  • ART uses high quality Brushless Servo Motors for positioning on all axes of it's CNC Plasma and Router Machines. See the huge differences in performance between the latest technology Brushless Servo Drives when compared to old school stepper motors.

    hello dear
    i have sanyo denki dc servo motor i wanna be conction with mach 3 can you help me

    Hi Keith, the cost is much higher for servo motors. That is why most hobby and diy machines only use steppers. For a serious production machine though you cannot go past servo motors for performance. When your business revolves around production speed then you cannot afford to skimp on a stripper motor machine. All ART CNC machines use servo motors on all axes.

      +ART CNC MACHINES Thanks ART I agree 100%. I did some research after watching your video. I saw a few examples of stepper crashes on the web, not pretty. It usually fries the steppers or mill head motors as well. As a hobbyist I'll have to keep a close eye on mine when I get it set up. I'll probably take ipadize's advice and use a encoder and look into putting a current watchdog on it linked to a emergency stop input on the "Controller/Breakout board". If I can't afford the best at least I can incorporate some equipment safety measures. Thanks for the video it was quite informative. Best Wishes n Blessings Keith

    Can someone to recommend me a cutter plotter, not very expensive, with servo motor? Thanks a lot!

    closed loop stepper ;)

    What is the cost comparison of each. I can get 3 NEMA 23'S 425oz motors, 3 DQ542 4.2 amp 50v Controllers, a 350W 36v Power Supply and a 5 axis Breakout board on eBay for $265.00. What does comparable system cost? Thanks Best Wishes n Blessings Keith

    Stepper motors are very effective in CNC machines but encoders have nothing to do with it. If you're relying on an encoder on a stepper motor to improve performance in a CNC, you're doing it wrong. The only thing you would use the encoder for would be to tell you something is damaged / you lost position.

    Crusty vintage video... but informative none the less.

    All I know is how basically all high quality plotters and CNC machines, such as HAAS units, have all made the switch to servo systems. A "fixed step resolution" within a stepper motor also indicated the fact your dealing with resolution permanence that you can't refine past what the motor allows in physical build. That being said, I have noticed small jagged lines around curves during XY axis coordination that pretty much tells me there is a significant precision loss compared to a servo controlled machine.

      bullshit. ever heard of gears? put 1:5 reduction gear on each stepper and voila. not to mention higher ratios.

    Stepper motors are nowhere near as effective as servos! Sure, the encoder feedback will let you know where you are/are not but how do you propose to maintain commanded velocity/position without a PID loop?
