Z axis height setter

[cropwell]

I can let you have a macro to set tool height, I use it in conjunction with a brass block.



The block has an acrylic layer bonded on to stop it earthing on the workpiece and the tool has to be earthed (mine has got a good enough earth through the spindle), then I just turn both faces parallel and check with a micrometer exactly what the height is. That goes into the gage block height in the 'Offsets' screen on Mach3. The side of the block has a 4mm hole for a banana plug to connect up to the test probe input on the BoB. Check that the test probe port and pin is set up and that the 'Digitise' indicator comes on when you connect the block to earth.

Then there is a script under the button 'Auto Tool Zero' on the Program Run screen. Fairly straight forward.

I know some people use a fancy screen set, but I am sticking to vanilla Mach3.

Cheers,
