2.5 Connecting BLOX to Stepper Motors
OpenBuilds BLOX provides support for 2x Bipolar Stepper Motors, with software-controlled current setting and fault monitoring.
- Motor Max Current: 3.2A
- Motor Voltage: 3V ideally, higher will limit acceleration
- Motor Inductance: 1-2mH ideally, higher will limit max speed
2.5.1 Wiring
Note: The color codes shown below only apply to OpenBuilds Motors. Refer to FAQ: Identify Motor coils to identify the coil pairs or if you have issues with motors not working correctly.
| BLOX Terminal | Device |
| A+ | Coil 1 (Red) |
| A- | Coil 1 (Blue) |
| B- | Coil 2 (Green) |
| B+ | Coil 2 (Yellow) |
 | IMPORTANT WARNING: Note: Never connect/disconnect motors to a powered-up controller. Always turn off power before connecting/disconnecting accessories to/from your BLOX |

2.5.2 Configuration
2.5.2.1 grblHAL/CONTROL
Make sure to set grblHAL settings (CONTROL > Grbl Settings Tab)
- $140=xx X-Axis Motor Current (Set appropriate current for stepper motors in use)
- $141=xx Y-Axis Motor Current (Set appropriate current for stepper motors in use)
- $4=0 ;Step direction invert = disabled (Required)
- $1=255 Step idle delay = set to always enabled (Recommended, keeps motors locked to maintain position)
