Is there a way of telling if air bubbles are causing the issue I'm seeing?

a bubble would be a void if you only cure a single layer on all the bed

As I understand Michael, that is to ensure there is no air bubble on the bed.

An air bubble would be no adhesion at all

@Trish yes, of course.  I don't think air bubbles are a problem for me though?  Some bubbles bloop out the side when the plate comes down, rises a bit, then goes down again.  It's a [Creality Halot One](https://www.creality3dofficial.com/products/halot-one-cl-60-resin-3d-printer) if that helps.

**Update:**

The resin was still warm from last print, so I ran again (after removing the failed pancakes of course) and after a few hours I could see that nothing had printed this time either.

The whole reason to pre-coat the plate with **liquid** resin is to ensure, that no air bubbles are left under it and prevent contact of the plate to the resin.

A layer of cured resin throws off your 0.

According to Uncle Jessy ([see Youtube channel](https://www.youtube.com/watch?v=8SWGpY3LlX0)), you simply need to pour some liquid resin over the build plate and then leave it for a couple of minutes for the worst to drip off. No

He also recommends that the resin should be kept at a warm room temperature and that the bottle be thoroughly shaken before pouring it onto the build plate or into the resin vat.

He also recommends that resin should not be left to sit in the vat for more than a couple of days as it can settle and separate.
