Thank you for your response, but couldn't you share these files? I'm going to use a maximum of 4 axes and see what maximum frequency I could get..

Sure, I've just dug out the old work and created a repo to share it. If you do succeed, the DMAstepgen module would need to be updated to include the improvements in the RT1052 version.

Helps if I share the link.

Thank you for your efforts.

Following my resent failures this is what I've done and where I am at now:

- Flashed the NVEM with the Remora firmware
- Installed Raspberry Pi OS (Legacy), so Buster 32 bit
- Installed xrdp to enable Remote Desktop
- Followed the guide to install LinuxCNC at remora-docs.readthedocs.io/en/latest/sof...nc-installation.html , but since I had issues with the Pi not booting after installing the realtime kernel, I instead installed 5.15.65-rt49 according to forum.linuxcnc.org/9-installing-linuxcnc...n-raspberry-pi-3b-pi .
- Installed the Remora NVEM component
- Followed Scott's videos to configure ethernet
- Flashed the basic config to the NVEM

- I am able to ping the NVEM at 10.10.10.10
- I am able to start LinuxCNC and get out of emergency stop
- I am not able to request movement. If I do, I get "joint [0-2] following error"

I really wan't to move on and reinstall the NVEM in my CNC and continue with configuring LinuxCNC, but I'm stuck with this error.

Hi, I've just put the STM32 NVEM back on the bench to retest. I could simulate your error when using the remora-eth component. With the latest firmware

github.com/scottalford75/Remora-NVEM/blo...NVEM-STM32-1.0.0.bin

And this config

github.com/scottalford75/Remora-NVEM/tre...es/remora-nvem-basic

Everything is ok.

A full chip erase can be performed in the ST-Link Utility.

I did full chip erase, flashed the NVEM again, uploaded the basic config, but the result was the same.
I did however lower the jog speed from 2979 mm/min to 4 mm/min, and lo and behold it jogs! Albeit very slowly... Anything faster than 4 mm/min and I get the following error again.

So, any ideas why it's like this?

So this will be a LinuxCNC config issue then. Which INI and HAL file are you using?
