recently i bought new ruby ball tips for my portable romer omega arm. in my nievity i thought that different dia ruby tips could be screwed in and used with exisisting probes e.g using a 5 mm diax10mm in a 6mm dia probe. when i measure it still thinks i have a 6mm dia ball in the probe. can i change anything in pcdimis which recognises that its a 5mm ball in the probe?

don't you calibrate the probes on that machine? the calibration will tell it what the REAL size is.
im fairly new to it and it asks for a sphere to calibrate it on which i dont have. is their any other way of calibrating it?
NOPE, you should have a certified calibration artifact (which is 99.9999999% of the time a sphere). If they don't have one and haven't had one, then all measurements from your shop fall under the SUSPECT heading since the critical features of the measurement process (the probe) has not been calibrated.
There SHOULD be a metalic sphere stuck to a magnet on the side of the ROMER. That is your calibration artifact. If it isn't there you're in deep stuff. It is a required part of the machine and doing probe cals is something that you MUST do each time you start it up.
As my previous post on tip replacement, the probes are "smart"-- they self-identify to the arm what size the ruby ball is, so you cannot put any old tip in the probe--because you can't change the resistor in the probe that tells the arm "this probe has a 5mm ball tip", etc. A new tip must be the exact same size as the old one, and you must recalibrate the tip when you do so. This is so you can "hot swap" probes. So it's the arm that's doing this, not PC-DMIS.
So there's now way to burn new identification of probe dia into the resistor? They do that on DC Torque guns, so adjustments can be made to the torque strengths/angle calcs. No options in the Cimcore Utilities? I agree PCDmis doesn't have anything to do with probe dia for the Romer, but surely they built an option into the Arm's Software?!?!
If your using Cimcore Utilities for your arm, open up C:\Program Files\CIMCORE\WinRDS\armdata and open the file corresponding to the probe you want to change diameter on. The files are named Probe.1,Probe.2,etc. They open with notepad. You should see something similar to the following
There's actually two files that need to be changed. They will both have the same name, but ones under /armdata and the other is in /armdata.s6x. It worked for me changing just one, but the /armdata file is the calibrated value, and the /armdata.s6x looks to be the nominal value. Probably wouldnt hurt to change the PLTH (probe length) if you use a different length probe, but I doubt it will make a difference after you calibrate the new probe.
Awhile back I removed my 6mm ball and replaced it with a 2 mm ball. Now I have a need for the 6mm ball, however use the 2mm ball frequently so I replaced a point probe with the 6mm ball. When I attemp to calibrate this probe it displays that it is probe #3, however my 3mm probe is also probe #3. When I open CIMCORE Arm Utilites with the probe hooked into the romer I get a message stating that Probe XXXXXXX has not been calibrated on this arm. Press yes to calibrate, no to cancel. After pressing yes I get to the point in to calibration to take my points and then it freezes, can't take points or exit the calibration. I am still able to calibrate my other probes, so it must be something with this specific probe.
I was thinking if I could get my arm data opened up and change the probe number so I do not have two #3's it might have fixed my issue...but that itself lead me to my next issue. It appears I do not have an "armdata" folder. (See attached screenshot)
