Question #: 3429

Question: I'm planning a rack and pinion style gantry, and need clarification on how to slave a second stepper to the Y (or X). Can you direct me to that information for your products?

Current Solution

There are two things to consider when using two stepping motors on a single axis. Since you want both motors to spin at the same rate and possibly in the same direction, you need to connect both motor drivers to the same breakout board pins. For example, if you want two motors on the x-axis and the x-axis pins on the breakout board are #2 for step and #3 for direction, the #2 will connect to the step (cp) terminal on each driver and the #3 will connect to the dir (cw) terminal on each driver.

However, if the motors will be opposing (one motor will need to spin in the other direction), you will need to consider either flipping the rack on one side, or adding a circuit to invert the direction (#3) signal going to that driver.

I am planning to build a scratch CNC machine to do rotary engraving on writing pens. Can you recommend the parts I would need? I'm thinking NEMA 14 (11?) and 3/8" acme rod. Not sure which linear motion to use. I have an old lathe to use for the 4th axis.
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.

LIMIT SWITCHES FOR AXIS. THE PRINT SHOWS THAT YOU CAN WIRE LIMITS EITHER N.O. OR N.C. SO IF THIS IS CORRECT I WOULD NEED TO TELL BOARD IN SOFTWARE HOW LOOK AT THESE LIMITS, I'M GOING GET AN INPUT LOOSE DEPEND ON IT.
BYCNC Response:
This is correct. You will need to use a method appropriate for the software you are using. Also remember that NC switches are typically wired in series, while NO switches are normally wired in parallel.

User Response:
I am using the cnc planet software for your USB board. Are the limit configurations in this software?

BYCNC Response:
Yes, Planet CNC software is compatible with the use of limit switches. Configuration information will depend on your specific application. You can view Planet CNC's information here: http://www.planet-cnc.com/files/CNCUSBController.pdf

THEY ARE ASKING FOR THE ACTIVATION CODE AND SERIAL NUMBER USB BOARD. HOW CAN GET THAT INFORMATION?
To get the activation code, all you need to do is plug the USB board into the computer using a USB cable, go to machine -> firmware -> update. After the firmware is updated the program will present to you a dialog box containing the activation code.

Wiring the greenBull stepper motors, in the video you say to look at the data sheet for the motor, which is the 651, in the data sheet it shows A, B, C, D, for the colors, and in the video you say A+, A- and so on. Is there a video for wiring the connection to the RedFly that I bought to better explain what I need to do next. I'm using 16c4 SO cord, so I can match color to color on the motor side.
The upper right hand corner of the data sheet found at https://buildyourcnc.com/Documents/PN.SM86HT80-5504B-U(inhouse%20PN.85BYGH450A-47-80)%20(1).pdf labels the coil wires A-D and also by color, which refers to the colors coming off of the motor. Our specification for A+, A-, B+, B- follows the labeling of the driver connections where A+ is coil A's positive lead and the same for the B coil. If you find yourself wiring 4-wire stepper motors without a datasheet, you can easily determine which colors go together with an ohmmeter. Each pair associated with the same coil will have continuity (negligable resistance) between them.

I'M SEARCHING FOR INFORMATION ABOUT THE HEALTH RISKS OF CELLULAR ANTENNAS' RADIATION. I NEED SCIENTIFIC (SCIENTIFIC PAPERS IN JOURNALS) THIS.
Cellular telephone base stations are low-powered radiofrequency (RF) transmitters which operate at around 850-900 or 1800-1900 MHz (depending on the technology and region of the world). RF energy in a similar frequency range is used by many other technologies such as microwave ovens, UHF television, other communications systems, and radar. Health and safety issues related to RF energy have been studied for many years and there is an immense literature on the subject. Here are some sources that review health and safety issues related to RF energy from cellular base stations.

A fact sheet published by the World Health Organization. There is also a Spanish version available on the WHO EMF website.
Also see the IEEE EMBS Committee on Man and Radiation Report. Other reports are available through its website.
The International Commission on Nonionizing Radiation Protection (ICNIRP) has published a lot on health and safety of RF energy. See its website. The ICNIRP published an article that describes the ICNIRP exposure limits for RF energy and their scientific rationale. See "Guidelines for Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields (up to 300 GHz)," Health Physics Vol. 74, No 4, pp 494-522, 1998.
A very detailed assessment of the scientific evidence related to health and safety of mobile telephones and base stations is in the recent (May 2000) report by the Independent Expert Group on Mobile Phones (IEGMP) titled "Mobile Phones and Health" This study concludes "the balance of evidence to date suggests that exposures to RF radiation at levels below [international exposure guidelines] do not cause adverse health effects to the general population" but that "there may be biological effects at exposures below those guidelines." Public exposure to RF energy from cellular base stations is invariably far below the ICNIRP exposure guidelines.

"A Local Government Official's Guide to Transmitting Antenna RF Emission Safety: Rules, Procedures, and Practical Guidance."
An excellent technical paper with field measurements of cell-tower emissions was published by R.C. Petersen and P.A. Testagrossa in the journal Bioelectromagnetics, volume 13, page 527ff, 1992.

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.

I am building a machine that requires 2 steppers to drive the Y axis, can you make me a redleaf system using the 651oz steppers that will work for me?
Yes, we can make a redLeaf system that has all 6A drivers for use with the 651 oz-in motors. We can also wire the electronics in a way that two of the drivers will use the pins of the same axis so that axis will drive two drivers and motors.

I'm using the big 651oz in stepper motor for X and Y and the smaller 325 for the z and X and Y keep tripping when I try to tune the motors on Mach3 but Z seems to work. I have to turn power on and off to reset....is this a wiring issue?
This is most likely a wiring issue. I would disconnect all of the power to the drivers and reconnect one at a time to isolate the problem.

Additional Information:
that was not helpful. I already did that way before submitting this question. there are not that many wires here and I have already rewired this a few times. I actually think its a software or interface board issue because it does work sometimes but then trips (possibly a amperage / voltage issue) I am using the interface board that has a parallel port and usb for 5V. are there different settings that I need to setup?

Can I connect a 36V power supply to 2.5 AMP Stepper Motor Driver. On the actual driver it shows 12V - 24V, but in the description and data sheet it indicates that it can accept 8V - 45V. Will I benefit from more powerful power supply. Thanks
The 2.5 amp driver can only accept a power supply between 12 volts and 24 volts. If a 36 volt power supply is used for this driver, the main driver chip will exceed its maximum voltage rating and cause failure.

If you need to spin your motor faster, you can either use a more appropriate driver (i.e. 3.0 amp driver) or you can change the mechanical parts so the axis has faster travel.
