Hi Dale, regarding the issue that your Mooz-3 printer failed to heat up, the following information will be helpful for you to troubleshoot the cause of the failure.
When you encounter the typical and common issue that the temperature of the 3D printing nozzle does not rise, the possible influencing factors are as follows: A. Thermistor short circuit B. Short circuit of heating rod C. The circuit board is broken
In order to explain the solution more clearly, a structural diagram of the hot end is attached.
For the influencing factor of thermistor short circuit:
First of all, make sure that the thermistor circuit is not loose, and check whether the wiring of heating rod is inserted tightly. Please reinsert it, and reheat it to see if it has any effect.
At the same time, check whether the thermistor is short-circuited. If there is an obvious phenomenon that the thermistor is damaged due to the short-circuit, then it needs to be replaced.
For the influencing factor of short circuit of heating rod:
If you have spare parts for heating rods in hands, please replace the damaged heating rods with spare parts.
If there is no replaceable heating rod in your hands, after confirming that the fault is caused by the heating rod, we will arrange to send you a new heating rod for replacement.
For the influencing factor of the circuit board is broken:
If replacing the heating rod does not solve the problem, it may be related to the damage of the circuit board.
In order to confirm that the problem lies in the damaged circuit board, you need to follow the steps below:
1.Confirm whether the thermistor of the heating rod is normal.
2.Confirm whether the heating rod is normal.
If the above two parts are normal, then the problem may lie in the mainboard or the control board.
But, it is difficult to determine which of the two boards is damaged now and I need more information to confirm it.
You can use the following method to verify that the problem lie in the damaged circuit boards.
Use a multimeter to measure the output voltage of the port where the control board is connected to the heating rod.
If there is no output voltage, there is a problem with the circuit boards. At this time, new circuit boards need to be replaced to solve the problem.
