I am building a machine that requires 2 steppers to drive the Y axis, can you make me a redleaf system using the 651oz steppers that will work for me?

Yes, to build a computer controlled table saw fence, you can try the following:

Assuming that the fence can already move, add a motor on both sides coupled to either lead screw or chain mechanics. Lead screw would be the best solution. The lead screw nuts would be mounted on the fence aligned with the motor shafts at the front and back of the fence.

I would recommend the 425 oz-in stepper motors and 3.0Amp drivers for each motor. You will need a power supply rated for 24 volts. There is no need for a higher volt power supply. Interface the drivers to the computer using a USB interface, or a parallel breakout board.

Drivers: https://buildyourcnc.com/category/driver

Measure the length of travel and get lead screw twice as long since you will need lead screw on both sides. Add a bit more length for space that will be needed for the mounting. Plan as much as you can before purchasing.

I am interested in building a computer controlled table saw fense. Do you have any products that could help me.. Thanks

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.

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

Attaching two motors in parallel is possible, but you will need another motor and driver for the opposite side. Each motor must have its own driver to work accordingly and fluently. The two can be wired together, to the same pins on your breakout board and set the dip switches on the driver to match the ones on your x-axis(ex). But remember to view the orientation of the motor and which way it spins, since it is on the opposite side it will have to be orientated correctly to move in sync with the other motor.

I just finished building my first CNC with the electronics I purchased from you and I am already thinking about improving it. I would like to build a 2 motor X axis solution. Is it possible to attach 2 parallel motors and drivers to the BlueBrew Breakout Board? If so, how?

Generally, 3D printers require the following components:

Electronics to move the motors, limit the motion and extrude the filament:
- Stepping motors, one for each axis (X, Y and Z), and one for each extruder

- Stepping motor drivers that are capable of allowing a current draw that matches the stepping motor connected to the driver. https://www.buildyourcnc.com/item/3D-Printer-Component-electronicsAndMotors-stepper-driver-2!5a-FDMElectronics-driver2!5a

- Arduino Mega 2560 to serve as the g-code interpreter. https://www.buildyourcnc.com/item/3D-Printer-Component-electronicsAndMotors-electronic-component-arduino-mega-2560-FDMElectronics

- Arduino shield that breaks out all of the connections from the arduino (3D printer main board). https://www.buildyourcnc.com/item/3D-Printer-Component-electronicsAndMotors-3d-printer-mainboard-FDMElectronics-3dprintermainboard

- Extruder to control the temperature of the hot end (receive temperature readings using a type K thermocouple and send current to the heating cartridge, or power resistor). https://www.buildyourcnc.com/item/3D-Printer-Component-electronicsAndMotors-extruder-controller-FDMElectronics

- End stops to limit the travel of each axis. https://www.buildyourcnc.com/item/3D-Printer-Component-electronicsAndMotors-electronic-component-end-stop-switch-safety-FDMElectronics-endstop

- Type K Thermocople to sense the heat at the hot end. https://www.buildyourcnc.com/item/3D-Printer-Component-typek-thermocouple-heat-sensor-newbiehack-sensors-typek-thermocouple-heat-sensor

- Extruder with motor and hot end. https://www.buildyourcnc.com/item/3D-Printer-Component-extruder

I am building a big 3d printer using 3 nema 23 and two nema11 for dual head extruder. I need a list of the rest of the stuff I would need including hardware to run these motors and the sofware I would need.

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

All you need is a CNC controller like the following options:

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

This controller is easy to connect using standard wire screw terminals and works with the mach3 control software.

https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach4-mach3-USB-ethernet-Board

This controller is a little bit more difficult to connect, but is a more feature-rich controller and will work with both mach3 and mach4 CNC control software titles.

Specifically, a CNC controller connects to the computer via a USB cable and connects to the motor drivers. These controllers also connect to the limit switches, spindle/router control, air/fluid/mist control, etc.

The cutting area is 20" x 40" for the book machine. This area is determined by the 2'x4' sheets that make up the bed of the machine. You can increase this area if you use larger sheets and adjust the gantry width by the same difference of the width of the sheets.

WE don't have an actual file that contains the instructions for the machines as they are a part of a larger database file that is queried during the product page's rendering in the browser. The best option would be to print the webpage on a printer and use that as notes.

Which 3 axis combo pack should I order to replace my millstar3 motors on my full size knee mill

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.
