uArm Swift Pro Calibration Plate

In case you need to re-calibrate your uArm robot arm and like me lost the calibration paper. I made this little handy plate that you can slide in front of the uArm to match the exact reference location.

I also found, that when you upgrade to the new v4 firmware you will need a calibration.

So how does this work?

- Launch a serial terminal like the one in the Arduino IDE
- Send the command: M2019 (this is release the motors)
- Place the uArm WITHOUT any toolhead in the calibration pl
