Ender 5 Allen Key Bed Leveling Bracket

thingiverse

This is a simple yet effective auto leveling bracket for the stock Ender 5. It uses the supplied 2.5mm hex/allen key as the probe, and a microswitch I salvaged from an old computer mouse. The bracket is very compact and very light, designed to be printed without supports on the flat bottom side. If you have problems with adhesion, use a brim. Thanks to the original designer for the idea and the bracket for the Ender 3: https://www.thingiverse.com/thing:3903271 Installation # !! IMPORTANT !! AFTER UPLOADING THE FIRMWARE MAKE SURE TO TEST THE AUTO LEVELING WITHOUT THE ALLEN KEY! CHECK IF THE SWITCH WORKS BY MANUALLY TRIGGERING IT AND MAKE SURE THE OFFSETS ARE CORRECT AND YOUR ALLEN DOESN'T CRASH INTO ANYTHING! The microswitch I used is a HUANO microswitch with a 2mm holes, 6.5mm apart (center to center). If you're going to use a different sized switch and/or the hex key rotates when probing, make sure the hex key can fall into the slot, and make sure it takes *a tiny bit of force* to get it there to prevent the key from rotating out when the bed raises up. Alternatively, a limit switch or a flat ended allen key would solve this problem too. The switch is attached with 2 PLA pieces I've cut to length, heated the ends and pressed in, making a rivet. I then added some superglue to prevent it from wobbling. If you have bolts that'll fit, use them. I've attached the design files and dimensions if you need to make any changes :) Wiring For the wiring, solder 2 wires between the Normally Closed (NC) connections. (Common and NC) I recommend using a twisted pair for the wires to mitigate any electrical noise and make it look cleaner in terms of wire management. Then you can either attach it in series with the existing endstop or use a dedicated PROBE connection. configuration_adv.h // Will help you adjust the Z for the perfect first layer, then you can use that value as the Z probe offset :) #define BABYSTEPPING #define BABYSTEP_ZPROBE_OFFSET To make sure every print is using the leveling mesh generated, add this line to the start of the G-code in your slicer: M420 S1
