NOTE: If you get "not in sync" or "sketch too big" errors during firmware flashing, please watch my video about how to fix these problems here: kzfaq.info/get/bejne/iLd5nN2J2cydn6M.html

Good tips. I never went into such depths for precision. Knowing this when I got my 3d printer would have saved me from so much crashes.

hey Mate, Thanks for the great video guide. It was very useful for the situation that I had to deal with. You got 1 more subscriber. Please keep the videos rolling. Cheers and Happy New Year!

Thank youuuuu!!!!!!! Helped a lot!! Really nice tutorial

Best tutorial ever, Thank you very much.

Perfect thanks for your video.!

I got error with uploading sketch twice. I cycled the anet power and tried a 3rd time and it worked. Thank you sir

good description for this sensor,I need to ask you if u have a configuration for anet a8 with auto bed leveling for the new marlin 1.1.9,because me I use skynet 3d,plus help me to fiind one

Hi, thanks for this - although i believe this is slightly outdated now that Marlin 2.0 is out.

I think you should have more Subs because the quality of this video is great!

CrossLink, your videos are the best. I was about to give up on my A8 until I found your channel. Extra points for the "girl from Ipanema humming". Quick question: Is anyone getting a RIGHT_PROBE_BED_POSITION is outside the probe region error? TIA

Thanks dude helped a lot!!!

Thanks for the video. I was wondering why you didn't copy the Configuration_adv.h file from the Anet 8 example folder as well? And where can I find the list of changes you made to the configuration file?

@crosslink Thank you for your amazing video. I was able to install the sensor, compile and upload your firmware. The sensor is working (red light) but it has nearly the same distance to the bad as the nozzle. When I am trying to start the Auto Home procedure the light of the sensor changes to red, but the nozzle still wents down unitil it crashes into my glassbed. So I was enforced to switch off the printer. I am using Marlin 1.1.9.1 with your configuration.h. What am I doing wrong. Thanks for your advise.

Can this be done for the A8m(dual extruder) as well?

Hey, I saw on Your newest videos with Anet A8 that You have different sensor? Which one is better?

Do you have a video showing where to plug the sensor into the motherboard? I purchased the one on your list with the 3 wire plug for a Anet A8 already installed on it..

Thanks for this video. It was incredibly helpful getting me to a place where I can square up the bed to the print head and actually print. But, could someone suggest why my printer doesn't start a bed leveling calibration after adding G29 to the start code? The G29 command was placed after the final G28. Still no love. I really need help.

Thanks for a video I have installed capacitance sensor (LJC18A3-H-Z/BX 1-10mm) but i found it not much accurate each time i need to adjust z prob offset. I read on internet this sensor change reading due to humitdy and temprator change so each time it come with diffrent number I am thinking to move back to manual meshbed leveling.

Great videos! You are very clear and precise on step by step instructions. Look forward to continue following you. I have been printing with my Anet A8 for years now. Recently just upgraded to Marlin 2.0.7 to enable auto bed leveling. The issue I am having is when I do an AUTO HOME, the nozzle goes to the center of the print bed instead of the sensor. In turn, when the bed leveling sequence starts, the sensor is off the bed for the first probe spot. The sensor is working and will set Z height correctly if I don't run G29 for a print, but I need to manually adjust to level the bed still. With a G29 command, the sensor is off the front side of the bed and the nozzle is where I want the sensor to be. During an AUTO HOME sequence, should the nozzle or probe be in the center of the bed if I have the offset set in the firmware? I think this is my issue. Prints I start now are still centered as long as I don't use G29. Equipment: Anet A8 with original mainboard v. 1.5 Z sensor is a inductive proximity sensor. Software: Marlin 2.0.7 (newest release as of 10/5/2020) My sensor is 74mm in front of the nozzle and centered left/right. I have my offset to nozzle set to (0,-74,0) Settings I have set: define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN define FIX_MOUNTED_PROBE define NOZZLE_TO_PROBE_OFFSET { 0, -74, 0 } define AUTO_BED_LEVELING_BILINEAR define LCD_BED_LEVELING define Z_SAFE_HOMING In configuration_adv.h I have set the first probe location to be 25,25 from zero. The nozzle goes to 25,25 for the first probe spot, which does not work. I appreciate any assistance I can get on this as I am not able to activate auto homing until the offset issue for the Y is corrected.

