Probe Cost

2D dxf files would be just fine to me. could you mail them to me (send as private message)

I would like have some drawing specs if possible also (.dxf). How does the probe send information to the computer? I see the three wires but what do they go too.

On/off signal. Mine is a two wires only; some digital ones have a 5V power supply along with the signal wires...

I'll post my drawings on my pages... soon I hope. Specs in this case are based on parts that I had handy; steel balls (bearing), harden rods (drill bit shanks), spring, wires (speaker), plastic leftover from previous jobs for housing (something like UHMW I think) then I bought what I have'nt from that; screws, PCB blank...

I should have most the required materials available to make a probe. I use to rebuild machinery for a ball bearing factory so I have a ton of ball bearings in my tool box.

Hi,

I got the idea how it centers. The ball bearings will not allow the center hub to move in its plane because of the triangular shape. The only way for movement to occur is by touching something and lifting the hub of the bearings. So simple, yet so genious! Thanks Paco for the pics.

Thanks

Sebastian
