New CMM - Zeiss vs Wenzel vs ?? (Any Feedbacks)

The OpenDMIS software in some ways seemed more versatily than Calypso, because you could get in and manually edit paths where needed, but for all I know, Calypso allows that too
One of the advantages of Calypso is that you don't need to do this. If you want to check only a couple items, just highlight the dimensions you are interested in as you would in any other Windows program(ctrl+click) and hit Start - Selected Features. Calypso will create the path from the safety cube and clearance planes. This allows one program to be used to create multiple measurement plans for different purposes as well.

If you do need to do some manual editing of the paths, you can, but it's fairly rare to need to.

Sales was a little iffy at first... but service for Zeiss has been there for me, no question. Never been a hassle, never frustrating, always prompt. Also their forum is really good. Big Fan all around.

Problem with mechanical machines is that if you crash it, a software fix for accuracy is much less expensive than a mechanical fix. Mechanical machines are old technology, new machines are mechanically good, and software perfected.

Follow up after our visit from the Wenzel guys (app engr & sales). They did a great demo of the software, and best part is that I wasn't able to stump them on how to inspect with our niche-market parts. The Wenzel's use all renishaw scales & probes, and the off the shelf availability seems like a plus. The OpenDMIS software in some ways seemed more versatily than Calypso, because you could get in and manually edit paths where needed, but for all I know, Calypso allows that too... I could also run OpenDMIS on our old Mitutoyo CMM as well, but doubt it for Calypso (and the $$$!). Accuracy specs on the Wenzel LH's is actually better than the Zeiss by 20 millionths, even with the passive scanning head, and I like the idea of an articulating probe where I don't have to come up w/ crazy star probes. Their big (marketing?) push is that the machine has all granite axis, lapped very accurately, and don't need crazy error compensation maps to give good numbers, vs other being made less expensively w/ extrusions & error mapping... On some forum there was a thread about CMM accuracy, and the person kept checking the same part over several hours, and would find the XYZ location would drift as the HVAC would kick on and off. All said and done, the machine would have an extra 100mm of Z, lose 100mm of Y travel, and cost about the same.

We've been talking with one of our customers that's a Zeiss shop, and what will probably push us over the edge is that they could provide programs & support as needed, and the possibility of more business because we can provide data to them in the format they want...

Wenzel CMM Service and Support Issues in USA

My advise is to stay well away from a Wenzel CMM. My previous company purchased one and service and support became a nightmare. Before considering ask for the list of all customers in your area and call to get their experiences. Ours was a disaster.... Machine generally OK but support!!!
