You should get the vendor's ethercat definition, which provides the scaling function....

Oh so those are now all in one file?
There were 3 back then, quick start, documentation and integrator's manual.
I recall thinking "how is this software under 5MB in size while documentation is nearly 30MB???"
Good times.

Just a heads up. Tommy's link is to Linuxcnc v 2.6 and our release version is now 2.9 so it will be obsolete in places.
The PDF files are available from the Documention page but are just a copy of the content in the HTML version which I tend to use in preference,
But none the less I too was gobsmacked when starting off to find the documentation runs to 1347 pages!
2.9 version: linuxcnc.org/docs/stable/pdf/LinuxCNC_Documentation.pdf
 

Can you post your config files?

What part worked?

The motors will move even if the TMC doesnt configure. motor0 and motor 1 are connected to the same output buffer, if the buffer is damaged motors0 and 1 wont get the enable signal it looks like

Hi. Thanks for your help after a new cable this is now working.

However I noticed and issue with Stepconf wizard. It will not allow you to have multiple outputs as enable. If I set pins on the second breakout board to enable those setting are not reflected in the HAL file. However If I manually create the line for port1 then enable works on the second card.

Unsure if this is correct behaviour. This may also be why I could not get the Breakout board working. Just possibly a trap for new players. It is tempting to use enable as the test for the breakout board as you have access to switch it from the main panel without running any gcode. But without manual intervention this will not work.

Thanks.

That last piece of the puzzle did it !!!!!!!

It now  launches, embedded.  

Thanks so much for all the help !          Hopefully others will benefit from this adventure.

The Nativecam looks to be a newer version than the one I have been using.   Now I have to get current with the changes over time.
