This might be a dumb question, but are we talking actual different voltage levels, or different PWM duty ratios? Have you ensured that you have set (from code) the power levels of all the ports to be the same? How have you observed the difference - and to what degree is it?

Without any precious hardware verification, this is what I did: - symptom: motor C was not able to make turn as well as motor A can - troubleshooting steps: a) to ensure even load on both motor ports, I removed all other attachments, and left (...)

		different output power at different ports?
I just confirmed that some RCX happens to allow various output power to different output ports. In my case, the port A tends to produce more power thru motor and the port C does. I then switched the two motors. The condition stays the same. (...) (19 years ago, 14-Jul-05, to lugnet.robotics.rcx, lugnet.robotics.rcx.robolab)
