How To Get Your Software License

Thank you for your interest in our software. Registering your device is very easy, and each zCube device extension corresponds to your hardware device (see the list of supported devices below) and contains an auto-registration process.

zCube (z3) Extensions (2025-04):

SLI-PRO: z3slipro and z3slipro_lite

SLI-F1: z3slif1 and z3slif1_lite

SLI-M: z3slim and z3slim_lite

SLI-FTEC (Fanatec Conversion Kit): z3sliftec and z3sliftec_lite

SCN5 and SCN6 (Dyadic System Electric Linear Actuator): z3scn

License Registration Process

The first time the extension is loaded, it will automatically detect if the license is valid. If no license is found, the system will prompt you to register.

A donation per device (in USD only) to our non-profit foundation is required to contribute to our projects and receive your software license.

Versions of the Software

All Leo Bodnar modules come in two versions:

Lite Version: Free for non-commercial use with limited features.
Full Version: Unlocks all features and is available with a donation.

The Lite version is completely free for personal, educational, or non-commercial use but comes with certain limitations compared to the Full version. To enjoy the complete functionality, we recommend upgrading to the Full version through a donation.

The z3scn module requires a registration.

A professional version (z3scnpro) is available on demand. The pro version offering additional advanced features and is dedicated to custom software development, contact us.

To register connect your device:

make sure it’s recognized by Windows (check the Devices and Printers control panel),
Download and install the z3 module corresponding to your hardware and install it using pip install <modulename> (see the releases for more info)
Create and run a python script to register (donation and creation of your developer account). See the documentation to create your python script.

# minimal script to register
# Load device extension and create the instance
# replace z3slipro by your device extension

import z3slipro as sli
device = sli.z3engine()

# Initialize device
if device.init():

    # Your script here

    # End of script
    device.terminate()

# minimal script to register the z3scn module
# the actuator must be configured with a COM Port (FTDI driver installed),
# recognized by Windows

import z3scn as scn

# init device with its COM port (here it is the COM port 4)
if scn.init(4):

    # Your script here

    # End of script
    scn.terminate()

else:
    print("Error: Initialization Failed!"
