When using the Touch Probe what defines the XY zero?
As per the heading - when you use the Touch Probe which part of the router bit is set to zero for the XY axes?
For example: if I am using a 19mm square end cutter, is zero set to the edge of the cutter or the centre?
Secondary question: is there a limit to the size of cutter (diameter) that can be used with the Touch Probe?
Is this a good question?
