In the Mach3 directory.

But that is just an air motor not an IC.

THe basic wizard is VERY simple you tell it the width and length of the scan. The max depth of Z to scan. Then add in the stepovers for X and Y (Resolution) and then the Wizard will generate a Gcode File that does all the probing work.

At the start of the Program RUN it asks for a file name to save to. AND at teh completion of the run it closes and saves the file.

THAT process will generate a POINTS file of the scan in XYZ format. Then I woul duse MachMesh to convert that into a STL or mesh file. Then use your favorite Mesh to do what ever.

I think I got the order right, (;-) TP

I really like the INFO please keep the lectures coming. Kinda reminds me of some of Arts lectures we got from time to time.

Art wrote a plugin to do video/laser probing with a $30 laser pointer . AND a point cloud generator to go with it. May be more of what you are looking for.

Look Here  http://www.machsupport.com/forum/index.php/board,67.0.html

Hope that helps, (;-) TP

General Mach Discussion / Re: How to reverse axis direction ?

« on: December 04, 2011, 04:13:39 PM »

I allways WIRE the drives for proper axis directions with a standard Mach3 configuration.

In Checking the axis movements

X+ moves the Toolbit to the right side of the table
Y+ moves the toolbit to the back of the table
Z + move thetooltip up away from the table

Just a thought, (;-) TP

YEP strange indeed. IF you bump the look ahead up to 200 you will never see the rotated DROs they just stay black all the time. I thought teh Look ahead was only for CV. DID not know it would effect this as well

That is a new one to add to the Mach3, stranger than true book.

3d machining reliefs  with micro detail is NOT one of MACH3s strong features. The micro segmented Gcode causes problems with Mach being able to keep up and provide smooth machining.

IF you can reduce the total NODE count(micro moves) on the Gcode it will help a great deal.

Sometimes that stall is just teh machine doing a LOT of micro moves that do not contain much movement. Mach is processing a ton of lines but the results in not much actual movement.

Where do you have the look ahead set to?  200 lines seems to work well here. MORE may work better in your case.

Just a thought, (;-) TP

Like I said before it can be a very time consuming proceedure.  ANd to get an entire 3d shape of an object you may have to do it in 4th axis mode where you can get all the profiles. OR at least scan all 6 sides one at a time. You may want to set up a fixture to rotate the part without having to do multiple setups each time.

Really depends on the size and shape of the object.

Have you looked into laser scanning with Mach3
