Everts NuVat

[TAJS]

I just received a NuVat and am excited to use it, however, when trying to calibrate the build table, the build table will not go down far enough to touch the surface. Apparently the the nuvat surface is not as thick as the pdms.....is there a way to manually lower the build table to where it touched the surface? Any suggestions?

worked fine on my V1.1 ! Worked great i will post some pics tomorrow

I changed the z value from 10400 to 10800 and was able to calibrate.....and the printer is printing :)

TAJS,
Perhaps, as a temp solution you could add a number of washers on the 1/4" screw that connects the black platform to the gold arm.
If you go too low you will loose alignment to the arm, and could bump on the sweeper will building.

A better way would be to tweak the home offset value in settings, but I don't know if then you bump to the VAT.
I don't know what value you should input, but I m interested to the solution for my mod as well.
Please keep us posted.

[Yianni-VJ]

You are too fast TAJS :)
I took longer to write it, than you to fix it !

[Yianni-VJ]

so the value reflects mm, inches or steps?

[TAJS]

Thanks Yianni! I think 1mm is 200 steps...... here is where I found the info.....

Could someone please share Evert's contact information so I can order a few of them?

Has it been established this works for Jewelry without any problems (such as leaking resin into the projector?)

Or are people still in that bold testing phase.

You could also expand the 4 screw holes in the red platform into a long rectangular-oval by milling or by using jewelry tools. Now the Platform will touch the table and you can leave everything else alone. this will allow you to run both type of trays , with Pdms or Evert glass and be able to calibrate them easily. The platform screw area should slide up and down smoothly without much pressure when the screws are loose.

I am running an evert glass on one of my aluminum trays and I also put the glass on my Acrylic tray as a test. Seems to be working fine.
Will know tomorrow as These are 6 hour grows overnight.

We are doing test on the NuVat. After all info is in MIke should post user info. I think Evert will start selling then. This is my understanding as of now.

Robert

[Robert Howle]

He is correct. It is steps (200 steps = 1mm).

I have run my Evert glass on my 1.1 version of B9 since August.
I have not had a problem with the table setting down on the glass.
I don't know about the 1.2HD ver.
I do know that some of the tables needed to have the long holes where the screws go in ground out further on some of them as they were not dropping down far enough on some of the earlier 1.1 models to touch the PDMS. but that was only a few I heard of here.
yours might be one of them. you can use a setting bur to grind the lower or upper part out further to allow it to drop down but that sure seems strange considering mine uses almost all of the depth so it is possible to need it to grind it out.

[Robert Howle]

Here is where u change the distance (number of steps) to allow the arm to move further down the z slide. On the one machine (1.2) that had the holes drilled just a little to high (for the Z slide install) had to add about 2.5mm (600 steps) to get the table to contact for good calibration.

It is the "z home Offset (steps)"

This is for the 1.2 version. Don't forget to "save values" .

Hi TAJS .. Can we see some photos . Of the vat?

[noahbern]

Ok so here are my results!

I think it worked GREAT besides the first 2 base layers being hard to release!

These are my times.......

I just was hoping people could help me with the 1 issue i had which is the top of the ring
the detail isn't there. I was having a hard time making that work with the pdms. What could
this be from and how can i fix it? Please help.

[Robert Howle]

Is this 1:1 mix. Are they cleaned up and dry when u took pictures. Notice in your print data that the over on layers is 0 sec. You are getting no perimeter pixel extra time. Why is this?. Is this with Mike's settings for materials catalogue?

Robert

[Robert Howle]

@Mazen The vat looks just like your vat before u put in the PDMS. The glass is just coated (very thin like maybe a very thin layer of clear fingernail polish) too thin to measure by ordinary means. There is really nothing to see, except maybe the silicone around the edge of the new piece of glass.

Robert

[noahbern]

Yes the 1:1 but mine doesn't have the glass filter. and my msm is .2
Because of that I had to find my own times which I am glad to share...
They took awhile for me to get even close..
