“Measure twice, cut once” is great advice in every aspect of fabrication, but perhaps nowhere is it more important than when building a CNC machine. When precision is the name of the game, you need ...

It is amazing how many Arduino programmes for decoding rotary encoders start with something like: “I looked at all the available rotary encoder sketches and none of them met my needs, so I have ...

Linear guides support and control precision linear travel on axes in myriad machine and robotics types for modern automation. In linear-motion applications that are especially demanding, linear ...

The A2K Absolute Optical Encoder from US Digital can be assembled onto existing shaft and bearing assemblies. The encoder reports the shaft angle within a single 360° rotation of a shaft. Last year, ...

An encoder is a device that measures position, and in some configurations, can also measure direction. Rotary encoders measure rotation of a shaft, while linear encoders measure distance traveled. For ...
