put the sled near one of the bottom corners,and you will see that the line going to the opposite corner will have a much flatter angle than the one going to the near corner. That will mean that there will be more force pulling away from the corner than pulling into the corner. This is exactly the opposite of what we need to have happen and make the problem worse.

Much like spreading the motors farther apart and raising them higher above the working surface lessens that, I planned to move the pulleys at least as far apart as the motors and below the bottom edge as far as I put the motors above. Has anyone tested this?
I’m not discounting what you are saying, just curious if something like this has been tested already. I’m in the process of building this set up now, and if it’s already proven non viable then I’ll go back to the drawing board
it doesn’t matter how far apart you move the pulleys, the angle to the far one
will be shallower than the angle to the near one, so with the same tension, the
horizontal component of the line to the far pulley will be larger than the
horizontal component of the line to the near pulley, so it will pull you away
from the corner, not towards it.

I believe that it has, but I can’t point to the test.
This is a very common suggestion.
