S2.5 Allen key*1
Avometer*1
¶ 2.Solution:
¶ Step 1：Check the print head heater harness
1. Remove the print head housing.
2. Check whether the print head heater wire harness is loose and re-plug the print head heater wire harness.
3. The print head wiring harness inspection is completed. Set the print head temperature to 210 degrees and test for 10 minutes. If there are no further errors, it can be printed. If there are further errors, follow step 2 for troubleshooting.
¶ Step 2: Measure the hotend
1. Pull out the plug of the print head heating rod, adjust the multimeter to the on-off position (buzzer), and measure the continuity of the heating rod. If the print head heating rod emits a buzzing sound, the heating rod is normal.
¶ Step 3: Measure the heating rod port voltage
1. Pull out the print head heating rod plug and turn on the print head heating function at the same time. At this time, the terminal outputs 24V voltage and quickly measures the terminal voltage.
2. Adjust the multimeter gear to the DC voltage gear, and use the multimeter to test whether there is a 24V voltage output at the heating rod port. If there is a 24V voltage output, it is normal (when using the multimeter probe, do not short-circuit the metal probes of the two probes)。
