While the BLTouch is an extremely accurate leveling sensor, there are a few disadvantages to it as well. In addition, if using the BTT Smart Filament Sensor, take a look at our in-depth guide to setting up the BTT Smart Filament Sensor. BTT UPS 24V

My leveling BLTouch is 37mm to the right of the nozzle, and 2mm behind it, so I would put the following settings. You must measure these values ​​to enter on your printer (do not use mine). Most extension cables for the BLTouch are slightly different from the extension cable that came with the kit from Creality. The end that plugs into the mainboard is usually split in two to be compatible with other mainboards. But that’s not bad at all, you just have to make sure that the colors of the cables are plugged in at the right places. Step 2: Mount the BLTouch

BLTouch / 3DTouch sensors are mechanical, so they are not affected by heat, humidity or the type of material on your printing surface. M190 S{material_bed_temperature_layer_0} ; Wait until the heated bed reaches the desired temperature 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. But first, let’s explain a little more about how they work. Moreover, Nema 17 stepper motors operate with two coils with wiring in pairs. Namely, the first pair 1A and 1B move the stepper motor in one direction, while 2A and 2B move in the opposing direction. Easy to Use: This auto bed levelling sensor makes it easier to level the hotbed, which can precisely measure the tilt of the Bed surface. Bed levelling is not a problem anymore.

On the other hand, BLTouch blinking red slowly (more on than off) is a sign that there is an issue with the 5V or GND wire, such as incorrect wiring or wire damage. Follow the included instructions to use the the progisp software to upload the firmware to the mainboard. Comparison would be pointless if micro switch sensor for bed leveling does not include the retraction and deployment method. 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.

Naturally, the PID tuning command for the hotend closely resembles that of the heated bed, with the only difference being the hotend is selected with H1 and adjusting the fan output if required. M303 H1 P1 S220 F1.0 ;P1=100% PWM, S=220C, F=Fan at 100% Alternatively, you could insert the same command into the start G-Code of the slicing software. Further reading BLTouch is a type of electronic component for 3D printer with built-in semiconductor Hall sensor or optical sensor.
