For Raspberry I think following this guide should help: github.com/by/RT-Kernel

Only after git clone, download this patch:
forum.linuxcnc.org/media/kunena/attachme...ernel-realtime.patch
Then enter the Linux folder and enter: git apply ../sys-kernel-realtime.patch
After make menuconfig make sure that these are also selected:
forum.linuxcnc.org/38-general-linuxcnc-q...6-12?start=10#315643

These are Linux kernel patches, so I guess where the kernel devs hangout.

Hello,

Got the drive working again today, the parameters for Control Mode and Pulse Type were indeed wrong (so you were both right

Turns out that my backup parameters file was not good at all, I ended up just copying the working parameters from one of the X drives to the new Y drive. Both axis have the same mechanical setup, gear reduction ratio etc...

@ihavenofish : you are right, these drives have CAN bus capability. I made this choice at the time as I was not quite clear about the various options. Now, I wish I had chosen the E version that offers EtherCat...

I'm thinking about upgrading the whole setup to EtherCat, possibly running LinuxCNC from a RaspBerry. Pi. That would allow me to get rid of the PC/Parallel Port limitations, move all the hardware inside the control cabinet, and have more I/O to finally add some extras to the machine.

Thank you all for your help, great to see this community thriving !

Is there a GitHub tracking thread (or something else) for those patches?

I would be really interested in following that thread.

hahaha

These things happen.

We're making some headway towards getting a 6.12 kernel going with rod's image builder.
But despite what the recent skuttlebutt suggests for arm platforms it seems that some patches are still required for realtime.

I have made a mistake. I thought the kit I bought gave no *physical^ access to the SD card. But, it does.
My apologies for the trouble and misunderstanding.
