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.
