Been working on the Z axis today, not done it all by any means as work keeps flipping geting in the way...

Not drawn the plates that the Y axis Carriages attach to yet (simple so won't take long) ot the Z axis Stepper plate which is going to have a pocket for the stepper milled into it with slots so the belt can be tensioned. The Z carriages and rails are just blocks drawn to the correct dimensions but with no detail, couldn't be bothered and couldn't see the parts in the online library to download but not looked too hard!
