This is typical of the move length and speed not being finished in the timeout requirement.
But that seems strange on the latch return.

What version of linuxcnc are you using and can you post a pic of the probe settings you are using (when it failed)

If you have two inputs on the Mesa card, connect a probe to each, then in the HAL file connect those two signals with an OR component. The output of the OR would then be connected to linuxcnc's probe input.

Actually I've just had another thought, what version of RPi imager are you using and what particular OS ?
I'm not a windows user and some people have had issues with RPi imager ?
Do you uncompress the downloaded file or just point RPi imager to the compressed file ?

Hi Rob,

Thank you for your help and new information: I have missed the two links you posted on the previous reply.

I am using Ubuntu 24.04 Noble Wombat and Raspberry Pi Imager V1.8.5 to write image.

I downloaded the linuxcnc.org/iso/rpi-4-debian-bookworm-6...25-01-27-0404.img.xz and use it as is.

I did check the kernel with uname -a, and the output is Linux raspberrypi 6.12.11 #1 SMP PREEMPT_RT Mon Jan 27 02:47:25 AEDT 2025 aarch64 GNU/Linux.

AND I HAVE BEEN ABLE TO GET PNCCONF's Test/Tune Axis to test the X-axis motor: thank you again Rob.

-- For PNCCONF to work, we need to use menu-config to set Locale to en US.UTF8, after setting the locale, I had to restart the machine, otherwise the locale does not seem to take effect immediately.

To verify the machine locale, on a terminal window, run the locale.

Best regards,

...behai.
