GRBL CNC Robotics Controller 6 Axis GRBL32 STM32F407 STM32 ARM 32-bit USB 500KHz

The F46 is well suited for complex CNC or Robotics where motion control requires more than 3 coordinated axis of motion. Advanced features include: high pulse rate (500+KHz), additional PWM (8X), digital inputs (8X), and digital outputs (8X). Additional controls are available via I2C and SPI. Applications include CNC, Pick-and-Place, and Robotics. The F46 is running GRBL32 (an upgrade from the popular GRBL firmware running on an Arduino 328p processor).

The GRBL32 firmware is a fork from GRBL version 1.1f , running on the 32-bit STM32F407VET6. 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 hardware design for the F46 features 12 RJ-45 ethernet connectors for connection to all peripherals. 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.

Wiring through flexing cable carriers (chain) is simpler with industry standard flat CAT-7 cables. CAT-5 and CAT-6 cables can be used where the shield connection is not required. CAT-7 is recommended for longer cable run. With CAT-7, cable length of up to 10 meters has been tested. Customer can request legacy 115.2K baud firmware.

DC Power Input: 6 to 12V. Twelve (12X) RJ-45 Connectors to the following peripherals via breakout boards. Six (6X) Axis Output (RJ-45), each: STEP, DIR, Enable, Limit P, Limit N, Home. The AB1 will output the control signals, the AD1 will accept a Pololu-style driver. Connectors: 3.5mm green screw terminals. CNC Control connection (RJ-45) : Control Reset, Safety Door, Cycle Start, Feed Hold, Emergency Stop, Probe. Two (2X) PWM Output (RJ-45): PWM1, 2, 3, 4; and PWM5, 6, 7, 8. Breakout: PW4 for RC Servos, BB1 for others.

Connectors for PW4: 3.5mm green screw terminals for external power. Standard 0.100 3 male pins for RC servos.

Spindle Control (RJ45): Spindle (Laser) PWM, Spindle Direction, Spindle Enable, Coolant Mist, Coolant Flood. Digital Output (RJ45): AUX1, 2, 3, 4, 5, 6, 7, 8. Alternate Comm: SPI and I2C.

Digital Input (10 pin Male Header): Digital in 1, 2, 3, 4, 5, 6, 7, 8. Raspberry Pi Zero (W) Interface: 10 pin Male Header. SPI Interface (duplicate of above Alternate Comm): 8 pin Male Header.

I2C Interface (duplicate of above Alternate Comm): 6 pin Male Header. F46 with Enhanced GRBL32 features. The axis are: XYZ ABC.

Up to 550KHz pulse rate for each axis while under 6-axis coordinated motion, 750KHz max pulse rate when running 3-axis or less (more than an order of magnitude from 30KHz for Arduino based GRBL). Smoother Acceleration/Deceleration (0.2 ms accel/decel step). 240MHz timer for flexible PWM output control (Spindle or Laser). Default is 10KHz PWM at better than 14-bit resolution : 24000 steps in the 0 to 5V range.

Multiple connectivity options: USB (onboard CH340), External UART, WiFi (ESP-01), or Raspberry Pi Zero W (WiFi). Running at 921.6K baud-rate. Separate input pins for positive and negative travel limit switches for each axis, allowing the use of active high optical photo-interrupters (typical GRBL systems have both limit switches on one input pin). Eight (8) AUX TTL outputs (M-Code control: M62, M63).

Eight (8) Digital Inputs (wait for input M-Code control: M66). Eight (8) additional PWM outputs. One application is driving PPM devices such as RC Servo motors (M-Code control: M67). Custom Acceleration Scaling (custom M-Code control: M100), allow in-code changes in the acceleration parameter for each axis individually.

I2C and SPI Controls for expansion (via M-Code controls). Summary of connection breakout module types.
