I will not go into greater detail of the code behind the rotary encoder + arduino experiment, as featured articles and great tutorials are available all over the web. Lab Note: RT & Arduino experiment ...

It is based on some assembler code I wrote for a PIC years ago, and relies on polling the current state of the two input pins from a rotary encoder, and comparing these two binary bits with their ...

For most CNC machines with a rotary axis, the A axis is treated as such — a rotary axis. For the Rotomill, [Adam] and [Matt] are generating G Code like it’s a normal Cartesian machine, only ...

[Kent VanderVelden] has come up with an interesting AR system to assist operators who are monitoring CNC lathes. (video, embedded, below) The idea is to first produce a ‘frozen’ video s… ...
