When and Why to Print without Crumb Tray

This post (and the file attached) are handy:

No-Math Focus Ruler

Leveraging the recently-released Set Focus tool, I’ve designed a tool to help place materials when the crumb tray has been removed, no maths required. If your material is between the lines while resting on the bottom of your GF – not the crumb tray, you should be able to use Set Focus in the UI. If the top of your material is below the bottom line, use your favorite method (sheets of PG, tiles, 3-D printed stands, matching sets of trained hedgies, etc.) to elevate it and recheck. Repeat until …

Cut the ruler (best from clear acrylic, so you can peer right through it) - it’ll show you the zones where you can and can’t work without the tray. Get the top surface of your material in the “OK” zone and use the “Set Focus” tool in the GF interface and you should be golden.
