First layer calibration.
Just thought I would share a test pattern I created to get my first layer sorted out.
Works well for me, it not only does start and stop, but lateral adhesion is easy to test with how easily the strips pull apart.
Also it's easy to see which part of the bed is out of kilter, as the eye can easily pick up deviations in parallel lines.
What I thought would be cool is a pattern you could print, then scan, then prusa software would read it (like a giant qr code essentially), then let you know what corrections were needed to be made. Or something 🙂
