    I did not follow the advise to plan before buying!!! I have a set of ball screws & nuts 1605's. 300mm, 1000mm & 1300mm long. I bought these off aliexpress, when on offer. With how things have panned out they are surplus to requirements, still in the packaging, I only opened them to check they were as they should be.

    i am after 80 for them shipped to your door. I paid slightly more but got stung for customs as well.

    i also have a number of other bits, off a machine I am refurbishing, with guidance from Dean. I am basically replacing the controllers and motor drivers, I have 3 gecko G201x drivers and some cnc4you controllers if anyone's interested to.

    I think the answer was here

    It means the screws are 16mm with 5mm pitch with the lengths as stated. When they say machined at one end it means that they have been machine to accept the bearing (usually an AC type bearing) and the bit to put the drive pulley or coupling on.The other end of the screw is generally machined to accept a standard bearing .

ID:	19372Yes I still have the boards, see pics attached. Price say - 50% of price new including postage, so 16 for the cnc4you one, and 5 for the mach3 interface board. PM me details if interested.

    The ballscrews are machined for fixed free configuration, ie for bk12 and bf12.
