The EZABL™ Difference

There are many options to add auto bed leveling to your printer. Many of them are difficult to install, use, and/or just use poor quality parts. Our US based support team handles over 10,000 support tickets a year and are trained on all our products.

We aim to set ourselves apart from the competition in many ways and refuse to cut corners when it comes to support or the hardware.

We believe that the 3D Printing Community is a key part of everyones success. We are the only ABL kit maker that contributes to the Marlin Firmware project through monthly donations to help fund the project. Our EZABL™ Kits would not be possible without this firmware to build our Unified Firmware on so we feel it is only right to help out the project through direct financial contributions.

The EZABL™ Pro is the next level when it comes to quality and features.

  • ᵇ – Printers with this after the name needs a bootloader installed. We have a full flashing package here: TH3D Uno Bootloader Flashing Kit and a guide here: TH3D Bootloader Guide (Video)
  • ^^ – The Wanhao D6 has a compact head. The EZABL Mini does not reduce any print space using the mount supplied. You can use the regular EZABL however we do not have any pre-supported sensor mounts for it. The physical hardware works with the D6 board but we do not have a mounting option supplied for it. TLDR; Go with the EZABL Mini (12mm) if you have a Wanhao D6.
  • ᴸ – Printers with this after the name need a LCD conversion to work with our firmware and supported products.
  • Custom Mount – This means the firmware is set up and ready for the EZABL kit but you will need to locate a probe mount for that particular machine. We may add official mounts in the future but if this note is here you will need to supply your own probe mounting solution. If you have a mount that works with these machines on the stock hotend please email Support@TH3DStudio.com and we’ll get it officially added into the firmware and download package.
  • Our support on the EZABL covers the printers in the list above with their original control boards.
  • Setting up EZABL on Vanilla Marlin?. The EZABL works like a normally open endstop switch and will physically work with boards running Marlin or RepRap (Duet) but the included support does not cover getting your custom machine setup but support on a custom machine is available at an hourly rate. Otherwise you can always check out our communities for getting the EZABL working on a non-supported board/printer here: Community.TH3DStudio.com

Quality of our products is extremely important to us. Because of this our kits are more expensive than our competition due to the higher cost of the parts, materials, and support that go into making each kit. We’re a real company with actual staff, not someone selling on EBay or Amazon. As the old saying goes “you get what you pay for”.


How Does the EZABL™ Mount?

The EZABL™ mounts to your printer hotend and we supply STL files for over 40+ different mounting options for the 25+ machines we support. There is a folder in our Unified Firmware Package that contains all the mounts that we have supported in the firmware so you can get setup without having to measure sensor offsets. You may need some M3 screws (or others depending on the mount) to mount the sensor and we have a screw assortment that covers all the sizes you may need for all the most popular mounts.

Can you include a sensor mount?

Absolutely! If it’s one of the “OEM” style ones listed above you can select it in ABS or PLA material. Supports are removed from the prints before shipping. If you want us to print a custom mount (like a herome or petsfang) you can Contact Us with the STL files for a printed part quote, we do prints in ABS and PLA.

Will I have to Solder?

Nope. Not at all.

Does the EZABL work on *insert surface here*?

The answer is yes to any printing surfaces. This includes glass, mirror, polyprop sheets, acrylic, aluminum, ezmat, pei, buildtak, and any other surface you print on. Unlike other solutions, the EZABL™ works on all print surfaces without requiring modification to the surface.

What is the difference between the EZABL™ Pro and the EZABL™ Pro Mini?

Only the physical size and the Mini weighs a few grams less. Some printers cannot fit a standard size probe so we came out with the Mini to fit those machines (example: Wanhao D6).

Do I need to have a bootloader on my printer?

Yes. You will need to update your printer with our awesome firmware package and that requires a bootloader. If you are not sure if your machine has a bootloader then check the Unified Firmware page and there is a chart on there that shows what machines need it.

Do I need to change my printer board to use the EZABL™ Pro?

