Overview
This is a fully modular CNC controller that runs Grbl_ESP32 firmware.
Current Source Files.
The latest versions are now on OSHLabs with the free version of EasyEDA. I did this to make it more accessible and easier to order.
Features
- ESP32 Sockets to fit both narrow and wide 2 x 19 pin types.
- (6) Stepper Driver Outputs. These can be used for 6 axes (XYZABC) or any (2) can be ganged to allow dual motors on a single axis. These ganged motors can be controlled independently for axis squaring. It supports these types of drivers. Each driver has an independent enable/disable pin.
- Standard Pololu/StepStick style driver modules.
- Trinamic SPI type drivers. These are the ultra quiet types with sensorless endstop capability.
- External Driver with 5V opto isolators. (5) CNC I/O Modules. These interface with your machine. They include, but are not limited to, siwtch inputs, spindle control and accessory control. Currently there are (5) modules available.
- High current AC/DC relay
- 4x 5V Buffered output for lasers, PWM, spindle direction, spindle enable, ect.
- RS485 Modbus Spindles
- 0-10V Output Spindles
- 4x Switch input with Optocouplers, filtering and Schmitt triggers.
- SD Card Socket
- JTAG Programming/Debugging connector (or access to addition I/O pins

Questions
How big is the High Current Analog PCB?
It measures 33 × 25.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the High Current Analog use?
10 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the High Current Analog KiCad files?
From the bdring/6-Pack_CNC_Controller repository on GitHub, at the commit this page was made from: the board is CNC_IO_Modules/High_Current_Analog/source/High_Current_Analog.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the High Current Analog design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
