This is a simple grid print with 0.2mm (1 layer) in height to find bed adhesion issue ares. I was having an issue in the back right corner of my Elegoo Centauri Carbon and I wanted to confirm this. The grid shows the problem area

For me I was able to correct this with the bed leveling function. When the print is perfect it creates a nice square piece of netting that is surprisingly strong... or if you like popping bubbles in bubble wrap- some people find it satisfying to rip apart the grid into shreds.

These prints were will elegoo rapid pla.

Directions Drop STL onto bed ( designed for elegoo 256x256) Hit the auto arrange but to clear the warning for too close to edge. Slice and Print.
