First Print
In the previous section, we covered the process of slicing STL files and uploading them for printing. This section will focus on key considerations for your first print and any necessary adjustments.
Initiating the Print
Upon starting the print, the nozzle and platform will begin to heat to the predetermined temperature, while the hotend fan activates. The Z_TILT leveling process will follow.
Once leveling is complete, the hotend will extrude filament to draw a straight line on the platform, signaling the commencement of the print.
During your initial print, it is essential to pay particular attention to the quality of the first layer, as this significantly influences the success of subsequent layers. If the initial printing distance is excessive, the model may fail to adhere properly to the platform, potentially leading to detachment.
Refer to the image below to determine whether the nozzle is too close to or too far from the platform. Adjust the Z-offset using the display screen or the web interface. Once you have made the necessary adjustments, you can click "Save Configuration" after the print is complete. This will ensure that the settings are retained and applied for future prints.
A negative offset value will bring the platform closer to the nozzle.
A positive offset value will move the platform further away from the nozzle.
If the offset value is too high and adjustments can't be made in time, you can stop the print, clean the platform, and restart the process.
If the Z-offset seems correct but the print won't adhere, it may be due to industrial oil or wax on the surface. Use a degreasing cleaner to clean the platform. If adhesion decreases over time, lightly sanding the surface with fine-grit sandpaper can help restore its stickiness.
After completing the first layer print, the part cooling fan will start working. Depending on the material used, the fume pack and auxiliary part cooling fan may also be activated. If the machine is properly installed and the slicing software is correctly configured, the first print may not be perfect, but it should be able to complete normally.
