If you use parentheses around a repeated group in XBetza, without indicating with a following digit how many repeats you maximally want, it uses the maximum board dimension as a wild guess. For the Hexmaster the repeated group describes 3 steps rather than one. So even on a board of size 10 repeating it 3 times already spans the full board. When there are additional steps outside of the parentheses, you probably only need two repeats.
So you could just insert a 2 behind the closing parenthesis, to suppress all the longer repeats that would never fit the board anyway.
