    Re: Yet another router table :)

    It's going to be incredibly slow with 5mm pitch ballscrews.

    Re: Yet another DIY CNC From Car Parts

    Depends on the software.

    I've seen one machine do something similar, and it used a mechanical linkage to lock the movement between the two, so that moving the spindle would move the table.

    Re: autotoolzero

    Try jogging close to the plate, then zeroing the Z axis, then running the auto zero.

    It's bad code, that could move up or down, depending on the Z axis coordinate.

    Re: Spindle rpm 8000-24000?

    They have very little torque at low rpm's, and if you stall them, they will burn up almost instantly.

    You're not. That's not what they are made for.

    The ESS has three "parallel" ports. You just need a DB25 to IDC26 adapter.

    Re: Soliciting advice for unusual build

    Speed vs cost.
    Unfortunately, speed costs money, so the faster you want to go, the more it will typically cost.

    Gecko is the one that came up with that "rule". Mainly to prevent excessive motor heating.

    Re: Vacuum seal gasketting

    I agree with Marv, but I'd use something a little thicker than laminate, as it will usually seal better.
    One big zone and cover the unused part of the table, rather than separate zones.

    Re: Vacuum seal gasketting

    He's got an MDF spoilboard with a multiple zone plenum underneath it, with each zone having it's own seals/gaskets. When he turns the zones off, there's no vacuum to compress the seals in those zones.
