Is this digitizing done in a new function of Mach ?
Tell us about the process and the probe you used, etc.

Hi Benny:

 I was a bit brief wasnt I? :)

  This was my test of th enew 3dProbing plugin. Its included in the latest versions. To use it, just turn it on in config/plugins, then restart. A new menu item "3d probing" will appear.
When you select it, you must have zeroed at the front left of your surface, doesnt matter where Z is, but it shoudl be 0 or less. Set a width and length of the surface, and a depth
for maximum probe stroke. The clearance shoudl be 1/5 of full probe deflection horizontally or less. .1mm is used above, this is th epullout distance on a collision. The point cloud above was made in
6 hours and comprises 65000 points or so. The completed point cloud was 95000 in 8 hours.

  This is reported now to be up to 10 times faster than the old methods of probing in MAch3, thats a huge increase. Very easy to run, very nice poitn cloud output. Im kinda pleased..

Ok cool, Have you given any more thought on a offsets edge finding probe plug in? I am trying to improve the accuracy of the 0,0 process. It sure would be nice to be able to just enter a probe diameter, and then jog into the edges and set the g54 or others.

As usual thanks for the awesome software!

Probe design this was based on an idea I got from http://www.indoor.flyer.co.uk/probe.htm I have used this lots of times to good effect, although I have since purchased at auction a Renishaw probe.
The attached jpg’s depict my version this will scan to a resolution of 0.2mm, the model is in Solidworks if any one requires this let me know, if enough are interest I am willing to convert the components to IGES or what ever format is preferable and possibly produce some Dimensioned drawings, the body is made form Aluminium, the hub from Engineering Nylon, the pins are 3mm silver steel, the Balls are 5mm, the probe tip I made from a Carbide Burr, others parts from the scrap bin, hope this helps.

Shaun your pics make it hard to see the detail around the balls / switching area.

I know how they work. Looked at the probe site and have seen others.

Just curious how you have done the ball retention and pysical part of the circuit.

Great drawings by the way.

Here are the files in Solidworks format, IGES, I have also included a Solidworks Viewer file for people who dont have this software, and a brief notes file IGES files can be pulled into most Cad packages.

Hope this is of help.
