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 Direct Wire if you have a Wanhao D6.
  • 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 and materials that go into making each kit. As the old saying goes “you get what you pay for”.

    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.

  3. 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.

  5. Awesome product

    skater-boy24ryan (verified owner)

    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.

    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.

    Stop thinking about it, and DO IT!

    patrickjhenninger (verified owner)

    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.

    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.

    It like getting a new printer.

    spudmlgnjr (verified owner)

    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.

    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.

  14. 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.

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 that are smaller we can include those free of charge by selecting above for the ones supported. Free mounts are done in 100% US made Black 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!
