Was not a cookie cutter... 2 Z Axis (1st time I saw this approach), Nice use of belts for long runs, X Axis height is using C-Beam from the Y Axis (not the normal plate), Y Axis steppers are in a fixed location. Thanks for the ideas and sharing your knowledge.
Openbuilds 4x8 cnc
I built this cnc using 2 z axis actuators thinking it would minimize deflection and it seems to be very sturdy. I used 2 1500mm c channels for my x axis, 1 1500mm c channel for my y axis, nema 23 stepper motors, dm556 drivers, 2 24v power supplies, smc5-5-n-n controller, 9mm wide belts, and the Hitachi m12vc router. So far it's working very well with a few hiccups. Programming the controller was a learning experience but I'm very happy with it.
