    However, a well-leveled table is extremely important for proper execution of the printout. Bad bed leveling may lead to print not sticking to the bed. There may be gaps in the initial print layer or the layers will be too thin. Filament can accumulate around the nozzle as you print the first layers and numerous other problems.

    Therefore, the auto-leveling sensor can be a great help in this process. Auto bed leveling sensor allows us to create a 3D image of our table and use it to correct our prints. With this solution, the software uses a 3d image to correct the Z axis positions on an ongoing basis e. So much for theory. The sensor will be installed in the Anycubic i3 Mega printer. Unfortunately, this model does not have a direct interface to install this module, so there will be much software and hardware work.

    Software Instalation The default Anycubic i3 Mega software does not supports auto bed level sensor, therefore it is necessary to install open source software that supports such functions. In my opinion, the best solution is Marlin-Ai3M. Those are just a few advantages of this software. There are already three compiled hex files provided. Unfortunately, none of them has BL Touch support enabled, so we must download uncompiled source code version source code. This will open the whole project for us, but we are only interested in the Configuration.

    It is a configuration file for our printer. Depending on what modifications we have already made and what we want to make, we can set it here. Lines are responsible for the type of drivers used in the printer. Change or reverse the motor connector if an axis goes the wrong way. First we need to choose the type of probing. Lines are responsible for this.

    At the end of this article, you can download the hex file I generated and the entire configuration file. Finally, we have to upload the prepared custom firmware to the printer.

    For this we will use the Cura program. We connect our printer with the cable provided by the manufacturer. If necessary, we install drivers. We turn on the cura program. We select generated hex file after about two minutes, our printer should be ready to work. Hardware Instalation After finishing the software part, we can go to the hardware. As I mentioned at the beginning, the Anycubic i3 Mega does not have a built-in support for the auto leveling sensor, so we have some soldering to do.

    To a small printed circuit board located at the top of the trolley holding the hotend. We need to solder two cables responsible for grounding and signal.

    We connect our BL Touch to the newly soldered cables. The black cable is connected to the ground, white to the signal. Once we have it done we can attach the sensor to the trolley. Screw the sensor to the bottom of the model with the next two screws. The last issue is connecting the sensor to the motherboard.

    The three colored cable of the BL Touch need to be pulled out through the upper outlet in the grille and led to the motherboard. This cable must be connected to the following inputs: It is important that we connect our BL Touch in accordance with the above-mentioned pins. In the case of my sensor, the color of the cables was as follows: red — 5v, blue — ground, yellow — signal.

    For me, it was necessary to change the power and ground cables to match the pins on the motherboard. Preparing for printing If everything has been done correctly, BL Touch should undergo auto-diagnosis during start-up.

    This means that during startup, the device should release and retract the probe times. The only thing left for us to do is to use the newly installed sensor. If everything works, we should get an effect similar to the following:.

    Posts 1, Most of us went thru the exact same experience, we were not blessed with a perfect print every time. We had to learn that the first layer height is in a small range that is hard to achieve. Especially when trying to adjust mechanical sensors or switches.

    I found several ways to make this simpler to achieve. One: I created a mechanical proximity sensor slide mount with a thumb screw to be able to adjust these tiny differences in nozzle height, this allows me to turn a thumb screw to make microscopic adjustments to slowly get the nozzle into that perfect height.

    When achieved I can print many weeks or even months before readjusting. Then the nozzle height process starts all over again As the mechanical sensor adjustment is a slow process and requires many tries to get the nozzle into the correct position. This adjustment occurs at the beginning of every print using the LCD control to nudge or baby step the nozzle into place, this process occurs during a skirt that is printed before the model printing begins.

    Three: I use both process along with other mechanical bed leveling techniques to get the bed as close to level as possible then final software Auto bed level.

    As stated I make microscopic changes to the nozzle using the Baby Steps while the skirt is being printed until that perfect height is achieved. Note: I keep track of the distance changed from the LCD to get this nozzle height, an after many weeks of practice have determined this number can be translated into a fraction of how far to turn the thumb screw and in what direction so to more quickly adjust the mechanical proximity sensor slide mount.

    Simple with logical steps that can be made with precise adjustments, when manually adjusting a locked switch, repositioning switch we cannot guarantee accuracy.

    It is not a difficult job to avoid this issue because there are plenty of solutions, but to get the job done perfectly you should have to know about the actual reasons that are causing the problem.

    The major reasons behind this problem to occur include the following.

    As you know that there is not a single problem in 3D printers that cannot be solved. You can get rid of any problem after you have found out the basic reason or cause behind it. There are many solutions suggested by the 3D printing experts and manufacturers to get rid of the 3D printer printing in mid-air problem efficiently without any hassle. Whenever you notice that the 3D printer nozzle is too high, it is recommended to stop your printing process immediately and first try to fix the problem to prevent your prints from damages.

    If you set a different print height but still see that the 3D printer first layer is too high then you should consider implementing one of the following solutions.

    Here we will discuss the simplest and easiest techniques and ways to solve the problem and enjoy a perfect printing experience.

    This will bring up your starting G-Code within your sliced file. I would examine this code and check what is happening with the Z axis.

    G28 is the home position. Reset your settings back to default or to a custom profile that is known to work well. You can also adjust the Z offset by inputting it directly into the slicer. With the change in the Z offset it is recommended to check for the first layer printing settings as well.

    Make sure that the first layer is not set to 0. Try to have a first layer around 0. Bad bed leveling may lead to print not sticking to the bed. There may be gaps in the initial print layer or the layers will be too thin. Filament can accumulate around the nozzle as you print the first layers and numerous other problems.

    1. I apologise, but, in my opinion, you are not right. I am assured. Let's discuss. Write to me in PM, we will talk.

    2. I can not participate now in discussion - there is no free time. But I will return - I will necessarily write that I think.
