After greasing my tool carrousel, my machine is now giving me a 585 alarm and 401. I think the 585 is a custom macro alarm as it is bombing out on the tool change.

it seems to be overshooting on the tool position. A fanuc tech earlier in the year remarked that my spindle didn't have much rigidity when it orientated (M19). I think this is causing the tool change issue as it can't resist the momentum from the newly greased carousel wheel with the poor rigidity when orientating/positioning.

I have a A06B-6059-H003 spindle drive without orientation board. I found the spindle manual B-53425E which I thought was for this drive but the manual doesn't describe the correct board features and seems to be for an analogue AC drive instead of digital.

I think variable resistor RV6 may help but would like advice before I go playing with things.