Nope! We’ve spend hundreds of hours making firmware for all the machines we support and enabling tons of new features and safety improvements for your stock printer board. Check the Unified Firmware page to see what machines we support.

Will the EZABL™ Pro work with an AC Bed?

Yes! We’ve made major improvements to the new Pro sensors that make them work on AC beds that are properly connected with a quality SSR. If you use a good SSR (like the Mager we sell) then you will have no issues with your EZABL™ kit with an AC bed (and you can control the bed from your printer!)

Where is the EZABL™ Pro made?

The EZABL™ Pro is designed by TH3D and we use multiple suppliers across the globe to source the parts and assemble our custom EZABL™ Pro boards & sensors. All final testing, QC, packaging, and support is done here in the US.

Why is the EZABL™ Pro “so expensive”?

Because quality parts and excellent support people are not cheap. We don’t focus on the race to the bottom like other companies. Quality and excellent customer service is the focus here at TH3D. If you want a cheaper kit check out eBay.

I have a custom printer or one with a control board I swapped, will you setup my firmware for me?

The EZABL will work with any Marlin or RepRap based machine. However, our included support covers machines that are listed above with their original control boards. On custom printers (this includes models we support but with their boards swapped) we cannot possibly account for every varation when a customer swaps their board or has a custom machine. We do have hourly support available here should you need custom work: https://www.th3dstudio.com/product/3d-printer-support/

We also have our communities to get help as well that doesn’t cost anything to use: http://Community.TH3DStudio.com

What about the “Direct Wire” or “EZ-Connect” Kits that were available previously?

We’ve simplified the product and made it very compatible by having both connection types on the new EZABL™ Pro Control Board. 1 Board to rule them all.

Do I have to make my own wiring harness or modify my board to use the EZABL™ Pro kit?

Nope! We supply all the wiring and a 1.5M sensor cable length with a modular connection. Unlike competitors that require you to modify your printer board or make your own wiring harness to use their sensors we supply everything to connect it and require no modification to your printer board.

Does the EZABL™ Pro Kit work with OctoPrint/EZPi?

Absolutely! We love OctoPrint and use it here. Every one of our production machines has an EZPi kit on it and our EZABL™ kit.

Have a question we didn’t cover here?

No problem! Contact our Support Team with any questions you may have and we’ll be happy to answer them!

    The Best add on i have done to my CR-10...

    m.cornieles (verified owner)

    I try to be as honest as i can on reviews because when i make any purchase i rely on other people reviews….
    So far this is the best piece of hardware and software I have added to my CR-10 printer.. is a shame i wait almost 18 month to do so.
    This product simply works PERIOD. Since i installed the EZABL pro kit to my printer i have had only 2 bad prints and none were relate to the printer, it was the filament that broke due to a bad extruder….

    I once said, all 3D printers should come by default with this EZable installed, that would change the experience of 3D printing… i had to go through a tone of issues because of not labeled bed but that is on the past…

    5 out of 5 starts for this product…. NICE work TH3D.

  2. Best upgrade yet for my Ender 5. Just buy it.

    iain.wheeley (verified owner)

    I can’t believe I waited so long to bite the bullet on this purchase. Easy to install and calibrate and I have now pretty much given up on baby-sitting my first layers on any print I do for PLA, PLA+ and PETG as I know it will come out perfect.

    The world is flat downunder now.

    reconit (verified owner)

    Ordered from Australia, arrived quick but more importantly it is running fantastic. It is by far the single biggest hurdle to 3D printing (getting a bed level) and it is now fully automated on my machine. Took about half a day in time to get it all operating to the level I am now very happy to achieved with the EZABL. Well done TH3D you have developed a great product, let me know if you ever decide to IPO.

    All the issues I had installing this were my fault. Period, end of discussion.

    The biggest thing to remember is that when you’re adjusting the sensitivity, you’re setting the point at which you want to stop to keep from crashing into the bed. So when they say you want the light on, you want the RED light on, and only just on. When I first installed it and calibrated I set the red light to be just barely off. That was a poor decision, leading to inconsistent leveling and driving my hotend into the bed many times before I sucked it up and redid everything.

