Well the cutter carriage needs to travel at 2mm min and it needs to travel smoothly i.e moving all the time, so surely you need a very fine pitch lead screw to acheive this?
I'm not 100% about this but that's the sense i make of it anyway, if thats not how it works what's the purpose of the 0.050" lead leadscrew that i saw for sale?
And i ask again can anyone give me any leads as to info on leadscrews? books, websites whatever i just need to know more before i can make informed decisions.
Many Thanks
