I am having trouble with callibration and from the existing questions, seem to be encoder related. I have verified all limit switches are working. the callibration of each motor individually is also very strange, but with enough tries, they all succeed to touch the limit switch and back off. the other thing i observe is when i plug in both usb cables to the boards, the relay lights all click off. Is that expected or does that mean there is a short somewhere? I am a complete newbie to electronics, so I am looking for guidance on how to probe the limit switches with a multimeter. what are the values i should be expecting? can the enoders be probed independent of the boards? Thank you for any information you can provide. Again thank you for outsourcing the robot!
