I have contemplated building one with a base/frame made of scrap granite countertop material, granite surface plates, or an epoxy/mineral casting. Vibration dampening is a good thing. The high accelerations of marginally rigid frames can induce visible artifacts.
We have an fdm printer kit we designed and have freshman engineering students build. These print better parts when sitting on a large, solid workbench than they do on a lightweight table. Instead of T-slot aluminum, these use heavy gage stainless steel fabricated for us by a local food equipment manufacturer. -- Ralph On Jun 4, 2020 12:04 AM, Bari <bari00...@gmail.com> wrote: CAUTION: This email originated from outside the Walla Walla University email system.

Any idea of cost or if anyone makes this? _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://nam05.safelinks.protection.outlook.com/?url=https%3A%2F%2Flists.sourceforge.net%2Flists%2Flistinfo%2Femc-users&data=02%7C01%7Cralph.stirling%40wallawalla.edu%7Cf44ac78ec5564af6519608d808558064%7Cd958f048e43142779c8debfb75e7aa64%7C0%7C0%7C637268510608718146&sdata=4pItnNUmFn3fFyEFSq%2BOLjAqbYnRFBO%2FZPsHwZOGuVE%3D&reserved=0 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
