I was working with Karl Tinsley on a joystick controlled cnc pendant for Marlin but stopped development when I decided to switch back to Mach3 for my control software. I had written some code to allow joystick jogging and also to use a laser pointer to plot points on a round surface and use them to calculate and jog/set origin to center of the circle. Karl added code to have a variety of push buttons control functions like laser, zero touch plate, etc… I haven’t seen Karl on the forums for a while. Wondering if anymore progress was made on this. The pendant was driven by a seperate arduino nano communicating with the mpcnc mega 2560 over a serial connection.
