Again, I already mentioned the bending, and that the rails can be fully supported which prevents that. My point was just that there are plenty of printers that get good results with rods. You can't say "we all upgrade to linear rails", we don't all do that because cost is a concern, and there are a lot of other ways to get rid of z wobble. Plus, the OP is building a delta with belts so the the z wobble you get from a bent screw is irrelevant.

As for crunchy bearings, it wont influence your print unless it takes you a cheater bar to turn the bearing. Cleaning and re-oiling the bearings will make them run a bit smoother if really bothers you, but your printer wont care. If you're worried about belt stretch you should go for steel core belts not name brand aramid or glass fibre ones. In that case even the cheapest Chinese belt that might skimp on the reinforcement will do fine. For such a big delta with long belts steel core might be well worth considering, just make sure you pick the right pulleys and idlers so you don't end up with broken reinforcement in a few weeks.Last edited by Trakyan; 09-26-2019 at 04:03 PM.
