It is indeed a long list.
Where in the world is this table going to be built?
I noticed RS485 specified for servos which is not suitable.
I share others concerns about gantry weight but don't know table size.
I have built complete plasma controllers that were shipped to the customer previously and selected motors and gearboxes etc.
