The frame is built with 60x30 aluminum frames. We chose to level the bed with a real 3 point leveling mechanism, 3 stepper motors, ball bearings and linear motion guide rails (mgn12h).
For the 3 point leveling, each connection point sits on a ball to slide to the correct position during leveling and warm up.
The electronics are mainly stored in the back to act as an electronics control enclosure.
