Hello everyone, as per question. Do I need to use them? My machine will need leadscrews of dimensions 1500mm x 1000mm x 500mm. I would want to save money as much as I can, so if there's not a need for me to have multi start, then I wouldn't want to get it.
Also, I prefer metric measurements and realise that its hard to find metric ACME screws, so I turned to trapezoidal screws. Is this a good choice? Thanks guys!
