Question #: 14136

Question: Are the motors for the 5x suppose to operate at a high temperature?

Current Solution

Yes, all of our stepper motors will run hot, depending on the way it is operated. Energy comes in a few forms, light, motion or heat. If the stepper motor is not moving, it is typically holding its position, which will cause the energy to transform to heat energy. If the stepper motor is holding a load, and is moving, it is drawing more current and the energy will be in the form of heat and motion.

It is totally normal for stepper motors to be hot to the touch.

  • Are the stepper motors on x and y axis suppose to be hot after running for approximately 30 min. I can touch them but they are hot.

    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.

  • What kind of cooling system should we set up for the Blacktooth laser cutter laser tube? Can tap water be used? Is water temperature critical?

    The blackTooth's 40 watt laser tube can be cooled with simple tap water. A bit of anti-freeze keeps the tap water clean and free of algae. The cooler the water, the better output you will get from the laser. A great source of information can be found here: http://www.buildyourtools.com/phpBB3/viewtopic.php?f=8&t=3452

  • I have theNema 24, 425 Oz stepper motors kit what are my Ports and Pins?

    The ports and pins are designated by the breakout board that you have, Now here are the schematics for both(https://www.buildyourcnc.com/item/electronicsAndMotors-parallel-breakout-relay#prettyPhoto/2/ and https://www.buildyourcnc.com/item/electronicsAndMotors-electronic-component-USB-Controller-Breakout#prettyPhoto/2/) Which for the Parallel the pins will be 1,14,2,3,4,5,6,7,8,9. For 1,14 you will need to use them together for a additional axis. Setup will be (ex.mach3) step in (2) / direction pin (3). continued for other pins, 4,5 6,7 etc.
    Now for the USB it has the label on the board right next to the terminal blocks, x-axis/etc.

  • Whiteant- In the software there is a configuration for a heated bed. Where would I wire this in the kit's electronics if i bought one? Would the temperature be on/off or PID?

    Currently we planned on having upgraded electronics with the whiteAnt 3D printer, which would have had the ability to support the heated bed, and other options. Which is why there was a configuration file in the downloadable files. However in newer developments we have been working on our prototype blackAnt 3D printer which will have the upgraded electronics and the option for the heated bed, but currently our whiteAnt cannot support the heated bed with the gen4 electronics supplied with the kit.

  • If motors are wired for Bipolar series which leads do you swap for rotation?

    For our motors, drivers and power supplies, we recommend bipolar parallel (relating to motors with more than 4 wires). The current draw and voltage combination under bipolar parallel results in better performance.

    To reverse the motor spin direction for both bipolar series or bipolar parallel, switching the "A" wires with the "B" wires will do the trick.

  • DON'T WANT TO USE MY OWN MOTORS FOR THE REDLEAF CNC COMPUTER SYSTEM.

    That shouldn't be a problem. I will need the current rating for the motors. We can subtract the price of the motors. and you can add you own. If you want us to solder the cable to the round connectors and them motor, you would need to send the motors to us.

    Let me know and I can send a paypal invoice for the redLeaf without motors.

  • ARE WE SUPPOSED TO GIVE INFANTS PRESERVATIVE-FREE INFLUENZA VACCINE?

    No. CDC and ACIP express no preference for preservative-free vaccine for infants or any other group of vaccine recipients. See page 22 of the 2010–11 ACIP influenza recommendations: www.cdc.gov/mmwr/pdf/rr/rr5908.pdf.

    No scientific evidence exists that thimerosal in vaccines, including influenza vaccines, is a cause of adverse events, unless the patient has a systemic allergy to thimerosal. However, some states have enacted legislation that restricts the use of thimerosal-containing vaccines. Check with your state immunization manager to see if your state is one of them (www.immunize.org/coordinators).

  • With the Mach3 USB board, my stepper motors are moving or spinning slowly.

    If your motors turn very slowly using your Mach3 USB board, then either the pulse from the board is being output at a slow rate or the motor drivers are set to a higher than expected microstepping:

    The Mach3 USB board outputs the pulse rather than the computer, but Mach3 controls this pulse frequency within the motor tuning section. First, determine if the travel distance is correct with the computer and the physical travel of the machine.

    If the travel is different, then your stepper motor driver's microstepping is incorrect, or the steps per inch/mm in the motor tuning within Mach3 is incorrect.

    If the travel is correct, then simply change the velocity and acceleration parameters to your desired level. If Mach3 will not achieve the velocity you desire, then decrease your stepper motor driver's microstepping setting, readjust the step per inch/mm in mach3 and readjust the acceleration and velocity to your desired levels.

  • Can anti-freeze be used as a coolant for your 40W laser tube? I live where winter temperatures are below freezing and my CNC machine is in my unheated garage.

    Using Anti-Freeze in the cooling system with either our spindle or our laser tubes will not have any problems and we recommend using a small amount in locations where temperature is freezing or below.
    Although we do not recommend using an entire gallon of anti-freeze rather just a small quantity with tap water will be sufficient.

    Additional Information:


    Additional Information:
    All last winter, the temperature was below freezing and sometimes below zero. I used 100% antifreeze for the spindle coolant. Worked great !! All the spindle needs is any type of coolant flowing through it to take the heat away. I use three gallons of antifreeze in a tub with a fish-tank pump to push the antifreeze through. 100% antifreeze works great in cold or hot winter.

    Additional Information:
    Excellent tip. Thank you for this correction. So it is OK to use antifreeze solely as a cooling method.

  • My x and y motors are on each end of my gantry do I wire each motor to the same XP

    I'm not sure what you mean by XP. Can you clarify? Thanks.

    All stepper motors must be wired to their own stepper motor driver. If two motors need to be driven by one signal (say there are two X motors) then the two drivers will be connected to same CP (pulse or step) and CW (direction) pins on the control interface. If the two motors need to turn in opposite directions, then swap the A and B coil connections.

    Additional Information:
    Whitch A+ or A - B + or B -

  • What wiring should I use to connect two motors for one axis?

    Yes, you can use 2 motors in the same axis output, however you will still need a driver for that motor! Also depending on the orientation on which you mount the motor you might have to invert the direction of the motor, and that will be simple by swapping the A+,A-, to the B+,B- locations and vice versa, from the driver to the motor wiring.

    Also you can run a slave motor using another axis on the board, and setting it up in the Planet-CNC settings.

    Planet-CNC/File/Settings/Axes, here you will enter 3 in the Number of Axes location, and then change the Function of the Axis 4 to Slave 1. There you will have the 4th axis or A-axis be a slave for the x-axis.
    Slave 1 - X-Axis
    Slave 2 - Y-Axis
    Slave 3 - A-Axis
    Slave 4 - B-Axis
    Etc...
