uArm Metal doesn't work after upload firmware

1

I got an uArm metal a couple of days before. It worked fine at the beginning with the uArm client. Then i tried to upload the Calibration firmware to uArm by Arduino IDE. The upload seems good, but the uArm doesn’t work after I uploaded the firmware. It no longer moves. Then I tried to uploaded the standard firmware from this link : https://github.com/uArm-Developer/FirmataEEPROM/releases. The upload seems fine. The serial port seems fine too, because i saw the LED blinking when i manipulate the arm by uArm client, but the arm doesn’t move at all.

Now i am really confused that is my uArm broken?

How can I reset it to the out-of-box status? Is the initial calibration necessary?

Thanks.

If your goal is to move the arm using code on the uArm Arduino, you need to be using this library:

Make sure you first calibrate the arm using the method shown on this page:
http://developer.ufactory.cc/quickstart/

Use the “Calibration” example from the above library to do the calibration.

Note that the calibration for this Arduino firmware is different than the calibration for the “learning mode” etc.
