    WHAT MOTOR TUNING SETTINGS?

  • what are all the settings i'd need for mach3 for use with a blackfoot and a redfly?

    These are the recommend values(default) for our blackFoot CNC machine, the acceleration and velocity can be adjusted as high as the motor can rotate without stalling! Suggested increment's will be by 10's.

  • My question about motor tuning for the blacktoe in Mach 3 was for the aceleration and velocity settings what are the recomended settings

    In the customer service live, just enter "motor tuning" and it will give you a list of all the recommended or default settings for our machines. However the acceleration and velocity for the greenBull(other machines) will be an actual determination on your trials. You will want the highest possible acceleration and velocity without the motors stalling, so you can do increments of ten to be on the safe side, if it is too slow try increments of 25.

    The steps per inch is dependent on the microstepping:
    Steps/Inch for the x and y
    Steps = 200 motor steps per revolution x 16 microsteps = 3200 steps
    Inches = sprocket number of teeth x pitch of the sprocket = 14 x .25" = 3.5 inches
    steps/inch = 3200 / 3.5 = 914.28
    This is really a starting point. You will then need to use the mach3 calibration function to get the perfect steps/inch value. Use as long a measurement as possible when calibrating.

    Velocity:
    Start with a value of 1000 ipm. Increase this value with a relatively low acceleration at about 10. You will notice at a particular velocity that it will stall. This is your stall velocity. I would take the stall velocity and reduce it by about 30% to 50% which should give you a good final safe velocity.

    Acceleration:
    Once the velocity is found, raise the acceleration until it start to stall at a low velocity. Reduce the acceleration by about the same percentage to stick with a safe acceleration.

    The acceleration is mostly dependent on torque (current) and the top speed is dependent on the amount of voltage.

    Give some tests with all of the axes running at the same time. If you notice and stalling, reduce velocities and acceleration depending on when the stall happens (top end, or acceleration curve).

  • What settings does I use for controlling the spindle in StepCon/Linuxcnc?

    LinuxCNC has excellent documents; however, I would like to offer our help in case you don't understand the information on that page. So, please use this FAQ (Question #: 13233) to state your questions by submitting additional information below.

    The LinuxCNC spindle control page is found here: http://linuxcnc.org/docs/html/examples/spindle.html

    Additional Information:
    After reading the LinuxCNC page my first questions would be can the spindle be controlled by PWM signal? Also, what pin on the parallel port would I set to Spindle Enable and FRW?

    Additional Information:
    To connect your computer to the VFD, use a USB to RS-485 interface. RS-485 is just a serial interface protocol that uses standard 0 to +5 voltage TTL signal levels for communication (as opposed to RS-232 which uses -12v and +12 for signal level changes).

    Get a high quality interface to reduce any issues during the process. The VFD should have two terminals labeled RS+ and RS-. The USB to RS-485 adapter should have this labeled on it as well so the connections should be relatively straight forward.

    In the VFD parameters:
    PD001: 2 to accept RS485 commands
    PD002: 2 to accept frequency comands
    PD163: 1 to RS485 slave address:1
    PD164: 1 RS485 baud rate 9600
    PD165: 3 8bit, no parity, 1 stop bit

    Make sure LinuxCNC is also set accordingly:

    The PIN14 and PIN16 in the stepconf wizard should be set to unused because you don't want LinuxCNC to be outputting unnecessary signals.

    In the options step of the stepconf wizard:
    - Check the Include Halui user interface component.
    - Check the Include custom PyVCP GUI panel.
    - Check Spindle speed display

    You will want to edit the custom.hal text file located in the folder that was created from the stepconf wizard. Add these following lines:
    loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600
    net spindle-cmd-rpm-abs => vfd.speed-command
    net spindle-cw motion.spindle-forward => vfd.spindle-forward
    net spindle-ccw motion.spindle-reverse => vfd.spindle-reverse
    net on motion.spindle-on => vfd.spindle-on

    The dev folder in linux is typically used for interfacing devices and peripherals to the computer as these devices are communicated by simple memory addresses and these files are linked directly to these addresses.

    Under the custom_postgui.hal file, change this line:

    from: sets spindle-at-speed true
    to: net spindle-at-speed => cfd.spindle_at_speed

    and add the line:

    setp vfd.enable 1

    When you start LinuxCNC, you will a spindle section with the reverse and forward buttons, a stop button and - and + buttons. Use these buttons to conform that the spindle is functioning properly. The spindle speed indicator in LinuxCNC will show the spindle speed and you can confirm that this is equal to the speed indicated on the VFD.

