This is correct if it is the Mach3 USB controller. You will also get a rapid flashing led if you jog the machine (assuming the machine is not in reset mode or e-stop mode).

Is it suppose to be blue or red? Mine is red.

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.

You can find a diagram that describes the pin-out for the 2.5 am Driver that is intended for the 3D Printer Main Board, but can be used as a standalone driver as well.

The whiteAnt will work with a 6 amp 12 volt power supply. If you add more peripherals to the machine, like heating bed, you will want higher current. Each motor draws 3.0 amps at full torque. Most of the time, only the x and y axes are moving at the same time, and the drivers are only allowing a max of 2.5 amps and they should be set for about 2.0 amps so they don't overheat (they have overheat protection and the LED will light up, so you will be fine if it does overheat, but your model may suffer). The remaining current will be enough to keep the hot end heated.

IF YOU HAVE CIRCUIT (OR PICTURE) OF HOW THIS RELAY IS CONNECTED TO THE ROUTER

The parallel breakout board has a relay that can turn the router on and off according to the control software in the computer. The router will turn on automatically prior to the machine moving (a time frame can be set so the router is up to speed). When the machine is finished and is not moving, the router automatically turns off. This is with the m3, m4, and m5 codes in the g-code.

If you are interested in the USB breakout board, you will need to get an independent relay board.

HOW CAN THE ROUTER BE CONTROLLED OR CONNECTED TO ELECTRONICS COMPUTER?

The parallel (printer cable) port is uses the computer as its main source of pulse trains to operate the motor driver directly. Parallel ports are a direct connection from the processor commonly referred to as GPIO pins (General Purpose I/O pins) and provides a convenient and powerful way to interface with the computer. The parallel breakout board is included in those kits only to condition those signals for use with the drivers.

The USB serves at the actual controller, sending the pulse trains, but the computer sends simple human readable instructions to the USB controller to tell the controller how to send pulses.

The non-technical differences that may serve as the most important information to you is that the parallel configurations allow for a wider variety of industry standard software that can be used to control the cnc machine. The USB that we offer requires the operator to use a software called Planet-CNC software which is a very well made and feature full cnc control software.

The recommended total length of motor cable should be 15 feet for the blueChick v4.2

Z - 6 feet

X- 4 feet

20 AWG 4 conductor

If your drivers will be positioned farther from the machine, you may need longer cable.

Does your breakout board (interface) have a relay? If so, you can connect one of the router/spindle's ac lines through the relay. The M3, M4 and M5 codes are used to control the router/spindle. Typically, the M codes are automatically added to the g-code regardless if you configure this in your CAM software. If you have the breakout board from buildyourcnc, you can go to the product page for the breakout board and the relay connection diagram and narrative is in the instructions on that page.

To convert the whiteAnt to a CNC machine, you will want to lower the upper structure to the lowest position to create the most rigidity overall. You will see that there are many holes below the sides of the upper structure that are evenly spaced. This is so you can adjust this lower. You will also want to fasten the lower sides to a substrate (piece of wood, or something) with l-brackets or something that has a bit of adjustment capability. This will keep the sides more rigid as well. Use a Dremel for the spindle. If you want to use a another spindle, let me know and we can product a mount for that spindle since the Dremel has poor runout (TIR). This is important if you are wanting really precise milling.

Mounting the extruder to the whiteAnt can be done a couple of ways. One is to take the 4 mounting holes located at the lower portion of the z-axis rail support and use long screws protruding out. Take a thinner material and drill the four holes matching the locations of the 4 screws and screw on nuts to hold it in place. The other option would be to use the metal bracket and fasten to the edge of the rail support.

It seems to be getting some kind of interference or a short within the wiring or communication, try jogging the motors in the software without anything wired to the board. Then add one motor at a time to see if there is a short within your wiring or a faulty driver/motor.
If the USB breakout board continues to move the x-axis with no motors or driver wired to it, please email customerservice@buildyourcnc.com for a replacement or further troubleshooting.

Yes, you can use lubrication, like 3-in-1 oil to make it a bit easier. You will need to run it up and down to break it in.
