How to store a measured offset value permanently
« on: December 07, 2012, 10:21:40 AM »

I'm going to write a macro or file for ATC. Unlike an ordinary ATC, it
is a box with holding several tools and has a tool height sensor on the box for
checking each tool height everytime the machine head pick it before using it
for machining.

The first tools to face machining a workpiece's surface will care nothing about its
height/lenght. After machining, it is brought to height sensor for probing the reading,
this digizied Z distance (offset value) is read and is as the reference offset between
workpiece surface to sensor surface.

Later on, every other tools' measured tool height from this sensor will be needed
to be substracted or added (depending on the workpiece's surface is above or below it)
from it and acts as tools' z-offset.

Don't know if this procedure is reasonable? what important is, I want this (offset value) can be
permanently stored at some place. As some machining takes long and machine will be
off. Afterwards, when continuing and changing to another tool to machining, this value
are needed. I don't want it to be automatically written in a seperated text document
by VB script program. Is there any place on Mach3 screen to allow for inserting this user
value and will not be erased after power off?

Can somebody help? Thanks,

Create a set of DROs onscreen OR store them as a #var in the range of 500-600.