  • WHAT CAUSES ONE OF MY TWO AXIS MOTORS TO STOP WHILE THE MACH3 PROGRAM IS STILL RUNNING

    If one of your stepper motors decides to stop moving and the others are moving during a CNC milling or laser cutting job, then there could be two things that could be causing this.

    - The motor found its limiting torque (usually comes with a not-so-pleasant sound). This is where the control software is trying to move the stepper motor too fast (velocity, or too fast too quickly, acceleration) and the load against the stepper motor (inertia of the machine, or the material against the end mill while milling). Recommended action is to lower the velocity and/or acceleration, and/or lower the feedrate when cutting.

    - There is a wiring issue with the wiring from the driver to the motor. This could be a loose wire, or a chafed wire (or two shorting together). It can also be a loose digital wire from the controller board to the driver. Sometimes wire ties can be the culprit. Recommended action would be to thoroughly inspect the wiring.

    It's probably not the limit switches since that would cause a stop to the entire motion of the cnc router or laser machine.

    Sometimes Mach3 will show a status when something goes wrong, but in cases where the motor is stopping due to its torque limit, then that would not be shown in the status. It's always good to check it anyway.

    Additional Information:
    I need to clarify my situation a little better after going to my shop and trying to run another program on Mach 3. About 15 minutes into the milling process all the motors (2-X axis, Y axis and Z axis)stop but the program continues to run. I stop the program and after a couple of minutes when I try to restart the program all the motors start working again. Then after another 15 minutes or so, all the motors stop again. I checked and rechecked my wiring. This has never happened to me before when running the same programs with the same setups and motor speeds. All of a sudden when I reloaded a program I successfully used before it does this. Do you have any recommendations?

    Additional Information:
    Yeah, it sounds like a more complex issue. Have you tried running in the air without using the spindle. This may be a power related issue.

    Additional Information:
    That's exactly what I did. I ran the program without the router motor on just to see if the motors would get through the whole program but they stopped working after about fifteen minutes and then I was able to start them again after about 3 or 4 minutes. I never had this problem before so you can imagine my frustration especially after ruining a couple of projects on expensive material.

    Additional Information:
    Sure. I can completely understand. Try this: disconnect all but one of the driver from power and digital connection and do the air run. Repeat this for each driver and note your findings. This will rule out the drivers causing a power failure.

    Also, is your stepper motors and drivers on a separate power circuit from the computer?

    Additional Information:
    I will try disconnecting each driver and digital connection, which will be a real pain because it will be hard to access.

    All the stepper motors, drivers and computer are plugged into the same power strip.

    Additional Information:
    Ok, so there is no power failure going on, but I believe it is necessary to test each stepper motor and driver pair individually. Hopefully that will lead to a conclusion.

    Additional Information:
    It will take a little time but I will do it and report back on my findings.

    Additional Information:
    Curious, what machine is exhibiting this problem?

    Additional Information:
    I purchased a BYCNC kit back in 2009 with an approximate cutting area of 2' X 4'. I later changed out the Z-Axis Motor and controller for a larger one and have two X-axis motors and controllers. In 2010 I rebuilt the machine out of birch plywood instead of the particle board that the kit supplied. I sent Patrick pictures to him. The machine never gave me a problem till now.

    Additional Information:
    Thanks for the update. This is Patrick by the way. I answer pretty much all of the Customer Service questions. That machine has given quite a good history.

    Additional Information:
    I love the machine and made a number of samples of my work for my e-commerce site, but I can't start selling product until I know this problem is solved because I will not be able to fulfill orders. I finally got all the electronics out of its enclosed protected area near the machine so that I test each controller as you recommended. I hope the problem can be rectified. Will let you know.

    Additional Information:
    Thanks.

    Additional Information:
    I tested each stepper motor and driver pair individually and they worked so what might be the next step?

    Additional Information:
    Did each stepper motor driver pair work for the full +15 minutes?

    Additional Information:
    Yes, I had them in operation for over 30 minutes.

    Additional Information:
    Ok, well it’s good that the motors and driver are ok. We are now down to the power supply and the breakout board as possible causes for the stop. I have a feeling it may be the power supply where with all three drivers drawing current and the power supply maybe getting too hot. Is the fan in the power supply working? You can also test to see if there is 36 volts on the power supply voltage output (V+ and V-).

