    hi
    Sorry my english is not so good

    my question is it possible to use a 12mm acme lead screw in c-beam
    because the 8mm 1m long are very soft i think
    one of mine already bent a bit

    thx for support

    It is possible, but you'll have to make custom end mount

    Lower cost.

    The main issue is verifying that you can mount the lead nut to the plate and have the mounted assembly fit into the limited amount of space inside the track. You will need to custom machine some of the parts to achieve this. DumpsterCNC is a good source of information on the potential size of the fittings.

    Ok thx
    I think the 250mm and 500mm 8mm acme is good
    But the 8mm x 1000mm acme is to soft
    So I want to check the 12mm
