BLTouch is controlled by hall effect, providing high precision. Thus the bed material can be freely selected. The process is essentially the same on the Ender 3 Pro, except that you need to save your settings after adjusting the Z-offset properly. Why is a BLTouch recommended? – I recommend the BLTouch because it uses software to make mini movements as needed to account for the build plate not being level or having warps. Many 3d printers have warped build plates that will impact prints and can only be corrected by being replaced with a flat one or an auto bed leveling device like the BLTouch. On the other hand, the end G-code does not require anything special for the BLTouch to function correctly, but we recommend adding the M400 (Finish Moves) command to ensure that all actions are complete before the end G-Code routine starts. As you can see in this image, the BLTouch / 3DTouch leveling sensors have two connection cables. One with three pins and the other with two pins, which will be the ones we will need to connect to our electronics.

Plug the cable into the designated space for Z-sensors in the motherboard. Depending on which extension cable you use, it is either one connector or two that you have to plug in. The result is the same: the colored cables must be in the same place (see picture).The self-test option will repeatedly deploy and stow the BLTouch pin for several cycles. M280 P0 S120 ; Reset If you’re using the official firmware supporting BLTouch from Creality, you shouldn’t have any issues using Octoprint with the BLTouch. It should work just fine, so long as you update the slicer settings with the G29code. Main Features: The main functions and controls of BLTouch are the same as the usual auto bed leveling sensor, which consists of an RC servo and microswitch. Thus, BLTouch can be applied on almost every board. Alarm : The AI will flash the LED indicator if a problem is detected during a self-test or operation. The 3D printer can read the BLTouch alarm signal, and according to the alarm status, it can stop and pause the 3D printer with preset G-code, as well as operate the BLTouch release, stow, etc. Please do not ignore the alarm signal and make good use of it. It can keep your 3D printer and BLTouch safe. As executing the G28 command disables bed leveling as a side-effect, running the G29 command after G28 ensures that both the auto home and the bed leveling (with BLTouch) procedures are successful.

If you have read the complete article, I congratulate you. It would not be surprising if he had left me something in the pipeline, if so, do not hesitate to notify me in the comments at the end of the article Install and configure BLTouch / 3DTouch in Marlin 2.0.x (MKS Gen, SKR, Anet A8, RAMPS). This connection is similar, but you must make sure that you have the jumper activated, so we will make sure that the level sensor reaches the 5v. necessary (very important). The main difference between BLTouch and other auto-leveling methods has to do with the kind of sensor used. Other sensor methods

BTT SKR Mini E3 Setup Complete

Without a doubt, having three PWM controllable fan outputs on the SKR Mini E3 V3 is perfect for using thermostatically controlled fans to save on both noise and power. While the BLTouch is an extremely accurate leveling sensor, there are a few disadvantages to it as well.

Before you get started with modifying your machine for the BLTouch, you’ll need to plan for the following: As with everything else in the 3D printing realm, the BLTouch can come with problems of its own at times, with the issue of a red blinking light being the most commonly talked about one in the community, which will be our topic today. Wide application： Compatible with ABS, PLA, glass, metal, plastic, and all materials.Support more filaments and apply to every control board of 3D printer Although installing a 3D printer mainboard can be daunting for those new to the process, especially the electrical side. But don’t worry, follow along with this setup guide for the SKR Mini E3 V3, and it will take you through the process step by step. The odd bit of wiring Although, the alternative method requires some firmware changes. However, it does tend to fix some issues. NeoPixel DCDC Red Jumper placed on left and middle pins enabling DCDC module

The BLTouch is one of the most accurate and reliable sensors available, so it’s no surprise that a few manufacturers such as MakerGear and CraftBot use this device on their high-end machines. M109 S{material_print_temperature_layer_0} ; Wait until the extruder reaches the desired temperature

Other auto-leveling methods use an optical or proximity sensor to determine any inaccuracies in the slope of the build surface. Those methods have the benefit of being able to adjust while the printing is happening. But have the downsides of not working with certain bed materials and being expensive to repair. BLTouch As soon as the probe pin reaches the stow position by the solenoid current, the permanent magnet at the top of the probe pin is attached to the ferromagnetic core (hexagonal wrench bolt), and the position of the probe pin is maintained without additional current. Remove the LCD connector out of its housing to gain access to the pins next to it. The LCD connector is the wide strip of gray wires.

To start, let’s talk about why it’s vital to ensure that the BLTouch activates and levels the bed after the bed heating process is complete. Specifically, within RepRapFirmware (RRF) and the Duet3D DWC, macros are a set of instructions that send commands to the 3D printer’s mainboard. Moreover, written in G-Code macros help to speed up the everyday use of the 3D printer. Whilst saving time looking up commands that you might otherwise forget. Now that the correct firmware is installed, you have set the Z-Offset and everything is mounted correctly, you can start the automatic print bed leveling. With the new firmware, you will find a new “Leveling” button in the menu.
