Product Info

What is the EZABL™?

The EZABL™ kit is a product designed, manufactured, and sold exclusively by TH3D to make adding automatic bed leveling (ABL) to your printer as easy as possible.

Everything from the hardware and firmware to use the kit is tuned for the best performance by us here at TH3D. Technical support is included at no charge through our TH3D Helpdesk Email system.

We use the highest quality parts in our sensors, on our boards, and even the cabling. This means you get an ABL kit that is not only easy to install and use but one that will perform. Don’t be fooled by cheaper kits that use cheap parts to cut cost.

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 everyone’s 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.

  • 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. If you are still not sure you can use the Live Chat or Contact Us and we can let you know.

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 variation 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 do not 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 or use our Live Chat with any questions you may have and we’ll be happy to answer them!

    Not so EZ

    Frank Wildenberg (verified owner)

    Be careful before you buy this product. For it to work properly your machine has to be perfectly aligned. All the axes have to be checked, so start brushing up on how eccentric nuts work. Also you have to make sure your bed is aligned, be prepared to put extra rings under the blocks you can order here because you’ll probably need it. If you aren’t that familiar with your printer, expect a lot of reading from the guides here and hope you can understand it all. Support will reference to it a lot, expect little personalized help.

    This is all my personal experience with the product and Tech support. Installment was doable, getting it all to work cost me a lot more effort than I think it was worth.
