General Mach Discussion / Bit Height Offset

« on: August 14, 2011, 08:35:41 AM »

Hello All,

The newbie once again has a question for all you pros out there.
In setting up the bit height I use a .375 inch roller bearing. I will jog Z up and down until the bearing will just roll under the bit with a very slight amount of resistance and then zero out the axis followed by adding .375 to the DRO. This may not be the best way of setting the bit height, but I have been getting pretty good results.
My question: If and how would one put this .375 measurement into Mach3 to where when I am setting up my bit height all I have to do is zero the Z DRO and the program automatically adds the .375?
I hope I explained this correctly.

Thanks

Mark

Thanks all for the inputs.
I tried my hand for the first time at tinkering around with a screen set.
I added a hot key to one of screen one buttons that did not have a hot key and somehow lost my positive X drive.
Wound up having to reinstall the entire program. One sure needs to be careful.....
Everything is back to normal now and I think I'll do a lot more reading up on what the heck I'm doing.

General Mach Discussion / Turning ON Tool Change and Safe Z Positions

« on: August 11, 2011, 07:13:35 AM »

Hello All,

I have noticed on the settings screen there is an area to input Tool Change Position.
How does one turn this feature on? It would be handy to have the machine move to an easy to reach spot to change tools.
Also, how does one get Safe Z to function too.
I have search through the documentation, videos and within Mach3 itself and have not been able to spot these..
Thanks in advance
