Hi all,
i am just about to start to build my own CNC router and i am looking to make it to cut 8ft x 4ft aluminium composite panels (not that hard to cut)
i am making the machine from aluminium extrusion and its going to have 3 axis using 25mm x 3mm pitch threaded bar for all 3...which i allready have all machined to the right size.
i am going to use one 25mm threaded leadscrew in the middle for the x axis.
i have the full idea for the machine but the only thing i have not yet purchased is the stepper motors and the controller/drivers to run the machine....can anyone suggest what motors would be best for this size of machine anbd the size of leadscrews i am using?
does anyone know of a complete kit i could buy that would be suitable for this?
i am not really bothered about the machine being really fast or anything just want it the cut/engrave the soft aluminium panels without any problems. (maybe using mach3 software)
i have heard allot about the nema 23 and 34 motors but not sure if these would be suitable ...can anyone help? or does anyone know where i can buy the full kit?
thanks very much,
Gaz
