What's the difference between 128 microstepping and 1-1/64 microstepping?
I'm not sure what particular devices you're talking about so I can't help you as far as compatibility goes, but a microstep fraction refers to the resolution of the rotating motor. let's say your motor takes 200 whole steps to make one complete revolution of the spindle. If you then set your motor to run at 1/64 microsteps it would mean your motor is taking 64 times more steps to cover the same distance, making a total of 12,800 steps to make one complete revolution of the spindle. So a smaller fraction of steps like 1/128, would take even more steps to complete one revolution, 25,600 in fact. If you're talking about motor drivers it's probably telling you how many options of resolution you have. one giving the highest resolution of 1/128 microsteps but probably still capable of doing 1/64, 1/32, 1/16, 1/8, 1/4, 1/2 and 1 whole step. the other one that says 1-1/64 is telling you it ranges between 1 whole step and 1/64th microsteps, so you could do the fractions between like 1/32, 1/16, 1/8, 1/4 and 1/2 as well. The amount of microsteps you want to make in one revolution is totally up to you, more steps potentially means a more precise machine, but at a certain point the extra steps may be unnecessary. hope this helps

what is microstepping concerning the drivers
Stepper motors are designed to move in specific increments; these increments are called "steps". For example, a common standard is for 200 steps per full revolution. Microstepping is a method to send signals to the motor to move only a fraction of a full step at a time. For example, if a motor has 200 steps per revolution and is microstepped 1/16, then effectively there are 3200 small step movements (microsteps) per revolution instead of 200 larger ones. This makes the motion of the motor much smoother and more precisely controllable, at the cost of decreased holding torque. Here are is a good references for stepper motor theory: http://users.ece.utexas.edu/~valvano/Datasheets/StepperMicrostep.pdf And Wikipedia has a good overview as well: https://en.wikipedia.org/wiki/Stepper_motor Additional Information: Additional Information: Therefore, the difference in 128th and 64th microstepping is increased resolution and smoothness for 128th microstepping, at the cost of decreased holding torque.

For a school project we are replacing/fixing the hardware/software of a paper cutting table. The blades that are used will need tangential controls. Will Mach3 and/or Mach4 support this tangential manipulation? Our table will be uses a stepper motor for the tangential control (blade orientation through curves).
When using your tangential component, Mach 3/4 will be able to function with that component. We have a couple of forums post that we refer to, that go into greater detail on using the tangential components.