Is there enough firmware storage on the A8 plus when using Marlin 2.x to have a autoleveler and filament sensor both working?

Hello Daniel, thank U for many helpful tips and videos. But how do you wire the sensor? Which wire goes to which pin of the connector?? Please tell and the Video would be nearly perfect in my opinion. Alex

Hi! Cool video My 3D printer is old and uses an enclosed electronic board (Gen7Br) So, I would like to use the LJ12A3-4-Z / BX proximity sensor only with Arduino. Making an analog reading to measure distance through the Monitor Serial, can you help me with the code?

Great Tutorial. Thank you very much. 1 problem though in my config. I used your config + tutorial(I have a Anet A8 with same inductive sensor, offset X=-39, Y=-1). But the problem is that it will start printing from 0,0 in the center, not from the real 0,0. So if I have the gcode to print in the lower-left side of the board, it will in practice print this from the center instead of 0,0(lower-left corner) Do you know why? Any help is welcome.

My Anet A8 is working great now. I tried to add a BLTouch and found that The Old Fashioned bed leveling with a piece of paper works the best for me. I level the bed every 4 or 5 prints.

So what kind of signal does the probe you're using send? Is it the same as what the normal z stop sends? I mean to say could you just mount your normal z stop on the extruder and follow the same steps?

Hello I purchased the sensor in your description from Amazon but I am having two issues. 1) the sensor doesn't appear to function on the supplied 5v. I tested on 12v and the sensor powers on and functions. But on 5v there is no power indicator or closure. 2) Since flashing marlin my. Xzy flash 0 and ? Is this bacause I haven't been able to home. And level yet?

Hey, thank you for the great video!! Any suggestions how I can get the NOZZLE_TO_PROBE_OFFSET working with the Marlin 2.0.7.2 firmware with the Anet A8, the printer follows the probing - coordinates with the nozzles... Thanks!! :-)

How would I wire this with a control board like the ender 3 with only 2 wires for the end stops

Hello and thank you, I have my Z axis rising instead of going down when I press on "auto home" .... an idea? thank you in advance

Hi Crosslink. I’m having an issue where I was able to change the Z-probe offset on the User Interface only one time. I can no longer change it. I’m not sure If I accidentally changed a setting that locked it or if it is just a bug. Do you happen to know of anyway to fix this? I believe I am using Marlin 2.0.3.

I've got a question about setting the z-probe offset. In the marlin config.h file it has the example layout of a printer and tells you which direction gets you a positive or negative offset. It says the following: Z offset: -below +above [the nozzle] which makes me think (based on the example diagram) that a negative offset actually implies that the sensor is below the nozzle, which obviously isn't possible. TLDR; shouldn't the offset for the z axis be positive not negative?

Hi Daniel, I have an anet a8 with an inductive probe. It is to the left and in front of the nozzle, x= -27, y= -40 I have it all set up and configured in marlin, but when it tries to perform the autolevel, the probe not above the bed, it is to the left and in front. Any ideas? By the way, you and your videos have been brilliant in helping get everything set up on my 3d printer that i got just before christmas, many thanks.

What is the wiring setup for the connectors to the main board? You did not seem to show it in the video.

Great video! Does this work the same on the A8 PLUS? :) Thanks!

after doing all the upgrades (firmware, your config.h file, I bought an inductive sensor, I did my own pcb to use an universal/safe way for your NPN-Sensor circuit, etc) for a leveling sensor everything works great but for some reason when printing the left side has less pressure (extruder head is far from bed), than the right side. since the sensor and the firmware are in control, I don't know what to do to adjust this. Any comments and/or advice. Thanks in advance.

Hi sir can i use this same setup for NPN inductive sensor

Also, before you flashed Marlin and did the calibration, how did you determine how high above the nozzle tip to mount the sensor?

Great video, would the config.h file work the same with an anet a6?

Hey do you have a List of the changes you have made in your config.h?

