recore

Recore is a 3D-printer control board with six TMC2209 stepper drivers, 30A maximum current load, an Allwinner A64 quad core 64 bit SoC. It's in early development stages, but the idea is to make video updates on the progress of the project. The bulk of the design was done in August 2019 with the first prototype done in September. The plan is to use about six months for the testing and implementation of the complete design.

This project builds upon the work that was done with Replicape and Revolve (which was never mass manufactured). The form factor is the same as Revolve, but the platform is different.

Here is the schematic for revision A2. This board has not yet started selling, so it's just for reference:
