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:https://github.com/Expatria-Technologies/RP2040 For complete documentation on this OSHW design, see this Github repository:https://github.com/Expatria-Technologies/PicoBOB_DLX Note that the Mach3 breakout, G540, or USB cable are not included, the photos are only for illustrative purposes to show how the PicoBOB-DLX can be used.
