3d Printer Bed Leveling Jig

This is a simple bed leveling jig using simple and cheap parts.

All we need are a tiny magnet, a T-slot nut and a metal ruler.

Metal Ruler https://www.harborfreight.com/hand-tools/measurin...

Use the allen wrench included with the printer to loosen the screws holding the tensioning bearing in place and insert the T-nut.

Use the magnet (or use a piece of a magnet) to hold the ruler onto the T-nut.

Now just move the ruler to each corner and adjust it until all 4 corners the same height on the ruler and check your progress on the Bed Visualizer in Octoprint. It's usually good if you have it within a millimeter. Now just put it back together and get printing!

Tip: use a hefty enough ruler that it moves with the bed, if its too light it will be a pain.
