EDIT: after looking at some other forum posts, and fiddling with retraction force threshold and retract/extending a bit, i was able to fix this relatively easily.
Just completed the build of the Maslow, and doing initial calibration. The first step of calibration is to retract all belts. Using the ‘Retract All’ button in the UI, i was able to retract 3 of the 4 belts. The 4th belt does not move at all. Below is a video showing the behavior.
Are there some troubleshooting steps I can take to determine the root cause? Like logfiles, specific serial output I can capture, or some troubleshooting section of the UI?

EDIT: I’m also checking out this thread, that reports a similar issue, with much discussion:
