Question #: 15066

Question: [Mach3 USB Interface Board] Why is a second PSU necessary for the limit switch and e-stop ?

Current Solution

Because the USB board is powered by USB (+5VDC) from your PC. Your inputs (eg. limit switches) require up to +36VDC to operate properly.

  • Do you sell 22 to 24 AWG stranded and shielded for wiring of the limit switches and E_Stop?

    The wire that we sell for the limit switch wiring is here: https://www.buildyourcnc.com/item/3d-printer-component-cnc-electronicsandmotors-cable-wire-3-conductor-22-awg-wrcon-cablewire3conductor22awg

    This is shielded cable to make sure there isn't any external interference with sensitive components and long wires associated with limit switches. This is necessary due to the interference caused by the motors on a CNC router and the milling process.

    Additional Information:
    So unshielded is cool. That's what I was curious about. Cheers.

    Additional Information:
    Absolutely. It's really the only type of cable I would recommend for connecting limit switches.

  • 2017 Mach 3 usb motion card not translating commands to machine. Second green led by limit switch terminals. Seem new. MDI won't move spindle. Any Ideas?

    The mach3 USB controllers that we stock don't have green LEDs. Can you tell me what brand you are referring to?

  • Do you have a more detailed diagram of the rotary and 15A limit switches on the vlxl?

    Are you trying to determine how to wire the switches or where to place them on the Vertical Laser XL? Let me know and I will provide some pictures or video on how to do this.

    Additional Information:
    Kind of both. Have somewhat of an idea as to how to wire them but you included rotary and other limit switches. Not sure which ones to put where. Never worked with these before.

  • WHAT IS D.O.F OR DEPTH OF FIELD FOR THE BLACKTOOTH LASER AND LENS?

    Depth of Field. This is how far the focal point goes before re-expanding again. With a 2" lens, you have approximately 2-3mm of DOF. This means that you'll have 2-3mm of perfectly focused laser before it starts to re-expand again. If you have a 4" lens, you will have up to 7mm of DOF.

  • After limit switch is activated on planet cnc control software, what do I need to do to get axis to move again?

    Looking for a solution myself. Proper operation would be for the limit switch to only disable further travel in the effected direction while still allowing travel in the opposite direction.

    As for now, I am just using the jog arrows within the software or the VGA controller.

  • [575] Is there a way to use an X,Y plate that will only be responsible for corner finding?

    Yes, you can use a corner plate very easily. You will want to make a corner plate that has three independent plates that do not conduct with each other. Each of these plates will be connected to a different input (i.e. IN1 for X, IN2 for Y and IN3 for Z). The end mill or tool that is inserted into the spindle will connect to V- of the 24V power supply, or the DCM on the controller, which is connected to the 24V V-. Then, you can use the ref all home button on the program run screen of Mach3.

  • [575] can the handwheel inputs be used for thc

    I have not tried using the handwheel inputs for anything other than for handwheel operation. I haven't had success using a THC with the Mach3 USB controller. The pokeys57CNC controller is a better solution for THC (torch height controller) and plasma cutter use.

  • [575] I cant get a 5v signal on any of the Outputs on the board. what Port# and Pin #s should I be using on Mach3?

    The Mach3 USB controller does not provide 5V output signals. The Inputs, Outputs, and PWM Spindle Speed terminals are separated from the 5V side of the board. The output terminals use the 24V portion of the controller and you will need a 24V power supply to make these outputs work.

    Please watch the video below to completely understand how the outputs of this controller work. Make sure that you are using the RNRmotion.dll plugin and that the port for each of the outputs is set to port 3.

  • WHAT IS THE DIFFERENCE BETWEEN A PRINTER CABLE PORT AND USB MOTOR KITS

    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.
