We've got 3 Faro Arms & another that I've had access to for about 2 months. Of our arms, two are older "Gold" arms that do not have the 'infinite' range encoders. The other arm & the one I have access to are both Titanium arms.
The two "Gold" arms have only had one encoder go out one of them in 4 years (a few months ago).
The older of the two Titanium arms has had two encoders replaced, then the next time one went out, they replaced the entire arm (completely new arm - serial number & all - not just new sections). Now with the replaced Arm, we've sent it back twice - just boxed it up to send it today - we hadn't had it back a month.
The other Titanium arm I have access to is basically unused except for testing out by programmers - no shop floor techs. It's too new to have had problems and thankfully, it hasn't.
I'm just starting on PCDMIS for our CMM & didn't even realize it was available for Faro Arms. I'm still using Cam2Measure & SoftCheckTools (SoftCheckTools should be named MajorPainIn@$$).
Glad to see our new Arms are as "good" as everyone else's.
