Dimensioning Probe Digitization
« on: October 18, 2009, 11:32:26 AM »
I'm loving ,finally getting my digitizing probe working for me. Can any tell me if there's a way to take the G-Code file it generates and make it readable in my CAD package (I have Rhino) so that I can dimension the angle and surface results? Or even an alternative to doing it this way. I've just been using the Digitizing Wizard resident in Mach3. Thanks,Keith

Keith, I'm not sure but there may also be some information in the video probeing board that may help.

Greetings all,
 I too am looking for the solution to taking the digitized file from mach3 and editing it in a cad/cam program. So far anyone who has info isn't saying anything. Some help would be a good thing!

Accutrans 3D at
http://www.cadcamcadcam.com/software-accutrans.aspx is supposed to take the point cloud and make I guess a surface out of it.
After you get a surface then you can use a program like BobCad to create your G-Code.
My question is since you both are asking what to do with the scan data you must have a working probe plugin.
May I ask what plugin you are using?
Thanks.

Thanks for the info Rick. I'll look into that today. I'm using the digitizing 'wizard', that is provided with Mach3 (Art wrote it).

Huh, turns out I bought Accutrans a while ago when I first started getting into this. So I asked them about all this and this was the reply I got:

Change the file extension on your g-code file to ".txt" and in AccuTrans use the
'File -> Open As -> MaxNC Probe" menu command.

AccuTrans is expecting the scan passes to occur at constant Y and the file to start with the G90 code as in this example

G90
M01
G00 Z.2
M03
G00X0.0Y0.0
G01X0.0Y0.0F10.0
Y0.0000Z0.0000
X0.0000Z-0.1599
X0.0146Z-0.1599
X0.0293Z-0.1599

The scan is expected to be for just one side of the object and not a 360 degree scan to do all sides of the object.

Triangles will be created from the point cloud data.

He also added (I use Rhino as my CAD): "If you only want to import the point cloud into Rhino, what file format would you want to use?"

Not really sure what to say to that and if I really want the point cloud per se in Rhino.
I'll give it all a try tomorrow and post the results.-Keith

I've heard that Rhino can load point clouds natively. You also can use MachCloud, which will convert it to an .stl file.

I guess that depends on which Rhino release. I have one of the first releases and it doesn't have that on mine. If Rhino would finally release a Mac version, I would probably upgrade, since I'm an avid Mac user now. Still the first releaase is amazingly good for some things believe it or not. Will check into MachCloud.-Keith
