I think we can design some really nice mods that don’t require that much work to put on. Looks like a bolt on linear bearing solution would be the most economical way to get better performance. And yes Hiwin are nice but my prototype 600mm were a little cheaper and pretty smooth (after clean and lube)
Yeah the atc adapters aren’t rated for high rpm so it looks like an integrated spindle is the answer. Ive been talking with Datron Dann about a tq range I should be looking for. Might be able to put something together for $2000 with vfd. But…I have another idea that’s could be a little more economical.