    Now though? I’ve gone from fiddling with everything multiple times in the first frantic minute of a print to (with solid bed mounts) twiddling the nob once or twice to babystep and then walking away. Much easier, more consistent, and less stress and fretting. My one problem is the starting gcode provided puts the swipes on the very edge of the build plate–however since I’m using a mirror bed from Ikea, I have to put the mirror on the very far left in order to avoid printing into thin air. Not a problem by a long shot, just means I’m watching for those magnetic build sheet sets to come back in stock ASAP!

  5. Terrific Easy Upgrade on the Ender 3

    hrsnround34 (verified owner)

    Very Easy hardwire install on my Ender 3.

    I watched the videos a couple times in the last week before ordering. Once i got the EZABL it was such an simple install.

    I only did this upgrade so i could switch between surfaces without having to re-level the bed.

    I probe 9 spots on the bed and the variation from spot to spot is 4.5 to 4.7. so the bed is definatly not warped.

    You must follow the Z calibration instructions. Watch the video. Do not pinch the paper under the nozzle like you do on manual level. Just let it grab the paper. I had my nozzle so tight to the bed that the fillament was jamming and backing up in the tube. After cleaning the 4th jam. I re-watched the video and saw how Tim just let it grab the paper and then backed it off using the baby stepping. I then did the same and i have had perfect prints every time.

    I have tested going from a magnetic surface, to a TH3D EZMat on a hard plate to a glass surface. Now i just change surfaces, tell it to print and let it run. No readjust needed.

  6. EZABL Pro Well worth the money!

    carlos varas (verified owner)

    I had been using a generic sensor with an optocoupler for a while and could never get the level quiet right on my cr10 with mirrored glass. I tried everything and nothing worked until this sensor. I have to say that quality really does matter. While my previous sensor technically worked this one is sooo much better. I have a pretty warped bed and this thing just printed the best first layer covering most of the bed Ive ever seen!

  7. Can't believe its so good


    After 3 months of pulling my hair out. It was very frustrating only getting 1 print out of my CR10-S Pro then spending 2 days of frustration trying to re-level the bed because the stock sensor was rubbish.. I saw the EZABL pro and of course thought Naah it wont fix the issue..
    I was hesitating if I should spend anymore money on the printer.. I was ready to cut my losses.. But decided to give it a try..

    Well all I can say is WOW.. what a difference this thing makes.. I just send the gcode now to the printer and walk away..
    The EZABL combined with the solid Bed mounts and your bed leveling issues are a thing of the past.. I cant recommend the EZABL enough now..

  8. Simply the best

    justin.toner (verified owner)

    So now I can finally press the print button and confidently walk away knowing I will have a perfect print! I have upgraded two ender 3s, a cr10s pro and am getting ready to do my ender 5 plus as well. The reason, well since I put this abl on my ender3 it has been the most reliable printer of the bunch. I removed my skr mini and touch screen from my other ender3 pro with bl touch due to inconsistent prints and lots of issues. Swapped back to a 1.1.5 silent board and put the ezabl on with th3d firmware and now it too prints perfectly every time. Cr10s pro has been a nightmare trying to get consistent first layers. Hoping the ezabl kit I have for it but yet to install will make it print as well as my enders 3s. The cr10s pro and ender 5 plus won’t pause for me in cura post processing to make the printer pause at an exact layer to be able to change colors. Only the ender 3s with th3d firmware have worked for me when trying to do this so that and the perfect first layers are why all 4 of my creality printers will be ezabl outfitted.

  9. Great BLTouch replacement on my CR-20 Pro

    Ken (verified owner)

    This sensor works great on my Cr-20 Pro. It can probe the bed much faster than the BLTouch V3.0 the printer came with, all while staying extremely accurate even after it heats up. The EZABL is really easy to install and it is extremely straightforward to calibrate. The installation guide was easy to follow and documented each step perfectly. The build quality of this sensor is miles above the BLTouch and has no moving parts to break.

