Hall effect sensor tutorial - 3D printer end stops
Вставка
- Опубліковано 14 кві 2014
- This video shows how to use linear hall effect sensors to build end stops for 3D printers. The end stops are used to calibrate the absolute position of stepped moving parts. The end stops built in this tutorial are using magnets to detect the proximity of the magnet. The distance can be adjusted using a trim pot.
If you are interested in more practical applications using this sensors see my organ pedals project:

Great vid! Even 9 years later :-) Brilliant music too.
Thank you! I wish I had this 40 years ago when I was early into electronics and wanted to make a CDI ignition for a motorcycle that had contacts. I can see how this would easily let you do what all the Japanese MC makers were touting as the greatest thing ever. I might still make one anyway. Great extra info about the PCB making too. makes the project so professional looking!
Thanks again.
I love the schematic that updates as you build the circuit. Nice work
Actually best "innovation" in making tutorial videos. Keep it up.
Hey! I'm waiting for more of your videos! I love the way of your explanations. Your tutorials are being very useful to understand things that I don't in the University. Sad but true! Hope to see you soon mate!
You sir have mad skills, and thank you for this tutorial. The Information presented was very clear and concise.
You did a very nice job with this video. I think the inlays of the datasheets are very nice.
Hello from france !! Clear tutorial and explanation :-)
Hope to see other subjects soon !!
Thanks... that was really useful... I'm working on a hall-effect RPM meter and this video just popped up in my suggestions.
Thank you! Just just helped me tremendously to understand what can I do with them!
God bless you for passing on your knowledge. excellent contribution.
This was a very helpful quick tutorial Thank you.
You are like Steve Vai in electronics. Make everything to look so easy. :)
best tutorials i have seen so far (Y) (Y) ...respect your ambition bro :)
Your tutorials are always good.
Excellent tutorial. Thank you for sharing.
Thanks for very good explanation of the solution
This is so smart! I would suggest though getting a linear hall sensor not as an endstop but as a bed leveling sensor. By moving the sensor to the print head you get the added benefit of being able to use it for bed leveling.
not sure if they don't drift at different temperatures... just like in curie point etc
bitluni's lab look up 3Dtouch bed leveler sensor. It uses a small metal plunger that freely moves up and down and uses a hall sensor to read when it is pushed up by the printer bed to register the bed height. I’ve been using it for a a few months and it’s temperature invariant. It doubles as a z end stop and a bed leveler.
Congratulations on the tutorial!
This circuit is very close to the Bltouch used for leveling the hot bed of 3D printers. Have you come to test the accuracy to prove it is usable as a hot bed leveler?
So, you could run the output from either hall effect sensor board to a MOSFET gate driver (to power a MOSFET) to power an inductive load.
First of all, thanks for your very good video! When comparing connections with the latch 1881KUA I saw that there a 10K resistor must be in between Vdd and out. Is it not necessary here?
Excellent stuff!
Can you work with TCD Doppler and thickness gage transducers? I only understand basic principles but I'm not really into electronics. Do you think you could help me with a little project? I need to lineup and control 3 sensors (TCD, ultrasonic thickness gage and Hall) using a controller/pcb, and you make it all look so easy.
Well ...Yes...Nice....
Good Luck
Latvia.
Great tut.
sir, nice explained thanks
well done just brilliant this could be the future just by harness not the direct heat of the sun or burn matter left over by it, but the magnetic field energy which is present energy
wonderful tutorial :D
Great video thanks
Good video! Help heaps!
I used halleffect endstop in my voron and the problem is when the temperature inside the chamber is getting hot the distance of the magnetic area between the magnet and sensor will change, then the Z stop position will change too.
Is lower resistance needed for a longer distance of detection
one question tho, by using an amplifier, you converted the hall effect sensor from linear to switch. so why dont you just simply use a switch hall effect sensor? it will give u 5v if magnatic field is detected and 0v otherwise
Hi) If there is a supply the circuit works fine without arduino too, does not it?
thanks sir for this idea
Sorry hi do you sell this modules. I am looking to operate 12v led strips about 2m. Thanks
thank you 😀
What part number Hall effect sensor was used? Thanks.
Hello! very interesting video. what type of potentiometer are you using? name/brand? I just need to adjust the capture distance of my Hall sensor which is too far away. THANKS. If anyone reading my comment can respond to me that would be great! thank you as well..
super tutorial
Thank you.
what program did you use to create your PCB schematic with?
How far away from magnet can you get it to work ?
Excelente!
Hy kann ich opv und hall an der selben Spannungsregler setzen ?
awesome ..i like it ..
Thank you :D
Very good 🙏🙏🙏🙏
perfect
Nice work!! Would this give good resolution for a trigger set up? Want the magnet on the trigger and as you pulled it closer to the sensor it could give an analog out to a control and than the controller would convert to a PWM circuit to control an ESC. Want some range because it will be on and ESC. Even like to build some expo curves where it isn't as sensitive on the first percentage of the pull. What do you think?
Sounds good.. then you can connect the linear hall effect signal directly to the analog pin... could work.. what kind of project are you doing?
Wanting to making a transmitter and a receiver with an Arduino Pro Mini and the nRF24L01. Do them in a pair. The trigger can be open to water hence why i need the hall effect sensor and a magnet, the other compartment needs to be water proof.
Just wondering if this hall effect sensor will give enough resolution want the trigger to have some play in it
have you tested the reliability with these sensors? what distance can you get repeatedly?
I am very interested to see a repeatability/accuracy study using this technique. And by accuracy, I mean with a dial indicator to get a true value result. It seems to me that if home position is to be accurate, you need to repeat to within only a few thousands of an inch. (.1 mm)
I am interest about the step of make the PCB board.
could you told me?!
thank you~
it's called toner transfer. you need access to a laser printer and some glossy paper. you transfer the toner to uncoated PCBs. I am using sodium persulfate to etch. see this vid where I already explianed all steps in detail:
MIDI organ pedals - 04: The cursed multiplexer board
Magnificent ;)
can you please add the schematic and parts list to this video?
Also will this work for detecting current draw on an AC circuit?
which software did you use for building the pcb
DipTrace
Just digital one without any boards is more enough. The magnet should pass the sensor for more accuracy. Not approach the sensor.
Hi do you sell this

bitluni's lab Great video, as always! It is scary how much our interests overlap! Mine are only interests at the moment, still just watching and learning, but you seem to have a video about everything I was looking for! Arduino, BT LE, magnetic sensors... You even have stuff about electronic audio which I used to be very in to!
And what's really scary is: why aren't you a millionaire?! I understand you're having fun, but with so much knowledge and talent I just hope you're making a nice living. If you're not what hope is there for me...
Really appreciate that you like the stuff.
To be honest, currently I don't earn any money with all this. It's more like a hobby and it's lots of fun. Maybe one day I have enough subscribers to cover at least my costs :)
ach, diesmal spendierst Du sogar einen Widerstand fuer die arme LED. kein Wunder, dass die Kosten ausufern.
optical sensors will be better for this purpose
