In all CNC electronics configurations, you will need the motor paired with its own driver.

If two motors/drivers are intended for a single axis and the motors need to turn at the same rate and in the same direction, then the two drivers for these motors should be connected to the same signal wires from the breakout board (step (CP) and direction (CW)) signal wires.

If the motors need to turn in opposite directions, then either one driver will need to have the direction signal inverted, or resolve the opposite direction through a change in the mechanical drive train (i.e. flip the rack on a rack and pinion configuration, or in a roller chain setup, have the chain ride along the opposite side of the drive sprocket).

How do I go about purchasing a redleaf system with 4 drivers, where the (y) and (a) driver are connected to the same signal from the breakout board? I'd also need them to rotate in opposite directions.

The redLeaf webpage contains a purchase option for an extra motor and driver. We can setup the redLeaf system uniquely so it conforms to your application (i.e. motors running in opposite directions).

I've built a machine where the y axis has (2) 425oz motors, x axis has (1) 425oz. motor, and the z axis also has (1) 425oz motor. Would it be better to purchase a redleaf system with 4 drivers? or can I just connect both y axis motors to the same driver for a total of 3 drivers?

Fusion 360 is a program that allows you to design in a parametric 3 dimensional environment and also provides a great CAM toolset. Fusion 360 will produce the gcode with the CAM capabilities. The gcode is used to move the machine in various ways in order to mill the material; however, software is needed to interpret this gcode and cause the machine to move according to the gcode instructions. This is called control software. So Fusion is CAD/CAM, and you still need "control". Mach3 is one example of control software for milling and is highly recommended.

Install Mach3 onto the computer that will connect to the redFly(CNC electronics), then configure the Mach3 parameters for the machine (motor tuning, plug-ins, inputs/output, etc.). Home the machine, load the gcode into Mach3 and the machine will move according to the gcode.

A word of caution, since you are new to CNC machines, make sure you familiar yourself with the machine and the movements of the machine specific to how the gcode is arranged with respect to the coordinates of the machine. Try with very simple gcode until you get a very good understanding of how the machine will move.

Hello, My friend has purchased the Redfly and I am helping him a little with it. We are both very new to CNC. I am using fusion 360 at the moment. This can tool path and create gcode. I was wondering if Mach 3 or similar is still needed. Is there a tutorial you could point me to that explains how to get the Gcode from the PC, via Serial to the Redfly?

When wiring the limit switches to our BoB(breakout board), depending in the older model or our revised version (https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/0/), the older version will need the COM (limit switch) connected to 5V and the NO/NC to your input pin, but with our newer version you will use GND(ground instead of 5V) to common and the same for NO/NC but the setup in the mach3/confi/ports&pins/ is still the same.

Here is a tutorial where you can see how to set up the limit switches correctly (with our older parallel BoB): Part 1:(

I am attempting to set up limit switches on the 5 axis parallel breakout board that came with my BlackFoot kit. The output pins are driving the motors perfectly, but I can't figure out the input pins. With one lead in the 5V pin and one lead testing the input pins, my multimeter reads 0V for all of the input pins. Shouldn't those circuits be +5V? Where am I going wrong?

if you purchased the USB interface, you will need planet-cnc software rather than Mach3, and you will need a usb cable to connect the usb interface to the computer.

The blackToe 2x4 CNC Machine Kit with optional table will need wire to connect the electronics. Don't forget to get some end mills to use for cutting the intended material.

I would like to design my own CNC router around one of your electronics bundles, either the 3 Axis - Heavy Gantry or 3 Axis - All Large Motors. Do you have the data sheets for the motors so that I can use the dimensions in my model?

Here is how to connect your router to the parallel breakout board through the on-board relay. You will need a spare extension cord. You will need to remove a portion of the outer jacket of the extension cord to expose the white, black and green wires (white = neutral, black = live and green = ground), understanding that the neutral and live create the completed circuit.

See this image of a similar connection. The terminal has the same connections.
https://www.buildyourcnc.com/images/vacuum-pressure-controller-relay-terminals-700.JPG

Image of the relay terminal:
https://www.buildyourcnc.com/images/breakoutboardrelayNONC.PNG

The live/black wire would be cut and one end of the cut would be secured into the P terminal and the other cut end would be secured into the S terminal. The live and ground wire would be uncut and travel from the plug to the router.


Additional Information:
You can also connect other high powered devices to the breakout board using any of the output terminals. You will need to supply extra relays like the one shown here:
https://www.buildyourcnc.com/item/electronicsAndMotors-breakout-Relays-relay-board-250V-12A-5V

Or you can find SSRs (Solid State Relays) that will accept 5v to drive the relay coil. Make sure the SSR will protect the 5V line from Back EMF as there is a coil in the relay. The one we sell contains a fly-back diode to protect the 5v terminal.

I have your breakout board with relay parallel port , I have a vacuum, light on router and air pump I want to also hook up to board, can I hook those up to board and also could I had reylays to each one, what is the best way to figure this out any information would be great. Thanks

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.

I HAVE FOLLOWED ALL THE "CNC ELECTRONICS 1 - 9" VIDEOS AND I'M USING ALMOST EXACT SAME COMPONENTS (MOTORS RUN SOUND GOOD) BUT MOTORS ARE RUNING VERY HOT IN JUST 15MIN WITH NO LOAD DONE SOMETHING WRONG OR DO STEPPERS HOT?

Consider the loads on each axis when choosing appropriate stepper motors. If your holding torque is maxed out at roughly 16oz/in (1lb/in), then you could use the NEMA 11 or 14. Also consider the shaft sizes and current ratings when choosing drivers that pair with the motors.

My plasmacam cnc machine has servo motors with an optical encoder to provide position sensing. Can the pokeys57 cnc controller and drivers run those servos?

All of our controller will allow two steppers on any of the axes. Multiple stepper motors and drivers on a single axis is more a function of the way the stepper motor drives are connected to the output pins of the controller. To connect two stepper drivers to a single axis, you need to connect the output pins (dir and step) to each of the two stepper motor drivers.

Consider the controller on cost, features and how they are connected to the computer.

Out lowest cost controllers are:

Mach3 USB board - Has good features and uses the USB from the computer as the main connection
https://buildyourcnc.com/item/electronicsAndMotors-electronic-component-breakout-Mach3-USB-Board

Parallel Breakout - The computer generates the main signals and this board conditions the signals for the drivers. Although it requires the parallel port from older computer, the board has the most broad compatibility with control software out there including Mach3 and LinuxCNC.

Highest cost but most feature rich:
