The quality of the first layer is crucial for 3D printers. If the first layer is not properly laid, it can lead to overall printing failures for the entire model.
In this section, we will discuss the reasons behind a too low first layer during printing and provide solutions. When we refer to a "too low" first layer, it means that the distance between the nozzle and the build plate is too close, resulting in issues such as "peeling," "bulging," and "wavy lines" during the first layer printing process.
The figure below illustrates the phenomenon.
It is crucial to perform heatbed leveling, particularly when changing or replacing the printing plate, to ensure accurate leveling for the new task.
Neglecting this step can result in discrepancies compared to the previous leveling data.
If the position of the hotend changes, it can lead to inaccurate leveling data.
It is recommended to run bed leveling before printing, especially when changing or replacing the PEI printing plate.
This is required for best results, and will ensure consistent first layer results.
You can do so by enabling the Bed Leveling feature in the slicer, right before starting a print.
If bed leveling is performed during the current printing and no improvement is observed, you can try tightening the secure screws of the hotend heater screws.
Start by confirming that the hot end temperature is below 50 C by checking the screen.
Next, turn off the printer and remove the front cover. Follow the instructions on the guide sticker to remove the hot end.
In the next step, remove the 3 screws that secure the heater assembly using an H2.0 hex key.
Flip the heater assembly over to access the 4 small screws at the back and use an H1.5 hex key to retighten the screws as shown in the images below.
Please be cautious as these screws are relatively small.
Reinstall the heater assembly and the hot end, then restart the printer for printing.
Remember to perform bed leveling before starting the first print.
