-Recently, some customers have put forward some new ideas about the 3.3V failure. I recommend you can try it before you power up your spider. Glad that you can provide us with some feedback data, which will help us to make further judgments.
+Recently, some customers have put forward some new ideas about the 3.3V failure. I recommend you can try it before you power up your spider. Glad that you can provide us with some feedback, which will help us to make further judgments.
 
 Reason: 3.3v burning problem may be caused by residual power on the motherboard.
 
 Analysis: The front end (`MAIN_PWR`) on the spider motherboard has a large capacitor of `470uF`, and each drive position (`VMOT`) has a capacitor of `100uF` (a total of 8). `VMOT` and `MAIN_PWR` are connected through a diode. During the factory test, the main board is powered on, and the power is turned off after all functions are tested.
-At this time, there is still stored electrical energy on the motherboard. The electrical energy of `MAIN_PWR` can be consumed by peripherals such as connected LEDs. However, due to the existence of diodes, the electrical energy of `VMOT` is not consumed by external devices and may exist for a long time (not sure long).

However, due to the existence of diodes, the electrical energy of `VMOT` is not consumed by external devices and may exist for a long time (not sure how long).
 Moreover, after some customers get the board, they will power on without plugging in the driver. After checking, plug in the driver and then power on. Such process will store electrical energy again, and there is not enough time for the electrical energy to be released.
-In this case, the insertion of the driver is equivalent to operating with electrical energy, and there is a high probability that the drive will be burned (the rated voltage of the 2209 is inherently low).
+In this case, the insertion of the stepper driver is equivalent to operating with electrical energy, and there is a high probability that the stepper driver will be burned (the rated voltage of the 2209 is inherently low).
 
-Corrective action: Discharge the power of the motherboard before inserting the driver.

 1. Power off the motherboard completely (remove the wiring completely), and wait for the 24v, 5v and 3.3v LEDs to be completely off.
 2. Connect a 100K resistor (or a cable) to the +/- pole of `MAIN_PWR`.
