This version includes limit switches for automatic homing and the same pen holder as the Makelangelo 5.
Some soldering required.
This guide will show all the assembly steps for the Makelangelo 5, which can be purchased - fully assembled and tested - from https://www.marginallyclever.com/product/makelangelo-3-2/
Conclusion
Congratulations! The Makelangelo 3 is now assembled. You will still need a pen holder and upload firmware, both found in separate tutorials.