Very timely video for me :) Thanks! I was wondering if you fitted a voltage divider on the signal output of the sensor (assuming you're powering it with 12 V)? I'm finding conflicting details online but it feels like there wouldn't be a voltage problem since it's NPN, open collector.

hello daniel one question you got the sensor on 5volts or to 12 because in 5 bolt it reads t low on glass 1...2 mm in 12 volts it want a 1n4148 protection diode on black cable(signal) inverted to not damage the main board....

Hello, Im having trouble with the Z offset, no matter which value I put the nozzle stand at the same height, but in the LCD show the value i put. Anyone has the solution for this?

Hi Daniel After flashing the firmware, My nozzle isnt leeling at the centre of the the bed... where do I change that in my Configuration.h file, and also what do I change in it ? im using the standard 220x200 bed which shipped with the printer

hey! your videos are veeery good! i learn a lot with you! but i have too much trouble to level my anet a8.

I don't have the "prepare" option in the marlin menu. I'm running Marlin 2.0.7.2. Have there been significant changes in the firmware since this video came online ?

Are you measuring from the center of the sensor or from the edge nearest the nozzle. I am trying to set up an LGDehome sensor.

I keep getting liquidcrystal.h errors whilst trying to compile. Any clues?

thank you...

Hallo there. I have a problem while compiling... I already installed the lcd display and the newest firmware marlin. But when I try to use the bed level sensor firmware to compile with the LCD enabled it says "exit status 1" unable to compile. Only when i leave the LCD out of the compiling everything works ok. How can i use my lcd and the sensor at the same time? Do I need to switch to the old lcd back again?

trying to get the same model bed level sensor working on my A8 but haveing compiling errors

hi, danke erstmal für das Super Video =) Sensor wird erkannt, beim Homing ist es so - sobald der Sensor ein Signal sendet fährt er zurück und dann sagt der Drucker "Homing failed" und dann geht nichts mehr. Hast du einen Tipp für mich woran das liegen kann? Grüße

where does this plug in to the board at?

what is the version of marlin you use in this video? please it is urgent. Thanks in advance.

Hey just followed this guide (thanks). Only issue I am having is that the sensor doesn't appear to be sensitive enough.

Hi uncle can u pls make a vedio for how to install auto leveling sensor on anet et4 printer pls

hey does it work with a magnetic build plate

Can you add link to the mount shown in video

I do not have that Probe Z offset selection ability. How did you add this to yours? ive downloaded your configuration file, but always seem to get an error when compiling in arduino.

How far from the bed should the sensor be or should it be level with the tip of the nozzle ?

Firt of all, ''bravo'' for all your videos ! I like your channel a lot ! Does anyone know if the wiring is different on the 1.7 version of the Anet A8 motherboard's ?

Does this work for A8 plus?

what kind for ruler is that?

I got everything loaded and it went fine. I went to start my first print, it did the up and down 3 point calibration (middle, left, right). After that it moved farther to the right and went down far crashing into the bed and pushing it down quite a ways, it does this movement once then starts printing after it, any idea why it is doing this? I have tried restarting the print and it does the same thing. Thanks for the video, it made it easy!

I cannot find a link to the pre-setup sensors for the Anet A8 in the Uk, does anyone know of any?

Hello, my sensor bracket it's different, so my values are X=-24 and Y=-44. when I compile the file it shows the error "RIGH PROBE BED POSITION it's outside of the probe region, do you know how to fix it? thank you

Please help, how do you wire the capacitive sensor? My sensor keeps blinking and does not work, the nozzle rammed into the bed. I'm not sure which wire goes in what slot on the jst connector.

I have an issue with the auto home. The print head will home X then move to center of build plate and home Z, but it won't home the Y axis. If the build place is set too far forward then the Y motor will push the bed until it stops then keep trying to move it. I have searched and search but can't locate why this happens or how to fix it. Any ideas?

when i try and change the configuration.h to enable any auto bed leveling vscode wont compile. but when i compile a stock marlin configure it is fine. anybody have any idea what is happening?

I installed Marlin 1.1.9 to my Anet A8 following your tutorial and using your configuration with only the x and y offset of the sensor modified, also burned Optiboot, but now when I select any option from the menu (example Prepare) it takes me back to the info screen... what can I do to fix this?

