Spectra line modification.

If fishing line had never been discovered as an alternate method of power transmission, I would think GT2 timing belts were where it's at. However, we know from thousands of printers out in the field that fishing line is the better choice for two reasons: cost (it's exponentially cheaper) and parasitic inertia (it weighs less.) The drawback is R&D. After that hurdle, what's left to do is spend less money and have your steppers do less work to achieve the same result. What's not to like?

I tried making a few parts to do this conversion, but my CAD skills are seriously lacking. If I could figure out how to make something like polygonhell has in that video I posted earlier then this would be really easy with our printer, given that it has the spots to put the extra pulley.

Any interest in these:

I have to wonder if the bearing flange (thing:91510) would work on the Rostock Max idler because there is very little space between the bearing and idler sides.
Has anyone tried this on the Rostock Max?

yeah, i got the "all metal, sharp-tooth drive gears" which also makes replacing the belts more expensive because I'd probably end up getting new pulleys also

If your sharp pulleys are chewing your belts, I bet SMC would send you new pulleys at no cost - just email them.
