BLTouch - Auto Bed Leveling Sensor - Antclabs

I recently installed this new sensor. I am getting repeatability with a maximum of 0.04 mm which in my opinion is excellent. Most repeated readings of the same spot are within 0.02 mm. Activation force is extremely low. It is a bit of a pain to set the sensor up because the height has to be 'just right'. Part of that falls on me as my mount wasn't easy to adjust - not something I can blame the sensor for. There was a generous amount of extra hardware bits included - nice touch. Documentation - what documentation :) Setup instructions are found via the web but no hookup instructions were available for a Creality CR-10S. A direct request for assistance from the manufacturer did not solicit any help! I did get things hooked up eventually but I would rate customer support as lacking!

Easy to setup, documentation is online and easy to setup with most printers. I've got one on my X5S, CR-10 and Little Monster. Super happy with them, I could use mechanical or peizo, but I'm setup with what I have now and with glass, it's easier than other methods like capacitive or inductive leveling.

Wiring up my BLTouch to my SmoothieBoard took a couple of tries — the wiring diagram on the manufacturer’s website is one picture with no helpful text. I ended up having to scour the rest of their website to find out what the wire colours meant, and then decipher that, yes, all 5 wires need to be connected. Once I got it working it’s great. I’ve ordered another one, for my older printer.

I couldn't get the level right for my first print, and now I'm printing like a pro. Well, not quite, but my Folgertech i3 printer is printing pretty awesomely.

I was manually leveling my bed, with this and a proper calibration no more leveling necessary, I can put a bare glass for TPU, one with PEI for my ABS prints and not have to worry even if the thickness isn't the same. This isa great quality product.

Best product to avoid bed leveling problem.
