Pidog v2 calibration

I assembled the pidog v2 completely and started the calibration. When I got to the 4th leg, I realized I connected one of the thigh servos incorrectly. I fixed that. In order to zero the re-aligned servo, do I need to disconnect all the other servos, so they’re also not zero’d out? Or does it matter?

That’s not necessary. Simply re-zero the servos that were connected incorrectly, then proceed to perform the calibration for all servos again.
