Simple Steps to level a 3D Printer Bed ?

Getting the bed of your 3D printer level is a very important step that determines the strength and quality of your 3d prints. A level bed makes sures the first layer of your print sticks well to the build surface, setting a solid foundation for the rest of your print. This guide will help you with the whole process of leveling your 3D printer bed, covering both manual and automatic bed leveling.

How to level a 3d printer bed ?

To level your 3D printer bed, you’ll need to adjust the bed so it’s evenly parallel to the nozzle, making sure of the good adhesion and print quality. You can do this manually using a piece of paper and heatbed knobs or by using Automatic Bed Leveling (ABL) probe.

Importance of Bed Leveling in 3D Printing

Bed leveling in 3D printing is like making a strong  foundation for your house. It helps the first layer of your print to stick well, which is important for the success of the rest of the print. When the bed is properly level, your prints are more likely to come out in good shape and without failing. Leveled bed makes sure the filament lays down evenly on the whole print bed , which is important for both the looks and strength of your print.

Consequences of an Unleveled Bed

If your 3d printer’s bed is not level, you’ll face problems. The first layer won’t stick properly, which will lead to failed prints. It is not just about wasting filament, though that’s annoying. An unleveled bed can cause the nozzle to scrape against the bed, which can damage your printer’s heatbed, Build plate or Nozzle. And if you are still able to print with an unleveled bed, prints that come out will have uneven layers, making them look bad and less strong.

Manual Bed Leveling

Manual bed leveling is all about using hands to level your 3d printer’s bed. Unlike Automatic bed leveling (ABL), this method depends on your sharp eye and steady hands.

Importance: Knowing why a level bed matters is the first step. A level bed means your print’s first layer will stick well, which is important for the rest of the print. It will help you to avoid problems like warping that can ruin your prints.

Gathering Necessary Tools: Well there are rarely any tools required to level the bed but usually, you’ll need a piece of paper or a feeler gauge.

Heating the Printer: It’s a good idea to heat your 3d printer’s hotend and heatbed to the printing temperature before leveling the bed. This way, you are prepared for any expansion that happens when the bed and the hotend heats up.

Checking Initial Level: Home your 3d printer by click on XYZ Home, Auto home button etc or any button like that in your 3d printer then start moving the nozzle to each corner of the bed and check the gap between the nozzle and the bed using a piece of paper. The paper should slide with a bit of resistance.

Adjusting Bed Screws: If the gap is too big or too small, use the heatbed knobs and twist them until you get the right gap. You have to find a fine balance, you don’t want the nozzle too close or too far from the bed.

Checking the Center:  After you’ve leveled the corners, check the center of the bed. If the nozzle to the heatbed gap is too small or big, you might need to go through the leveling process again or check for a warped bed.

Re-checking: After adjusting, go back and check all areas of the bed to make sure they stayed level. It might take a few rounds of adjustments to get the properly leveled heat bed.

Running a Test Print: Now, run a test print to see how well the first layer sticks to the bed. Look for any unevenness, there might be some areas or corners of the bed that need to be properly leveled.

Fine-Tuning: Based on your test print, make any final adjustments to the bed level. This might include slightly turning the heatbed knobs to achieve that perfectly leveled bed.

Maintaining a Level Bed: Now, your bed is leveled but do check the level of your bed once in a while, especially if you move your printer around. Over time, your bed may become unleveled.

Automatic Bed Leveling (ABL)

Automatic Bed Leveling process uses a probe which is a device that mounts beside your 3D printer’s nozzle, and used to measure the distance between the printer’s nozzle and the bed. This measurement helps in adjusting the bed level to make sure that the first layer of the print sticks well to the bed. The probe sends signals to the printer’s firmware, which then makes most of the important adjustments to the bed level or provides data to the user to make manual adjustments.

Types of Probes

Touch probes: These probes work by physically touching the bed and measuring the distance between the nozzle and the bed. Touch probe touches the bed, it triggers a signal that is sent back to the 3D printer’s firmware to z offset adjustments of that point.Touch probes have the most accuracy but can be little slow since they have to touch the bed at multiple points.

Inductive Probes: Inductive probes work by detecting distance between the probe and metal surfaces and are mainly used in printers with a metallic bed or PEI Sheet. Inductive work by generating an electromagnetic field and when that  electromagnetic field interacts with the metal bed, the probe sends back the signal to the 3d printer’s firmware. Great thing about Inductive probes is they are fast and don’t require physical contact with the bed.

Capacitive Probes: Contrary to inductive probes, capacitive probes can work with any type of bed material from Platic, glass to metallic etc. They also measure the distancebetween the probe and the bed then send signals back to the 3d printer’s firmware. They are useful, but might get affected by temperature and humidity changes.

BLTouch: It’s a most populart touch probe that gives high accuracy readings. BLtouch or its cheaper alternative 3D touch can be very precise as well as easy to install, and works with any bed surface and they are also a type of touch probe. It’s a popular choice among 3D printing enthusiasts.

Setting Up Auto Bed Leveling (ABL)

Choose a Probe:Select a probe compatible with your printer and bed material. Your choice will affect the accuracy and ease of the leveling process.

Install the Probe:Follow the instructions provided with the probe to install it on your printer. Make sure it’s properly attached properly with a 3D printer and it should not be wobbly.

Update Firmware:Update your 3D printer’s firmware. You might need to download specific firmware or eidt or add new lines of code to your 3D printer’s current firmware..

Calibrate the Probe:Calibrate the probe to achieve accurate readings. This includes setting the probe’s offset, which is basically the distance between the probe and the nozzle in the XYZ axis.

Test the Setup:Run a test print to make sure the probe and firmware are working properly and providing accurate reading and according to the print result you can make some z offset or manual adjustments to improve accuracy i.e if needed

Starting Auto Bed Leveling

Start ABL: Start the auto bed leveling process through your printer’s control interface..

Follow On-Screen Instructions: Follow any on-screen instructions provided by your printer. This might include waiting while the probe measures different points on the bed.

Adjust if Necessary:If the ABL system provides feedback suggesting adjustments, follow through with these adjustments to get a leveled bed.

Run a Test Print:Once the ABL process is complete, run a test print to make sure the bed is level and the first layer sticks evenly and well.

Fine-Tune:Based on the results of your test print, make any necessary fine-tuning adjustments to improve the bed level.


Getting your 3D printer’s bed properly leveled is the most important step in printing good quality prints. You can either do it by hand or install and use automatic bed leveling but, knowing how to level the bed  is important. follow the steps we talked about, and you’ll see your prints get better. Remember, a little patience goes a long way in 3D printing.


How do I manually level my 3D printer?
