How to configure drivers 10 and 11 on CONN_LCD?

Depending on which external stepper driver you are using (what are you using?) you may need to change the length of the pulse that tells the stepper driver to move; see the T parameter of M569.
Like I said earlier, external drivers often need different step pulse length. Refer to documentation, or tell us what drivers they are so we can suggest settings.

@droftarts OK, I wish I knew which of the changes finally mattered but I don't. I probed the STEP output with an oscilloscope and the pulses are there and the pulse length is fine. I was able to move the extruder motor first as U axis and then as extruder 0, all is good now.
I want to thank all the people that made suggestions, it really did help a lot, I think we can close this thread now. For those with a similar configuration as mine (CoreXY, three Z motors and two extruders with external drivers on CONN_LCD here is my config.g - this is a work in progress and it's not complete but all the motors are working now as does the bed heater (with a PT1000 sensor):

I forgot to mention that the Extrude/Retract Web Interface buttons are still greyed out and do not work, I can only move the extruder motor with G1 Ennn commands. No big deal.

@catalin59 So I understand you right: you can command your extruder stepper (physical drive 10, mapped to E10 and assigned to tool 0) with the external driver by G-codes? That was the biggest hurdle, congratulations!
Now, to get the web interface activated, you might proceed with your tool definition - adding heater, fan and thermistor, that is. If you still got no physical devices attached, follow @Phaedrux’s advice and try adding a dummy heater definition… I may be wrong, but IMHO, the DWC tool control interface is mainly there to control the temperatures of a tool, so it might need more than just a stepper to become functional.
With the extract/retract buttons in DWC, I'm not sure of the reason why they are still disabled - maybe someone else has an idea?

What version of DWC are you using? I just tried on my machine using 2.0.4 and the buttons are normally greyed out but if I send M302 P1 they become "non-greyed" and active. The same works on DWC 1.22.6. If you are using some other version of DWC, it might be worth trying one of the above.

@deckingman The Web Interface version is 1.22.6
