The one thing I will say, is they're far easier to handle if you have accurate homing on the X-axis (Z axis is less critical as you can just bump of the end of the stock).

With mach3 you want to be using the Txxyy format, where xx is the tool position, and yy is the tool offset to use. It's meant for turret setups where you swap tools in each position.
Thanks. I did read through the manual today. So fairly confident I understand although Ill play a bit later and see. I dont have many 12mm tools that are suitable but just 2 will prove the principle.

The machine has proximity sensors, so I think reasonable accurate (hoping).

So T101 is tool 1 using offset 1? Is the offset captured in the tool table?
