• 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

Therefore, the difference in 128th and 64th microstepping is increased resolution and smoothness for 128th microstepping, at the cost of decreased holding torque.

• Can you tell me what gauge wire is needed for limits switches and the spindle?

The hookup wires you will need is 22 to 24 AWG stranded and shielded for the wiring of the limit switches and E_Stop. Our kit customers select various places for these switches, so we don't supply the wiring. If you don't use shielded cable, you will need to change the debounce setting in Mach3 (if that is the control program you are using).

We typically use 14 AWG stranded wire for the VFD to Spindle (U, V, W) connections.

• With a 1/2 lead screw what is the optimal steps for the stepper motor driver 1/16, 1/8, 1/4 etc

We typically use a 1/4 microstepping for lead screws, but you want to determine the microstepping only after you determine what resolution you want on that axis of the machine.

The formula:
Resolution is steps per inch or steps per milimeter

I will go over this using steps/inch:
steps = motor steps x driver microstepping
inch = the amount of travel with one full stepper motor rotation

In the case of our 1/2" 5 start 10 TPI lead screw, the axis will travel .5 inches with one stepper motor rotation.

Let's use 1/4 microstepping (4 microsteps for each stepper motor step)

Therefore:
(200 steps x 4) / .5 inches =
800 steps / .5 inches =
1600 steps/inch

Now let's use 1/2 microstepping (2 mistrosteps)

(200 steps x 2) / .5 inches =
400 steps / .5 inches =
800 steps/inch

Remember that increasing microsteps, the torque is also reduced, but the smoothness from the motor is increased.

• What are the fault conditions of the DM556 and DM542 drivers?

There are three main LED fault signals that the DM556 and DM442 drivers exhibit. There is a red and green LED. The red LED will show the fault signals.

The fault signals are:

- Over-Current: If there is continuous current that is above 16 amps, the Red LED will flash every three seconds. Over-current could be related to: a short in the motor coils, or two of the wires of the motor are shorted; of the motor wires/coil is shorted to ground.

- Over-voltage: If the power supply output to the driver exceeds a voltage of 52 volts, the red LED will flash twice every three seconds.

- Phase Error: Is the motor wires are not connect, or they are connected incorrectly, the red LED will flash four times every three seconds.

• What is the difference between a NEMA 23 and NEMA 24 motor? can I use either one on a machine?

The frame size difference of the NEMA 23 and 24 is very slight and, depending on the motor mount both will most likely fit. The bigger difference between these stepping motors is the torque. Make sure that the motor that you purchase has the appropriate torque for the axis that it will move.

Is is safe to go with the higher torque? Or if the torque is too high for what i need is that bad?

You can use a motor with higher torque. Just make sure to select the correct driver for that motor.

The frame size has nothing to do with torque. Nema 23 means a 2.3" frame. Nema 24 means a 2.4" frame. That's all. Either could have more or less torque depending on speed and power.

• What is the relay coil on the USB motion card for?

A 24V connection to the USB motion card is only needed if you are using limit switches (inputs), powering the spindle/VFD speed and direction, and for the outputs, for powering other devices (mist, coolant, etc.).

If you are using a VFD (Variable Frequency Drive, also called Inverter) for a spindle, they typically have a 24V out terminal that can be used with our USB motion card. If you are not using a spindle/VFD (we highly recommend one), then you will need to purchase a 24v power supply to power that side of the board.

The outputs mentioned above are to connect to external devices and will require a relay (a mechanical switch that is controlled by a digital signal). This mechanical switch can turn on a device like coolant and mist, or even a router, if you are using one. A relay is required to turn on these devices because the devices are typically higher voltage, like mains (110v or 220v). So, a relay can turn on or off a high voltage device with a lower voltage (24v) signal.

• My Nema 24 motors make high pitched alarm sound when changing directions quickly - what could be the cause? Red LED is lit on Microstep Driver CW230 but everything seems to run fine - is this a problem?

Stepper motors are known to make different type of noises when in motion. So there should be no issues in regards to accuracy with the steppers. You also might be able to lower the noise that comes from the motors, by adjusting the acceleration and velocity of the motors. This usually tends to either make different noises or lowers the pitch of the noises.

Cool video(personal opinion, does not relate to BYCNC):

• What are the EN connections used for on the QJ8060 motor driver? I notice that your video seems to leave them unconnected.

The EN terminal on the QJ8060 driver and all of our other stepping motor drivers is the enable terminal. We don't use this terminal and the driver will function properly if left unconnected.
