I left my job for 3 months & they talked me into returning. While I was gone, they bought a new CMM. We originally ran PCDMIS 3.7MR2. They upgraded to PCDMIS 2023. They tried to run my 3.7 MR2 programs & were told they would not run; they were told to install PCDMIS 2015 & the programs would then run. The issue I am having is the old probe files had a RENISHAWPH10MQ head & the new CMM has a Hexagon probe head. When I create a new probe file with the Hexagon head & only add a A0,B0 angle the probe sometime takes all 9 points as it should, sometimes it takes 3 points they goes off into the X+, One time it went in in a circular motion & hit the surface plate. The probe is doing things that make absolutely zero sense. I know it's a long shot, but does anyone have any input??
When I take the manual hit on the sphere on my two new machines (18mos and 12 mos old), IF I don't have the turtle button depressed on the jog box, SOMETIMES I have errors.
I attribute this to being that the machine isn't expecting a hit so it doesn't stop the machine with the normal speed and repeatability that the machine senses contact on the stylus when the turtle is active on the jog box.
This would comp the point wrong.
Sometimes that wrong is off a couple thousandths and the first four hits resolve a sphere sufficiently close to correct, so the machine calibrates the probe position accurately.
Sometimes the wrong compensation is off so that the sphere is solved very wrong. When this happens, the machine tries to touch the sphere in out space.
Never been so far off it has gone near the plate, but I could see that if it was an A100 position.
When the turtle is selected on the jog box, I have never (knock on wood) had an issue with the stylus missing the sphere during calibration.
Is it possible you don't have the turtle on when you take your manual hit?
None of this should mean don't use a master probe, I'm firmly of the opinion that it is best practice, whether or not PcDmis mandates you do it.
if its a scanning head/module you should take a minimum of 13 hits. Pretty sure any thing less you get funky errors and it wont calibrate properly.
glad you figured it out tho!
