You could try stitching with meshlab.

Don't use the sprays for this scanner. It wil not work! The fuel scanner uses features from the object. If it cant find (and match) features, it is unable to make a 3D reconstruction. The fuel basicly combines two types of scanning; stereoscopic (eg; the same as what 123 catch does, it matches recognisable points and triangulates them) and photometric stereo (Light object from multiple angles, the way light changes tells you something about the orientation of the surface, but not about the depth). The innovation is in the combination of these two data sets; The stereoscopic method is rather error prone and very sparse and is unable to really find surface normals. The other is able to do that, but unable to find a depth. You can quite cleary see artifacts that are explained by this; The nose bridge is an area that is integrated based on normal field, using the depth image as a scaffold. The calibration of such devices is in principle a mathematical model that maps the camera focal length and their distance / rotation with respect to the other. If you change the focus / lens / orientation of the cameras, you need to calibrate again. They probably hardcoded the calibration, so you are screwed i guess. Calibrating the camera's yourself isn't that hard, provided you have acces to the software. It will probably help if you give the software a 'lot to work with' by scanning objects placed on a mat with recognisable points (QR/AR codes work quite well for this)

Some of them might have minor changes. I'm not into the hardware, so I can't help you with that.

Can you check how the model looks with the x-ray view? If there are red areas, it means the model is not watertight.

9:00 til 17:30 actually

Oh yeah, the springs pretty much look like that. The first prototypes even used clothespin ones (we had to bend them manually...).

The um2 can not be lasered. It can be milled with a CNC mill. If you want something that can be done with a laser cutter, use the UMO files. The UM2 blocks tend to break if you try to disassemble them.

I have no idea what happend, but it got fixed quite fast

The printer has no idea where the head is. Homing is simply moving the printer diagonally untill an end switch is hit. If the y switch is it, that point is now considered to be 0. Pronterface seems to assume that the direction is different or that the machine (as our older models do have it) have min x/y switches and max x/y switches. From your profile, I see its an um2. You can simply use the menu on the machine to home it.

1. I believe so. 2. Could be, but it's not officially supported.

I agree, but we're busy with all kinds of things right now, so I doubt if this is going to be implemented any time soon. Sorry :(

We already fixed this on the chat. It was sketchup that was up to it's old shenanigans again.

Because cura basicly does not know what type of fillament you are using. This is why for the um2, it's moved to the machine (and away from cura). This allows you to print the same file with different fillaments (Where before, you were forced to re-slice).

I'm not very good with electronics, but I believe that the switch has two states; pin 1 connects with 2 on state 1 and pin1 connects with 3 on state 3.

+1!

Once the new version is released you could write a plugin that changes this. I personally don't like encouraging people to use imperial units, because they are horrible (so I'd rather not invest development time in it ).

Yes, although it will take a bit more work to get the g-code in the right flavor. There are people who posted how to do this for other slicers.

Just because it's published somewhere does not mean it's accepted as prior art. Not everything on the internet is accepted as prior art; it needs to be distributed enough (in order to prevent modifiying the dates afterwards). I'm not sure if github is enough to be considered as prior art, so you would have to be carefull with that.

"Although some might seem cryptic at first, this is not intentionally so" <- Yes, yes they are. they are intentionally vague in order to 'catch' uses of the technology that the author did not think of originally. This is why, if you want a patent, hiring someone with experience is a good idea. This wil generally allow you to get away with patents that are just vague enough that you 'catch' more, without being to vauge so it could be invalidated by a judge. Also; A normal consumer is alway allowed to use the information in a patent, as long as you don't sell it. A patent gives the ability to prevent someone from selling your invention, not someone from making it (and a patent does not give you the right to be able to sell it either; which can cause problems in some cases). As a final note, always keep in mind that patents get public after 1,5 years in europe. This means that there are -tons- of patents that are basicly mines; You give an idea to the office, that date counts. Once you see that someone uses 'your' idea in that time, you pay the rest of the fees in order to sue. If noone uses it, simply don't pay and noone gets the patent. Patens are a horrible piece of law that forces everyone to use these kind of tactics.

Eh? I don't see how the surface quality would be better on the go. There are no fundamental changes to the technology in it. Its just a smaller (and more affordable) machine. I can imaginge that some people want it, but it's definately not a machine that i would buy (umo+ ftw )

With flat surfaces like that, the um2go might not be the best option, as it has significantly less building volume and no heated bed (which helps with preventing warping, especially on large flat surfaces)

Het aanpassen van spuitgiet matrijs was duurder dan de deeltjes er in laten zitten. Misschien dat het duidelijker in de handleiding moet dat die onderdelen voor umo+ niet nodig zijn.

A number of people from R&D will probably be there.

It looks like a bed adhesion problem, which can be caused by improper leveling. You can also improve it by using the glue stick.

Yay for subtitles, it kinda ensures that most Dutch people speak English
