Older Ender 3 Warning: If you have an older Ender 3 with the 8-Bit control board you will also need to either install a bootloader (we have a kit here: TH3D Bootloader kit) or replace the control board with a newer one like our EZBoard or the V4.2.7 boards that come with bootloaders pre-installed.

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.

S (verified owner) –
Has made printing objects go alot smoother and faster though i recommend changing the following line in the gcode “G4 S10; wait for heaters to recover” to “G4 S20; wait for heaters to recover” as 10 seconds [S10} wasn’t near enough time for the hot end on my ender 3 pro to recover a few times and i had to stop the print during the wipe and manually do a preheat before restarting the print.
