The Tool Sensor Section

The position of the tool sensor and the start position of the probing movement, all values are absolute coordinates, except MAXPROBE, what must be given in relative movement.

[TOOLSENSOR]
X = 10
Y = 10
Z = -20
MAXPROBE =  -20

The Change Position Section

This is not named TOOL_CHANGE_POSITION on purpose - canon uses that name and will interfere otherwise. The position to move the machine before giving the change tool command. All values are in absolute coordinates.

[CHANGE_POSITION]
X = 10
Y = 10
Z = -2
