Raspberry Pi CNC Hat V2.60 - GRBL v1.1 Compatable - Uses Pololu Stepper Drivers:
New in Version 2.60
- Added a I2C Grove connector that connects to the Raspberry Pi's I2C pins(3.3V only). This makes it very easy to add Grove sensors , inputs or outputs directly to the raspberry Pi.
- Cleaned up design with embedded Arduino Uno compatible micro-controller (ATMEGA328).
- The hat can now be programmed directly from the Raspberry Pi.
- Pre-loaded with the latest GRBL firmware v1.1.
- Compatible with other firmware like Firmata for use in robotic / automation projects.
- GRBL V1.1 PWM compatible. (Open source firmware that turns G-code commands into stepper signals)
- 3 Axes (XYZ) +4th that can clone X/Y/Z
- Added circuitry for End-Stop and Probe signal filtering. This eliminates false triggers and makes it possible use non-shielded cable for end-stops/probes.
- Breakout pins to connect external Stepper Drivers like Gecko Drivers.
- Uses removable Pololu A4988 compatible stepper drivers. (A4988, DRV8825 and others)
- Uses removable screw connectors to make it very easy to wire up.
- End Stop for each Axis and Probe.
- Variable Speed Spindle / Laser Intensity control (PWM Spindle pin and Direction pin)
- Coolant control pin. (Extra output pin)
- Jumpers to set the Micro-Stepping for each stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping )
- Runs on 12-30V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
- Assembled board ready to run.
- Compatible with Raspberry Pi Models :
- Raspberry Pi 3 and B+
- Raspberry Pi 2
- Raspberry Pi B+ (The one with the 40 pin headers.) (It is possible to use the Raspberry Pi Zero but the board will need extra style="font-family: Arial; font-size: 14pt;">
- Assembled Raspberry Pi CNC Hat
- Green removable screw connectors. (7 in total with each having 4 pins)
- Copper Mounting Spacers and screws
