“This project documents the re-purposing of a ‘rescued’ 1980’s IBM 7575 SCARA Robot Arm, into a functional 3D ABS printer. The project features some motor upgrades,  documentation of encoder positioned motor control feedback theory, the interminglings of EMC2, heated workspace construction and a step by step overview of transitioning from 3D stl model to 3D g-coded structure.  The huge reach of the 7575, allows for printing large objects, (roughly ~25″x12″x6.5″ maximum).”
