Stratasys - Calibrating Your F Series Printer: Ensuring Optimal Performance
Introduction: Stratasys has introduced a new standard procedure for calibrating F Series 3D printers, including models such as the F120, F170, F270, and F370. This updated calibration process implements a manual calibration step alongside the traditional auto-calibration method to address common issues, such as the "No Material Detected At Head" message.
Why Manual Calibration Matters: Previously, many users solely relied on auto-calibration, but Stratasys now mandates manual calibration before replacing a defective print head. This manual step is crucial for achieving accurate Z layer thickness readings, as the auto-calibration solely relies on a sensor within the print head.
Calibration Instructions:
Preparation:
- Begin by unloading both model and support materials from the printer.
- Ensure there is no build tray installed in the printer.
Auto-Calibration:
- Run the auto-calibration process, which typically takes a few minutes.
- The printer utilizes the plus-shaped cut-outs on the back of the Z stage to approximate X and Y offsets.
Manual Calibration:
- After completing auto-calibration, reload both model and support materials.
- Install a new, unused build tray before proceeding.
- Initiate the manual calibration process through the commands on the printer screen.
- The printer will generate a grid pattern on the new build tray.
- Inspect the printed grid pattern, noting the position of the thin line of model filament in relation to the thick support walls. (The color of the filaments will depend on what model and support materials you have loaded in your printer)
- Adjust the X and Y offset values using the sliders on the printer's calibration screen until they are within 2 thousandths of zero.
- For the final manual calibration step, measure the Z thickness by peeling off the top layer of the inner square of the calibration part.
- Measure each side of the square in the middle, calculate the average, and enter that value as the Tip Offset Z.
Conclusion:
By following these calibration instructions meticulously, you ensure that your F Series printer operates at its optimal performance level. Manual calibration, in conjunction with auto-calibration, guarantees accurate printing results and reduces the likelihood of encountering issues such as material detection errors. Implementing this standardized calibration procedure is essential for maintaining the quality and reliability of your 3D printing projects.
