The EZABL™ Pro 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 and supported by our US Tech Support team.
Our EZABL kit works with most 3D Printers. To make sure we have firmware and official support for your particular printer model check our official compatibility list here: EZABL Printer & Firmware Support List

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. All our STL files are located in the Unified 2 STL Pack. You will either need to print a mount for your particular printer or select one from our OEM mount selection above.
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.
Do I need to have a bootloader on my printer?
Yes, you do and most modern printers have this already loaded on the board. Almost all 32 Bit CPU boards come with bootloaders on them.
If your printer has a 1284p CPU on it, then you will need to flash the bootloader. Add on the Bootloader kit above.
If you are not sure you can use the Live Chat or Contact Us and we can let you know if your printer needs a bootloader flashed or not.
Does the EZABL work with Klipper?
Yes, these probes are supported by Klipper firmware. You can see our Klipper setup guide here: https://support.th3dstudio.com/helpcenter/ezabl-klipper-setup-guide/
Our support covers the EZABL probe setup. Before installing our probe you must make sure the rest of your Klipper setup is completed.
What is the accuracy of the EZABL™ Pro?
On a machine with no mechanical issues and a properly installed sensor our kits achieve 0.01mm or better accuracy. Most of our customers report a M48 result of 0.005-0.001mm when properly installed.
Can you include a sensor mount?
We have "OEM" mounts available above as optional addons but if you want a custom mount printed up we also offer print services in PLA, PETG, and ABS. Contact Us with the STL files if you want a custom mount printed.
How much does the EZABL™ Pro sensor weigh?
- 18mm is about 0.9oz w/2x Included Nuts
- 8mm is about 0.3oz w/2x Included Nuts
What is the maximum ambient temperature the EZABL™ can operate in?
The maximum ambient temperature recommended is up to 70C. We have tested them in enclosures up to 75C ambient temperatures.
Ambient is the temperature of the air around the sensor. You can use our EZABL on bed temperatures up to 150C.
Does the EZABL™ work on *insert surface here*?
Our sensors work on all print surfaces that you print on. Our sensors do not require a special type or color of surface to work. This means you can use them on glass, pei, steel, flexplates, garolite, and more!
What is the difference between the EZABL™ Pro/Mini/Micro?
Just the physical size and weight of the sensor. We have smaller sensors for people who want a smaller, lighter probe for specialized applications where the larger 18mm probe will not fit.
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 build our custom EZABL™ Pro boards & sensors. All final testing, QC, packaging, and support is done here in the US.
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, Klipper, or RepRap based machine. However, our included support covers machines that are listed above with their original control boards (or supported aftermarket boards) and our Unified Firmware. 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.
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!

Myles W. (verified owner) –
Bed levelling is one of the biggest hassles of most 3D printers. I stopped 3D printing for almost a year because I was constantly getting frustrated with bed levelling issues. Now i’m back to printing everyday and I know I can just turn on the printer, fire up a print, and have consistent results every time.
Just a warning though, ABL can only compensate for so much, you have to make sure your bed is trammed reasonably well (making sure it’s as parallel as possible with the X gantry). But once you do that, you never have to touch the bed knobs ever again.
I have taken off one star because the OEM Ender 3 mount option is poorly designed, and poorly printed on top of that.
– The adapter rings to fit the 12mm sensor have elephant’s foot and therefore would not fit over the sensor’s plastic threads without damaging them
– It blocks the bolt for one of the carriage wheels
– Too thick around the screw holes, preventing the screws from threading into the carriage plate. Had to ream them with a drill bit.
– Unnecessary overhangs
– Very rough, inconsistent surface finish
The mount will get you by, but if you already have a working printer it’s much preferable to print a mount from Thingiverse. I ended up designing and printing my own mount which is much more suitable for the Mini.

This thing makes printing small precise models a breeze and their customer support is amazing and the instructions cover everything.
HOWEVER, some parts seem out of date, mainly the calibrating the sensor section because it doesn’t mention the green and red LEDs, also there is not a single video online explaining how to set up the current model not even from TH3D. Also “plug and print” isn’t accurate especially if your printer does not have a bootloader.
ALSO, BE EXTREMELY CAREFUL OFFSETTING ZERO, when I offsetted the zero the way shown in the video they provided via a link in the instructions it was so low it crashed into the side of the bed and when I pushed the bed down to move it out of the way the nozzle became buried into the bed leaving a small crater.
ALSO ALSO, the lid for the ezabl circuit board case is really hard to open when its shut so don’t close it until you are completely done
ALSO ALSO ALSO make sure you have the following because it isn’t in the base kit
mount (can be bought as an extra or printed)
Arduino uno with jumper wires and USB chord (can be bought as an extra)
hardware(can’t be bought as an extra, idk what type of screw it is but on an ender 3 the screw that fastens the back of the lid covering the motherboard fits)
