It was already implemented in the version 4 and still it is. I'm using 6 of these boards with smart serial to control a robot.

Well just recently i have talked with Mitutoyo Application and Services engineer(From Japan) according to him Linuxcnc Could work for motion part only and also requires to develope some kinametics coz CMM and CNC both use diffrent kinametics and he also suggest me to lookout for develope DMIS(Dimensional Measuring Interface Standerd) application you required Point Cloud Library and 3D cad data reader and converter and also high speed(in term of time not velocity) interface for reading Feedback Encoder and probe signle interface.

The service is already enabled:

and the udev rule is set:
cat /etc/udev/rules.d/99-ethercat.rules
KERNEL=="EtherCAT[0-9]", MODE="0777"

I have a feeling that its more like a timing issue or has something to do with the IPV6 message in the dmesg logs:
[    5.551029] IPv6: ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready

If I do an ip a right after the start of the system I geth this output:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

But if I then restart the service, the eth0 is gone from the list:
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

Maybe network manager tries to configure eth0 (which is the CCAT interface of the CX2040)

I’d try google and any of Jeff Gerlings stuff on YouTube.

But honestly I think you’re using the wrong tool, the RPi5, for the job.

The small Lenovo’s that are popping up around eBay and such are a far better solution.

Hi Grotius,
i have a few spare ethercat stepper drives by leadshine (6amps) and a couple 230v operates servo drive and motors (750 watts) by Veichi that I could send to you for your machine trials.

This way you will be able to isolate the effects of pulse and direction jitter over ethercat on your machine.

Let me know our DM and we can set something up.

I think fom memory you need to set a udev rule for it to persist on a restart. Its covered in the sticky.

You can probably just delete all hal lines with pwm in them to get running.

Its likely the 7I95T configuration boilerplate came from the 7I96S which always
has at least 1 PWM channel

Linuxcnc works fine with Raspberry Pi 5, but when I watch it on the GUI, the positions are a bit delayed. When I use it with a PC, there is no problem. It communicates with 6 servo drivers and a PLC. It would probably be better if its speed increased a bit.

@PCW - No configs in the Spindle tab. I set one of the outputs to Spindle brake. That's all. All else was default. I will track down the secure boot problem.

I think I may give up on the hypertherm thc.
I went ahead and ordered a thcad but I gotta figure out the z axis. 
I have the hypertherm dc h bridge z axis or was offered a stepper powered z axis from a candcnc setup.
I have a mesa 7i97t, but I’m not sure if I can control either of these z axis’s with it, since it has analog outputs for servos.
I assume getting the stepper axis going would be easier than the h bridge, but I’m often wrong.
Or maybe I should just buy one.
I also know I’ll need a driver. I have an old gecko 540 I could potentially use, but maybe a single axis driver would be better suited. One that’ll work with 7i97t’s analog signals? Or maybe an h bridge driver makes sense?
What do you guys think?

1. The card name in the hal file is 7i95, not 7i95t

2. Did you setup a pwmgen for spindle or some other use?
(there is reference to  non-existent pwm hardware in the hal file):

./main.hal:66: Pin 'hm2_7i95.0.pwmgen.00.enable' does not exist

3. You don't need a num_pwmgens statement anywhere

(unless you want to disable one that actually exists in the hardware

4. There is an unrelated issue with your setup, likely related to secure boot being enabled in your BIOS:

iopl() failed: Operation not permitted
cannot gain I/O privileges - forgot 'sudo make setuid' or using secure boot?
