Crash leveler for Dual Z-screw 3D Printers (Ender 3, Mega Zero etc)

UPDATE: I've added the "Compact Crash Leveler" remix by @foureight84

This is designed to fit all 3D Printers with Dual Z-screws that use 40x20mm Extruded frames. eg Anycubic Mega Zero, Creality Ender 3 etc

This will allow you to level your printer using the same method as Prusa printers, just drive the X gantry up to the top of the frame, and gently "crash" into the levelers to level your X gantry.

It's designed to be installed using 2x M4 Cap-head bolts and 2x M4 T-nuts per side.

I recommend printing these with 6 layer top / bottom and walls with 25% Cubic infill for maximum strength.

I've written a simple Gcode script to level your X-gantry on anAnycubic Mega Zero v1.0 - due to having a heated bed, I hit the crash revelers at ~215 mm Z height so have set my leveling command to 220mm max Z height. You might need a taller Z height depending on your printer config.

To use it, just put it on your SD card and "print it" - it'll tell you what it's doing on the screen via M117 commands.

This script assumes you have ABL, if you don't then this script could make a real mess so please be careful.

You shouldn't need to run this very often, eg once a week tops, or before big long prints to make sure everything is spot on.
