Full background and details on the SFX-100 DIY project from the creator's official site:

Our DIY parts and kits are fully compatible with 90ST series servo motors and AASD-15A drivers; and can be used with the Arduino Leonardo (coding required) controller as per the original design for the SFX-100.

For the best experience and much greater expandability, we highly recommend to use the industrial standard Thanos AMC-AASD15A controller (plug-n-play!). It packs with many great features and allows you to expand your system upto 7 axis (6DOF)!!!

Choice of software includes the entry level motion control software that are freely downloadable (for private use only), or become the true EXPERT with other professional motion simulation software such as Sim Racing StudioSimTools, and FlyPT Mover. You make your own choice and no "sponsor" required!
