So i had an idea similar to this one: [vimeo.com]. Where you have a vertical table cnc mill but i want to implement the Core XY system in this. I am going to use Nema 23 motors and since the table will be moving the XY setup will be relatively lightweight for being a cnc mill. The cutting area will be 400x300mm. Do you guys think that there is any disadvantage to use the Core XY system instead of a regular cartesian belt driven system? I guess it will be affected by gravity the same way so the spindle will fall down if the steppers are unpowered, is there any way around this other then using ball screws or trapezoidals? Do you think the Core XY system will be up for the task?
