Marlin 1.1.x or 2.x on Anet A8 Guide

thingiverse

It looks like you've provided a detailed guide on how to install and configure Marlin firmware on an Anet A8 3D printer, specifically for auto-leveling. Here's a summary of the steps: 1. **Define your controller**: `#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER` 2. Compile the code: * Select "Arduino/Genduino MEGA or MEGA 2560" as the board * Choose the correct COM port * Click on the checkmark button to compile 3. Upload the compiled code to the printer: * Plug in the USB cable and click on the -> right arrow looking icon 4. Test the printer: * Move the axis slowly to ensure everything is working correctly * Warm up the printer and verify that temperature probes are reporting correctly 5. Configure auto-leveling: * Home all axes with `G28` * Set the Z offset to 0 with `M851 Z0` and save it with `M500` * Move to the middle of the bed with `G1 X110 Y110` * Turn off software endstops with `M211 S0` * Place a bit of paper on the bed under the nozzle and preheat the machine * Lower the Z slowly until the paper is lightly pinched between the bed and nozzle * Take note of the current Z position (e.g., `Z:2.10`) and add a `-` sign to it (e.g., `Z-2.1`) * Set the offset with `M851 Z-2.1` * Enable software endstops with `M211 S1` * Save the setting with `M500` 6. Add auto-leveling to your slicer: * In the start gcode, add the line `G29 ;Autolevel` after `G28` That's it! You should now have a Marlin-powered Anet A8 with auto-leveling capabilities. Note that this guide assumes you're using a RAMPS 1.4 board and an Arduino Mega or MEGA 2560 controller. If you're using a different setup, you may need to modify the steps accordingly. Additionally, be sure to follow proper safety protocols when working with electrical equipment and hot materials.
