PicoBOB CNC control module for GRBLHAL
PicoBOB CNC control module for GRBLHAL
Credit card size GRBLHAL controller based on Raspberry Pi RP2040 microcontroller.
Standard 5V Parallel port interface. 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 can also be used with the Gecko G540 multi-axis step drive.
The default GRBLHAL builds for the PicoBOB 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.
The PicoBOB is also fully supported via the GRBLHAL web builder:
