CNC Mounts and 4th Axis

This series of projects involved making mounting hardware for my desktop 3080 3-axis hobby CNC. I designed parts to mount both flat objects and round pipes. I made custom screw knobs by epoxying nuts into 3D printed knobs and cutting sections of 10-24 allthread for the screw posts. I also attemped to make a 4th axis for the machine so I could do more complicated milling operations on sections of tubing and wooden dowels. This worked conceptually, however 2 major problems arose. First, the Arduino shield I was using to control the 4-pin stepper motor did not have sufficient power out put to drive it properly, and second, I could not find a practical way to integrate the stepper motor into the controller that was running the gcode files, since the off the shelf control board was designed for 3 axes only.
