- TECHNICAL SPECS -

The 4-Axis CNC Motherboard comes fully assembled and with the GRBL firmware pre-installed.
It is equiped with a dual core Xtensa 32-bit LX6 microprocessor, which operates at 240 MHz and can drive to up to 4 Stepper or Servo motors with stable and clean 120KHz pulses.

The opto-isolated terminal switches and Probe inputs, operating at 12 VDC, keeps away any external electromagnetic interference while all other outputs such as Spindle PWM, Spindle Enable, Mist and Flood coolant operate with stable and clean 5VDC.

The 12VDC power input has reverse polarity protection and ceramic capacitors, made by Samsung, to filter the input current.

Our 4-Axis motherboard is compatible with every GCode Sender applications available for the GRBL firmware. We recommend using Focus.
