    I am designing a 3 axis gantry to measure magnets and magnet arrays, up to 600mm x 200mm x 30mm.
    I need to keep everything within about 150mm to the magnets non magnetic to not affect the fields. Does anyone know if the lead screws 300 series?. I may go with aluminum shafts from McMaster and plastic sleeve bearings for my Z axis, the rest can be V-groove.
    Thanks

    Not quite a complete question. Please restate.

    Hello Thoreauman,

    I don't know non-ferrous Acme screws but the M5 screws and nuts are sold made out aluminium; you can find them in the RC and bicycle world.

    Replying to Rick 2.0, is the openbuild 8mm acme lead screw made from non-magnetic 300 series stainless steel? Thanks. I am curious if anyone has worked on something similar, measuring magnet fields.

    Yes it is, the Acme screw is almost non-magnetic. I'm helping out on a military project with V-Slot and they also use it to mount a scanner to the structure.

    Almost being the key word there. I have no idea what it is made from but was able to note a slight attraction to a fairly strong welding magnet.

    Are belts an option?

    I think I will try the lead screw and use belts as a fall back. I will have a long plastic end for the probe. I am using belts for the X and Y. When I have it modeled up I will post it.
    Thanks for the help.
