Re: SubG+ Mixtures

Yep. Usually it will not matter, but I found that yellow and red work a little bit better.
Also you can mix colors :) So basically the most important is to find appropriate concentration. This can be made with a series of tests.

Ahahhah) Googled it... That's me! For sure! :D

Take it to the outside... That's brilliant! I expect it to boost both v1.1 (without UV filter already) and v1.2 anywhere 2x to 4x times.

Re: Everts NuVat

Hi Robert, so have you dropped using PDMS altogether now? Are you rings still coming out as good as they did with the PDMS? Anyone out there have any accidents with glass coming off since what happened with Mike? Thanks! Luckily so far - nope. But I'm printing so far with NuVAT ONLY in smallest set...

Re: strange print glitch

Yep, looking at that again, it looks like something very strange happened during the slicing. Would help if we had the original stl and layout files. In my cases when I got such a glitch I just re sliced all the same layout with the same files and glitch was gone. Maybe it's something with memory-C...

Re: strange print glitch

I'd not be so sure. As I said somewhere earlier I saw few (one or two in fact) times when after slicing there was some weird glitches of model "half-doubling" or once it was "flipped piece". But it really happened very rarely - like once or twice in my almost 2 year practice. Als...

Re: Projector woes and replacement options

Not really. Mike offered a one time upgrade option for all who have 1.0 - 1.1 machines. Basically it's a discount for a new 1.2.
Or of course you can try to step into mess of making your own projector mount, which also will force you to upgrade frame and so on. :)

And don't forget rubber (silicone) dust gasket as in v1.1. I believe when one will extend lenses there will be gap as in v1.0. And that should be closed in similar fashion to v1.0-v1.1 with rubber gasket to prevent dust make it's way inside.

Re: Curing in the microwave

Looks like controlling the temperature is critical here. How this can be achieved? Maybe just trial and error. If you got cracks then you should use 2-10 time setting instead of 3-10. If cracks will appear again then try to lower the power of microwave. So can anybody explain to me what do you mean ...

Hello guys newbie to the forum here. I believe most oleophobic coatings might work as a good alternative for sylgard 184, qsil 216 and others. Most high quality screen protectors for smartphones use these coatings and are easy to apply. One having a spare screen protector could easily try this in b...

Hey guys, how are you gluing NuVat glass in there? I tried ordinary sanitary/aquarium silicone but it won't stick to acrylic firmly. Also tried a bunch of building glue like polymer, polyurethane and Liquid Nails Heavy Duty (biege). Only biege is working good. All others do somehow dissolve in resin...

Re: FunToDo resins

IMHO that cracks are "leftovers" from low shrink. When it cure it tries to shrink, but it's hardness will not allow it to, and that will allow it to retain some structural stress.
That's my IMHO.
Yes, I also mentioned very small "sweet spot".

Don't froget about calibration. If you do print some boxes on one calibration, then adjust, wait some time, calibrate projector again... you will have different accuracy :)
