Red blinking light while doing the first calibration and got an error message on one of the motors

Troubleshooting

I just assembled my M4 and am seeing a similar issue with blinking red light when I first connect. But my error message is about encoder. Here it is, please help:

Can you try fully unplugging the cable on that encoder and plugging it back in?

If that doesn’t fix it the next thing to try is to swap which port that encoder is plugged into and see if the issue moves with the encoder or stays in the same port.

You can run the test easily by pressing Setup → Test

those errors on the bottom right are saying that the cable to the encoder is not
connected fully. If you are using the ethernet cables, make sure they are fully
seated and then hit them with hot glue to hold them in place.

Ok. Thanks for the quick response. That issue seems to be due to loose cable. But I still have the red blinking light and when I press retract all nothing happens. The message says retracting all belts but none of the motors do anything.

25

A complete power cycle and extending and retracting seems to have helped. I was able to retract fully 3 belts. But the forth one did not budge. That motor is not moving at all.

26

Did release tension and after trying retract all several times that belt retracted about half way thru. but it does not retract any further.

Pressing Extend All again and extending the belt which is stuck out should help clear whatever is jamming it
