Up to 5 axes of step/direction control.The PicoBOB closely tracks the features of the Mach3 BOB: It is our hope that the community finds the design useful and that it may be carried forward to help advance the PrintNC and broader CNC hobby community. The design is free to use by all parties, including commercial parties, under the CERN-OHL-S V2 license. The complete BOM and fabrications files are in the CAM_OUTPUTS folder for upload.

The PicoBOB can be easily sourced from JLCPCB. It uses a Raspberry Pi RP2040 MCU and the widely available 5 axis Mach3 breakout board. It is intended to be simple and low cost. The PicoBOB allows you to use the high performance GRBLHAL motion control system with a traditional Mach3/LinuxCNC parallel-port breakout board. Please consider buying a board to support our open-source designs. Expatria Technologies PicoBOB GRBLHAL module
