Craftbot 3 - Build Plate Warped (Straight out of the box)

The Craftbot 3 is a great machine when printing one or two objects on it's large build plate. However, it is IMPOSSIBLE to print say 10 to 15 objects because the mechanical 3 point leveling SUCKS. Not only that, but the heat plate, bottom of the build plate and top of the build plate are not machined FLAT.
Craftbot needs to step it up and release an update (hardware and firmware) where it will have active bed leveling to accommodate for warped surfaces just like a Prusa i3 Mk3.
Maker Muse did a good review of the Craftbot 3 but didn't go far enough in terms of how weak the build leveling is and that it needs to be fixed badly.
Beyond that, the Craftbot 3 output is VERY good with consistent layer height and extrusion.

Have you tried a piece of glass?

I use a glass plate for years on my CraftBot Plus. Using some cheap office binder clips to fix it in place. Works very well for me and i have not had any issues so far.

I'm having exactly the same issue and thought it was a leveling problem which it is not.
