So those parts now show a shipping date of 8 May. And Element14/Farnell show them shipping in August, so time to choose a different supplier.
In the interim I've mainly completed the internal wiring of the control enclosure. That's a huge job in itself.
Here's a photo showing the hinged backplane in the open position. The stepper drivers are unplugged as I have not tested any thing yet so want to proceed one axis at a time. I've installed 3 drives (CL86T) for X Y Z and there is room for a future 4th axis, which the controller can handle.

More later in the week - hopefully including a test of a motor.
