So sieht meine Steuerung mit EtherCat aus. Servos von Lichuan über AliExpress und StepperOnline über deren Website gekauft. Nutzen alle das cia402 Profil, lassen sich also identisch ansprechen. Einzig die vid (Vendor ID) und pid (Product ID) sind anders, müssen also in der ethercat-conf.xml angepasst werden. Man kann die Treiber meines Wissens entweder direkt am Gerät einstellen oder über die ethercat-conf.xml mit SDOs. Letzteres habe ich aber noch nicht ausprobiert. 

Als IO nutze ich Beckhoff Module (EL1018, EL1008 und EL2008 sowie Potentialverteilermodule) weil ich das besser finde als die IO Pins der Motortreiber zu nutzen. Brauche eh mehr als die Treiber bieten. 

Als LinuxCNC Rechner und EtherCat Master läuft ein Raspberry Pi5 8GB. Das größte Problem hatte ich mit EMV, EtherCat scheint deutlich anfälliger zu sein als was ich von Profinet auf der Arbeit gewöhnt bin. Deshalb habe ich im mittleren Kanal einen geerdeten Metallsteg eingesetzt, so scheinen die Probleme behoben zu sein. War leider im Platz etwas begrenzt, sonst hätte ich das Schütz -Q1 nicht direkt unter die IO-Module gepackt. 

Hi Rod,

Sorry for the late reply — I was traveling with my family and only catching up now.

Thanks for the work you’ve been doing on the installer and the RT tuning side. That’s really valuable and definitely helps lower the barrier for people getting started with EtherCAT on LinuxCNC.

Thanks! ( I haven't done it yet. )

My progress is...

I found ( in "ethercat slaves" command response ) that one servo drive version was 1.07, and anotehr was 2.09 in 3axis. But I have orderd  them recently at the same time.

Yaskawa support person said, this version is ESI version ( in servo driver ? ), but I haven't send ESI file to slaves as far as I remember.
Their suggestion is to use the same ESI file, and sent me the link of the latest ESI file for Sigma X.

How do I apply the latest ESI file to IgH Master and slaves?
I googled it and ask AI how to do it, but I couldn't get the answer for IgH master.

Thanks, I will use this.
I did have to install the non-free version of unrar before I could successfully open the rar archive, unrar-free kept giving up with errors. Attached a zipped version for convenience.

Thank you.
Should we make this "sticky"?
We would appreciate feedback on this.

Looks nice, thank you.

I want to use torque homing ....

Is that where the motor moves till it hits a hard stop to home?
Sorry i can not help more, but no experience with EtherCAT, yet.

Thank you.
If anyone thinks this belongs somewhere else on the forum, please do let us know.
Leaving it here for now.

There was a topic with something similar, but i can not find it (google has become useless), it was quite some time ago, but if i bump into it i will report back.

Thank you.
I would also like to build one such machine, but i have a pretty long waiting list, building a laser and a router now, want to build a small but sturdy mill, a wire EDC, a bigger styrofoam cutter, a rugbot, a normal tangential knife, ... oh well.

Thank you.
BTW, i can not check on this PC as i have no office suite installed.

Did you set the scaling properly?

You are welcomed, always, and thank you for reporting back.
