PicoBOB-DLX CNC control module
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:
https://github.com/Expatria-Technologies/Remora-RP2040-W5500
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:

Note that neither the Mach3 breakout or G540 are included, the photos are only for illustrative purposes to show how the PicoBOB-DLX can be used.
