 Product Description

Genuine BL Touch bed levelling sensor from Antclabs.  This sensor can be fitted to most 3D printers to add auto bed levelling to the printer.  All you will need are 3 extra pins on your controller board to drive the sensor.

How the sensor works is it has a metal pin which extends lower than the nozzle when the sensor is required to measure the bed.  Then the printer probes the bed.  As soon as the pin touches the bed it retracts and sends the signal to the Z endstop switch on the controller board and the printer knows height of the bed at that point.   This sensor measures the bed mechanically, so it is not effected by the type of material used as printing surface, bed temperature or metallic / non-metallic bed.

This sensor has superior accuracy over other sensors on the market and comes in a neat small package.  Don't be fooled by cheap imitation, if it does not say BL Touch, it is not a BL Touch!

The unit includes mounting screws and springs as will as connectors and pins to extend the cables to the desired length.

 Product Reviews

  1. Awesome sensor

    Posted by Andre Steyn on 11th Dec 2019

    Works perfectly. Takes a little fiddling with Marlin but there is a lot of help on YouTube

  2. Great on My CR-10s

    Posted by Unknown on 28th Sep 2019

    I am very happy with this upgrade. Works well with Octopi, Marlin 1.1.9 and my CR-10s. This and a new glass bed have made my first layers perfect.

    Was easy enough to install following some tutorials. Just remember You will need to have cables ready to extend from the bl touch to your control board as the cables on the bltouch are only a few centimeters long as well as print a mount for your printer to attach the bltouch.

  3. Best Ender 3 Upgrade

    Posted by Marius Kruger on 11th Sep 2019

    This is probably the best upgrade that anyone can do for a Ender 3 Pro. Excluding a main board upgrade off course

    I would recommend this any day

  4. Works great

    Posted by Hannes on 4th Jun 2019

    using it on my first auto leveling printer and its such a joy to work with. have done quite a few prints and haven't had the need to calibrate anything yet after initial setup.

  5. Great product

    Posted by Unknown on 7th Mar 2019

    This is a genuine product at the best price works perfectly.

  6. Works, but Marlin 1.1.9 need regular Z-offset adjustments

    Posted by creatron on 25th Dec 2018

    I have two of these products, and they seem to work quite well, however for some reason the z-offset need adjustment over time, and I cannot get to the root of the problem, one also need to re-adjust the z-offset if you change from PLA (60) to ABS (240), but this could be a printer problem. The CR10 4S glass bed (400 x 400 mm) cannot be utilised without this bed leveler as the bed warp up to 0.37 mm, so It does work, with BLTouch you can really print large objects. This works far better than the Chinese clones, as they are useless, do not even considering buying the cheapies, the pin fall during a print and destroy itself and the printed object, I have three in the dustbin, and none lasted more than 8 months. All in all a 'must have' for larger wrapped beds.

  7. Awesome product

    Posted by Brinco Neethling on 6th Dec 2018

    I use this with my DIY Prusa MK2S based printer with a MKS SBASE 1.3 and this has really taken the effort out of setting up my printer. Great upgrade!!

  8. Worth every cent

    Posted by Luan Steyn on 21st Nov 2018

    Works great with minimal setup.

    Comes with everything you need.

    Would definitely recommend above capacitive or inductive probes

  9. Works exactly at is says it does

    Posted by Mike on 1st Nov 2018

    Works exactly at is says it does and it is the genuine part not the nasty unstable knock off

  10. If you are at war with your heat bed!!!

    Posted by Rhaine Knox on 12th Feb 2018

    I love this product, This auto level probe for your 3d printer may just save you hours of tedious levelling.

    Attaching the BL Touch sensor to your print head – be it a cartesian or a delta doesn’t matter, there are mountings available to print.

    Controller being a ramps, sanguinololu, smoothieboard – it doesn’t matter the BL Touch will interface with them all.

    Simple to install, only two connector to attach. one for servo and one for level sensor.

    Easy to program, coding supplied, just copy and paste. Save and use.

    This addon will save you time, precious time that can be used for printing.

    A visual indicator shows the probe working, in self test mode and when touching the bed. If there is a problem then an alarm signal will show you quickly there is a problem.

    With an automatic bed levelling probe you have mechanical moving parts reliant on the operation of a servo, with the BL Touch there is no servo, just a solenoid, hall effect ic and a tiny computer.

    Very little to go wrong.

    Giving you the peace of mind that this is one thing you will not need to worry about.

    Is it accurate – it has a standard deviation of 0.005 better than the micro switch and servo, with a standard deviation of 0.3. Only the optical sensor comes close, but you are limited on what build platform you can use.

    With the BL Touch sensor it doesn’t matter what build platform material you use, aluminium, glass, pei sheet, buildtak, wood it doesn’t matter. Due to the fact that the probe actually touches the platform, It will not get confused.

    At 10g this probe will not slow down your delta printer by adding a lot of weight to the effector.
