XXT angle after probe change

[[Ze...]]

Hello everyone,

What determines what angle the XXT head chooses to rotate to after a rack probe change during a program run? Mine is rotating twice. Once to what I think might be the last angle it used and then to the angle of the next feature in the program. I'd like it to just rotate to the angle of the next feature it's going to measure if that's possible.

I ran into that issue years ago and I seem to recall this being tied to the last calibrated position of the probe in question.

Thanks for the reply, Don. I'll change it to Standard and see if that fixes it.

Hmm. Still does the same thing. It seems like it rotates to whatever the last stylus angle that was calibrated and then rotates again to the angle of the feature it's going to measure. I must be missing something.

My apologies Zen, I may have worded that incorrectly in my first response, but yes I think you are on the right track. Calypso keeps that last calibrated position in memory and then rotates to it once the probe is picked up from the rack (I think).

Are you using Resources>Utilities>Probing system qualification for the angles on your probe? I believe you can re-arrange the order of the qualification angles to where A0B0 would be the last one selected. 

Or

Another guess would be that it may be tied to the last "qualify passive" position as opposed to a "geometry re-qualification" position. Maybe give both a shot if you have a chance.

Fingers crossed!

It is set by whatever is the stylus active inside the of Probing System Qualification dialog when it is closed. Change it to your #1 stylus (typically your 0/0), then close the dialog. It should set it to that one now. 

The only one this doesn't work on is the MasterProbe.

As Richard says: Open the Probe Qualifications window. There, you will find a drop-down menu where you can select the probe orientation. When you close the window, this orientation becomes the one used during the probe change. In my case, for example, I have selected orientation A90 B0—that is, the one from the rack. This ensures that the first rotation corresponds to the first programmed feature.

! Glad to know that some of us remember how to address some of Calypso's quirky nuances 🤣

The "OK" button int he probe qual window sets the "Favorite" stylus, for lack of a better term, to the currently active stylus #/orientation. 

Always be weary when selecting if you are using a rotating head to ensure you don't end up with a collision with your probe rack. If you have it going to a Y+ orientation right out of the rack you could rotate directly into the probe rack that would not be cool.

Thanks everyone for the help. Much appreciated! 

I got everything going. Here's some information in case anybody else is setting up a rack for the XXT in the future. 

The plates can only store in the rack in one orientation with the 2 gold connectors being at the back of the probe pocket. With the rack being at the end of the machine in Y+ the XXT angle is A90B0 to store the probe. I actually didn't even have that angle/orientation as an option for my probes, so I added it to each of my probe calibrations. Then you just select A90B0 as your angle to go to after calibration. Since it's already at that orientation after it picks up the probe, it directly rotates to the angle of the feature being measured next. 

If your rack is mounted on the side of the machine, you would just change you're angle after calibration to whatever it uses to access the rack.
