I completed the build of my Maslow 4.1. While cleaning up after a successful cut I found a set screw that holds one of the gears at a specific height in the arm assembly. What is the probability of a problem if I don’t fix it?

If you found one, the odds that another will work it’s way loose is high. Go
back in and make sure they are really tight, I would cosider green (low
strength) loctite or a dab of nail polish to prevent them from working loose.

Quite low. The gear has a dshape so it will stay locked on the shaft. It might rub against the plastic on the arm a bit which will eventually cause some wear there, but I wouldn’t expect any big issues.
When I upgraded to 4.1 two of the set screws were floating around. When I reassembled I left them all out, as I figured the little bit of backlash experienced on the motor was miniscule when translated to the mechanical advantage on the spool compared to the problem they would present if they jammed the gears. So far no appreciable effect. If you do put them in, I suggest sparing use of locktite
