General Questions about using ethercat

Lcec isn't ethercat it is just an interface to ethercat, at the most a driver to use ethercat.
How well do you think your method works in this case?
Maybe if there was a detailed guide on how to set this up, and what to do in case of problem?
More than once I have wished to refer to RTFM but there isn't one.

Thanks for the help, it loaded after changing lcec name to D1 and D2, and after I commented out several lines.

ethercat slaves shows both are on OP mode, but I am sure I don't currently have enough pins defined for motion control.

I need to work out what those line problems are, some are just not defined and some are type mismatch, but I may be able to work that out.

Good to hear, wouldn't surprise me if you change D1 and D2 to X and Z.
That config should be enough to move the axis. Try it.
Then you need to add limit switches and other switches if you have that, spindle control, pendant or gamepad and so on.
Now when linuxcnc is up and running you can easily inspect pins' values using halshow.
The drive and motors are closed-loop I guess, then you will see actual-position change when you rotate the motor shaft, even by just a little if the motors are active.

I am unable to get the motors to move, they are open loop steppers.  This is my first use of linuxcnc so I don't know much, but I tried power on, then home and got the following:

Were can I get a definition of command number 110?

You will not be helped by knowing command 110.
It's the following error on the line above one need to react on.

They move a tiny tiny bit or not at all? Does the shaft stop free rotation?
Anyway, the drives are closed loop drives, you need to set them to open loop mode so they ignore the input from the non-existent encoder on the motors.
I searched briefly for a manual but couldn't find one - Lichuan CL3-E57H?
So you have to look in the manual, or perhaps there is a configuration software with it, I saw comments that suggests that. Turn of closed loop, enable open loop.
Hopefully it is that easy.
 

According to the manual, parameter 2301 indicates open/closed loop and is set to open loop:

ethercat upload -p 0 -t int16 0x2301 0
0x0001 1

The shafts make no motion at all, the velocity display changes to 200 for an instant and then back to zero.  I can easily turn the motor shafts 

It looks like the operation mode is not set. The manual says to use CSP mode by setting 6060 to 8, then set 6040 to 0x6, 0x7, and 0xf in sequence

ethercat upload -p 0 -t int8 0x6060 0
0x00 0
ethercat download -p 0 -t int8 0x6060 0 8
ethercat upload -p 0 -t int8 0x6060 0
0x00 0

so the value is not being set via ethercat. How should I do this?
