Step 3: Disable the Software Endstops

Search for the following line in Configuration_adv.h:

#define SOFT_ENDSTOPS_MENU_ITEM

Comment out or remove this line to disable the software endstops:

// #define SOFT_ENDSTOPS_MENU_ITEM

Additionally, locate the following section:

#define MIN_SOFTWARE_ENDSTOPS

Disable it by commenting out the line:

// #define MIN_SOFTWARE_ENDSTOPS

This ensures that the printer will not restrict movement below the Z0 position.

Step 4: Save and Compile the Firmware

After making the necessary changes:

  1. Save the Configuration_adv.h file.
  2. Compile the firmware using PlatformIO in Visual Studio Code.
  3. Upload the modified firmware to your 3D printer.

Step 5: Verify the Changes

Once the firmware is uploaded, test the Z-axis movement:

  • Home the printer and check if the Z-axis can move below Z0.
  • Use G-code commands such as G0 Z-5 to confirm that the restriction has been removed.
