Topic: Atlas 3D kit enclosure mods

Having been playing with my scanner for a while and trying to get the best out of it, I have come up with a few mods which I feel may be of interest to others.

I have changed the supplied lasers to focusable ones which imo has helped with the scans due to the finer lines achievable, and also connected turnbuckles with ball links/linkage balls as used on RC helicopters to position the laser more accurately (the turnbuckles have opposite threads each end and therefore move the arm in or out as required). This stops any movement caused when trying to tighten up the positioning bolts as the turnbuckle maintains the required position.

In addition, I have printed side supports for the camera mounting board together with braces front and rear which keeps the camera board rigid and has stopped the slight flexing I was getting originally.

Should anyone wish to make copies, I can provide the STL files.

Re: Atlas 3D kit enclosure mods

I like it.  I have been trying to think of a solid way to make precise adjustments to the lasers.  I have lots of turnbuckles from my RC helicopters unfortunately I have the printed enclosure.  I would like the STL files so I can adapt your method to my scanner.  Thanks,

Bob

Re: Atlas 3D kit enclosure mods

where did you buy the lasers with focus? and do they just replace originals with no mods needed?

I have the printed enclosure also but finer laser lines is all I need

Any chance of a picture of the camera mounting board?

I purchased them off that well known auction site ( item number: 111609050407) - 650nm 5mw Red Laser line Module HLM1230 IIIa adjustable focus.

I got mine from a UK supplier, but I'm sure you can get them in the States or from HK etc.

You will have to make new Laser Holders as they are 12mm in diameter as opposed to 9mm with the supplied units.

I may not have explained myself fully oliver; they are the green items either side of the main panel which supports the camera board and lasers.
You can see the braces either side of the upright panel, together with the front brace in my previous picture.

I have now added a side view so you can see how it attaches to a bottom bolt, slips over the edge of the upright panel with stops which prevent it moving from a right angle with the main platform. Two braces front and rear keep it in position.

Bob, I tried to email you but don't know if it got through!

I have attached a RAR file which contains the STL files and also 123D files so you can tinker with them if you want.

I didn't see the email, but I will get the files from here when I get to my home computer. Thanks a lot.

Re: Atlas 3D kit enclosure mods

OK anybody here good at resizing STL files that could make the enclosure kit right and left laser mounts fit the 12mm Dia Barrel?

Re: Atlas 3D kit enclosure mods

I downloaded 123D to see if I can modify the laser holders to the 9mm stock laser size.  I didn't see the STL files for the laser holders in the rar file.  Did I miss them or are they left out?  Thanks,

Bob

Sorry Bob, missed them out whilst I was adding files to the RAR package sad

Here they are!

Re: Atlas 3D kit enclosure mods

Thanks. I'm pretty good using Blender to modify STL files so that will be easier for me to adjust them to 9mm. Much appreciated.

Re: Atlas 3D kit enclosure mods

No they are 12mm in the files. I want to use the mounts with the standard 9mm lasers that come with the kit for now.

Re: Atlas 3D kit enclosure mods

oh, thought you said you have the printed enclosure like me? the parts for the acrylic enclosure are different from the printed version. I thought you where remaking the STL files to use the larger adjustable lasers on the Printed version.

Re: Atlas 3D kit enclosure mods

I do have the printed enclosure, but it looks to me like the laser holders can be adapted for use on our printed enclosures with the stock lasers.  I would like to someday also upgrade the lasers but time is limited and lately the printer has been taking up most of it.

Re: Atlas 3D kit enclosure mods

Like yourself, I have experienced frustration with minor movements of the structure over time and temperature, and sometimes just as a result of moving the cables from the Rpi.  Have not gone as far as you over the mods at this stage, but I have printed a crossbar which stiffens up across the laser arms, just below the camera position.  As a bonus, it carries an LED light strip for frontal illumination of the object.  Next step will be to support the camera from this bar in order to better link camera to laser position.

Have been thinking about adding diagonal bars from each arm down to the stepper housing sides to create a fixed, triangular support which effectively links the turntable centre to the laser positions.  Like the idea of using turnbuckles for adjustment, maybe this could be extended to the camera as well?

Re: Atlas 3D kit enclosure mods

Hi navzptc
Need to replace my laser holders. The link to your braces file works fine but the link to the laser holders seems to be not correct. May I ask you to send me the laser holder file to my e-mail: [email protected]
Thank you so much. Kind regards Walter
