README
README.mdspscnc 1.1.0 CNC Controller board for FluidNC and TMC2160 controllers
There are multiple options for FluidNC, however, this project deliver a relatively low cost version of a board with Trinamic drivers, and external MOSFET's.
The board integrates components which should tolerate 20A operation on every axis, but the original prototype has only been qualified for 5A per AXIS.
The card integrates the ESP32 module, 4 axis, and a simple PWM controller for the spindle. The card integrates an isolated probe sensor which can be connected directly to the spindle body, and a connector for the 4 limit sensors.
Version 1.0.1 of the card was produced by JLCPCB. Rev 1.0.1 needs straps to become 1.0.2. Straps are removed under 1.1.0. Version 1.0.2 has been tested successfully. 1.1.0 is being released to the pulbic, but there are currently no plans to produce it as 1.0.2 is sufficient for the project owner at the moment.
Main interfaces
| Connector | Function |
|---|---|
| MAININPUT1 | Main 24V power supply input. Stepped power can be derived via solder bridge JP3 for stepper motors. |
| STEPINPUT1 | Stepper alternative power input. Requires solder bridge JP1 to be short. |
| A1-A4 | Stepper motor 4W ports. |
| MOTOR_CONN5 | Spindle motor connection (PWM) |
| J3 | +48V Spindle motor power input. |
| SPINDLE_RELAY1 | Spindle and Vacuum 24V 100mA relay control outputs (Do not connect a motor directly to this interface) |
| ISO_PROBE1 | Isolated probe connection interface. |
| J20 | Button interface port |
| Limit_IF | NC Limit switch inputs and button inputs. |

Extensions for 2 extra axis:
| Connector | Function |
|---|---|
| JP23, and JP24 | B Axis interfaces. |
| JP25, and JP26 | A Axis interfaces. |
| JP21, and JP22 | End of SPI lines for the first 4 steppers. Strapping is required if steppers A and B are to be daisy chained into the SPI bus. |
Jumpers:
| Jumper | Function |
|---|---|
| JP9 | Spindle PWM. Set for normal PWM operation, if a feedback controller is used, the feedback requires the spindle configuration to be analog instead of PWM. |
| JP23 | Solder jumper for feeding the steppers with 24V instead of 12V. NEVER Solder the 12V input and the 24V inputs simultaneously. |
| JP1 | Solder bridge for 12V operation of the steppers. See JP3 description for limitations. |

Questions
How big is the Spscnc PCB?
It measures 297.5 × 187.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Spscnc use?
491 parts, built around the ESP32-WROOM-32D, TMC2160-TA, FT232RL and IR2104PBF. 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 Spscnc KiCad files?
From the sps-EmLogic/spscnc repository on GitHub, at the commit this page was made from: the board is hw/spscnc/spscnc.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spscnc design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
