CNC shield expansion board for 3D printer 4 x A4988 stepper motor driver with heat sink micro usb UNO R3
By Tenstar Robot
1. Latest CNC shield version 3.0
2. GRBL 0.9 compatible. (Open source firmware that runs on an UNO that turns G-code commands into stepper signals)
3. PWM Spindle and direction pins
4. 4-Axis support (X, Y, Z , A - duplicate X,Y,Z or do a full 4th axis with custom firmware using pins D12 and D13)
5. 2 x End stops for each axis (6 in total)
6. Coolant enabled
7. Uses removable A4988 or DRV8825 compatible stepper drivers
8. Jumpers to set the micro-stepping for the stepper drivers. (Some drivers like the DRV8825 can do up to 1/32 micro-stepping)
9. Compact design
10. Stepper motors connected with 4-pin molex connectors or soldered in place.
11. Runs on 12-36 V DC. (At the moment only the DRV8825 drivers can handle up to 36 V so please consider the operation voltage when powering board.)
12. Please note that this is an unassembled kit and basic soldering skills are needed.
A4988 stepper motor driver:
1. A4988 stepper motor driver board is a breakout board for Allegro's A4988 DMOS micro stepping driver with translator and overcurrent protection; please read the A4988 datasheet carefully before using product.
Low RDS (On) output
2. Automatic current decay mode detection / selection
3. Mix with slow current decay modes
4. Synchronous rectification for low power dissipation
5. Internal UVLO
6. Crossover-current protection
7. 3.3 and 5 V compatible logic supply
8. Thermal shutdown circuitry
9. Ground fault protection
10. Load short-circuit protection
11. Five selectable step modes: full, 1/2, 1/4, 1/8 and 1/16
