Automated 3d Laser scanner platform by downeym Jun 10, 2013

Description

This is an automated 3d david scanner I made for 3d scanning. It uses a stepper motor to rotate the object and an RC servo to raster the line laser across the object.

video of the setup in action can be found here:

scanning software : david-laserscanner.com/

the automation software is written in visual basic

a sample scan can be found here: thingiverse.com/thing:102319

I have attached the source code to the automated VB6 program used to automate the scanning process along with an installer. A brief explanation of the software can be found here: youtube.com/watch?v=ChfcFeCMLHA

I am also using com0com virtual null modem cable to communicate with the david scanning software. This allows me to use the same PC for automation and scanning. This can be downloaded here: com0com.sourceforge.net/

i updated the link to another one that should also work fine...

The amazon link for the line laser no longer works, any chance you could post a BoM with device brand & model or update the links on the information section? :)

sounds great! I hope you can post your design when you finish to share with the community...

Instructions

I am using 6mm thumbscrews to secure the base, camera mount, and servo controller mount. a 5mm set screw secured the line laser. Tap these holes.

I am using a 1/2" wooden dowel as the vertical upright.

Why not use an Arduino with a motor shield to control the system?

because I am old and prefer my visual basic tools! :)

Sorry for the request, but could you give me an idea in terms of the costs involved? I love the project, but I'm also on a limited budget. Much appreciated, and thanks for posting your work!

not to be that guy, but i gave you direct links to every part you need to buy. You cant add them up yourself and decide if you can afford it?

Is the automation software already part of David Laserscanner or is obtain separately?

downeym on Jun 16, 2013 said:

I attached the VB code along with a quick video explaining how the code works. Hope it is more clear now.

I just wrote a simple program in Visual Basic. It's not complicated. David scanner software can accept serial port commands to start scanning, copy scanned data to the stitching function, erase data... Etc...

The ssc-32 servo controller also accept serial data. Basically you tell the servo where to move to and how slow it should move there. I have it set for 20 seconds per move so that the David scanning software has enough time to capture the entire surface.

The stepper controller has its own vb component. You set the max speed of the motor, the max acceleration, and then you give it a new position to move to. The motor I am using is 200 steps per revolution.

I would love to see the model quality.

Maddog3189 on Jun 11, 2013 said:

Awesome stuff. Any chance you can upload the model or a picture of the model to see how it all came out?
