Not sure how modern you want but the kernel on the image here is 
5.15.27-rt35-v8+

That's great, thanks Phill!  It linked to just what I was looking for:



That's a fork of the official RPi kernel, reconfigured for Preempt-RT, 
with prebuilt debs for armhf & arm64.


The debs installed on top of a clean up-to-date pi-gen Bullseye armhf 
image (so Raspberry Pi OS aka Raspbian, not the real Debian).


The latest "release", 5.15.65-rt49, did not boot on my Rpi4, but the 
previous one, 5.15.40-rt43, did.  Latency is a bit worse than Raspbian 
Buster with the 4.19.71-rt2 kernel but probably usable.

Re: [Emc-developers] linuxcnc on raspberry pi bullseye?

[Rod Webster]

Sorry to raise an old chestnut in passing
We should only provide an interface to the IgH software, nothing else. That
software is Open Source. That is clear.
The IgH software is actually stand alone on the PC, installed from its own
package from their repo if you follow my instructions
 
https://forum.linuxcnc.org/ethercat/45336-ethercat-installation-from-repositories-how-to-step-by-step

It would be up to the user to install the IgH package if he wanted to
use ethercat devices, linuxcnc would just provide an interface to the igH
package which the user may or may not install or use. That to me
quarantines Beckhoff to IgH well away from linuxcnc.

Accessing different software packages by published API's is nothing new...
IgH have made it much cleaner to do now they provide the repository.

That seems like it could be very important. Is there any suggestion
that Beckhoff have changed stance (it would be in their interest to do
so) or is this one-sided from etherlab?

If the latter, are they omitting to mention, or do they have new
information or a new legal interpretation?

I would love to see EtherCAT fully integrated into our releases, but
the Beckhoff license was weird.


I think it is still a bit weird. Just randomly checked out

https://gitlab.com/etherlab.org/ethercat/-/blob/master/master/datagram.c

and this reads - below the GPL-blurb:

* The license mentioned above concerns the source code only. Using the
* EtherCAT technology and brand is only permitted in compliance with the

This is self-contradicting, I tend to think. Not to use the brand name is 
already difficult enough, but not using the technology?

Best,

[Emc-developers] G96 Constant surface speed, have to move some distance before active

[Nicklas SB Karlsson]

Change tool and use constant surface speed G96 with proper parameters. 
Then spindle is started without moving it run at maximum speed 
regardless of which surface speed S have been set. Moving some distance, 
guess it might depend on tool diameter or radius then S parameter start 
to work.


Is there any good reason surface speed should start at maximum until 
tool is moved? Or would it be better tool does not have be moved before 
surface speed is active?
