### Question #: 3511

Question: I am using your 425 Oz motors

Current Solution

The ports and pins are designated by the breakout board that you have, Now here are the schematics for both(https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/ and https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/) Which for the Parallel the pins will be 1,14,2,3,4,5,6,7,8,9. For 1,14 you will need to use them together for a additional axis. Setup will be (ex.mach3) step in (2) / direction pin (3). continued for other pins, 4,5 6,7 etc.
Now for the USB it has the label on the board right next to the terminal blocks, x-axis/etc.

• I am asking what to set my steps per using your kit stepper motors and a 1/2"x13 lead screw with Mach3

Here is the formula for steps/inch (steps per inch)

Steps = how many steps for a full ration of the motor = standard motor steps x number of microsteps for each step
Standard motor steps for our stepping motors is 200 steps per revolution.
Microsteps are selected on the driver and are shown as full, 1/2, 1/4, 1/8, 1/16, 1/32 etc... Use the denominator for the number of microsteps per step.

Inches = how far the travel is for one full rotation of the motor. For the 1/2" - 13 TPI (threads per inch), the travel length will be 1"/13 or .076923". So, for one revolution of the motor, the travel distance will be .076923 inches.

So, the steps = 200 * microsteps, let's make this 1/4 just for the formula.
The inches will be .076923. Plug those into the formula:
Steps / inch = (200 * 4) / .076923 This can also be written as:
200 * 4 / (1 / 13) = 10,400

• I'm building my own machine using your motors and drivers. What is the best dip switch settings for the 3.0 amp drivers powering the 425 oz motors

The settings that you will use for your 3.0 amp driver to properly power and turn your 425 oz-in stepper motor will cheifly depend on your application and the mechanical parts you are using on your machine. In all circumstances, the amp setting for the stepper motor (according to the datasheet) should be 2.8 amps. Use the closest setting on the driver without going over.

Here is a good rule of thumb for the microstepping which will correspond to the resolution, but wil also affect torque. You always want to try to achieve the best torque and resolution for the axis you are moving but go with the lowest microstepping possible. In cases where there is mechanical advantage, like a lead screw scenario, where for each motor revolution, the axis move a very small amount, you will want a very low microstep value. This is because the mechanical configuration will provide most of the finer resolution and you will not need the microstepping to assist in this. Increase the microstepping only in conditions where the axis is not moving smooth enough, or where there is a mechanical disadvantage. A mechanical disadvantage would be where the stepper motor is causing a great amount of movement in the axis and the resolutions suffers from this condition. Increase the microstep value up to your desired resolution, but don't go over since the torque of the motor will decrease.

• Can I drive my X axes with 2 motors using one motor driver?

It is not recommended to drive two stepping (stepper) motors with a single driver. The driver will need to output the sum of the current that is rated for both motors. The best way to drive two motors on the same axis, or if you need the motors to spin in a synchronous fashion, then have each motor connected to their own driver and connect the signal wires from the drivers to the same signal step and direction pin on the breakout/interface board.

• I have your nema 24 motors using the 36v power supply. Should I use the Bipolar series for the wiring the motors since I am using the 36 volt ad not a 24v power supply?

When connecting our power supply, no matter if it is 24 or 36 volts with our drivers/motors, you should always use bipolar parallel. This will allow you to have the best torque at higher speeds.

• I am interested in your Black Toe (24" X 48") machine, and am wondering if using two medium motors on the "X" and "Y" axis makes sense relative to power and alignment (racking). What would you recommend?

it is possible to install 2 motors on a single axis but you will require another driver and motor, but wire it directly to the same pins on your breakout board. Also the orientation of your motor since it is opposite side of the original so getting it to move accordingly to the original motor it will need to be orientated correctly. The slight shift could be the cause of the rod not being completely flat where the set screws are suppose to tighten the sprocket to the rod, so sanding it to a flatter surface might fix the shift in directions.
Currently do not have a kit or schematic available.

• How do I wire to nema 23 motors parallel

Wiring two motors in parallel is pretty easy.

Here are the steps:
- You need to have two stepper motors and two stepper motor drivers.
- Each stepper motor will be connected to its own stepper motor driver.
- Both stepper motor drivers are connected to the same CP and CW pins on the interface so the same signal is delivered to both drivers.

• How do I put two motors on the same axis

Yes, you can use 2 motors in the same axis output, however you will still need a driver for that stepper motor. Also depending on the orientation on which you mount the motor you might have to invert the direction of the motor, and that will be simple by swapping the A+,A-, to the B+,B- locations and vice versa, from the driver to the motor wiring.

The wiring scheme would look like this:
The step and direction output terminals on the CNC controller interface for the axis you want to have two motors would connect to both drivers of the two stepper motors on that axis.

I have been running two motors from the same driver for 10 years on my 3m x 1.6m router. Both motors driving the gantry are wired together. I see no reason to use two drivers. The motors are high torque Nema 34. I've had no issues.

• [672] can this drive your 425 oz-in motor?

Yes, this driver will be able to spin this motor, but you will not be able to take advantage of the full torque of the motor since this driver has a top amp setting of 2.5 amps.

• How can I have two stepper motors on one axis

Yes, you can use 2 motors in the same axis output, however you will still need a driver for that motor! Also depending on the orientation on which you mount the motor you might have to invert the direction of the motor, and that will be simple by swapping the A+,A-, to the B+,B- locations and vice versa, from the driver to the motor wiring.

Also you can run a slave motor using another axis on the board, and setting it up in the Planet-CNC settings.

Planet-CNC/File/Settings/Axes, here you will enter 3 in the Number of Axes location, and then change the Function of the Axis 4 to Slave 1. There you will have the 4th axis or A-axis be a slave for the x-axis.
Slave 1 - X-Axis
Slave 2 - Y-Axis
Slave 3 - A-Axis
Slave 4 - B-Axis
Etc...

• MY MOTORS ARE RUNNING VERY HOT.

If your motors are hot to the touch, this is normal. Current is being drawn by the motor coils as the motor moves and as the motor stays at a position. If the motor is not using the current in the coils to move (holding it's position), the energy will be translated as heat (rather than motion, sound or light). Even while moving, some of the energy will be lost as heat. Remember that energy cannot be created nor destroyed.
