Trouble with Cia402 drive configuration

So now this is what my .xml looks like:

Should I add back in the dcConf and pdo assignments?
When starting LinuxCNC I get:
LCEC: Invalid appTimePeriod of 0 for master 0 (should be 1000000).
LCEC: slave 0.D4: FAILURE: FAILURE: more input PDO entries configured than your hardware supports.

Axis 1 has 12 PDO entries, vs a configured limit of 8. You will need to edit your XML


It's still throwing the 1A00 and SDO Download errors.

Great, that's exactly what I was looking for.

It works well, but two things could be improved:

1. If I press a macro button a second time that doesn't do anything because it's already executed, e.g., "Goto Machin Zero," the LED doesn't go out; it keeps blinking. It blinks until another macro does something.

2. Button 10 has a hardcoded name of "MORE MACROS." It would be nice if it also took its name from the ini file like the other buttons.

Hello Experts,

Is there any readymade package with LinuxOS+RTKernel+Ethercat Master prebuilt.?

Can someone please explain the core concept of Ethercat communication compared to traditional step and dir method?

I was wondering what parameters vary from machine to machine in terms of Ethercat configuration?

For example, I have seen that the Ethercat module needs the network card ID when installing/configuring Ethercat Master.
