Yes but I'm not seeing the correlation between tool setting and probing yet, i'm probably just dense ;)

I have tools mounted - they need measuring in the spindle by the system.
I have a probe mounted - it also needs measuring by the system.

Lets ignore my current height setter - its offline and we are heading to full CNC tool calibration here.

It looks like i need the probe for surfaces PLUS a touch plate for tools?

The machine must be in a known position re Z and C axes before setting tools or no relationship can exist surely?

Don't forget I have what is like a VMC but with the added complexity of being able to move not only the Z axis like a VMC but also the bed/knee unlike a VMC :)

ok now i got you.

These are two different Pairs of shoes.

one is to use the touch probe to get the tool lenght measured automaticly.

the other is to get workpiece things (X/Y/Z surfaces , Center of inner diameter's and os on)

but both can be combined, to get the tool lenght every time you change a tool.

on one of my machines i only use the Routine to measure the tool lenght only after i had to
replace the tool (broken or dull), and not every regular tool Change.
 
anything is possible, just try it.
if you find some mistakes, in my bad bavarian english,they are yours.

Yes that is what i need - only need to measure the tools once when loaded into rack or ATC - the tool table does the rest.

Also want to probe surfaces, XYZ etc

i have all the routines for CSMIO (M31),
only disadvantage the comments are in German,
but this should be the minor Problem.

here a screenshot of my probing screen

Sounds good, thanks, would be interesting to read them.

But do i need TWO systems here - a probe for surfaces AND a plate for tools?

And I think I am correct that I will need to drive the knee to a know position each time I do a probe or tool?

Ah, good so I'm on the right track at least.

Something like this...
http://medw.co.uk/wiki/CNC+Probe

And this...
http://www.yrcnc.com/product/cnc-tool-touch-off-probe/

I have no idea here but these popped up on a search, are there any better (without going super-pro £££££)  :)

i have also no idea about the Quality of These part's.

i buyed mine, figured out the tolerance was below 0,05mm,
and that was good enough for this case.

Dave,
Start somewhere and gradualy add things for probing. You can only fit so much on a screen page so you may
need more than one. The following could be thought of as blocks of a complete probing screen:

Tool setup page - a page to take care of populating the tool table via probing with all that is required to do it.

1. Tool table - be able to manipulate the tool table easily
     - open, save, export, import,reset, back up tool table.
     
2. Probe tools  to populate tool table based on a probe in spindle
    - Probe / set plate for tool touch off
    - Probe direction direction buttons
    - Probe feedrate
   -  probe active
   -  tool number / prev and next for slelection
   - tool offset adjustments for tool table values
   - tool change location

3. Similar to  2 but using the knee, combine with 2,  speperate page..........think about it some

4. Part of screen with jogging control and generic DRO's so no need to jump between pages to accomplish
   whatever task your doing.

Probing routines for different situations. there is no one that satisfies every situation and is done the way you want it to work!
You define what you want and need. There are plenty of examples and there is no right or wrong way
to do it. You are the boss of the machine and not in some enviroment where is needs to be standardied!

Now take it up a notch and add pages or create wizard screen set to take care of  stuff you don't use
every day like the follwoing:

1. The ability to manaully and automaticaly reverse engineer something, so your gathering locations and depending
   on how  the info is gathered you create a drawing of it for use in CAD or CAM.

Sometimes total automation is not the best thing to occur and semi or partialy manual is a much better method.
Different probes, different degrees of accuracy ( quick and ditry has it's place in doing work).
Just depends on how, what, and the end product YOU desire.

I also echo again that:
All tools are related to the master tool but they are related to each other.............
Consider working in Machine Coordinates for any measurement, if you start from a zero location all things are
related to zero!

Must remark that not the sharpest tack in scripting on this end, so , if I can do the above so can you.


Have fun,

RICH
