- 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.
- Bigger Solder pads making it easier to assemble.
- Probe pin labels have been updated to make it easier to install a probe.
- GRBL v1.1 compatible. (Open source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals) (Check down for more info)
- Uses removable A4988 compatible stepper drivers. (A4988, DRV8825 and others) (Not Included with this shield)
- PWM Spindle and direction pins
- 4-Axis support (X, Y, Z , A-Can duplicate X,Y,Z or do a full 4th axis with custom firmware using pins A4 and A3)
- 2 x End stops for each axis (6 in total) + one Probe
- Coolant enable output
- Jumpers to set the Micro-Stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping )
- Compact design.
- Stepper Motors can be connected with 4 pin molex connectors or soldered in place.
- Runs on 12-36V DC. (At the moment only the DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
Jumpers color may vary depending on the available stock.
FREQUENTLY ASKED QUESTIONS:
- What is GRBL?
- An open source, embedded, high performance g-code-parser and CNC milling controller written in optimized C that runs on an Arduino UNO.
- What projects can this be used for?
- Small CNC routers, DIY Laser Cutters, 3D Printers and almost any project where you need to control a stepper motors with high precision.
