What is the EZABL?

The EZABL Kit is a fully original design (V1 released in Early 2017) that makes adding an Auto Bed Leveling Sensor to your printer much easier than DIY solutions. We are one of the few ABL kit makers that offer support from the hardware to the firmware.

We hand make each and every kit in the USA starting with a bare PCB. We then place, solder, test, and assemble every kit by hand.

We support over 20 different printers out of the box complete with firmware and sensor mounts. See the full list here: TH3D Unified Firmware

Works on ALL print surfaces, even beds that are 100% glass. We use high quality hardware (all custom made for us and by us) and spend countless hours making sure the firmware is tuned as perfect as possible. Our support is unmatched by even companies much larger than us.

Our in house team can handle any printer from an entry level printer to a fully custom machine.

With over 10,000 kits sold you will see why people choose TH3D for their printer upgrades and parts.

There are 4 versions available – a 12mm EZABL Mini and 18mm EZABL both come in “Direct Wire” and “EZConnect” versions.

The EZConnect is mainly for CR-10, CR-10S, CR-20, Ender 2, Ender3, Alfawise U10, or Tornado Users that want a quick installation where they don’t have to cut any wires or tap into the printer power. Just plug the kit into the wall outlet or USB Port with the USB adapter, connect the Z endstop, and load the firmware.

The Direct Wire kits are for all printer users that don’t mind running a power wire (included) to their power supply, cutting the Z endstop wire, and inserting it into the screw terminals on the module. This will also work on any of the other machines listed above.

Frequently Asked Questions

  • What is the difference between the EZConnect and Direct wire?
    • The only differences are how the Power and Z Endstop wires connect. They are the same kit otherwise.
    • Direct wire has 2 screw terminals for the power and Z endstop connection.
      • This works with all machines we support. If you have a 2/3 pin plug on your Z it will be cut off during installation and the wires connect to our Direct wire board (see the install video).
    • EZ-Connect has a DC Power jack for power and a 3 pin JST plug for the Z endstop connection.
      • This is for the machines listed on the EZ-Connect product page that come with a 2/3 Pin JST plug on the Z endstop switch.
  • What is the difference between the EZABL (18mm) and the EZABL Mini (12mm)?
    • Both are very accurate (under 0.01mm) on machines with no issues.
    • The EZABL Mini is physically smaller than the EZABL.
    • The EZABL Mini weighs 50% less than the EZABL
  • Do you offer installation on a printer?
    • If we have time yes. Please contact us for a quote and availability.
  • Is the EZABL kit gluten free?
    • Yes. The EZABL kits are 100% Gluten Free.
