  • I built a 2' x 4' cnc about 2 years ago and bought all the plans and part through this website. My average 2D design takes approximately 35-40 minutes to complete. Is there a way to make my cnc faster?

    Yes, if you are using 1/2" standard allthread lead screw coupled to your stepping motors, you can increase the speed by changing the lead screw to 10 TPI 5 Start Lead Screws with antibacklash nuts. This will allow you to have up to 200-300 IPM (inches per minute) travel and cutting speeds. The reason why the feedrate and jogging speed is faster is because the lead screw will travel a farther distance for each turn of the motor. A standard allthread will only travel one inch after 13 turns of the motor. The above (link below) 5 start 1/2" lead screws will travel one inch with only 2 turns of the motor! That is a drastic difference and you will get more torque from your motor since most of the torque is present at low speeds.
