Manual Leveling VS Auto Leveling Sensor

In 3D printing, the quality of the first layer of printing determines the quality of the entire model. If the first layer is not printed well, the model is likely to fail, leveling is one of the most important factors for model creation, an uneven print bed can cause unexpected problems with the first layer of 3D printing. These result in poor adhesion of the printed model. In some cases, if the nozzle is too close to the printing bed, it may even become clogged.

Therefore, for 3d printing enthusiasts, leveling has always been a very important operation step before the model printing starts, but it is an unavoidable problem for most 3d printer enthusiasts, especially manual leveling of 3d.

The printer takes a certain amount of time each time. Before the automatic leveling sensor comes out, most 3D printers can only use manual leveling at the beginning. Today, let’s talk about some of the automatic leveling Principles, and some advantages of automatic leveling compared to manual leveling.

Now let's take a look at the principle of manual leveling and how it works in general.

For manual leveling, many users might not get used to it and may say it is troublesome, it is still the mainstream leveling method for current 3D printers. For ordinary users, this adjustment method can reach about 0.2mm accuracy, if the accuracy requirements need to continue to improve, you need to automatically adjust the assist level.

But it can’t tell very much with little difference now let’s also take a look at how to manual leveling sometimes and see if it is really troublesome. For manual leveling, there will be always four knobs at the bottom for leveling. This operation can be said to be relatively simple and complicated.

Generally, we will prepare a piece of A4 paper first. Move the A4 paper to four points and level it in sequence. The standard for leveling is that there is a feeling of friction between the A4 paper and the nozzle and it can be moved back and forth. 

How about the auto bed leveling? auto bed leveling is relatively simple to compare to manual leveling, that is, test the distance between the nozzle and the platform according to the 3D printer, and control the Z-axis to compensate for the distance during the printing process, so as to satisfy the level of the printing platform and the nozzle.

However, in auto bed leveling, one condition must first be taken under consideration: rough leveling first. Some users feedback to us that the value of this z-axis offset is sometimes difficult to control, here is the picture that can better show you what is the best position.

Part of the FDM 3d printer can not be automatically leveled in the market. After obtaining the distance between the nozzle and the platform, the Z-axis is always in motion during the printing process, that is, the Z-axis continuously moves up and down to meet the layer thickness and requirements set by the slice. If the platform is out of range, the effect of automatic leveling will basically not be reflected. If the platform is properly adjusted, the effect of automatic leveling can be said to be minimal, and it can be quickly adjusted to the correct position. For users who do not require high model accuracy, they can be adjusted manually to meet their requirements.

For 3D printers with only manual leveling devices, there are already automatic leveling accessories available on the market for addition, and the new automatic leveling function is added. This is good news for most 3d printing enthusiasts. , It shortens the usual leveling time and makes it more convenient. Many 3D printer manufacturers have also begun to develop them to self leveling 3d printer.

They have been equipped with their own 3D printers, which have solved the problem of frequent probes pop up and can not be stretched, and after-sales problems of their own machines difficulties, such as Kywoo touch. Many 3D printing manufacturers are now upgrading their machines with automatic leveling devices to meet the leveling habits of most users.

How Does Auto Bed Leveling Sensor Work?

If your 3D printer supports automatic leveling of the print bed, this normally implies that it has a built-in type or closeness sensor or a switch near the pointer of the nozzle.

As soon as you launch the automatic printing bed leveling process, this sensing unit checks different factors on the printing bed to calculate the range in between the nozzle and also the printing bed at each of these points. It that utilizes this information to determine the real orientation of your printing bed in connection with the movement of the nozzle on the axes.

The printer's firmware proactively utilizes these details throughout the printing process to change the setting of the nozzle as it moves across the printing bed if required. If the print bed shows small irregularities, the firmware makes small changes to the Z-axis throughout the printing process. This makes sure that the nozzle is constantly at the maximum distance from the 3D printer's print bed.

What is the Advantages of the auto bed leveling?

1.Automatic print bed progressing makes it easy to readjust the build surface area for 3D printing without having to reconfigure the whole printer.

2.You gain from a high-precision print result, which can be accomplished no matter irregular heating or a perhaps rounded building board. The sensing units make certain that the print head always moves alongside the structure board.

3.You do not waste time readjusting the printing bed or the elevation of the Z-axis.

4.Even if you're new to 3D printing, automated print bed progressing offers you the simplest experience.

5.Vehicle printing bed leveling makes sure that you can begin printing promptly.

What are the disadvantages of auto bed leveling?

1.The sensing units responsible for automated print bed leveling make the print head heavier.

2.The firmware of the 3D printer might include mechanical mistakes or a defective style that will make it impossible for you to attain an evenly set up print bed.

In inclusion, now 3d printer equipped with auto-leveling will be much Convenient than manual leveling. if your 3d printer now can only be manually leveling, you can buy a auto leveling sensor to give it a shot, you might not want to manually level the bed anymore.
