Product Info

The EZABL Kit is a fully original design that makes adding an Auto Bed Leveling Sensor to your printer much easier than DIY solutions with full support included should you need it.

***This version has it’s own power adapter. If you want to use the existing 12V or 24V from your printer PSU then check out the Direct Version here***

Shipping Time Note: All EZABL Orders ship in 1-3 days as we hand make them here in the US.

You will receive a full kit that includes:

  • TH3D EZABL Mini V3.1 Sensor pre-wired to our EZABL V3 Board and Power Adapter (AC or USB)
    • USB Power Adapter puts out 12V so sensor is as accurate with them as they are with the AC adapter.
    • Now includes the EZ-Direct Adapter tip should you want to wire power from the printer later on instead of the included power adapter.
  • Works on Glass, Mirror, Aluminum, Buildtak, Acrylic, and more
    • If you have an AC bed please see notes below about using it with the EZABL
  • Full Installation Documentation Included in the EZABL Customer Package
  • Pre-setup Firmware Included FREE to get you going quick
    • Sensor mount NOT included as we support many models. We include a STL pack with all the mounts.
    • If you need a mount printed leave a note on your order at checkout then contact us and we can let you know. Some we will do for free (like the smaller OEM Mounts) others do have a charge.
  • Support over Email is included with the kit through our TH3D Help Desk
  • 100% Original Kit Developed, Designed, and Assembled in the USA by TH3D (We build every kit by hand)
  • Tech Specs:
    • High Quality AC Adapter for smooth voltage output
      • USB Adapter needs a clean power source – Do not use with low end USB phone adapters
    • Onboard Power Filtering & Decoupling
    • High Speed Toshiba Optocoupler IC
    • Reverse Voltage Protection
    • High quality copper, 2 Layer PCB w/ Full Ground Plane
    • TH3D V3.1 100hz 12mm Capacitive Sensor – ONLY available from TH3D
      • Weighs only 20 grams, 1/2 the weight our regular EZABL sensor
      • New V3.1 sensors now come with shielded cables for EMI reduction and increased durability
    • Includes 12mm to 18mm Adapter to use with existing EZABL mounts
  • Works with ANY printer that runs Marlin but this kit is geared for the below machines that have a 2/3 pin JST Z endstop.
  • Some printers require a bootloader that needs an Uno to be flashed. Please check the Unified Firmware page to see if yours needs one (CR-10, Wanhao i3, Ender 2, Ender 3)

Support/Warranty

  • Included Support: TH3D Standard Support
    • Support is on the product itself. Your computer must see the printer COM port to update the firmware. PC issues are the customers responsibility to resolve.
  • Warranty: 90 Days
    • Physical or Electrical Damage due to improper installation or use is not covered. Items are all pre-tested before leaving the shop.

Extensive firmware setup assistance – phone, messenger, or video chat – is available but there may be a charge for this due to the involvement required or what the issue is. This does not apply if you are using a pre-supported printer listed above. Meaning if you want to add EZABL and aren’t familiar with your board/printer firmware we can assist you with this.

AC Bed Notes:

If you have an AC bed the frequency of the AC current can throw off the accuracy of the sensor. This can be avoided by simply turning off the AC bed when Z homes and G29 runs. Once those are completed you can turn the bed back on. If you use a SSR to control the AC bed (like what the Tevo Tornado has from the factory) the firmware will automatically manage this for you. If you are doing your own DIY SSR+AC Bed setup we highly recommend the MSSSR20 SSR from Misumi as it has very low AC leakage current. Some low quality SSRs will leak a small amount of AC current and can affect the sensor even when in the off state. There is a guide on our knowledgebase about using a wifi outlet + raspberry pi to manage a standalone heater.

Tevo Tornado Notes:

Some Tevo Tornado printers shipped with very low quality power supplies that have an open or poor ground and/or Solid State Relays that leak AC current. This can cause the kit to not work. Unless you have a high end multimeter or scope to check the grounding and ripping on the machine there is no way to tell if yours is affected. A new PSU and SSR is between $30-50 and we sell both of these for just a hair over cost to make replacements easy. If you end up not wanting to swap the PSU and SSR and you have a Tornado we will waive the restocking fee if you choose to return it. This affects our sensors, other similar types, and even BL Touch sensors (clones included).

  1. Chad Docken

    My original EZABL had some issues about a month into ownership. After contacting support we went through some basic troubleshooting before they decided to replace the unit entirely. The entire process was very quick and my new EZABL was up and running within a few days.
    The device itself is wonderful and I don’t need to worry about bed leveling anymore. Installation was also a breeze, just follow the instructions and you’ll be set. I definitely recommend this for both the product, and customer service.

  2. David Obregon

    Easy to install with the thorough instructions and troubleshooting steps if any issues arise. Makes it easy to perfectly adjust my first layer height. Good squish for PLA, higher off the surface for PETG, and the hot end is at the right distance across the whole surface without endless fighting with the bed level adjustments.

  3. Steven_sexton

    Install was straightforward, setup took a few tries of reading and watching videos and asking and reading comments on Facebook support site. But very well worthwhile. Prints are coming out much cleaner less surface errors. A very nice piece of hardware to add on to any 3D printer.

    Here’s the rub. The EZABL is amazing – there’s no doubt about that. And when I say amazing, I’m talking about life changing. Yeah, that’s right – life changing.

    However, there are a couple caveats… At least as it relates to the Ender 3/CR10.

    First, the mini has to sit very close to the bed. ~2mm to be exact. It’s not a problem, but for me it still makes me a bit uncomfortable (but I’m weird like that).

    Second, the stock mount for the Ender 3/CR10 is not great (not sure about others). The stock mount is only designed for the full size sensor – not the mini. They will send you some printed washers to use as adapters, but they’re not great. I threw mine in the trash after two days. You’ll want to either print your own washers with a better (more snug) fit or a whole new mount. If you don’t, it will be very easy to knock your sensor out of alignment.

    That’s it. The sensor rocks and TH3D rocks!

      Thanks for the feedback. If you have a better STL for the sensor rings please feel free to email it to us at Support@TH3DStudio.com.
