## Features

- High Precision: The accuracy difference of the table is very small, about 0.005mm. The 3D printer automatically detects the surface of the bed, and automatically adjusts the perfect distance. The stroke is up to 1.6mm longer than V2.0
- Wide Application: BLtouch auto bed leveling sensor compatible for Creality 32-bit V4.2.7 and BTT SKR MINI E3 V3.0/Octopus/Manta/SKR V1.4 Turbo/SKR Pico/SKR 3 Series, MKS Gen L board. Sutable for Ender 3/Ender 3 V2/Ender 3 MAX/Ender 3 Pro/Ender 3S/Ender 5/Ender 5 Pro/CR-10 3D Printer
- Smart Functions: Featured with self test, the push pin is operated three times to test when the power is on. The LED light blinks if a problem found on a self-test or on an operation
- Warm Notice: BLTouch auto bed leveling sensor must be installed perpendicular to the ground. If BLTouch push-pin can't be perpendicular to the ground, BLTouch will send wrong signals
- After-sales Service: The manual and installation instructions have been uploaded to Github, If you have any problems during use, please writer to us at the first time, we will give you a satisfactory solution

## Customer Reviews

### ⭐⭐⭐⭐⭐ Running on SV07+
*by F***D on May 21, 2025*

Works great, way more accurate and consistent than my inductive probe with the bed heater on. Printed a bracket out of ABS to mount it to the toolhead.

### ⭐⭐⭐⭐⭐ Reliable and easy to install
*by B***N on April 15, 2025*

Works great! Super easy to configure and calibrate

### ⭐⭐⭐⭐ great product, instructions for 32 bit (silent board) are inacurate!
*by Z***N on October 28, 2020*

BLtouch is a great product but instructions for 32 bit board need to be updated. I emailed the seller my discoveries who in turn will notify the ANTCSLABS.I have spend many hours trying to figure out this setup, I ended up figuring out that instructions are quite misleading and they would drive you off the wall.first of all, Creality BLtouch kit works fine, as far as hardware installation, but configuration of BLtouch on 4.2.7 motherboard is grossly inaccurate.Here is what I discovered by trial and error and watching bunch of youtube videos, many of them did not quite cover the topic correctly.First of all, you will need an micro SD card to save the settings on 4.2.7 motherboard, there is not much room left on EEPROM once all of the features are enabled and you will need to save them to micro SD card or when you power off your printer all will be lost. You will need to re-calibrate the Z settings again. If you forget to punch in Z offsets if the printer was powered off you will be printing a few millimeters up in air. Don't ask me how I know./// How to configure BLtouch after the device is physically installed and wired up///==================================================================Unplug the USB cable if connected to the computer, this prevents the 3D printers receiving the power to its motherboard.Verify BLTOUCH operation and correct installation==================================================================Verify that BLtouch is working correctly by moving the nozzle assembly at least 150 mm above the bed. We will issue auto home command and we need some vertical space so that can turn off the printer power if BLtouch is not stopping downward movement when its probe is touched.Via the printer menu select Prepare -> auto home – printer will start the auto home process and the nozzle will start moving down and BLtouch will extend (lower) its probe.As the nozzle assembly is moving down gently touch the BLtouch probe, the nozzle should stop, then resume downward movement. Touch the probe again for the second time and the nozzle will stop moving permanently. That means that BLtouch is wired correctly and it will stop when the probe touches the bed.Please note: Be ready to turn off the printer power if when touching the BLtouch probe the nozzle is still moving down! In that case you need to check the Bltouch for correct wiring to the motherboard.How to calibrate the Z offset==================================================================Via the printer control knob do the following steps:Select ControlThen restore failsafeAnd store settings.This erases any settings that were previously configured so we start with a blank slate. This is a very important step! If some old Z offsets are still in EEPROM and you start to configure printer you could potentially have the nozzle hit the bed because of old Z offsets were not erased. So, restore the settings to failsafe!note: make sure you have the micro SD card inserted.Auto home the printer==================================================================select prepareSelect Auto home and wait for process to completePrinter will auto home where it thinks the Z axis is. Please note; now there is a few millimeters difference because BLtouch is a few millimeters above the nozzle. This is by design to prevent BLtouch needle to hit the printed object.That is why we have to measure that difference and write it down to be used later.To determine Z offset==================================================================select Prepare,Then move axisThen move ZSelect 1mm and start moving the nozzle down towards the bedWhen you get close to the bed change to 0.1 mm incrementsInset a sheet of A4 paper on print bed (paper is 0.2 mm thick)keep lowering the nozzle via “move Z” slowly with one hand and keep moving the sheet of paper back and forth until there is slight resistance with other hand.You should be able to move the paper back and forth but with slight resistance.Now, stop and write down the value. The value in this image is my value, your value will be different!This will be a negative value somewhere between 2.5 and 4 mm as BLtouch probe is typically that much higher in relationship to the nozzle, and this value varies from one printer to another.This is the value that we will need to input into Z offset in later steps.To prevent accidentally scratching of the bed with the nozzle select prepareThen auto homeConfigure probe Z offset==================================================================select controlThen bed levelingThen probe Z offsetAnd put the value that you have written down for Z offset that you measured in previous steps.The value will be in negative (minus) so for example, -003.2 mm)The value should be typically between 2.5 and 4 mm with original creality Bltouch bracket.Finally, select store settings to save your Z offset!Exit the menu to the top and then verify that settings are correct for Z offset!Your value should be there!Bed leveling==================================================================Select controlThen Bed levelingThen select level bed The process will probe 9 pointsOnce that is done auto leveling is completed.Modify Cura settings for BLtouchIn Cura –select settings -> printer -> manage printersClick on machine settingsAnd add under Start G code:G29 ; (Auto Level / BLtouch mesh)M500 ; save the mesh EEPROMClick close and close again.Do a test print from cura!adjust the Z offset if neededgood luck!
