The prime tower is sometimes useful. I do not usually use it with PLA. Sometimes will with nylon.
That the prime tower broke may indicate that your layer bonding is low...possibly printing too cold.
try some with and without and see if you find enough difference.

The first is typical if a section breaks away. All further layers printed over that area are printing on air, producing spaghetti or birds nests...
the second looks about normal for PVA.

Does it make sense to build woth a prime tower ? Maybe I can make it larger in diameter so that it doesnt break. Im wondering if the "wasted" material is worth it in terms of print results.
