Looking at how to level your Ender 3 (Pro Included) print bed? Then you are in the right spot. This is the method that I use to level my printer bed and keep it level. Welcome to my Ender 3 Bed Levelling method.

When I got my first ender 3 I found it difficult to keep a consistent bed level. This is a problem that many beginners find themselves encountering. You might be inclined to go onto youtube and find a video explaining the paper method which I find a very inaccurate procedure for bed levelling. I am guilty myself of using this method and where it might “feel” correct, there are more accurate ways to achieve a level bed.

I started with the normal bed and the paper method, but I found this method to be inaccurate. So I upgraded to a glass bed and a 0.2mm feeler gauge. I would highly recommend you do too, I actually explain why you should upgrade to a glass bed here if you are interested. The method I am about to share can be done on either a normal printer bed or a glass bed. But be aware results may vary.

Ender 3 Bed Levelling Method

Levelling the bed consists of adjusting the distance between the nozzle and the bed across the entirety of the build surface. The nozzle will be set equally and at the same distance across the bed. This will ensure the nozzle will print the perfect first layer for your print.

Note:

The bed should be preheated before the levelling procedure begins. This is especially if you have a glass bed. The bed will expand with heat. If you don’t preheat the bed, once it heats up for your print the bed will actually be closer to the nozzle.

Now, moving forward:

  1. Autohome the printer nozzle, taking care that the nozzle doesnt collide with the printer bed, you may have to lower the bed fully at the beginneing depending on the height.
  2. Using the printer controls move you nozzle to the front left of the bed.
  3. Use the 0.2mm feeler gauge and place it under the nozzle.
  4. Raise or lower the printer bed using the knob underneathe until you feel slight restistance when you move the feeler gauge.
  5. Auto home after setting the cornor.
  6. Check centre of buildplate with feeler gauge.
  7. Repeat steps 2-5 for each cornor.

Checking the centre of the build plate after each corner set will allow you to see if the centre of your build plate is being set to the correct distance. This is important especially if you have the normal build plate because these plates can warp and the centre may not be where you expect it to be.

The centre of the build plate will change height after each corner is sent, so make sure to check it at the very end. if you are finding the centre is still not set, look at moving its closure by moving all four knobs the same quarter turn until it’s set. I would proceed to check each of the corners again just to be sure.

How to improve the bed levelling process?

Change the Springs on the Leveling screws: The springs that come stock with the Ender 3 aren’t really that stiff. So with any slight movement of the knob or bed, there is a chance of them loosening, which, changes the bed height. You can upgrade the springs too much stiffer ones which will improve the overall stiffness of the bed.

Conclusion

With this process, I have gone from levelling my bed a few times a week to a few times a month. As long as I let the bed cool completely and don’t try to force prints off that is. It is important to let the parts cool completely, any external movement on the bed can change the level.

I hope this wee tutorial has helped. there are many different ways to level a bed, but this is the one that I have landed on myself. it may take you a few tries to nail down this method, but I’m sure you will be able to handle it.
