Question about IR Sensor and Buildtak
-
Regarding the IR sensor, it works better with opaque surfaces than with transparent ones. White opaque should be good.
-
The origional Fleks3d plate was clear PC with what looks like a sand blasted surface which made it a glowing white. The IR sensor did not work with it at all (head would crash). You might have good results with your sensor and a sanded surface or you might not. Try it and let us know

I will try to go today to the hardware store to see what they have.
I think last time I went there they had the transparent I got, and one that is like your's, but white (glossy maybe? not sure about the adjective). I think I still have enough transparent at home to try it as well.
Once sanded, both should be matte, the transparent will be kind of grey, and the white, a non-shiny white… will need to try both. Regarding the sanding, I will get several gr sand paper... regarding how it should look like, how much should I apply the sanding, @whitewolf? What worries me about the sanding is that, as it's a manual process, the surface won't be equal... any advice?
Regards

white will probably work…

I just used 60 grit with water until the surface looked completely sanded with no sheen left over. then washed with water and dried the black dried to a whitish greyish on the whiter side. Obviously that effect on clear would be more like a cloudy stained window and white just a dull surface
-
i did start with 120 grit but was not happy with the results compared to the original flesk3d plate
-
I just came from the hardware store, what they have is no PC but polystyrene, so I didn't buy it… and checking what I have at home, is the same.
I'm now looking for professional builders shops here, to see if they have some rests of the appropriate size to kindly ask for...
I will keep you updated.

Where are you in the world also look for Plastic's suppliers rather than Builder type places

I'm in Spain.
I've found today a place where creates and install street adverts and plastic roofs, and they sold me 2 pieces (1 white, 1 transparent), I will pick it up tomorrow, as I've asked them to cut it to the size I need.
I won't be able to sand it until monday… I will keep you updated.
Cheers

If you do a light sanding just to take the gloss off, you shouldn't have to worry about an uneven surface.
If you are, use a sanding block to help maintain even pressure.

PC is pretty tough stuff, you really are not removing any material like you would from softer stuff (just a fine dust). its really about getting an even roughness. If you take a look at the Flesk3D plates which is the commercial equivalent of this. The surface appears to be sand blasted for an even etched glass look and feel.
The closest I could come to the original look and feel is 60 grit wet sanded with a vibrating sander, but a lot of time with a sanding block could accomplish the same thing.

@okercho: Any updates on your test with clear sanded & white sanded PC?
As within spain it is also quite hard (impossible) to find an supplier for black PC here in Austria/Germany.
It would be possible to paint the underside of the pc like DC did it with PEI, but as sanding is needed i think it the probe wouldn't benefit from the painting. -
Has anyone experience with the IR sensor and black color PEI sheet?
