ANTCLABS BLTouch : Auto Bed Leveling Sensor/To be a Premium 3D Printer (With 1M Extension Cable Set)

Product Information

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

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. A simple command to disable all of the stepper motors. Additionally, if you wish to disable a specific motor/s, add the axis after the M18 G-Code command. For example, M18 X E0 would disable the X-axis and the first extruder motor. M18 ; Disable all stepper motors Extruder steps calibrationIn my printer I use a leveling function available in Marlin 2 called BABYSTEPPING. This function allows me to calibrate the height of my leveling sensor in the center of the bed once with a sheet of paper. 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.

Alternatively, you could insert the same command into the start G-Code of the slicing software. Further reading Since there is no spring inside the solenoid, BLTouch is a very simple, safe and innovative product that can achieve its purpose with very little current and short control time, unlike general solenoids when deploying or stowing a detection pin. BLTouch with extension cable(We use the latest version (V 2.0), which Creality supports directly with its firmware update.) Since the Creality Ender 3 and Ender 3 Pro printers don’t include a bootloader, you’ll need to plug the ISP Cable and adapter to your mainboard. Refer to the image to see how this works. Sadly with so many stepper motors on the market and no set standard on their wiring, writing a guide becomes near impossible. Instead, use the diagram above to match the pairs (1A & 1B, 2A & 2B) of the stepper motors to the mainboard. If you require further assistance, I suggest reading our Stepper motor wiring guide, which details three easy ways of finding the paired/phased connections of a stepper motor.

Likewise, thermistors are not polarity sensitive. But for the printer to function correctly, they need inserting into their corresponding connections. Moreover, the heated bed thermistor plugs into the THB connector and the hotend thermistor into TH0. Although the Creality Ender 3 line of printers don’t ship with a filament sensor as standard, many like to add one to their 3D printer. However, because of the many varied options available, it’s hard to include them all. Instead, the above image and below table shows the wiring orientation for the E0-STOP (Extruder 0 Filament Runout Detection) on the BTT SKR Mini E3 V3 3D printer mainboard. Signal (White)
