I would recommend using a separate 24VDC power supply for the controller. The 24VDC that is connected to the controller is used for delicate input signals and output signals that control external devices. To keep interference and possible current and voltage fluctuations at a minimum due to the motor load, a separate power supply would be best.

[575] Can the 24VDC supply used for the interface board be the same supply used for stepper drivers, or do you need separate power supplies? If not, does GND and DCM need to be isolated?

The size of the stepper motor is measured in holding torque, generally oz/in. You will determine the torque loads of your axes when selecting steppers. Once you know which stepper you need, the drivers and controller board are simple to pair with them.

I'm trying to build my CNC router 3m*1.3m, but i'm not sure what is the type of stepper motor i should pay, all my CNC body is Al. I need to bay 4 Stepper motors, 4 drivers, spindle, inverter, and i don't know what is the type of controller ?

Yes, the 651 oz/in motor requires a driver that is compatible to the motors (the motor will draw 6 amps max and the driver paired with this motor will be able to allow for a 6 amp draw). I would also recommend a 36 volt power supply for better high velocity performance.

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.

You can only use the planet-cnc interfaces with the PlanetCNC software. If you like the software and want to remain with that software, the hardware interfaces will need to be purchased from the planet-cnc folks.

I would recommend using the Pokeys57CNC interface which is compatible with Mach3 and Mach4. You can also consider the Mach3 USB interface if the Pokeys57CNc interface is out of your price range.

The overall dimensions of our 2.5 modular stepper divers is:

L: 1.875"/ 47.625mm
W: 1.433"/ 36.3982mm
H: .585"/ 14.859mm (height might change due to different terminal block height (other we have on hand is .464"/ 11.7856mm))

Currently we do not have a CAD model on hand.

We have not had any issues with stock firmware on the AWC708lite. Upgrading the firmware will be at your own risk. We can contact our supplier and see if they can provide a suggestion for updating firmware. Contact customerservice@buildyourcnc.com to inquire with a person who can help.

Here is a list of the parts needed to get the electronics combo functioning (parallel or USB interface options):

- 22 or 24 gauge stranded hookup wire to connect all of the drivers to the USB or parallel interface (terminal to terminal connections),
- 18 gauge stranded hookup wire to connect the drivers to the power supply,
- a power cable (extension cord) to connect from the power outlet to the power supply,
- 4 conductor cable to connect the drivers to the stepper motors,
- a USB cable to connect from the computer to the USB interface (or for power to the parallel interface),
- for the parallel interface, a parallel cable is needed (male to male db-25),
- a computer (for parallel interface, the computer will need a parallel port and if the computer does not contain a parallel interface, the motherboard may have a header for it, or you can purchase a parallel adapter to plug into the motherboard, very inexpensive),
- cnc control software: for the USB interface, you will need planet-cnc software, for the parallel interface, you can use any industry standard cnc control software (the typical is Mach3 for Windows, or EMC2 or Linuxcnc for Linux (Linuxcnc.org).

5v power supply is not needed. The 5 volts signal level power is derived from the computer through USB on both types of interfaces.

The drivers have quite a bit of protection, so you probably won't ruin anything. You motors are jumping and that is just the motors engaging from getting power from the power supply.

There could be many reasons your motors don't turn. Consider these troubleshooting tips:

- If you are using our parallel breakout board, make sure that the step pins are set for active low (config -> Ports and Pins -> Motor Outputs -> the steps pins should be enabled and set active low)

- The parallel breakout board is powered (connect the USB to the computer using a USB cable)

- In Mach3, make sure you have jog enabled (a little green button at thelower middle of the page in the program run screen).

My stepper motors stopped working all of a sudden. Mach 3 is running fine, just no signals getting to the motors. The lights on the motor drivers began blinking erratically when this started. Any advice where a problem like this can come from would be greatly appreciated.

I also place the controller very close to the drivers (on the back of the gantry). All of the cables are shielded. The only long cables are the mains power cables and the USB cable. The USB cable is shielded and contains active repeaters.

There is no problem putting all of the electronics in a box and using long cables to the motors. This is the way I did it for a very long time.

Great site. I saw your videos of wiring the Mach3 USB controller. You place the drivers next to the Steppers. This means that you have very long leads to the USB Board? What about the placement of the controlling PC? Is it a problem to have the USB board, PSUs and Drivers in a control box and long leads to the steppers? Thank you.

We sell our ACME screws in total length (overall length you require), but if individual lengths are needed you can contact us via phone (281-815-7701) or email (customerservice@buildyourcnc.com).

A $2.00 order will be a total of 1 inch, but if ordered separately then you will receive 2 of the same length.

For the 1/2'' 5 start ACME leadscrew, what is the length purchased for the $2.00 order? and if you make 2 orders, are you getting two separate rods or 1 rod at twice the length. Thanks.

That depends on a few factors. In most cases, three 3.0 amp motors and drivers will not exceed 8.8 amps of available current. All of the motors would need to be at full torque to reach the 9 amps (3x3). This depends on the mechanical method you are using for each motor, and how you are using the machine. In most cases, only two motors are moving at a time (i.e. 3D carving where the X and Z are moving simultaneously and the y only moves to go to the next row). In traditional cutting profiles, only the x and y are moving simultaneously and the z-axis moves at the location it needs to start cutting the next layer.

With that said, it is ok to add an extra power supply if you feel you need more available current.

Hello. I have bought an RnR Motion Controller and a YL260-A and I have it set up to the AVI from RnR to the VI1 of YL620-A but I'm getting that the RPM varies not like interference but like a drop from max value to min value. What could be happening?

If you were to buy all of that, only thing you'll need is the mach3 software to run the machine.

To answer my own question, I just tweaked the trimmer down for the extruder motor until it stopped extruding during a print, then raised it back up one "tweak" until it started extruding again. Since then I have been able to run continuously without overheating the motor. Sorry for the inexactness of my measurements. Basically, the trimmer started at 12:00. I turned it counter-clockwise to about 7:30 and things seem pretty dialed in.
