Ender 3 V3 SE Bed Leveling

Hi All,

In this instructable, I will be talking about the auto bed leveling issues with Ender3 v3 SE and my attempt to fix it.

There are no tutorials online to help fix it.

1. Glass bed
2. Spring and bolts that are Ender 3 compatible
3. Spirit level

I bought an Ender 3 V3 SE, 2 months back, at first I found it an amazing 3D printer for beginners.

It started with an adhesion issue. I would typically clean the bed with alcohol, and adjust Z offset.

It worked, Then as part of troubleshooting. I adjusted the X-axis gantry and made sure everything was tight

But as I printed more, I noticed that the auto bed leveling was not working

Based on a series of experiments, I came to the following issues

• The Printer does not consider leveling mesh data
• Gcode pre-scripts also do not use mesh data
• Adhesion to bed is not good
• Firmware 1.06 promises to fix this. but I am unable to update the same (Many others have reported to Creality)

Conclusion: I must fix this myself

• I got a tinted glass(4mm thick) cut from a local glass store (235x235 mm)
• Yes, it works, you do not have to buy expensive branded glass beds
• I removed the build plate and 2 screws as shown
• I did not remove the magnetic bed, just placed the glass bed on it
• Secure it with some paper tape
• Clean with alcohol
• Auto level and test print, If the first layer test fails like mine. go to the next step
• As a reference, the first pic is data for the original bed and the last one is for the glass bed

• I bought a manual bed leveling kit that was compatible with any Ender 3
• We need to replace the existing screws and spacers with the longer m4 screws and springs
• Spacers on the left side of the bed were smaller (2mm or so)
• From the pic, you can see, that the bed level was bad, I thought I made a mistake
• Initially, I used a spirit level, tighten the screws that were +ve and loosen where -ve
• Post that I used the mesh data to adjust. and then running auto-leveling
• With at least 6 iterations, I got it to a good number (variation 0.1 mm)

• I managed to get the bed manually leveled
• Now able to print with a little adjustment of z-offset
• I will also wait for better firmware that can handle mesh data properly

Please feel free to share your suggestions or if have another method to get better results

1. We can use Silicone spacers instead on the spring and use the original screws
2. Also we can adjust the screws to get best leveling
