@Kevin_Grisko see the end of the you-tube video in post 24 above - a spot test on it’s own doesn’t show you the contrast, and I have another test print running at the moment.
@ChristopherBarr you should read some of the background - when I said a simple aperture external to the laser has been much discussed already, I meant that it has been mostly discounted - mainly because of this Form1+ laser flare issues illustrated - pics and video and this Form1+ laser flare issues illustrated - pics and video
I say mostly - because of course @JoshK had his success - but then sold his printer, so there was no follow-up and I really don’t think it’s a practical approach because of the reasons listed above.
