hi all
been reading this forum now for a while, picking things up from you guys and i am now ready to start my build which will be a wood router , i have ordered from zapp 3 nema 24 3nm steppers, 2 1200mm long fully supported 16mm round rail 4 open bearings . going to use 12mm trapeziod 3mm pitch for drive , i have a block of derlin from ebay to make nuts , and have made a tap from a piece of trapeziod, slowly gathering parts together, would 2.5 amp drivers be enough or do i need 4 amp, the attachment is a section through the x axis would this work , i would like to make the y axis stiff enough so as to drive the x axis from one side only , any help would be appreciated
