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.

Use a spatula if needed to break off loose. 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. On the ender 3 you can remove the build plateand clean it. 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.

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. Clean off anything that is sticking to the surface. 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.

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 think most people have wires laying around or can get them fairly easy. Before starting to level the ender 3 s bed there are a few things you should do to get the machine ready. Make sure the build plate is clean.

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. Clean off anything that is sticking to the surface. On the ender 3 you can remove the build plate and clean it.

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. It will do this in 9 places around the bed. 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.

The whole idea is to spend as little and keep it as simple as possible. 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.
