I created this app to send jogging commands to a small CNC machine with a GrblHAL based controller. The app acts as a wireless pendant and sends these jogging commands to an HC-05 Bluetooth module wired in to the controller. The app is able to send jog commands at a user specified speed, for a specific distance, or as a continuous motion command until a STOP signal is sent. Controls the X, Y, and Z axes in the +/- directions.
