    The e3d motion system was good inspiration for me to build a high end printer myself. I absolutely love the performance I'm getting. 250mm/s on a direct drive titan aero. That said I'm know there are improvements that can be made, and I'm already planning my next build. Going to try and modify the e3d tool changer system to be double sided and hold 10 tools on the next one.

    iirc I read/watched somewhere that the e3d motion system used blocks with preload on some of the linear rails. I was curious which axises, and how much preload you found to be best.

    Has there been much experimentation with wider belts and or bigger steppers? How did they affect performance, ringing ghosting, etc?

    The parts lists are in GitHub:
    https://github.com/e3donline/Motion-System/tree/master/PDFs

    The Z axis (https://github.com/e3donline/Motion-System/blob/master/PDFs/MS-Z-AS v1.5.pdf) uses a Hiwin MGW12H-Z1-H-M. (Light preload, high accuracy, stainless steel)

    The Y axis (https://github.com/e3donline/Motion-System/blob/master/PDFs/MS-Y-AS v1.5.pdf) uses a Hiwin MGN12H-Z0-H-M. (Very light preload, high accuracy, stainless steel)

    The X axis (https://github.com/e3donline/Motion-System/blob/master/PDFs/MS-X-AS v1.1.pdf) uses a Hiwin MGN09-Z1-H-M. (Light preload, high accuracy, stainless steel)

    Hiwin MG* datasheet:

    (Accuracy classes on page #4, preload on page #5)

    Thanks for that! Guess I have 3 blocks to upgrade.
