after under-building with some too lightweight Gt2 2mm pulleys and belts, I’m ready to get a HTD 5M setup like everybody else. I found some Aluminum 12T pulleys for $3 (robotdigg), but everything I’m seeing for the larger pulley is very expensive. Like $18 per pulley is about the cheapest I’ve found in aluminum (eBay) and $14 in plastic (sdpsi).
Where is a good (inexpensive) place to buy pulleys and belts? Further, what about 3d printing the large pulley with PLA or ABS? Especially with the larger pulley that is under 4 times less stress than the smaller one-- will it hold up? I’m building 2 DM boards concurrently, so that’s X4 on all these parts. I know good parts cost good money, but these drive component sellers are exorbitant to us piece-meal part buyers. They have to be making at least 20 times markup by the time they charge min order fees and shipping.
Thanks! And, much respect to the e-board specific parts sellers. I understand what a niche market you’re in and the time involved in selling to such a small demographic. If I wasn’t 280lbs and live on a hill, I might consider getting the bolt on 44T gear at diyesb for $35+shipping.
