Re: Nylon

If it says minimum is 40 then it means the settings (exposures, etc.) are not in the machine.

Believe me, if the nylon, with it's specific properties, would do the things it's designed for at 30, then Mike would have put those settings in the machine.

Re: Laptop not finding IP of printer

Oops, late night brain dead. Sorry. Yes must be core.

I was having problems with my connecting to the printer via wifi and realized my router was over 10 yrs. old. Bought a new one with 4 ant
and connection is almost instantaneous.

Re: V1.2 for sale

Reminder, this is not a B9C or Core machine. It has to be a 1.2 with the HD projector.

Go in and edit your post to call the machine what it is, B9 version 1.2

Re: checking models

U can set the export dialogue boxes so that it won't allow the export of non manifold objects.

I use the Object checker in Matrix.

Re: Need help with a larger print

You can't print in two pieces and then join with wax or resin after curing? Done it many times myself and for others on my 530.

Re: Surface Roughness

I have stated in the past that I use the Zeiss lens spray on all the surfaces that light must pass through. I also stated that it is not recommended by the staff at B9. This being said, I have seen no ill effects on the printing surface. I am approaching nearly 800 hrs of print time on a single vat....

There is a spacer ring in the projector mod. I would think u could just remove the spacer and dust ring.

Check the surface of the glass bottom of the vat. any smudges or finger prints on the glass bottom or glass inside the machine will cause that. I use Zeiss lens cleaner and a microfiber cloth. Also check to make sure u don't have a "shadow" image on the print surface of the vat. Cleans wit...
