PCB hardware design about copper thickness

[lwxtp1985]

For 7DOF humanoid arm project, the total current look like very high, so how much copper thickness is needed to the PCB？2 oz is it enough？ or other suggestions？

Currently it is 1oz and experiments have not shown any problems.
We will continue to look for a better setting.