    Regarding the breakout board, if you have an oscilloscope, you can test if the driver pulses are outputting, but I would consider this as a last resort after you determine if there is a problem with the power supply.

    Additional Information:
    I tested the power supply with a voltmeter and each output was registering 39-40 volts. I think the problem may be the g-code. I am using V-Carve pro to do design and output to Mach 3 Mill g-code. When I studied the g-code lines I noticed that further into the program the z-axis g-code stopped zeroing out to move to the next part of the carving. In other words both the x and y keep moving and the z just stopped working because there was g-code missing. I think something is missing when the design was converted to g-code. I noticed that when I ran a simpler project it worked without problems so I need to investigate this further.

    Additional Information:
    New Update, Its not the g-code. I started to run the long program and everything was working fine until about 45 minutes into it, all the motors stopped working (but the program was still running) and there was a high pitched hum. When I put my hands on the motors they were all trying to move but it seemed they were all stalled. I turned the power off, gave it a minute and when I turned it back on I was able to move the motors again. Could this be a power supply problem?

    Additional Information:
    It does sound more and more like a power supply problem. Did you test the power supply after the motors stopped?

    Additional Information:
    No, I did not. What should I be looking for.

    Additional Information:
    It’s good that you know the voltage during normal operation, so you have a base understood. If the power supply is the problem, the voltage will be reduced or non existent when measured after the problem.

    Additional Information:
    Also, check to see if the fan is running on the power supply when the motors stop. That may (not absolutely) be an indication.

    Additional Information:
    I'll run another test, check the voltage and fan when the problem occurs and let you know. Thanks for hanging in there with me as we try to resolve the problem.

    Additional Information:
    It’s my pleasure. This service is rarely used and is faster then email. Odd nobody uses it. Any recommendations you can give would be great. No problem using this FAQ to pose ideas as this resolution will be cleaned up later.

    Additional Information:
    It might be that people do not realize you can communicate through the sight like this because they are so used to e-mail and texting. You may want to explain this feature in the customer service section.

    I ran the program this morning and it did not take long before the motors stopped. While operating the voltages for all three motors was 46 volts, when the motors stalled (and again there was a high pitch hum) the voltage went up to 60 volts and the fan on the power supply was operating.

    Additional Information:
    So, the driver work individually, but not all together. There is a high pitch sound when the motors fail. You have noted 60 volts from the power supply and the supply fan remains on. This is a difficult issue to resolve, but it seems to me that your power supply may be bad. The 60v measurement tells me that the current dropped and ohms law tells us that is current drops, volts will rise if the resistance stays the same.

    Additional Information:
    As one last test I am going to test each driver again and let them go through the entire program because it seems that the failure can occur at the beginning or towards the end of the program. When I originally tested ach driver I let them run for about a half an hour and the program takes over an hour to run completely. I just want to make sure that it is not the drivers. I will report back when I finished but as you noted it may be the power supply but I want to make sure.

    Additional Information:
    That’s a great idea.

    Additional Information:
    I just ran the x-axis through the whole program and there was no problem especially since I have two NEMA 23 motors moving that axis. Before I check the Y and Z could having a NEMA 34 on the Z axis with appropriate controller be a problem. I used the larger motor on the z axis because the router I am using is a large 1 1/2 hp. I've run this program in the past with this set-up and have not had a problem.

    Additional Information:
    Having a, say 3.0 amp driver, driving a stepper motor that typically requires a 6 amp driver would not seem to be an issue since the driver is limiting the current draw, but the driver may not be able to handle larger coil and back EMF with the protection on the 3.0 amp driver. With that said, I don’t believe that is the issue in this case.

    Additional Information:
    I don't either because I was able to run this and other complicated programs with this set-up in the past. I will let you know on the y and z axis.

    Additional Information:
    Thanks

    Additional Information:
    I ran the Y axis and z axis separately through the entire program and there was no stopping or problem. I guess the culprit is the power supply and I'll order a new one and hope that resolves the problem.

    Additional Information:
    Yes, that is the most probable cause. Please keep me informed. Thanks!

    Additional Information:
    Received and installed the new power supply. I ran the program with the router on and it worked flawlessly. The program runs for an hour and a half and I did not have a single problem. I guess it was the power supply but I was glad to go through all the diagnostics we discussed before replacing it. I hope this power supply lasts a lot longer than the last one. Thanks much for hanging in there with me and coming up with the solution.

