Sigmoid Series – 3D Printer Control Units

Sigmoid Series – 3D Printer Control Units

Say hello to the world´s first 3D-Printer Control Unit based on the all new Raspberry Pi 4 Compute Module. Named after the sigmoid function, which lies at the heart of todays KI systems and artificial neural networks, the first member of the Sigmoid Series of 3D printer control units, the Sigmoid S7P, connects the two baselines of 3D printing control systems. A realtime capable low-level system for motion control and a high-level OS based system for management and HMI. Just like it´s mathematical counterpart.

Sigmoid S7P – Features

The S7P unites the very best of two worlds on a single PCB. Combining the renowned at battle-tested Raspberry Pi4 in its new Compute Module form-factor with a state of the art 32Bit realtime microcontroller gives you the most convenient way to operate your 3D-Printer.

With extensive software support for commonly used 3D-printer control software like Marlin 2.0, Klipper, OctoPrint, Repetier Host and many more, the Sigmoid S7P is the one stop shop for a fully integrated 3D printer control unit.
