How to get the height information of a work pice.
The machine can be controlled via
- mouse at the user interface inside the virtual joystick control
- external game pad
The control range of the analoge joysticks are divided into 6 segments to get same functionality as the virtual joystick has. Using the same settings, described below. - control via keyboard is not supported up to now.
The idea is to get a continuous movement as long as the joystick is triggered, and to stop directly. With grbl 0.9 it wasn't easy to implement. My solution was to send every 0.5 seconds a command for a short movement - a distance which could be reached almost within 0.5 seconds. To avoid an extra edit box for the feed rate I designed the control above, which offers 5 different speeds for each direction.