    Additional Information:
    It’s my absolute pleasure and I am so happy to hear that the power supply replacement solved the problem.

  • I'm using Mach3 and I tuning the motors. As is they all seem to jog nicely, smooth and quiet. However when I make moves using gcode they bind and don't move or jerk violently when they do move. What step did I miss?

    Your g-code probably has the feed rate too high. You set the velocity and acceleration in your motor tuning, but g-code may be able to override these values.

    Try lowering the feed rate in either your CAM program or in the g-code manually. The feedrate code has an “F” then a number after representing the velocity.

  • While motor tuning what are the recommended steps per inch, velocity, and acceleration for the GreenBull CNC?

    In the customer service live, just enter "motor tuning" and it will give you a list of all the recommended or default settings for our machines. However the acceleration and velocity for the greenBull(other machines) will be an actual determination on your trials. You will want the highest possible acceleration and velocity without the motors stalling, so you can do increments of ten to be on the safe side, if it is too slow try increments of 25.

    The steps per inch is dependent on the microstepping:
    Steps/Inch for the x and y
    Steps = 200 motor steps per revolution x 16 microsteps = 3200 steps
    Inches = sprocket number of teeth x pitch of the sprocket = 14 x .25" = 3.5 inches
    steps/inch = 3200 / 3.5 = 914.28
    This is really a starting point. You will then need to use the mach3 calibration function to get the perfect steps/inch value. Use as long a measurement as possible when calibrating.

    Velocity:
    Start with a value of 1000 ipm. Increase this value with a relatively low acceleration at about 10. You will notice at a particular velocity that it will stall. This is your stall velocity. I would take the stall velocity and reduce it by about 30% to 50% which should give you a good final safe velocity.

    Acceleration:
    Once the velocity is found, raise the acceleration until it start to stall at a low velocity. Reduce the acceleration by about the same percentage to stick with a safe acceleration.

    The acceleration is mostly dependent on torque (current) and the top speed is dependent on the amount of voltage.

    Give some tests with all of the axes running at the same time. If you notice and stalling, reduce velocities and acceleration depending on when the stall happens (top end, or acceleration curve).

  • 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

  • I'm building my own machine using your motors and drivers. What is the best dip switch settings for the 3.0 amp drivers powering the 425 oz motors

    The settings that you will use for your 3.0 amp driver to properly power and turn your 425 oz-in stepper motor will cheifly depend on your application and the mechanical parts you are using on your machine. In all circumstances, the amp setting for the stepper motor (according to the datasheet) should be 2.8 amps. Use the closest setting on the driver without going over.

    Here is a good rule of thumb for the microstepping which will correspond to the resolution, but wil also affect torque. You always want to try to achieve the best torque and resolution for the axis you are moving but go with the lowest microstepping possible. In cases where there is mechanical advantage, like a lead screw scenario, where for each motor revolution, the axis move a very small amount, you will want a very low microstep value. This is because the mechanical configuration will provide most of the finer resolution and you will not need the microstepping to assist in this. Increase the microstepping only in conditions where the axis is not moving smooth enough, or where there is a mechanical disadvantage. A mechanical disadvantage would be where the stepper motor is causing a great amount of movement in the axis and the resolutions suffers from this condition. Increase the microstep value up to your desired resolution, but don't go over since the torque of the motor will decrease.

  • I am asking what to set my steps per using your kit stepper motors and a 1/2"x13 lead screw with Mach3

    Here is the formula for steps/inch (steps per inch)

    Steps = how many steps for a full ration of the motor = standard motor steps x number of microsteps for each step
    Standard motor steps for our stepping motors is 200 steps per revolution.
    Microsteps are selected on the driver and are shown as full, 1/2, 1/4, 1/8, 1/16, 1/32 etc... Use the denominator for the number of microsteps per step.

    Inches = how far the travel is for one full rotation of the motor. For the 1/2" - 13 TPI (threads per inch), the travel length will be 1"/13 or .076923". So, for one revolution of the motor, the travel distance will be .076923 inches.

    So, the steps = 200 * microsteps, let's make this 1/4 just for the formula.
    The inches will be .076923. Plug those into the formula:
    Steps / inch = (200 * 4) / .076923 This can also be written as:
    200 * 4 / (1 / 13) = 10,400
