Thanks Jazz,

Will set those tomorrow.

I might have to re-visit my linear rail parallel setting - something appears to have moved slightly during build as the top-right corner of my bed seems about 0.3mm high compared to the other three which are relatively true. As you can see in the pic, I have mounted a DTI on my spindle clamp and was measuring the bed while jogging around.

Its a bit of a pain as it means almost full strip-down, not sure i can shim the bed that much to get it happy, will have another look tomorrow.
