I bought a rotational axis for my CNC with a 4 jaws chuck. I intend to use this as both a 4th axis on my CNC, or as an independent lathe. I know, it will be a very primitive lathe, but I intend to try it out anyway. To get the lathe function I had to design a control box. This is based on an Arduino Uno module with a 2x16 lines LCD. It is a very simple design, but acceleration and deceleration is also implemented, as well as rotation direction, and a possibility to select acceleration in 7 steps. The chuck rotation can be adjusted between zero and 380 RPM, which is the maximum. I hope you will enjoy watching this video for more details.
