Geeetech i3 Pro B X axis level tool

thingiverse

I'm sure many people will struggle with setting the X axis level by turning the Z screws while measuring against one reference or another. However, there's only one reference that truly matters: the Y axis smooth rods, as they're what the bed travels along on. I've used devices created by others that heavily rely on proper alignment if accuracy is to be achieved, and it's surprisingly easy to get a little off. This design clips onto the X axis rods above the Y axis, and you lower the X axis either manually or through PC increments until you feel a bit of drag using our standard paper test, which we also use for nozzle testing. Then, unclip the gauge to the other side above the Y rod and repeat the test until you're confident it's correct. The gauge is intentionally designed to be easy to knock off the rods in case it's left on by mistake or bumped. If you find it won't stay on the rods by itself, refer to the image where I used a length of 8mm rod to smooth out printing bumps and it should stay on its own. Print it on its side with supports. I use a few Gcode commands to put my printer in a suitable position for testing. My i3Pro b should be roughly similar in dimensions, but factors like hot end length and compression on the hot bed springs will change the actual distance between the axis rods.
