I'm using alpha version.
And correct stepper numbers 1 and 2 for the two motors - it was a typo in the post.
I'm now using the configuration generator. I'm hearing the motors sing when in spreadcycle with tmc2130 and tmc2130_quiet. But there's something else weird happening so will investigate it on the weekend.
Thanks for all your help. Chris
