Diy Auto Bed Leveling Ender 3

For any 3d printer that doesn t have auto bed leveling such as ender 3 cr 10 cr 10s anet a8 precise bed leveling is something that every successful print needs to nail in order to get it right.

Diy auto bed leveling ender 3.

I think most people have wires laying around or can get them fairly easy. Make sure the build plate is clean. Auto bed leveling probe since the ender 3 uses the same x carriage design as the cr 10 there are already dozens of printable brackets to choose from. Before starting to level the ender 3 s bed there are a few things you should do to get the machine ready.

By setting the custom startup g code to create a bed leveling mesh before each print the printer will deploy the end of the bltouch and then lower the print head until it touches the bed. I build this z probe for auto bed leveling with existing parts in my bin i don t have a bltouch but it works great and cost almost nothing to. It will do this in 9 places around the bed. Clean off anything that is sticking to the surface.

Make sure the build plate is clean. The two items above are the only purchases i had to make to install auto bed leveling on my ender 3. Downloading the most up to date firmware directly from the marlin website configuring the firmware for the ender 3 and for auto bed leveling compiling the firmware using the arduino ide and resolving conflicts uploading the firmware to the ender 3. Use a spatula if needed to break off loose.

Before starting to level the ender 3 s bed there are a few things you should do to get the machine ready. Bed leveling is literally the foundation or making sure that the foundation is set up correctly at least of a good print. The box style sn04 sensor is cheap compact and looks like it would mount on the carriage without additional hardware but it sits just a bit too far from the build plate to get triggered. Use a spatula if needed to break off loose.

In any case the main steps include the following. I created my own diy abl auto bed leveling sensor and pcb for the creality ender 3. The bltouch replaces the ender 3 s z endstop switch. I also used some 14ga silicone wire to supply power to the sensor male jumper cables cut in half and soldered to two 22ga silicone wires for the z endstop wires.

The whole idea is to spend as little and keep it as simple as possible. Clean off anything that is sticking to the surface.
