Looking good now Neil !

I'm no expert here but on my control layout I earthed the stepper driver end of my shielded cables, with the shield running all the way out to the motor without interuption. It looks like you have earthed the 'middle' of the cable if you intend to connect another cable from the terminal blocks out to the motor?

The photos are close in so I might have mis-understood. But you might be better turning the stepper cables around so the earth connection is done on the driver end, and the shields are joined to each other at the terminal block. Or better still might be to complete the run from stepper driver to stepper motor in one complete un-interupted cable, and earth the shield at the driver end.

Someone may jump in with the science on this one, and I could easily be wrong (!) but that was how I interpreted the earth shielding requirements.
