FAQ¶
About the Assembly¶
Q1: After assembly and program download, the Rollarm’s four axes are in wired position, some maybe out of control. What should I do?
Remember to power on and calibrate each Servo before assembly, please refer to Calibrate the Servo Angle.
If it has been calibrated, but after running
Rollarm.ino
, it is at the angle shown below, but if you screw all 4 potentiometers to the forward-facing position and can return to the way it was just assembled, it is normal.

If a new folder has been created for the subprogram, please cut the subprogram file to the original directory Arduino code\\Rollarm
. Reopen the main program:
