Hello everyone,

I have a problem modifying the spindle indexing speed setting on my Fanuc,
I use a renishaw probe with an eccentric ball, which gives it an unbalance. Sometimes when indexing for probing, in M19Sxxx, the spindle indexes quickly, making a few turns before finding its position, which triggers the probe.
I've tried to correct the problem by activating/deactivating the probe between each positioning, but this solution is not good because I have many points to probe, so I don't think it's good for the probe and it causes latency in my program.

I searched the machine parameters for a Fanuc 31i, adjusting parameter 3732: The spindle speed during spindle orientation or the spindle motor speed during spindle gear shift. But I don't see any modification on the indexing speed whatever the value entered 0, 60, 100, ... 5000.
Also no modification by changing the #1 of 3705 which was initially at 1.
Are there any other parameters that could influence the rotation speed during indexing?


thanks for your help!

Alex
