increasing the torque of the stepper motors can they run faster without missing steps? i need speed up my cnc router, i have 1200 oz on the Y, 640 on the X and 264 oz on Z, i am planing to change the 1200 oz motor to the X axis and the 640 oz to the Z axis then get two newones of 2550oz-in for the Y axis, will this help to increase speed and keep on track without missing steps?
