I am planning to make a cnc using arduino uno board but now I am in a situation to select the motor for my drives. As it seems that the stepper motor(Nema 23) is only giving about 300rpm which may leads to low speed for leadscrew carriage/ tool movement and I would like to et about 1000 rpm for motor
So can use some geared dc motor with some feed-back to get the result ?
some times I also seen that the stepper motor is skipping steps from arduino uno at higher speed 300 rpm!
expecting helps from you..!!! :disappointed_relieved:
Perhaps some more homework is needed.
You need to have an acceleration period for what ever you are moving using the stepper motor. How much mass does it have? Then are you needing to decelerate and stop the device, then hold it in position? How accurately does it need to be held? Is you device another motor that will try to move itself?
Your lead screw will need to be lubricated if it is to have much lifetime. Will your project create dust or abrasive particles? You may need to have shields on the lead screws.
