Great work! @G-Pereira 👏

Hi, I am planning to replace the Arduino Grbl with your 4_Axis_SPI_CNC board to support TMC5160 drivers and add a 4th axis to my CNC. Initially I thought of using...

In the schematic I noticed that the **Step/Dir** pins are physically connected to the ESP32 board. Do we need them for **SPI connection**, if they are not needed we can...

Hi, I have created a schematic with a slightly different pin map. **RC filters** are added for limit switches to be able to use with large machines.  [Schematic_esp32 grblcnc...

  Here are some photos, Everything works well except the `TMC5160 SPI connection.` P.S: Board named after the project creator @bdring.

Yeah sure, Most of the connections are similar to your 4 axis SPI board.  The extra headers are allow us to configure SD and SPI connections Since I'm using...

**Thanks @bdring**, I have tried connecting the **CLK to ground**. Nevermind the headers in the schematic. Those extra headers are used to configure **Microsteps or SPI** connections with the help...