  10. Great Upgrade and 10 Star Support ... My Ender 3 Pro is now truly a "Pro" printer

    pumbaa17 (verified owner)

    The EZABL Pro was a Christmas present to myself and at first I was not sure I was happy with it. It was a journey and in the end all of the issues were mine. That said I now have an Ender 3 Pro that is fine tuned to consistently deliver a great first layer and great quality prints overall.

    The setup guide was easy to follow and detailed. I had the unit installed and configured in no time at all but initially my print quality did not change a bit. I contacted support and began my journey with Mac began. He was quick to react, provided detailed guidance and suggestions and when available include links or photos to help explain the actions he was asking me to take. We were pen pals for almost a month. This had everything to do with me and my schedule and nothing to do with TH3D/Mac. I almost always had an e-mail response within 24 hours.

    In the end,all of the issue we mine and easily resolved. I now have a supremely aligned printer frame, fully grounded and calibrated sensor. Very happy with my purchase and my introduction to TH3D.

    Tim – I cannot say enough about the support that Mac provided. Timely, professional, patient with a relatively new user and always there with a suggestion, advice or guidance. If all of your team provides the same level of customer service your company has a great future. Thanks for the great products and service.

  12. I love it, Ender 3 Pro here.

    Cornelius H (verified owner)

    I thought I’d order it and wait for a good day to dedicate to configuring a new setup, but overall this was far easier to setup than the Ender 3 pro and/or using an Arduino to flash the Ender firmware to Marlin ( which I was running before I bought this). A pdf scan and youtube video later and this thing is printing better than I could have imagined. On top of that, I went for the solid bed mounts which makes this all even easier.

    Definitely happy with this purchase. It’s going to save me hours on printer troubleshooting and setup.

    Life Changing Upgrade

    Rolo (verified owner)

    I was so sick of manual bed leveling using springs and adjustment knobs. I was never able to get it right and would get so frustrated I’d give up on most print jobs. I was ready to throw out the printer. I’d been considering the EZABL for sometime, but was intimidated by the install, and it turned out to be a lot easier than expected. This paired great with the Solid Bed Mounts! This was a life changing upgrade and I’ve never printed so well. I recommended it to a friend who was also having issues and it’s changed his life too. Highly recommended. My prints never printed as good as they do now. It definitely brings peace of mind.

    EZABL my first big modification for my Ender 3

    tbabcock67 (verified owner)

    This was my first purchase from TH3D and cant say enough about how well this works and the over all benefit it made to the quality of my prints. I am fairly new to 3D printing and will admit the physical install of the device is quite easy but getting all of the computer work done left me with multiple challenges. I would highly recommend doing all the research first before preparing to take on this task. Understand how to flash and set up the Unified firmware as well as the settings in your start gcode of your slicer. When complete, it performs just as advertised and even better then I expected. The support team is amazing and adds so much value to the purchase of the product it will be easy for me to buy more items from Tim and the TH3D group in the near future.

    Sure you can level your bed, but if the surface isn’t flat then what? Then you get the EZABL, now perfect first layers every time. Turned my CR-10S from a headache into a rock solid machine.

    So much easier

    Antony Pearce (verified owner)

    I have been printing for over two years with a couple of different printers. I installed an EZABL on my CR-10S on Tuesday night. Tonight is the first time I have ever walked away before the printer had finished the first layer, in fact it hadn’t even completed all the outlines.

    Strate out of the box I had issues with my CR10S hot bed being warped. After months of issues and countless YouTube videos on fixes using tape etc. I stumbled upon th3d and their EZabl kits. I was sold immediately as I was desperate for a solution. So glad I did. With their firmware and ezable I now have peace of mind that my printer is not only safer to use but also I am no longer wasting filament and getting amazing prints every time.

    Thank you Tim and team for the awesome firmware and products.

    Stop thinking about it, and DO IT!

