Hmm, any chance of a worked example of that method? Just a few lines of what happens....
Took me long enough to get my head round the little bit i have got it round so far
A few comments first:
- When machine coordinates = part coordinates then there are no offsets
- One can create an inialization file / macro to put the machine into a reapeatable state
- One can reference or de-reference axes
- Lathe tooling is more complex than mill tooling,so there are differences, but basics of
how to are still similar.
- Tool 0 has no offsets, is not configurable but can be used to advantage
ie; T#0 and T#1 can be used for the master tool but if you change T#1 then all the other
tool offsets get changed. All tools relate to the master but they also relate to each
other.
- Any touch off and recording of data is only as accurate / repeatable as YOUR machine
and setup.
---------------------------------------------------------------------------------------
Now there are numerous ways to do things, but here are some things to think about which
in the long run will save you time.
1.How do YOU want to work?
2.How automated and to what extent do you want to do things.....now and in the future?
3.If you can get a a screen set which satisfies your needs, buy it / use it as custom
stuff does take time to do.
4.No need to buy expensive stuff when you can accomplish the same simply and accurately
with home brew things. BUT, there is a lot to be learned by reviewing what industry has to
offer and how it's done.
----------------------------------------------------------------------------------------
Simplified example:
Home, referenced location, and tool change location are the same based on a probed
part location or setter using reference tool / Tool #0. KISS! Tool#1 is also the same
reference / master tool and has no offsets.Thus one can see current tool offset in the DRO's.
There are no G92 offsets. Thus any tool offset is based is based on machine move as compared
to the master tool for current probed tool to same location.The axis is probed to a common
surface / plane and touched off automaticaly and also the the current tool offset is put into
the tool table. Moving away to a generic / common location is always known.
SO.....Set / find a reference, probe axis to it, move away for change tool, probe current tool
and continue until tool table is populated.
NOTE:
Not all needs to be as above initial current state, BUT, It all depends on how you want to work.
ie; You could have the tool change location anywhere you want,etc,etc, etc.
What YOUR macro does addresses YOUR machine capabilities, how YOU want to do stuff.
-------------------------------------------------------------------------------------------
So it would seem logical that one look at the big picture and probing macro would find
some location, set/ reset machine state, find and update the tool table. But addtionaly
one may want additonal options like:
TOOL TABLE
- open it
- save it
- export it
- reset it
- import a table
Allow for manual and automated offset adjustment, tool change location, creation changing
of offsets, etc.
But other then tool probing, probing can be used to find locations, create a dxf based on
point data, and all the variations on data manipulation to suite ones need.
Just some thoughts,

working ....took hours.....what a pain and never /ever again. That's why I won't even assist with that junk.
