Calibration plate preview wrong?

I've used the following settings for the calibration plate:

But the layer preview shows this sort of thing:

I'd kind of expected to see little dots like in the changelog - any ideas what am I doing wrong?  Am I doing anything wrong?

My projector settings are:

I am running build 1447.

Thanks in advance.

It is correct view based on your settings

Hi Shahin, thanks for the speedy reply.

Do my settings look reasonable?

Just seems odd that there are only 12 layers in the calibration plate and the last 6 are completely black.  Or is the preview not showing me the whole layer?

It is normal, nanodlp jumps backward and forward among these layers.

I had a similar issue, it turned out that the calibration cubes I was printing were too large and too many to fit on my build plate. So I had to change the pillar width and sheer. Hope this helps!

Ah, right, makes more sense now thanks!  It seems the blank layers in the plate mentioned above were caused by the pillars being outside of the printable area - clearly my settings were wrong.

I've tweaked the pillar width & sheer values and now the plate looks like it might actually print something useful:

In case anyone else has a similar problem in the future, these are the settings that produced the above plate:

Re: Calibration plate preview wrong?

Could anyone let me know what the different parameters are used for? I'm using the @achingbrain parameters and the preview layers are completely empty.. nothing shown.

Plate depth?
Pilar width?
pilar shear?
Extend pilars' base layers?
Rectangle for resolution measurement width and height?

Thanks!
