laser scanner for mechmate??
Hi All,
I have several antique rossets I need to cut (all hand carved) and am wondering if anyone has played with a laser scanned mounted to a MM that can scan and send back info to a program thus creating a 3Dcut file. This a new world for me and I am not afraid to experiment, but am not trying to recreate the wheel if it already exist. Any ideas? Al |
Yes, yes I have - but it's pricey.
The more cost effective solution is a probe attached to your spindle using the "probe" input on your bob. Many MM users utilize this port as the auto Z-zero routine. If the object your trying to duplicate is not to complex, then probing and storing the cloud data is a very robust solution. The probe can be made/or purchased for under a few hundred dollars plus the cloud resolution software. The scanning is simple, but requires you to make up a version of the scanner from either a store bought solution or one-of-the-hundreds open source varients available. These scanner solutions require a lot of "post production" after the part is scanned to get it into usable form to replicate the object. Again, not to scare you, it's all very obtainable - but it will require you to invest in the knowledge and time behind either technology. this is an example of an affordable, passive, "high" resolution probe: http://www.tormach.com/product_tts_passive_probe.html |

Hi Al, I have a 3D scanner if you would like to make a copy of one of them and send it to me, I could scan it and send you a file to try, Leonard

Thank you both for the input.
I was thinking of something reletivly simple and I am using auto zero through my BOB. My thoughts were: To be able to mount laser in by spindle say in a .25" collet to maintain repetability between changes By using a very narrow beam laser to keep focus on a object depth at a the specific location of the beam. We can program the MM on a "flat defined" path at a known speed and track using our existing programing. Feeding the laser output and the location from Mech3 to a program, not sure what one may be Excel, to plot the points at the appropiate locations. Then,with this infomation create a 3Dcut file. Input please Thank you Al |
Have you seen this thread: ?
Laser scanning using a distance-sensing laser |

This works...I have done it. You would only need to build a file in Mach for the pattern movement of the laser. This was actually the reason why I put the laser (crosshair) mount on MM #5 so I only had to add the camera when needed to scan. |
The new version of David also work with Structured light (projector ) .It is much faster ,and you dont need the calibration pannel once it is calibrate . Also no moving parts.

Sorry Gerald I did not see that thread.
It was helpful, but it seams to have died may need new life. I do have some ideas and will post after a little more experimenting feel free to move this thread there. Al |
Why mount a sscanner on MM? If you can live with 1mm resolution; With ReConstructMe, You can turn a Kinect into a 3D scanner.
