Wiring through flexing cable carriers (chain) is simpler with industry standard flat CAT-7 cables. Connections for each axis go through one RJ-45, featuring 9-pins (including shield) allowing more flexible setup for larger systems with longer cable runs. The hardware design for the F46 features 12 RJ-45 “ethernet” connectors for connection to all peripherals. With a 32-bit Arm Cortex-M4 core overclocked to 240MHz, the STM32F407VET6 (192kB RAM, 512kB flash) brings professional grade CNC control to the world of GRBL. The GRB元2 firmware is a fork from GRBL version 1.1f, running on the 32-bit STM32F407VET6. The F46 is running GRB元2 (an upgrade from the popular GRBL firmware running on an Arduino 328p processor). With the faster pulse rate, more advanced stepper drivers can be used (featuring up to 256 micro-steps/full-step) without sacrificing feed rate. Applications include CNC, Pick-and-Place, and Robotics. Additional controls are available via I2C and SPI. Advanced features include: high pulse rate (550+ KHz), additional PWM (8X), digital inputs (8X), and digital outputs (8X). The F46 is well suited for complex CNC or Robotics where motion control requires more than 3 coordinated axis of motion.
