I am considering getting one of the Creality 3D scanners. Has anyone here
used one and imported the resulting STLs into OpenSCAD? Are they usable in
OpenSCAD?
I build electronics projects and typically hand-build 3D models of the
PCBs, displays, etc., to help design the cases. I would truly love to be
able to merely scan them and import them into the case design.
Thanks! Len

Not here. We have such a scanner for linuxcnc, but I haven't messed with
it, written in the original python decades ago, supposedly handles
.png's and .jpg's for input but when fed to linuxcnc does not fare well
at all. I wrote, just to see if I could using an optical height probe,
found a 2x4" rifle magazine floor plate at 50 thou resolution was both
a several day project for my cnc'd g0704 and the backtrace was not
easily recognizable. So I hadn't developed any more interest, if I need
that, I just get out the calipers, measure the board and make it in
OpenSCAD with a cube statement.
Did you just elect yourself as guinea pig? :o)> Somebody should.
But anything Creality makes needs copied in quality parts. Creality
doesn't. And if something breaks, you can't get the parts to fix it.
I probably have $2,800+ in an old Ender 5 Plus, a big printer that OOTB
would layer shift Y at only 20 mmps, now runs at 100+ mmps with 10x the
accuracy. But I've also been 3 years getting it there. It also prints at
that speed in PC, something no other sub $1K printer from anyone can do.
Biggest change was to switch XY motors to stepper/servo's running on 72
volts. And subbing a 20mm sq cf tube for the X transport bar with an
mgn9 rail top and bottom. That's a weight reduction of around 50%, an
improvement in accuracy and speed. And it has none of the gcode
modifying speedup tricks called /input shaping/ the $900 printers use to
get the speeds they advertise but cannot actually do on an everyday basis.
I also have a tronxy-400 thats about half done with a similar rebuild,
but I am now 90 yo and diabetic, slowing me down.

Take care of #1, Len., better than I have. OTOH I've had one hell of a
ride. And I wouldn't want to miss too much of it other than the 3 wives
and and 5 children I have outlived.

I bought the ferret pro, about a year ago. I have not had time to
practice very much in using it. The stls are full of holes. For pcbs,
when I was into that. I'd use an ordinary document flat bed scanner. It
gets the outline pretty exact, and it is easy enough to get the height
of individual components.
I'm not sure if much improvement has been made in the past year or so,
with the creality stuff, but it was a very much a case of practice in
using it, and the software had plenty of room for improvement. If I get
time, I'll find a pcb, and spend a few minutes scanning it, and show you
the results.

I model all the PCBs I use in OpenSCAD. I don't always do all the
components but I do the ones that affect the enclosure. If the PCB is open
source in a Kicad compatible format I can get the component positions from
that, otherwise I measure it with calipers.

Yeah, that's what I was afraid of.
Gene: I started out with an Ender 3. A great machine to learn on and to
modify, but don't expect much help from Creality.
Raymond: Yes, the ferret is what I am/was looking at. I look forward to
seeing something that you've scanned.
nop: Your library is awesome, and I intend on using it for modeling some of
the wiring. But, there are still parts/assemblies that aren't there and,
even though I thoroughly enjoy modelling these in OpenSCAD, I was trying to
save some time.
For my own boards, I can export a 3D model of the board from EasyEDA and
then quickly run that through Prusaslicer to repair. The resulting model
is not good enough to F6, but it >IS< good enough to preview and that's
generally what I need for case design.
With all of the current AI craze, I wish I knew how to train an AI to
quickly, reliably repair OBJ and STl 3D models so that they were viable for
OpenSCAD.
Thanks, everyone!

It might be possible to convert the point cloud into voxels, convert the
voxel into a mesh, and do some post-processing on the mesh. If the
target features are cube like (flat surfaces, right angles, etc.), this
may work well.

I have had a variety of Creality and RevoPoint 3D scanners, mostly as a
result of KickStarter campaigns, where I got "deals". None of them were
satisfactory for my purposes. They require that you keep the scanner at
a somewhat fixed distance from the object being scanned, and they show
this with a display on your computer, to which you attach the scanner.
You can either look at the scanner and object, or the screen, but not
both, and that is very frustrating. I even asked a friend to monitor
the screen while I tried to scan (shouting out "closer!" "back!") and
that was too frustrating for both of us. I tried using a tripod and
rotating the objects with a black back drop. I tried adding colored
dots. I tried Photogrammetry. None of it would work reliably.
I bought the RevoPoint Miraco, and then I sold all of my other
scanners. It is expensive, but it is all-in-one: scanner, display,
processor. It uses structured light, so there is no need for dots
(although I spray shiny objects with foot powder). You can see the
closeness display while you are scanning, so it is easy to keep the
scanner at the right distance. I use single shot mode, where each press
of the button takes a picture, rather than video mode. It is much
easier to discard a single scan if the scanner gets confused about sync
with the object. And you can import the point clouds to your computer
(via WiFi) and then use other tools to finish the processing, including
RevoPoint's Revo Scan software. I have scanned two sides of an object
and then merged the point clouds using CloudCompare. All of this under
Windows.
Highly recommended, if you can afford it.

(via WiFi) and then use other tools to finish the processing, including
RevoPoint's Revo Scan software. I have scanned two sides of an object
and then merged the point clouds using CloudCompare. All of this under
Windows.
Highly recommended, if you can afford it.

For my own boards, I can export a 3D model of the board from EasyEDA and
then quickly run that through Prusaslicer to repair. The resulting
model is not good enough to F6, but it >IS< good enough to preview and
that's generally what I need for case design.
With all of the current AI craze, I wish I knew how to train an AI to
quickly, reliably repair OBJ and STl 3D models so that they were viable
for OpenSCAD.
Thanks, everyone!

For pcbs, when I was into that. I'd use an ordinary document

easy enough to get the height of individual components.
I'm not sure if much improvement has been made in the past year
or so, with the creality stuff, but it was a very much a case of
practice in using it, and the software had plenty of room for
improvement. If I get time, I'll find a pcb, and spend a few
minutes scanning it, and show you the results.

this with a display on your computer, to which you attach the scanner.
You can either look at the scanner and object, or the screen, but not
both, and that is very frustrating. I even asked a friend to monitor
the screen while I tried to scan (shouting out "closer!" "back!") and
that was too frustrating for both of us. I tried using a tripod and
rotating the objects with a black back drop. I tried adding colored
dots. I tried Photogrammetry. None of it would work reliably.
I bought the RevoPoint Miraco, and then I sold all of my other
scanners. It is expensive, but it is all-in-one: scanner, display,
processor. It uses structured light, so there is no need for dots
(although I spray shiny objects with foot powder). You can see the
closeness display while you are scanning, so it is easy to keep the
scanner at the right distance. I use single shot mode, where each press
of the button takes a picture, rather than video mode. It is much
easier to discard a single scan if the scanner gets confused about sync
with the object. And you can import the point clouds to your computer

But you didn't mention a ball park price. That would have been helpful.

The Miraco was $1,300, but they reduced it to $1,000 when they announced
the Miraco Pro (which does not appear to add much, to my eyes).
