Rack Set Up

[Flintstone]

We have two CMM's. Both have the same software. PCDMIS 2019. They are both Brown and Sharp Global machines. One of these has a probe rack already set up with four module ports, and eleven stylus ports. We plan to set up an identical rack for the other machine with identical probe builds. At this point we have the modules and a couple of the probes. We have assembled the rack onto the table. We are following the instructions in the SP25M users guide. We have gotten through step ten ( see attachment ) but we don't understand step eleven. Not sure at all how to "Create a datum coordinate system for the module docking position of the port at the following position: [dat_MOD_port(n)]". We think the (n) is the number of the port. Are we in over our heads? Is this something someone can help us with? Does this have something to do with the probe changer Mount Point dialog box? Perhaps the Probe Changer Port dialog box?
Any suggestions will be appreciated.

Thanks!

That is the Renishaw manual. To set the rack up properly in PC-Dmis you need to follow the help. https://docs-dev.hexagonmi.com/pcdmi...ger&rhsyns=%20

I don't see an attachment.

Sounds like this is an MRS with FCR25 garages setup.

I recommend using the probe rack qualification routine in Pc-Dmis rather than the SP25M users guide. The SP25M guide is written to be software agnostic. The Pc-Dmis probe rack qualification routine provides pretty good step by step instructions.

The instructions are what I posted the link to.

Thanks Guys,

We'll give that a shot.

We are changing tools.

Thanks so much for the help!

Ok,

Now that we have our rack set up and running, is it possible to tweak it's performance by editing values of the ports? We have one stylus that is not wanting to load all of the way in the rack. It might be the little spring loaded receiver thing. It's harder to push the stylus into that port by hand than the rest of the ports. I'm going to make sure there aren't any burrs in that port first, but then we might have to adjust it. It would be nice to twinkle finger in an adjustment rather than recalibrating the whole thing. ( and that might not solve it )

Thanks.

There are tabs across the top, in one of them it shows all of the ports, there is a "+" symbol tick box to the left of each port, that opens the X,Y,Z address of the port. You can make changes there. I had to make a few adjustments in Z to get all of my SM modules to pick up and drop off correctly, but I never hand any issues with the stylus holder configured ports that I recall.

I would first try swapping out the plastic insert in that port.
I would also try assigning a different stylus to that port.

Mostly likely the problem is not the X, Y, Z of the port but rather the size/quality of the insert and/or stylus holder.

We had luck changing out one of the inserts (PA 25-SH). We plan to order a couple extra in case we need them later.

Another question. The CD values under the port tab in the probe changer dialog box, are these the clearance distances in front of the rack? Can we edit these to make room for a big star probe if we need to?

Thanks.

CD = Clearance Distance ; Click on Port1 -> Edit Port Data -> Change the values as needed Before Drop-off and Before Pick-Up
Helps you when you use Star Tips.

Another option, if your star probe isn't always going to be in the same rack, is to set the clearance for the probe itself. In the probe utilities window(for calibrating probes) click on "Setup...". Then in the middle is the Clearance options. The last one is "For tool changer port when probe is loaded:". This will only affect that probe, no matter which port it is assigned to.
