Intelligent Agent previously released a $99 Replicape 3D printer controller add-on for the BeagleBone Black.Īs noted by the CNXSoft post that alerted us to the Recore, most 3D printers are powered by MCUs and do not include an application processor running Linux. The project shows benchmark results with a much faster step rate (with 3x active steppers) compared to major MCU based controller boards or the BeagleBone PRU, which plays a similar real-time role on BeagleBone based 3D printing solutions.
With the help of a proprietary Allwinner blob, the AR100 typically provides power management services to Linux. The open source AR100, also known as ARISC, is an OpenRISC 1000 architecture coprocessor that appears on modern Allwinner SoCs. Although the FAQ suggests there is also an STM32 MCU on the Recode, the board taps the Allwinner H64’s 32-bit, 300MHz AR100 core for “fast realtime aspects, mainly the stepper motors.” The Recore A5 has a 1GHz, quad-core, Cortex-A53 based Allwinner H64 SoC, which we have seen on Linux hacker boards such as the Banana Pi BPI-M64 and Pine A64.

The product is still in development and targeted at early adopters and software developers assisting in the Recore project. Norway-based Intelligent Agent has begun selling the 5th Gen model of its open-spec Recore 3D printer control board for $149. The SBC provides 6x stepper motor drivers, 3x heater outputs, a heated bed, 4x USB, and GbE and HDMI ports. Intelligent Agent’s $149 “Recore A5” 3D printer board runs Linux on an Allwinner A64, using the SoC’s AR100 core for real-time control.