Hi Crosslink, why my Anet A8 with board v1.7 (she had a 1.5 but it was replaced because it die) when is heating up, no matter the temp thet you stablish for printing she never goes to the temp goal and stay always 5º behind and like this the printer doesn´t start... I have to feed directly the 12 V in the mosfet to heat up to the stablish temp.... can you help me?

hola amigo una consulta tengo un problema al ejecutar el G29 en la parte izquierda no para de bajar solo pasa cuando esta caliente la cama cuando esta en frio no pasa me podria ayudar con esto te lo agradeceria

I have an inductive sensor sn05 npn open collector do i power it from the 12 volt on the ps or do i have to supply it 5 volts and when i tried it with 5volts from the plug center when i home the head goes to the center goes up and stops it never comes down to the plate cant figure what is wrong please help

im having problem with homing because my prob is at x-36 and y-17 so when homing with probe it wont hit the bed, would like to home in center of bed hope someone can help me thanks

I followed all the steps from the video, even im using your configuration file, but when doing auto home, the extruder keeps going down on z axis, crashing with glass bed. The led on the sensor is not turning on when getting closer to bed. Im using a LJC18A3-H-Z/BY sensor. I have conected the wire of the sensor on the slot of the stock z sensor of the anet. Red wire is positive, black is in middle, and blue is ground.

how did you set the cap sensor??

@Crosslink3D When I run Autohome, the sensor or hotend is not in the centre of the heat bed. I'm sure the config is correct but can't work it out. Note I've used your config file.

Mi changes on the Z_PROBE_OFFSET do not work at all. How do you decide the height on the probe mount?

Followed your instructions and copied your config. When tested with auto home I can move the probe and z will stop but when I go to auto level the probe will not stop the z, it only works during auto home. Thank you for your help.

Why it is not working? I have done everything but the firemware is not uploads, it says: "static assertion failed: FRONT_PROBE_BED_POSITION is outside the probe region." What can Ido to fix it?

Is capacity sensor accurate? Because they are sensitive to temperature and humidity

I downloaded your configuration h file and When I compile the sketch I get..missing binary operator before token “(“ And it highlights..#if enabled (blinkm) || enable (rgb_led) || enabled (raw_led) || enabled (pca9632) || enabled (neopixel_led)

Does anyone know what wire to cut for the anet A8 plus

Hi I have this error and I have no idea how to fix it would appreciate some help, objectnotfound: (platformio:string) [], commandnotfoundexception And sometimes it says that the configuration h file is too old

I have the Marlin 1.1.9 and in control,motion i dont have the probe set

Hi does anyone have the : End of GCode sequence because i think Daniel forgot to add it in the description .

Question will this work on marlin 2.0

Question of the day: What is the most painful for you when it comes to bed leveling on a 3D printer. Please let me know in the comment section. Let's discuss!

I've downloaded your config.h but when i try to compile I get an error static assertion failed: FRONT_PROBE_BED_POSITION is outside the probe region.

Hi Guys, currently trying to get a configuration for my anet a8 with bed levelling but came up with this error when i complied the sketch. It said 'non constant condition for static assertion' with this line highlighted - > " static_assert(digitalPinToPCICR(Z_MIN_PIN) != NULL, "Z_MIN_PIN is not interrupt-capable"); " Any ideas??

if X,Y go home nozzle position out from area Bed ?

My Anet A8 was turned off suddenly after auto home (i have installed Marlin recently). Could it be an SD Card problem or is it a Marlin problem?

how do i know if my sensor is working i did the things you say in the videos but my printer wont stop moving when i put something under the sensor it just wants to ram the bed

Would this sensor work with the Anet E12 it has a 300x300mm bed

I have a problem filermant leecking back throu the threds how fize this

hey. you don't need a optokopplerplatine?

Which one is better, this one or the auto level sensor?

I managed to get the sensor working and the bed leveling works, but the moment it starts printing the nozzle is much to low and touching the print bed. Please help!!

pls can you send all this anet a8 upgrades 3d files. thank you ..

There's just one thing missing: Where does the sensor plug into the board. I was told by sources that I could mod a Alunar m508 with this method, however there is ports on the board that house 6-pins. Named icsp and icsp2, there is also a series of pins called a11, a12, d11, d12. Unless I was lied to, then I just wasted $18 on a sensor I don't need :P
