Here's what I used last time, to investigate how the Centroid touch off features worked. Perhaps there is some intermediate scheme that I can use to mount the probe. Removing the upright from this mag base looks like a good starting point:
Fits nicely, drill didn't break and a bit of Loctite is ideal for bonding it to the shaft. If I want to replace it, I can simply heat it up with the blowlamp.
Good, so let's give it a whirl. With parameters #281 & #282 set to 9.525mm (aka 3/8") and the "safety clearance" distance reduced to 5mm, we should be good to go.
Here's what I get when I run the Z and X touchoff 3 times (telling it the tool number has changed between events). The offsets seem to vary by ~6um or so. This may be a best case result of course but at least it isn't instantly disappointing.
Let's mount a few different tools in the turret. Then I can touch them off and see what happens when I change tools with the turret and tell the machine to go to the same position in X and Z.
I will need to issue G43 after each tool change presumably, as indexing the tool doesn't in itself activate the appropriate offset. That's something else to familiarise myself with.
It's early days yet but it seems you don't need a G43 for the lathe, just T0202 etc, to load tool #2 and apply offset #2.
