Hi Peter,
looks good.
A few years ago I helped a customer with a design for a plasma table. He cuts small parts as a rule so he wanted to
be able to fit a 1200 wide sheet but the y axis only had 600mm of travel so the ends of the sheet overhung.

He was adamant that it had to have zero lash ballscrews rather the rack and pinion of his existing table and therefore
he limited the y axis movement to save money on the long screws and rails which would otherwise be required.

Funny thing is that while he did save money by constructing that way but then went out and bought 4 Omron servos and drives,
they are the same company and identical to Yaskawa, and from the local (New Zealand) importers for $3000NZD each, without
considering other brands or sources of supply!! One step forward, two steps back in my book.
