    After the helmet, the next two projects will require detailed scans of complete motor/transmissions.... we do have various setups at work for rotary welding, none of them are heavy duty (capable of 50+ kg) so I've started designing up one that should be good enough to put 300+kg that I can scan these on. Scanning turntables cap out at 200kg and that one was $650 nzd lol out of my budget and it doesn't come with a earth clamp ability for welding 

    Not sure how useful a turntable would be for that, just hang it off a chain and move the scanner around?

    Now my question is would a radius'd mounting arm similar to a photogrammitry cammera setup be a worthwhile addition or am I over thinking this lol 

    I don't think that's necessary at all, it might help with photogrammetry but I don't think it'd do much for this type of scanner.

     

  2. That's not a bad idea. Would require me to get along with my 3D printer again though...
    Although so far I've preferred using a computer with the scanner. It's more powerful, you're swinging around less weight, and getting the scan off the phone to the computer is a bit of a pain.

    I think just using a bluetooth mouse app would probably work to press the button remotely. Or one of those bluetooth presenter remote thingies ziptied to the handle.

    One of the first things I want to scan is shiny(ish) white.... a mate who has died, his motorcycle helmet. I've been asked by his widow to make something special for his ashes, my plan was to scan it and print a smaller version I can use for approval and then as a buck to fit the sections of sheetmetal too.... it has a patina from all his trips and I don't want to clean any of this off by mistake when I clean off hairspray for example 

    Depending on the colour scheme, texture mode might work. Just pure white could be a challenge, and might require markers. A small turntable (maybe you have a welding positioner or something?) could also help for that.

    On another note, I forgot to add I experimented a bit with the included WiFi bridge as well. That seems to work fine, both with a phone and a computer. It seemed to have a little bit less bandwidth maybe than just straight USB-C, but not being tethered to the cable was nice.
    But what this thing really needs is a start/stop button on the handle, instead of having to reach over to the phone/computer.

    I've also noticed the phone app has an undo button while scanning, but the computer one doesn't for some reason. That's too bad.

    I think for now my biggest limitation is my Fusion360 skills :D Haven't had much more time this weekend to play around with the model. Last I tried was fitting some sheetmetal sketches to the mesh, which worked well, except that I defined my plane slightly wrong so it wasn't level. For some reason you can create a plane at an angle to a feature, but not another plane, which is weird...

    The top one is really good! The body detail is spot on, you could design to shape and style lines from that without issue. The bottom pic doesn't inspire too much confidence... are those lines on the chassis set by the software or did you add them? Looking at them vs the mesh there is almost 2mm of difference in places..... I'd be very cautous designing mountings to that 

    It actually doesn't show the whole picture - the mesh lines were from a few cm further back than the face shown. This sort of shows it better (not easy to capture in a screenshot):

    The idea is definitely to use it as a general reference, and build your own shapes from there, which is what I'm playing with now.

    These videos explain it quite well:

     

  5. Well, erm, wow. I did some reading of the manual (ludicrous, I know), and instead of doing the auto-processing, I set it to manual and set the resolution to max (same scan, just different processing).

    This is the result. So much more detail!

    It shows the thickness of the chassis here at 3.2mm, which is probably not far off.

    More later.

    I did wonder about the blue bits on the boat myself....convinced myself it could be seawater splashing up ....lol

    Regards Stephen

    Oh, it definitely could be :D Just nitpicking really. Not sure how terrible it would look to have those few spots shiny instead of blue though, might be ok without having to start all over?

    But as you say, the guy you're making it for is the important opinion to get :)

    As ever - MS can't solve mechanical issues, and always go back to the basics rather than deeper down the rabbit hole! Glad you're up and running.

    Yeah, but having a new engine build combined with MS makes it difficult to tell where the problem actually is. Ideally you'd do one change at a time, but that wasn't really an option in this case, sadly.

    The results look pretty good - the real test for me would be to compare a few measurements from the software on the real car to see if you're getting accurate results, not just pictures that look like the thing you scanned?

    Not doubting it - just want to know how it comes out because the obvious use-case is scanning things so you can make other things fit them, so if the dims are wonky it's a non-starter.

    That's my next step, yes. Making for Motorsport did a test with a 1-2-3 block and came in at <0.5mm error IIRC.

    Might be worth trying the matte spray that folks like retropower use. Can you use the stick on reference dots too with your software?

    Yeah, I bought some of the spray, but haven't used it yet. Would probably help, didn't have much time to screw around with it yesterday.
    It can work with the dots, but that seems to be a different scan mode. Haven't tried that yet.

    Did I slip into a non-Land Rover forum by accident?

    What, too modern? :SVAgoaway:

  11. Tried it out on a car yesterday (using @Escape's P38 as a model because it doesn't have a rear bumper on it yet), this thing is brilliant. Now to learn how to work with the software... especially that GOM Inspect stuff that Making for Motorsport uses, appears to no longer be simple to download.

    Again, not perfect, but a hell of a lot better than what I could manage with a tape measure.

    Tracking went fairly well, it mainly got confused at large flat surfaces (side body panel), and the towbar mount tube/bracket also confused it a bit, but I think that's mainly due to light.

    I also took a quick scan of the other side, and that didn't go quite as well, but still not bad! Again, I think light was important here, as this side was less well lit.

    Maybe a ring light like this mounted behind the scanner would work. But just pointing a few portable lights on the underside already helped a lot.

    Now to learn how to use MeshMixer and such...

    That video can't be right, where's the loud clicking noises that you can't track down? 😡 

    There are some very nice clicking noises, and we're fairly sure they're just from the special lifters :P

  13. Well, it arrive yesterday. Just tried my first scan, to keep with the Land Rover theme, I scanned my Lego Defender.

    Used it connected via USB-C to my Surface Pro 8 for now, will try later with the WiFi bridge, as the cable did get in the way a bit.

    No special prep was done, just turned on the light above the dining room table.

    I'd say that's pretty good for a first attempt!

    In just this bike I have 4 days of measuring and modeling and I'm only 2/3rds done.... unfortunatly alot of what I do is road going stuff and to get pre-build approval from the authorities you need drawings.... so I'm spending alot of time on each project just modeling components etc.... my justification was if I worked the 4 days its paid for lol 

    Yeah, precisely this is why I ordered a scanner. It should be delivered today, might get to try it out on the car soon.
