Hi Dave,
I still haven't gotten my head around how the values for probe length,
workpiece surface offset from machine home and toolsetter height from mill
table are all handled. Every time I look at the code my head starts to spin.
At the moment I have screwed up enough of the psng code that nothing works
right. And I don't want to install the original because of the one bug that
shattered my first probe.
And that bug may well be the one fixed by 2.9.0, see my previous msg.
Figuring this all out is on my list of 42 projects...

When it comes to probes I think in terms of prototyping something that is
cheap and disposable . Did this years ago Round ended shafts at 120
degrees sitting in brass 60 degree cones. Connect the brass cones in series.
Epoxy to plate isolated by a nylon washer. Probe drives the three shafts.
Repeatable to about 0.0001� in all three axes.. Don�t think anyone else
thought it was a good idea or maybe they just had more $$. Think I still have
it sitting on the shelf.
Of course YMMV. Once you get the probing software solid then get brave
and put whatever you want on as a probe.

Hi Chris,
First place for me to spend money is retrofitting ball screws to replace the
ACME screws after I get the power draw bar working the way I want. Then
I'll invest in a monitor with touch screen and take a look at other user
interfaces. For now other than wanting SAMBA on the 2.8.1 I have no real
reason to update the PC/OS. It works fine the way it is.
The operator is another thing entirely. Which is why I have extra probe
tips and the broken shards of the first probe.

If you are adventurous qtvcp has a probe screen based on vers probe.
Should
be able to embed it into AXIS
