Linear rail guide for horizontal movements

Showcases
1

I have always struggled to get really good scans of very oblong items like slot cars with my Mini.

To try something new, I purchased a linear rail guide (like those used for 3d printers). The item arrived last Friday, so I quickly designed an adapter for a camera thread and start testing (the feet are provisional, btw)

What you see is the very first attempt I did. I am really pleased of how well it went :slight_smile: I used continous scanning + single mode to fill some gaps.

The second test was a bit more extreme. I tried to scan an old vacuform kit.

This time I only used single mode, and the result is -in my eyes- spectacular. All the details of the kit are visible on the scan (the panel lines, the doors…)

So, I strongly recommend to every Mini user to get something like this. It is cheap, easy to build and the results are fantastic!

Hi Cath!
Another great idea! So you use it to keep the same distance from the object and I guess for stationary/single shot mode only?

Which Mic stand brand/model do you use, as depending on where the scanner is mounted especially with Miraco there is quite some load it has to be able to hold securely.

I surely wouldn’t mind a photo of
using such a mic stand with Miraco at some time😆

cheers

Yes, the key here is that you guarantee that the distance to the object to be scanned remains constant whilst allowing free movement. If you have a setup with a telescopic arm (the one that comes with Mini 1 tripod is very handy) you can have the same distance in the whole XY plane.

It is a bit like a Lazy Susan, but for linear instead of circular movements.

I also like your object holding rig. :laughing:
I like developing scanning strategies. Thanks for sharing yours!

Can you give some recommendations regarding that linear rail? which one do you use? would you choose another one if you would build that jig again?

I got a pretty standard one, no special requirements:

It works just fine
