Product Details

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 you can contact us and we can let you know. Some we will do for free (like the smaller OEM Mounts) others do have a charge.

  • 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

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.
