payload is close to capacity

Post the exact error code with description. I'm guessing "MOTN-170 Load is close to capacity?" This is just a warning and shouldn't be preventing you from running. You can get a more complete description with corrective steps by selecting the message on the error screen and hitting "Shift+Diag." But in any case when you get an error, you should try to understand what it's telling you and what the root cause is - not jump straight to bypassing it. The manufacturer put it there for a good reason, not just to annoy you.

I recommend searching this forum for "Payload" and "Inertia." You'll learn a lot about payloads, how to set them, how they effect performance and robot life, etc. If you still have questions, post them here along with information about your situation (What robot, what your payload settings are, what you're doing with it, etc)

You can't bypass reality.

Close to capacity is just a warning. Why would you be that bothered by it? I recommend you double check that your payload settings are accurate.
