Hi Tom,

I've only got three axis on both my mill and cnc router so for now anyway I'm happy with a 2.5 D scan. Any undercuts and the finished product won't come out of the mold. (I'm using simple one piece molds)

I don't think I need really high resolution for most of the work I'm doing.   I mm would be more the enough I would think. Basically If I can scan a living person and get a life-like 2.5D scan that I can machine into a mannequin mold I'm there!

I use the negative mold to produce pieces like this..

Hi Eero,

Yes, scanning a live person. not a cast.  I'm looking to machine a "mannequin" from the scan of a warm body.  I had no idea Art and Tom's scanner plug's would require that much time.

I've looked at the David system and am undecided..  I need more convincing that I'd have a working instrument before I'd spend the money on the software and hardware.  Most all of the examples I've seen scanned are miniature statues etc...

Good luck with your musical instruments, sounds very intriguing!

Best, Lawrence

H Tom,

First I just want to make sure everyone understands I am totally behind the develpment of technology on a grassroots level as you have so well pioneered. I hope the title of this subject wasn't taken to belittle yours or anyone else s efforts. 

OK, that said,

When making a scan, cast, etc or a human form it is important that the model be posed in the same fashion as the final piece will be displayed.  This it true with the human face and perhaps more so with the female torso.  Gravity effects a body and the subtle changes in the geometry will be appartent in the finished sculpture if it was not cast in the same postition.

I'm thinking of constructing a lightweight machine  probably belt driven to scan the human subject. The model would be in most cases standing so the machine would resemble a mill on its end.

Does this make sense?

Best. Lawrence

Keep up the great work Tom!

I too am looking to collect accurate date as far as shape is concerned. I'm a sculpter and work in the human form. Presently I take a cast from a live body with plaster and other materials and produce a usable mold much the way it was done thousands of years ago.


I have a couple of three axis mills I've built over the years and I've build a pretty good touch probe to go with it.

My life would get a lot less complicated if instead of smearing a model with plaster and such for more then an hour or two at a time I could sweep then with a laser and essentially machine a body-double from foam in a very short time. An hour modeling session could yield a dozen scans.  An added plus to the model is that no one has to touch them or get messy stuff stuck to their boobies. (pretty clear advantages here, from the models perspective anyway)

I see a lot of OK scans of kick knacks and such but seriously it wouldn't be too hard to make a mold from a plastic statue.

Like they say of kittens and cats, Kittens are one thing, cats are a whole different ballgame! Such is the difference between scanning a miniature garden troll and a living human being.

I think we'd all agree that a good working laser 3d probe would be an invaluable tool.  There are some commercially available units out there that seem to do a fine job but at a high price.

I applaud the efforts here towards getting a functioning tool.

My question is this. At this point in the development has anybody been able to actually scan an object and end up with a usable tool path?

Has anyone actually milled a duplicate of the item scanned with satisfactory results?

Again I think the laser scanning plug- ins are very cool but are they a useful too at this stage?

What is Scan 3D plugin?

Thanks

I've been watching the probing posts for a while and kudos to those who are pioneering the efforts here I have a few questions.


I'm looking to scan a living human body. From the scan I need to get a usable file I can machine into something useful. (think of machining a mannequin from foam)

I don't need resolution to see fingerprints and the like but would like to capture the basic curves of the body.

Is this do-able with the video probing software that is currently being developed as a Mach plugin?

Thanks!

General Mach Discussion / Re: Probing Plug-in
« on: August 09, 2009, 12:41:40 PM »
OK, I downloaded the older version of Mach 3 and got it installed. Then downloaded the plug-in.  Normally double clicking the plug-in will install it. Not this time.

Seems the older version of Mach 3 doesn't know what to do with a plug in file so it doesn't install.

I sure wish Art would throw us a bone here. I'm really thrilled with mach for running my mill laser and router but unless I can get this probing plug-in running soon I'm going to have to find some other software.

General Mach Discussion / Probing Plug-in

Has anybody had any success with the probing plug in (not the wizard)?

After setting the parameters and attempting to start the probing routine I get a message

"Previous SEQ not yet complete"

If I hit "OK" the machine moves a bit and again "previous SEQ not yet complete"

Anyone?

Thanks.

Mach SDK plugin questions and answers. / Probing add-on does not work
« on: August 01, 2009, 06:23:50 PM »
I've tried for a couple of days now to get the Add-on

A couple of issues.

Once I put in the required values and try to run a probing routine I get the check probe dialog box and them when I proceed I get a message "previous SEQ not yet complete."

you can click on OK all day and it won't go away.

Tried this on three different computers, same result.

I'm using the latest version of Mach 3 (not the beta)
Tried both Windoes 2000 and xp,
I'm using the add-on, not the wizard. (wizard was good but primitive and very slow)


Any suggestions?

Has anybody had success with this?

Larry
