I have started our project to build ( huge) 3d printer
We chose RA controller to control huge size of printer
With dimensions 50*50*50 cm for object(model) that we will print it
I'm the one who have to chose the stepper motor
But unfortunately I'm do not know how to chose a stepper motor
I build reprap printer with NEMA 17 motor ( which is came with the kit )
But when i search for motors i found a lot of models with deferent specification and deferent type some of them comes with gear and some without
The situation here is i want to buy motors for x,y and z axis ( with its gears)
Which can hold the heavyweights of models with volume 50*50 50 cm
And has the ability to move the plate without any problem
This the RA controller details
