It appears that you've provided a long text about the conversion process of an Ender 3 printer, specifically focusing on the steps to perform a thorough check and calibration of the printer's components. Here are some key points summarized for clarity: ### 1. Checking Limit Switches - **Goal:** Ensure limit switches are working correctly. - **Steps:** - Enter "M119" in the terminal and press Send. - Check the status of the limit switches. - If a switch is not activated, manually press it while observing the feedback on your screen until it says "TRIGGERED". - Repeat this process for all three limit switches. ### 2. Stepper Calibration - **Goal:** Verify the stepper motors are functioning as expected. - **Steps:** - Push each axis (X and Y) to its center by hand and press once on the marked fields. - For X, the motor should move right when clicking +X10mm. Repeat for Y but remember that Z only moves upwards initially because it hasn't been homed yet. - Use GCODE M119 after pushing each axis to check if they are triggered properly. ### 3. Homing the Axes - **Goal:** Ensure all axes can correctly home and move to their limits. - **Steps:** - Once you've verified the stepper motors, home the X-axis by following the instructions in your terminal window. - Repeat this process for Y, ensuring it also homes properly. - After both are successfully homed, proceed with homing Z. ### 4. Heater and Extruder Testing - **Goal:** Verify that heaters and extruder are working as expected. - **Steps:** - Select a temperature of 60 degrees for the nozzle to check if the Hotend fan turns on automatically when it rises above 50 degrees. - Next, set the bed to 40 degrees and ensure it heats up correctly. - Finally, heat up your nozzle to about 200 degrees while inserting filament. The extruder should push out 5mm of filament upon reaching temperature. ### Final Steps - **Goal:** Complete any final tasks before using the printer. - **Steps:** - Once everything is functioning as expected, you can start printing or continue testing further. - Before printing or further use, screw in the cover with the fan over the electronics box to its original mounting holes. This conversion aims to significantly reduce noise from the Ender 3 printer by replacing noisy fans and adjusting various components for smoother operation.
