Maybe I should of reworded it a little better.
I did not move away from the Trapezoidal screws due to a problem as such.
Just that a 1605 ballscrew with custom machined ends & ballnut, inc postage from Chai was cheaper then I was expecting.

One thing I would say is stay clear of the tb6560, I think I was one of the 1st on this forum to play about with them drivers, and it was nothing but hassle.
I do know some people that I using the newer tb6560 boards without a problem.
But nothing beats having good drivers.
I am / was using LeadShine 752 Drivers, but I am in a middle of a upgrading with NDA steppers & drivers.

Just waiting for some more funds, and soon my current cnc router will no longer be classed as a desktop unit, going to need a better shed.
