Read the size of the working space from GRBL's $130, $131 and $132 parameters. Then on every movement request compare the distance from the current position to the limit and do not allow jogging beyond that distance. This will keep the movement from triggering a limit switch or hitting a hard stop which will cause GRBL to loose its position or the steppers miss steps.

The override codes for spindle, rapid and feedrate parameters are not currently implemented. Allow the user to select an override value and send it to Grbl. Also allow the user a fast reset to nominal value. Indicate clearly on the screen that an override is active when it is set to be outside of its nominal value.

Before starting a probing cycle, ask the user for the direction in which the probe should move. Store this setting in EEPROM for later recall. Suggest using a two step method where:

1. Ask for direction, use jog wheel to select.
2. Confirm start of cycle using encoder button.
