Good evening all

First thanks to everyone for taking the time to respond on my past posts. I greatly appreciate it.

Question: For my New Zeiss Spectrum, RDS Passive Probe, I purchased and installed a new 100L x 3mm TL3 star stylus and cannot get below .0005mm S values on my +Y and +X stylus. A Zeiss technician came by, checked for loose parts on the pulleys, bushings internally and didn't find anything. We re located my reference sphere using the menu tool that tells Calypso exactly which direction and distance the reference sphere is facing, with no luck.

I tried:

Cleaning the reference sphere with denatured ISO

Cleaning and re tightening the stylus assembly

Switching out individual styli

Restarted system.

And I'm still unable to obtain S values below .0005mm on those two styli. I'm talking about initial qualification as Im adding new styli to my system

Any ideas? Is that acceptable for a star probe that large? Should I be hearing ANY squeaking when the stylus scans the sphere?

I ask because I've cleaned EVERYTHING and still can't get rid of minor squeaking when doing qualifications. I assumed that noise will introduce micro vibrations....but the Zeiss technician said that it's not concerning (the squeaking contact noise when the stylus touches the reference sphere).

FYI I'm using 100% proving dynamics and Standard probe characteristics. Running at full speed. Results were worse when running at turtle speed. Advice..... affirmation, anything is appreciated. My other styli are able to produce values in the .00002mm to .0001mm range consistently.

Hello all

As the title states, is that normal at all? This is within a small, quiet mini metrology lab with a new Zeiss CMM, SMC refrigerated air dryer and Tsunami Oil Separator system. I can't isolate where it's coming from either than MAYBE the SMC dryer.

Very faint, and no pressure drops.

Thank you all

Hello all,

I want to tell all of you thank you for taking the time to reply on my past posts regarding the hurdles I've encountered on bringing our new Zeiss CMM online. I've commissioned numerous vision systems and have overseen CMM retro fits, and oversaw the commissioning of a Zeiss Metrotom at a medical device manufacturer, but this is the first brand new CMM that I've been responsible for commissioning.

For context, my company has a splintered group of 6 global metrology labs that are competent, but lack cohesion in terms of equipment selection, standardized approach to dimensional inspection, and sharing of resources. My role is tasked with uniting all of our sites into one focused, singular, metrology resource. Sharing knowledge, standardized equipment and software, effective utilization of each site's unique areas of expertise. Aside from launching a metrology community forum, my first task was to establish a new metrology lab at my current site, hence my targeted questions about Calypso.

Anyways, my new Tsunami 3 stage Oil Separator came in today. Looking forward to having it installed this week. Once I get everything installed I'll share.

Thank you again!

Hello all,

Would like your opinion on this advice I was given. I'm creating a measurement program on a long work piece with vertical slots all along the entire length of the part. I'm performing 2D Cartesian Distance Characteristics on each slot.

I was told that as a best practice, when measuring 2D lines and of you're trying to obtain Distance results between 2D lines, to always enable Projection and switch to Base Alignment to project each 2D line onto your Datum Plane.

Is this required, the projection step?

I thought Caliper and Cartesian Distance purposely allows you to negate Z axis variations when performing distance Characteristics.

Thank you all!

Hello all,

Wanting to get everyone's thoughts who have owned a Zeiss CMM, especially within the last few years. Since installation we've encountered insufficient air pressure error events on our system. Zeiss came out, stated it was out facility air pressure being unreliable. We have a third party service provider from Atlas air compressor perform a facility usage study over a 2 week period and they determined that our CMM air dryer by SMC is getting a steady supply of 120 PSI, which is above the 5 BAR Minimum requirement.

Question: what should the SMC air dryer regulator be set too? There's also a FESCO pressure display behind the CMM but I don't know if that's a regulator or just a display. We were able to resolve the issue by turning up the SMC air pressure on the regulator to 80 PSI, but we're concerned that we're masking the problem and that there's an air pressure leak within the CMM.

Also, is this normal on a brand new CMM? Z axis column residue?

Thank you all in advance

Hello all, hope all is well. As the title states, when I went to locate my reference sphere to requalify stylus, I got an error that said the Master probe is .012D mm off in weight.

I then wanted to run a fitting execution using my master probe, on the reference sphere and the RDS body nudged the sphere body during a side scan Plus X Direction.

This is a brand new Spectrum CMM. Maybe the setup technician didn't locate the groove location for the RDS? ANY IDEAS on what's going on for either instance (RDS collision during fitting and .012d mm difference in master probe weight)

Thank you in advance
