Steps to Calibrate Your Extruder’s E-Steps
It’s time to explore the calibration process. Follow these steps carefully to ensure accurate e-steps calibration.
Opening Cura and Connecting Your Printer
The first step is to open Cura software on your computer and navigate to the “Monitor” section. This section allows you to interact with your 3D printer. Make sure you have Cura version 5.2.1 or later installed.
Preheating the Extruder and Sending G-Code Command
Clearly, preheating the extruder is imperative for accurate calibration. Set the extruder to a temperature of 200°C and preheat it. This temperature is suitable for most filaments, but you can adjust it if necessary.
Your printer should now be preheated and ready for the next step. Mark 120mm of filament before the extruder using your jig and marker. In the Cura command line, enter the following G-Code command to extrude 100mm of filament: G1 E100 F100. This command will help you determine if your printer is under or over-extruding.
Measuring Filament and Determining Under/Over-Extrusion
Command your attention to the remaining filament after executing the G-Code command. Measure the length to determine if your printer is under or over-extruding. This step is crucial in identifying any issues with your extruder’s e-steps.
Determining the correct extrusion rate is vital for achieving high-quality prints. Take your time to measure the filament accurately, and make a note of the results.
Using Notepad++ to Edit G-Code
Your next step is to download and install Notepad++, a free text editor optimized for working with G-Code. Copy the G-Code provided into a new file in Notepad++.
Measuring the effectiveness of your G-Code edits is crucial. Use Notepad++ to modify the G-Code file according to your needs, and save it for later use.
Saving and Transferring G-Code to the Printer
Little by little, you’re getting closer to calibrating your extruder’s e-steps. Save the G-Code file as e95.gcode on an SD card and insert the card into your 3D printer.
GCode files are imperative for communicating with your 3D printer. Make sure to save the file correctly and transfer it to the printer to avoid any issues during the calibration process.
Running and Adjusting the G-Code
Unlike manual calibration methods, using Cura to calibrate your extruder’s e-steps allows for a more precise and efficient process.
Running the Initial G-Code and Measuring Results
With the G-Code file saved and transferred to your 3D printer, run the e95.gcode file and measure the remaining filament. This will give you an idea of how accurate your current e-steps are.
Calculating New E-Steps and Adjusting the G-Code
There’s a simple formula to calculate the new e-steps based on the actual extruded length: New Steps = (100 * Current Steps) / Actual Extruded Length.
Running this calculation will give you the new e-steps value, which you’ll need to adjust in the G-Code file. For example, if the calculation suggests changing to M92 E108, update the G-Code file accordingly.
Saving and Running the Adjusted G-Code
Adjusting the G-Code file with the new e-steps value, save it as e108.gcode and transfer it to the SD card. Mark another 120mm of filament and run the new G-Code file.
The results should now be more accurate, with the remaining filament being within ±1mm of 20mm. If not, repeat the calculation and adjustment process until you achieve consistent results.
Entering E-Steps in Cura and Testing
Despite having calculated and adjusted your e-steps, you still need to update your machine settings in Cura and test the results.
Updating Machine Settings in Cura
If you haven’t already, go to “Manage Printers” in Cura and select “Machine Settings.” Add the following line to the end of the start G-Code to override the e-steps in the EEPROM for all prints: M92 E108.00. This will ensure that your newly calculated e-steps are applied to all future prints.
Printing a Test Model and Validating Results
Any changes you make to your e-steps should be tested by printing a model that showcases the extrusion quality. This will help you identify if your printer is under or over-extruding.
It’s imperative to carefully observe the print quality during this test. Look for signs of under-extrusion, such as gaps or weak layer adhesion, or over-extrusion, which can cause oozing or blobs. If you notice any of these issues, you may need to further adjust your e-steps and repeat the testing process until you achieve consistent results.
Tips for Successful Calibration
To ensure a successful calibration process, keep the following tips in mind:
- Make sure your printer is properly leveled and calibrated before starting the e-steps calibration process.
