I set up the rest of the machine as any other hobby cnc routers with stepper motors driving the axes and limit switches attached as the hard stops. Everything works great .
The nature of a stepper motor doesn't lend itself to use as a spindle motor since it by definition moves forward in discreet steps rather than in a smooth motion. Also the torque output decreases rapidly with speed so that by the time a stepper is turning 600 rpm, the best of its torque curve is behind it. [lwptoc hierarchical="1" numeration="none"] Whatever your motion control applications, choosing a suitable motor is essential for its efficiency and productivity. It can be challenging to pick between stepper and servo motors since several factors come into play: among the most important are speed control, positional accuracy, and being cost-effective. .They are actually far more accurate than steppers but many won’t have a machine that will take advantage of the micron level positioning that very high end 6+ figure industrial cnc machines are capable of. None of those machines use stepper motors. From Geckodrive.

All of the motors would need to be at full torque to reach the 9 amps (3x3). This depends on the mechanical method you are using for each motor, and how you are using the machine. In most cases, only two motors are moving at a time (i.e. 3D carving where the X and Z are moving simultaneously and the y only moves to go to the next row).Another consideration is that larger motors typically need higher voltages to work optimally. It's not unusual to see 36V or 48V on small to medium CNC machines because the higher volltage is required to overcome the motor coil inductance.This CNC machine is powered by using two stepper motors and one servo motor. That is, it acts across the X, Y, and Z axes. Also, all of these motors are activated using the L293D motor drive shield and Arduino UNO board. If we want to draw a character through this CNC machine, its G-code must be obtained. The Inkscape software has been used for .If you use one, you either need to drive it from the center like a 3d Printer (impractical on a CNC) or have a belt system so that one Stepper can drive both sides at the same time. If you only have one stepper and are only driving one side of the Y, then it would be easy for it to twist, especially in motion transitions.
