from Clearpath manual:

The setup time is 25ns not 25us, so instead of 1:1:25:1 I suggest 1:1:0.5:0 in the M569 T parameter. My suggestion to use 0.5us setup time is to allow for possible skew in the opto isolators.

PS - as per the wiki docs, when remapping axis drivers with M584 you must also re-specify the extruder driver numbers.

But I do not have extruder and Z-axis (this is simple drawing arm). Do I still need to include them in config.g?

Yes, so that any commands you issue that relate to extruders (e.g. M350) don't also affect the motors you have remapped. You can add e.g. E10 if you have no extruders.

@jaredc Yes I am running my CoreXY with Clearpath motors on X,Y and Z. Although I have to make a confession, I purchased a Duet WiFi months ago to replace the Rambo 2 board but got interested in using the Delta Smart Effector and built a Delta instead, works great and I really like it.
Anyway to make sure the the Clearpath motors work with the Duet WiFi I installed a Duet WiFi today, did a rough setup with RepRap Configurator, installed the Duet Expansion Header Breakout board and connected the Cleatpath motors turned it on and tested, The Clearpath motors work just like they are supposed to. About 4 hours to replace the board. Next step is tune everything for the Duet WiFi.

Ed, can you please share your settings? I get stuck with config.g Clearpath did not want to move

I do not know how to copy things to this forum, try the attached config.g file. If it doesn't work I will create a text file and sent it. I used the RepRap Configurator, if I could I would sent the entire sys folder.

@dk
The config.g file I used is from my back-up folder, sorry about that. Try this file. It opens Repetier and then use the "Edit G-Code"
