C. Check If the Extruder Runs Normally after Replacing the PC Cable.
1. Find the power switch at the bottom right on the back of the printer and turn on the switch.
2. Check if the extruder operates normally by performing the steps of loading the filament.
1）Select the “Utilities” tab on the screen.
Figure 11 Enter the “Utilities” tab.
2）Set the temperature of the nozzle to the proper unloading temperature. For example, the Raise3D PLA default loading temperature is 215℃. Here, we use the left nozzle as an example of how to perform this procedure. We set the left nozzle temperature to 215℃.
Note: The recommended loading temperature for other filaments is typically 5-10℃ higher than its common printing temperature.
Figure 12 Set the temperature of the nozzle to the proper unloading temperature.
3）Select the “Load” button and the printer will begin to heat. When it reaches the target temperature, select "Load".
Figure 13 Load the filament.
4）The extruder gear will start to rotate. Gently push the filament into the extruder. When the filament extrudes from the nozzle, click "OK" to complete the loading.
Figure 14 Gently push the filament into the extruder.
5）Confirm that the filament can extrude evenly, and then insert the guide tube back into place. Now that the printer runs normally after replacing the flat cable, you can start printing your model.
Figure 15 The printer runs normally, insert the guide tube back into place.
