d love to hear your thoughts or any suggestions for further optimization!
The setup was connected as follows: [Linux 4.19.0-27-rt-amd (core i5) PC (3 byte send 5 byte receive)] -> [switch (TL-SG1005D)] -> [W5100S-Pico]. This was a non-realtime throughput measurement, and the result I got was a stable 2500 requests/second, which I think is pretty solid. I’m curious about your experiences—has anyone else done similar benchmarks, and what do you think of this performance?

Thanks in advance for your input!

If you ever set the update rate to 0, you can never change it again or the driver will hang (this is a known bug)
