"Do not look directly into laser with remaining eye..." Yeah, I did laser light shows 40 years ago for the larger planetariums, a 5W laser is a very dangerous instrument.

Lol, you're certainly right. I've already gone through a hobby phase with 445nm diodes back when 1w was about the max you could (somewhat) readily find. Geez now it looks like those are easy to buy in a fully built pointer. Anyways that makes me an expert in no way but at least I'm familiar with all the lectures and scary stories.
5w is probably the max power that will fit on the gantry from a practical form factor perspective. I guess I'll continue to browse around the web and see what's out there.
Well, to be perfectly honest, it looks like I can more easily and probably more cheaply purchase a 3 axis cnc kit from china before I retrofit a half decent laser toolhead into the QIDI. Realistically the CNC would only work on wood/plastic/pcb, which still probably outperforms let's say a 5W laser diode for my needs not to mention the extra axis.

240 x 180 x 45 mm working area, and just a smidgen more real estate on my workbench.
That's probably far enough off topic for today.

UPDATE: I am printing this again and only one this time and the "shadow" depression is still there from the first layer. I measured and it is the exact dimension of the hole in the middle. See the image and how it lines up. I have no idea why unless the mesh has become corrupted.

Some video of it printing that area might help too. Is the second nozzle heated?
Is the other nozzle heated even though it isn't extruding?
