    This is really awesome! I was just thinking of building the acro system, but was refraining as it doesn't have a Z axis.

    I'll be primarily using it to cut paper/cardboard with laser or a plotter cutting blade.

    Just curious, Do you think it can mill murals like these?? just works of art on foam or light wood maybe?

    Looking forward for updates!! Great job!

    Hi @yogeshnd. I don't think it will be able to do murals like that unfortunately. In foam — sure, but I don't think it could handle wood.

    I don't have any experience with milling, but I always thought there must be a reason those machines are always just much bigger and heavier than a 3d printer or a laser.

    Hi, I'm currently using one of these brushless motors

    It's good enough for drilling small holes, but not good for milling.

    Did you add a place to add an end stop for your z axis? Also how long did it take you to print out the 3d parts on your Prusa?

    Beautiful design on the Z-axis!

    I love how you have the support for the drag train on the top of the Z motor. I need to do something like this. So smart!

    I noticed that there is a threaded rod inserted in the light-blue 3d printed plastic piece on top of the Z-motor. What is this used for?

    Does the lead screw rub away the red plastic at the bottom of the Z-axis?

    Thanks,
    -Todd

    I'm not using any physical endstops, going with TMC 2130 drivers and their stallGuard feature. Speaking of printing, it took around 10 hours for the main part.

    Thanks Todd!

    That threaded rod is used as a spool pin for cotton thread. I use it when I make string art.

    Speaking of lead screw and the plastic — it doesn't rub away the plastic, the hole is larger than the lead screw. But I do think putting a bearing there would be a good idea.
