Master Probe

Do you reset the tips for the Master probe for machine homes??

No !

As Matt says - the Master *should* be reset, for the others there's normally no need. My addendum would be: If you for some reason don't use a Master probe for locating the sphere, you should at least reset the probe you *do* use.

Im sure since I'm not having a problem I got everything correct, but I need to learn the lingo of master probe and resetting the master probe.

MASTER PROBE is more a concept than a 'real thing' you can point to. When using rack(s) it is (generally) the probe in "slot 1", "rack 1". What makes it 'master' is that it is THE PROBE you use to 'find' the qual tool EVERY TIME. As for resetting it, that is simply an option available in the probe utility window when you go to calibrate. It simple sets that probe FILE back to math-perfect values (from the definitions in the probe.dat file). The 'master' probe A0B0 should 'never' show any X, Y or Z deviations.

To see what "master" looks like, you can build a new probe file, then calibrate it, and tell it YES the tool has moved, the A0B0 is what you use to 'find' the location with your single hit on top. It will then calibrate that and all the other angles in the file. When you look at the results, A0B0 will ONLY show a diameter deviation, the rest will show X, Y, Z, & D deviations from the math-perfect values. If you then use that probe to find the tool every time, the A0B0 will stay the same (except D) while all the others you calibrate will show some deviations in the XYZ values. This is what 'defines' the master probe.

If, at a later time, you load up that "master probe" and calibrate A0B0 and tell it NO, you will see some small amount of XYZ deviation from math-perfect, even if you have NOT moved the tool since you 'found' it since no machine/probe/tool is perfect.

Just went to my 1st file of Rack 1 Tool 1 that I use as the common tool (master) x 4 different sphere angles to calibrate the all my sets and the Theo's are a all 0's but the Meas's is not. Does this look correct

Meas offsets = theo only when you answer "Yes, the sphere moved" and select reset to theo.
In other cases, the offsets are calculating from the last time when you answered "Yes"...

Hi, posting in an old thread but I'm trying to find the info, still very new.

If I moved the calibration sphere, and then calibrated a new tip (NOT the master). What would be the process of correcting this?

Thanks,

If you've answered YES to "has sphere moved...yada, yada" the probe it had active when you answered YES is your new 'Master Probe'. Probably not what you want.

Yeah, that's what I did.. didn't know better at the time. So to correct this do I do "sphere has moved" calibration with the original master probe, and then re-calibrate all other tips afterwards?

dinoblaha - yes
