Introduction to the OpenBuilds BlackBox Features

1. Front Side

  • a) USB LEDs: Flashes in Blue/Green to indicate serial data transmit/receive traffic
  • b) Power Switch: Used to turn the Main Power off, can be used in case of an emergency to bring the machine to an immediate stop
  • c) Status LEDs
    • Door LED: On when the Door input signal is active
    • Tool On: Indicates the Tool is Enabled (Also Relay1)
    • Tool Rev: Indicated Tool Direction is reversed (Also indicates Relay2)
    • Tool PWM: Shows the proprotional RPM or output power of the PWM/0-10v outputs
    • Coolant LED: Shows status of the Coolant signal (M8 = on, M9 = off)
    • Probe LED: Lights up when the Probe Input activates
    • Motors Enabled LED: Indicates when the firmware has the Motor Drivers Enabled. In Grbl Settings set $4=1 (required for BlackBox drivers to function correctly) and $1=255 (to keep motors always enabled)
  • d) Mode and Reset Buttons: Reset: Restarts the Firmware; Mode button used to put microcontroller into Bootloader mode
  • e) Power LED: If the Power LED is Green: Power Input OK
  • f) Current Adjustment: Adjust stepper driver current, see Section 2.2.1 Current Adjustment
  • g) Fault Indicators: Indicates a problem with the stepper driver on the relevant axis: The LED indicates
    • Overtemperature Fault: Adjust current down a little, Check Fan
    • Overcurrent Fault: Adjust current down a little
    • Short Circuit Fault: Check Wiring
    • Undervoltage: Check input Voltage

2. Left Side

  • a) USB: Port for connecting the controller to your computer
  • b) 0-10v Calibration: Used to calibrate the 0-10v Spindle control signal
  • c) Interface Port: For connecting to accesories
  • d) Door Switch Input: (Advanced feature) Refer to Section 3.6 Connect Door Sensor
  • e) Servo: Used for pen-plotter applications: See Section 3.3.6 RC Servo
  • f) Relays
    • Relay 1: Normally Open SPST relay, by default configured as Tool Enable (Plasma trigger, VFD Enable, etc)
    • Relay 2: Normally Open SPDT relay, by default configured as Tool Direction (VFD Direction, etc)
  • g) 0-10v Output: Typically used with VFD Spindles. See Section 3.3.5 0-10v Analog Signal / VFD
  • h) Tool Enable: 0/3.3V signal reflecting tool on/off state. Typically used as a logic signal for switching a Mains relay / IoT relay for spindle control
  • i) Tool PWM: 0-3.3v PWM signal reflecting tool rpm/power. Typically used a PWM signal for DC motor controllers, Lasers, etc
  • j) Coolant: General output, switchable with M8/M9, refer to Section 3.7 Coolant Output
  • k) Power Input: Connect to 24v Power Supply. Double check polarity before powering on. See Section 3.1 Connect Power Supply
