ARM Cortex-M3 series STM32F103RCT6 chip with 32-bit CPU 72MHz. Equipped with highly modular open source firmware Marlin2.0, convenient for users DIY and secondary development, exempt from the worries of the core code;
There are only 4 outputs (X, Y, Z and E0), but Z has to connectors because you can use two Z motors in series with the same driver. It is not possible to control ZA and ZB separately
Is it possible to set the ZB motor pins to be E1 in the pins file for this board? The pin file only shows pins for one Z?
