Gary... um... we're talking about Z, not X/Y...

I think you were reading too fast Lloyd, he started out by describing what to do for Z and then went on to describe x/y.

I guess I should have made a separate paragraph so I don't lose you young guys.

In any case I try not to be close to anything while jogging. That 0.1" jog step can really break stuff quick!

Or hit the button to jog a step, and not realize its it continuous mode. 

Oops.  Sadly put a ding in one of my tool height setters today.

That why I love my 2010 Mach3 screenset with all those probing. Auto zero Z,  X-Y Location, hole center, etc. Easy and accurate...

For those who own Mach3 it's a cats meu!

. I use a round pin of known diameter. Rest one finger on top and roll it back and forth, very sensitive, enter the pin diameter Haven't found a better way yet.

My preferred method also as I have a lifetime supply of 6mm endmills that have suffered a premature demise through no fault of their own.

I modified the jog step list in Mach3 to have only .01 and .001 increments.  .10 is too far, and .0001 is unneeded on a machine with .001 backlash.

How many .0625 - .015 ball end mills do you use.  I use .0625 just about every day, and its a rare time when I get to go a couple days without using a .03125.  I've deep slotted with .026.  Now that's slow. 

When you work with that small stuff for every one you need you buy three just in case.  Sometimes 3 isn't enough.

I've used a 0.0625" ball mill just once, didn't break it so I didn't learn as much as you have! Broken lots of 0.125" ones though.
