Re: SLS on a budget - camera and lens choice

Alright... I made myself some panels using din A4 cardboard with printed markers and some wooden panels. Calibration worked right away. Then i went on to make a first testscan... I sacrificed my trusty rubberduck for the cause and this is the result. 30 Scans (360° loop) were made on a single heigh...

Re: Some of my scans

Unfortunately, I do not have practical experience in using cameras with a global shutter ... More precisely, I have one camera with a global shutter 0.9MP 120fps USB2.0 - and it turned out to be completely unsuitable for scanning - because for the strongest compression of MJPG and USB2.0 interface....

Re: SLS on a budget - camera and lens choice

I thought i'd keep you guys updated... My parts from china finally arrived. I went with OBNRacers recommendation and bought the 12mm ZLKC lens which fits nicely with the YW500U3 camera. The FOV is also perfect. The setup works so far, but i now need calibration plates. I printed them on cardboard a...

Re: New DIY turntable

I made the openscan turntable earlier in this year. Fun to build but not much use for me.... What I have missed for a long time is a slightly larger turntable that can handle a lite more weight. I looked in the garage what I had and designed with the parts I found. Cost was close to zero. Some 3D-p...

Re: Some of my scans

Here the other day I scanned a D4.5mm drill (dual camera "composite" (not advanced) mode) .: drill_D4.5.jpg No additional frosting. The drill was almost new, oiled; after drilling, sticky pieces of chips remained. Here you can download the resulting STL model. A 50mm calibration chart was also used...

Re: Some of my scans

The first "full" scan made using two MindVision SUA630M-T cameras. Scanning, to increase accuracy, was carried out in composite (not advanced) mode, because with full resolution of the cameras, the RMS on my tables reaches 1.05! However, this did not prevent the scans from forming into a single uni...

Re: MindVision SUA630M (USB3.0 IMX178)

In EU rangevision is not selling the software. At least it's what they told me. We are waiting for your updates! Yes, the program is available only to a limited number of Russian fans who have created their 3D scanners and are actively involved in the development of the community. At the moment, ow...

Re: 360° alignment issue and calibration settings questions

Thanks Micro0 for the information. How did you mill the bigger circles with white dot in the middle? Based on the official HP printouts the black dot is /30 from the scale. Is the size of the point important or just only the position? AFAIK Just the position. That is the toroid I milled with the sm...

Re: 360° alignment issue and calibration settings questions

I also did a set of glass panels that I put 3 layers of sign vinyl on. The bottom 2 layers were black and the top white. I then plunged the 1/4" endmill just through the white (.003" exposing the black. Getting the vinyl completely smooth was a pain though. My VMC can repeat .0002" accuracy fairly c...

Re: 360° alignment issue and calibration settings questions

@ Micro0: One more question. You wrote "It wasn't till I made a Hyper accurate set on my VMC that I realized just how important the positional accuracy of the dots was." Can you tell me how you machined the panel using a VMC/CNC? I have also a CNC machine but i have no good idea how to get the blac...
