[1.2.10] IBM 7575 Arm Development
[In
Progress]
| What? Aquired an IBM 7575 Robotic arm, sans controller. Its awesome, but far from operational. The following page documents building controllers and feedback systems to get the arm connected via parallel to Linux CNC (EMC2) There are two thetas and one z axis, all of which will be driven by EMC2 for the purposes of small scale model milling |
