UNO for Arduino———————- expansion board
- 8 ———————— EN (stepper motor driver enable active low)
- 7 ———————– Z.DIR (Z -axis direction control)
- 6 ———————– Y.DIR (Y -axis direction control)
- 5 ———————– X.DIR (X -axis direction control)
- 4 ———————- Z.STEP (Z -axis stepper control)
- 3 ———————- Y.STEP (Y -axis stepper control)
- 2 ———————- X.STEP (X -axis stepper control)
Features
- GRBL 0.8c compatible. (Open-source firmware that runs on an Arduino UNO that turns G-code commands into stepper signals)
- 4-Axis support (XYZA-Can duplicate XYZ or do a full 4th axis with custom firmware using pins D12 and D13)
- 2 x End stops for each axis (each axis pair shared by same IO pin)
- Spindle enable and direction connection.
- Coolant enable connection.
- Uses removable Pololu A4988 compatible stepper drivers, e.g. A4988, DRV8825 and others (not included)
- Jumpers’ headers to set the Micro-Stepping for the stepper drivers.
- Compact design.
- Stepper Motors can be connected with 4 pin dupont/molex connectors.
- Runs on 12-36V DC. (At the moment only the Pololu DRV8825 drivers can handle up to 36V so please consider the operation voltage when powering the board.)
