Please note that while the PicoBOB-DLX hardware is tested and fully functional, the software (especially LinuxCNC/Remora) is still under active development.

Standard 5V Parallel port interface for many CNC machines and peripherals.  When combined with Mach3 Breakout Board, has the following features:

  • 5 axes of step/direction control
  • 10A Spindle Relay
  • 0-10V Analog spindle speed control
  • 5 opto-coupled inputs
  • One 24V output 

The PicoBOB DLX can also be used with the Gecko G540 multi-axis step drive and supports all of the I/O on that device.

Host communication is via Ethernet or USBC connectors.

When combined with the Remora RP2040-W5500 component, the PicoBOB DLX can be used as an ethernet attached step generator with LinuxCNC.  For details, the Expatria development branch is located in this repository:

The default GRBLHAL builds for the PicoBOB DLX include the following features that are implemented in the RP2040 port of GRBLHAL:

  • Backlash Compensation.
  • Stress-free Auto-squaring for the ganged axis
  • Ganged axis offsets to correct for offset homing switches
  • Step rates tested up to 180 KHz on 5 simultaneous axes.

For details, the Expatria development branch of the GRBLHAL RP2040 driver is located in this repository:
