disk probe calibration issue

[RICHIE RICH]

I am trying to calibrate a disk probe
runs great up to last hit
if i use 21 hits the 21st hit is going to 0,0,0 and crashes
if i use 13 hits the 13th hit is going to 0,0,0, ect.
I am pretty sure i have all the parameters set correctly.
Any ideas

The starting and ending angles for the 'height' need to be a + and - 7 or 10 degrees (something like that). If one of them is still set to 0 (zero) it will try to hit on the top of the tool.

i used 10deg and 80 deg

it still tries to go to 0,0,0, on last hit

You set CALBRATION MODE to USER DEFINED, tell it the number of levels and a + and - angle of 10 and it still wants to go to the top of the sphere?

[RICHIE RICH]

it wants to go to center of sphere

it is moving to 0,0,0 the "core" of the planet if you will

Have you tried setting the prehit and retract to a larger value as well as the CLEARANCE DISTANCE IN Z, maybe it is set to 0, change it to 6" or so.

Try just 12 hits. I believe that PC-DMIS has issues with calibrating disk probes with anything more than 12 hits. I had a similiar issue in the past.
I think its 12 hits....brain isn't working too good today.

5 hits will difinately work. As a last resort.


Hope that helps somewhat....
