I guess ChatGPT looked at this thread to come to that answer.
I read more than half of this thread yesterday. Some 8 pages or so in there are many working configurations, and people with success.

@John,

Maybe that's the case, but this is solvable.

I am writing some new code. We are free to change the state machine transitions for Lichuan.
Here you can see how to set states. In fact it's just a matter off setting a combination off bits in a sequence.

Currently i am waiting for a new servo drive, so my code is halted. I dont have a Lichuan here, so i can not write code for it
to solve any problems.
 

Told you, was just to sit back and wait
That milling machine looks and sounds great.

Can you share the ecat-conf.xml file you ended up with? Can help the next guy out.

And don't forget that "ethercat for dummies" post, greatly needed.

Thanks. When I use the naming in the linked config instead of the naming from docu it works!
I can see dir and step signals now on the correct pins.
One last problem before I can test with the machine. I use an enable signal for the stepper driver. I see it on the pin, but inverted. Is there a possibility to invert output pins at raspberry pi 5 or should I better do it in hardware?

It is a RPI. 
When I run the yzEllipse75.ngc, the machine encounters an error related to IMG_6867.JPG, IMG_6868.JPG, and IMG_6869.JPG.

Brilliant, that makes complete sense now. I'm a Linux noob so I'll probably ask a bunch of questions with seemingly obvious answers. I do know how to search so I try to keep it to a minimum.

it go zoom zoom now



next steps:

IO
modbus spindle control
UI

getting there.

IndicatorMixin is not meant to be used directly. It is 'mixed in' with another button widget such as Qtvcp's PushButton widget or IndicatedPushButton widget

First hint is here:
The GPIO line PIN3 can not be found.

PIN3 isn't a name of a pin, pins are named as per man page.

the config im tryng to use works in version 2.9.4, tomorow i will post my config here,

Have a look at Fanuc style numbered programs M98 Pn Ln

And it was great to see an Aussie take the win in the Moto2 at the British GP.
I feel sorry for Dixon, no Binder to blame for his performance.

Mine were 10 pound poms.

And to be sure we're quite proud of Australia being built by convicts.

Insult an Aussie and they'll take on as a badge of honour, Rats of Tobruk is an example, something the OP fails to understand, tho the little weasel hasn't bothered to reply.

Index to major thread, there's a section regarding your query with an example for a simple 3 axis machine that works.
