The ironic thing is Cliff, I just tried the MP12 probe and holder in the machine, and the IR of the OMM isn't reaching the window of the probe.  :bang:

The MP12 is intended for the vertical spindle of a milling machine of course.

All is not lost, as the probe mounting is universal to a few Renishaw probes, and I have another (an LT02S) that has the window pointing in the right direction !






awemawson:
Sometime these 'Gotcha's ' creep up on you unawares. Looking at the two probes side by side it is dead obvious that their windows point in opposite directions, outwards and left for the LT02S for a lathe turret, and upwards (if in a spindle in a mill) for the MP12

I've handled these things numerous times but the fundamental difference never dawned on me.

Oh well, honour redeemed by mounting the LT02s on yesterdays adaptor and I've proved that it works as fitted.
tom osselton:
Glad it worked out! So why the difference in window direction? Or is that dependent on where the receiver sensor is positioned?
awemawson:
The "Wrong" one is intended for the vertical spindle of a milling machine so the window points upwards with the OMM sensor at a highish level out of the muck and bullets.

Theoretically I could have moved my OMM to the roof of the enclosure but in practice the sliding door curves up there and stops that being  a solution.
tom osselton:
Ok that’s what I thought my Son had ours moved from the right side to the left to accommodate the 4th axis on the Haas.