    I’m fairly new to 3D printing, but I like to get my hands on technology as much as possible. I bought an Ender 3 Pro, without knowing ANYTHING about 3D printing. I ended up with a crash course on how things work, different terminologies, and was at it for about 2 weeks before I was tired of leveling my bed. I didn’t want to take a chance on an eBay kit, so I came to TH3D and started reading through different things, and decided this was the best kit for me. I ordered everything including the solid bed mounts and Arduino Uno. I will admit some of the instructional videos are fast-paced, but after watching, pausing, watching again- I got it tackled. My printer has been NONSTOP since, and the quality of what I’m printing has improved SO much.
    I can’t speak for other printers, but if you have a Creality printer (Ender 2/3/Pro, CR, etc) then definitely get this!

    Make sure you have some extra screws for mounting the sensor to the hotend, I lucked out and reused some from my extruder before I upgraded.

    Oh, the Nerds were a nice touch.

  22. Smooth Installation, works perfectly

    Barry Mizes (verified owner)

    I had manually leveled my bed and been using it that way for a number of months. The problem was that the glass was warped to varying degrees and so while I could get a few areas level, other areas would not be level. As long as I printed in these distinct leveled areas, everything was good. Last week I decided to print something large, and of course, those parts in the unlevelable areas did not adhere properly. Being tired of this nonsense, I bought the EZABL Pro kit and installed it this morning. Using the printed guide and the video, the installation was easy (I had already uploaded a bootloader and new firmware). To really test how well it worked, my first print was a large item that I set to print dead center where the worst warp had been. I’m happy to report that the first layer printed perfectly – everything adhered and no curls or missing areas. I know there are lots of options out there for bed leveling, but what sets Tim’s gear apart is that he has made it easy for anyone to install and use it. It just plain works. Thanks again for a well designed and supported product.

    Best ABL kit on the market!

    mmathosian (verified owner)

    Easy to set up. Incredibly accurate and consistent results. This is my second EZABL kit from TH3D and I wouldn’t use anything else!

  24. So far so good

    jeff.buzzell (verified owner)

    The install was easier than i expected. followed the instructions and bam, it worked. Great upgrade though makes me realize how warped my bed is.

    The things i would change are some better cable management for the control box and a better connector for the power in the control box. the small wires and location are difficult to connect up.

  26. Bed leveling is a thing of the past

    TreeClocker67 (verified owner)

    Do you spend your precious time leveling your bed manually like some kind of 3D printing cave man? Do you want to have beautiful first layers? Do you want the ability to hit print and not have to worry about watching your first layer to see if your manual leveling job turned your nozzle into a bed engraving tool?

    Then buy the EZABL Pro and throw that paper away. Rejoice knowing that after you install the EZABL Pro you’ll be saving trees from being used as a leveling too.

    The installation of the EZABL pro is way easier than the old version, the included case has more mounting options, the option to directly power it via a plug OR direct wire, no more plug cutting, the color scheme.

    The EZABL Pro/EZABL are on both my printers and make printing life so much better.

    After struggling for more than 40 hours with two different BLTouch V3.1 on an Ender 3 and finally determining that despite all the guides and all the firmware changes, it just wasn’t going to work. I received the EZABL sooner than the tracking said and it was installed in under an hour. It works exactly as advertised. The guide and video were extremely thorough and the kit is well designed. The Unified firmware was packaged well which made it simple to configure and compile. I wish I had started with EZABL and not BLtouch but lesson learned.

  28. Goodbye BLTouch, hello EZABL!

    Spencer Francisco (verified owner)

    I’ve been a BLTouch evangelist for awhile until I did my own independent repeatable tests to find that it wasn’t as consistent as I hoped. This was after doing all kinds of bed adjustments from different springs to removal of springs. Still couldn’t get the best first layer. After doing some homework on the EZABL, I couldn’t believe I didn’t have this sooner. The install was pretty straight forward and the Unified Firmware had some simple configuration to get started. So far I’m very happy with the results. Thanks guys!
