Just got a quote from Ulrich for $80 for the extrusion. I called around a few places and it looks like $50 if I want normal anodizing (12 micron) or between $150 and $300 if I want the parts hard anodized (25-100 micron, depending on supplier).

So yeah, any idea which type you’ve got? The regular anodizing keeps the cost much more reasonable, but it’s a false economy if it ends up giving the rails a limited lifespan. The hard anodizing is probably what I’d go for with no further information given that I want to be able to load the machine up a bit, if possible, but at $250 for the rails that’s heading rapidly towards the cost of a set of linear rails for a gantry type system…
