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.
