CLOSE ALL SLICERS BEFORE FLASHING
We support over 25 different printer models and all are listed on the Unified Firmware page.
•
Download the latest Unified Firmware Package for your machine from
and extract all the files to a folder on your computer.
o
Check Unified 2 section for your machine/board support and if it is not
supported in Unified 2 yet then go with the Unified 1 firmware.
•
Follow the directions at the top of the Configuration.h and on the firmware download
page for your machine.
o
Be sure to follow each step and make sure you enable a probe mount for the
mount you are using on your machine.
•
Set the EZABL_PROBE_EDGE setting to 45-50mm for larger printer beds (300mm+ size
beds) and 15-20mm for smaller printer beds.
o
Adjust the probe edge so that it is not probing over any bed clips or screws. This
will skew the reading.
•
We recommend using an EZABL_POINTS setting of 3 (this is the default) to start with
and most people use this value on beds up to 300x300. Larger beds should use 5.
If you have a printer that needs a bootloader this must be flashed before you can load any
firmware on the machine. Most printers with a 1284p CPU will need their bootloader flashed.
You can follow our bootloader flashing guide by visiting

Probe mount STL files are included in the Unified Firmware package for every
model and probe mount variation that we support.
Be sure to reset your printer EEPROM by either going to Control>Reset EEPROM or you can
reset it via Gcode by sending a M502 followed by a M500. This will wipe the EEPROM and put
the firmware defaults in. Failure to do this step will result in erratic printer behavior.
Adding the EZABL™ Pro Kit to a Custom Printer
Setup the firmware as if you did not have a probe and follow our Marlin setup guide here:
Custom Probe Mount Setup
If you have a probe mount you will need to measure the distance on X and Y that the center tip
of the probe is from the tip of the nozzle. Those will then be entered into the custom probe
section in the firmware. This is in the “
Custom Probe Mount Settings
” section and
there is a
visual layout in the firmware showing an example.
