Time for a long overdue update on my progress.

I followed advice from here and upgraded -
1, all the steppers to 425oz Nema23s from 60oz Nema 17s
2, the stepper drivers to external drivers
3, to a 48v 600w power supply from 12v 750w
4, the y-axis to dual leadscrews from dual belt
That lot is all in and working a treat

I've got limit switches on both ends of each axis
And I've made x-axis and z-axis carriages from 6mm aluminium

I think I'll need to spend time tuning it all in, it's a bit noisy and lumpy in places.

It's all there really. It just now needs tidying up, ie cables in drag chains, a controller board making up, e-stop etc.
Then I need to sort out a waste board and a router/spindle of some sort. The original plan was to use my main router but I've since realised that it doesn't dis-assemble to a mountable form.

It's been fun building it
