How to calibrate the various axes of the FDM printer

[Sabine]

Calibrating the various axes of the printer is a key step in ensuring the accuracy and quality of 3D printer printing. The following are the steps to calibrate the printer's axis in general:
First, the X-axis and Y-axis calibration. First, print a simple test model, such as a square or grid, in order to evaluate the accuracy of the printer's X and Y axes. Use a tape measure or micrometer to accurately measure the size of the printed model and compare it with the design size. If the size of the printed model deviates from the design size, you may need to adjust the printer's step spacing or stepper motor Settings. This can usually be adjusted through the printer control panel or printer software. Make sure that the belt of X and Y axis is properly tensioned, improper tightness will affect the printing accuracy.
Then there is Z-axis calibration. Print height calibration model: Print a height calibration model, such as a vertical wall, in order to check the accuracy of the Z-axis. If the print height deviates from the expected, you may need to adjust the Z-axis step or the position of the end switch to ensure the accuracy of the height of each layer. Ensure that the Z-axis guide rod and guide rail are free of foreign objects or impurities to ensure smooth movement.
Finally, there are a few other caveats. If you have the fine tuning function, you can further adjust the accuracy of each axis by fine tuning. After the adjustment is completed, it is recommended to print the test model several times for verification to ensure that the adjustment effect is in line with expectations.
Calibrating the various axes of the printer requires patience and care, and I hope you can do it. Only in this way can the FDM Printer make corresponding adjustments according to the actual situation of the printed model until the printing accuracy is satisfactory.
