About this 3D model
I mucked about with this for far too long when starting resin printing. The order of which Elegoo set their calibration to is... unintuitive. This template shows where on the buildplate the different exposure zones will be located, and which number is assigned to which segment. Place this on the buildplate, add your calibration models and then delete this. Shoutout to LSTAR for his grid divider. https://cults3d.com/en/3d-model/gadget/saturn-4-ultra-resin-calibration-tool-gridlines
