Re: [Emc-users] Need a contour finder probe

Hi Gene, The Renishaw-type probe is explained fairly clearly over here: http://www.indoor.flyer.co.uk/probe.htm . The idea is to have three conductive rods, spaced 120 degrees apart, lie on six balls, so you have a proper kinematic seating. Each rod closes the contact between two of these ball

Re: [Emc-users] Need a contour finder probe

Hi I have once evaluated a professional (ca 80'000 $) solution where you can guide the probe by hand. I will try to describe it, how it worked: You had an separate electronic consistent of a 3D probe, an PC with control/measure software and an interface box between control-PC, probe and CN

Re: [Emc-users] Need a contour finder probe

I think that's how I did it, mounted the tubes in my lathe vise and milled the sides of the tubes. There was a bit of hand filing. I just took a glance at digikey's catalog and I think you might want to try the Fairchild parts on page 1984. They have one with a 3.81mm slot. There are some Omron

Dear Gene Thankyou for your kind note. The pont about microswitches is well taken, tho I personally have had no trouble. But when I have a moment I'll set up a test jig using a micrometer spindle, see what I find, and let you know. I think some of the variability might be due t
