Planar correction requires the PLANAR CORRECTION firmware module.

CCB Z=1 - Set the current position to point x1, y1, z1.
CCB Z=2 - Set the current position to point x2, y2, z2.
CCB Z=3 - Set the current position to point x3, y3, z3.

Set the current xyz position to the values x1, y1, z1 … x3, y3, z3 respectively.

CCB Z=4 - Calculate coefficients for planar correction function. Enable planar correction.
CCB Z=5 - Disable planar correction.

CCB Z=6 - Displays actual planar corrected current Z position as long integer.

Note: WHERE Z displays the target position of Z based on the most recently sent MOVE, MOVEREL, or HERE command.

CCB Z=7 - Re-initialize to zero all planar correction variables including x1, y1, z1 … x3, y3, z3 and planar correction function coefficients. Disable planar correction.

CCB Z=8 - Return the current planar correction state, Z if enabled, G if disabled. MS-2000 firmware v9.54 required

CCB Z=9 - Return the limit check status character. The limit status does not show up on the LCD.

The planar correction index will not move past the stage limits set by the SU and SL commands.

Enable planar correction, check z position, and check if planar correction is enabled.
