  • My Nema 24 motors make high pitched alarm sound when changing directions quickly - what could be the cause? Red LED is lit on Microstep Driver CW230 but everything seems to run fine - is this a problem?

    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.

  • Under what conditions should the LED on the 3d printer driver be lit when the driver is connected to the MB?

    The driver's LED serves to indicate a fault condition. The driver chip has built in protection for overheating and over current. If the LED is on, most likely, the driver will stop until the condition is resolved. If you see the LED on, adjust the vref trimmer. First, connect a multimeter to the pads just next to the trimmer potentiometer and adjust until the voltage is lowered a bit. Alternatively, even though the PCB contains a vast amount of thermal vias and a relatively large ground plane connected to the belly of the driver, there still may be a need to cool the driver chip using a small heat sink. Do this only if you are not satisfied with the performance of the motor at the torque require.

  • I am looking at 2 of your drivers. 1 is the 1/64 step and the other is 1/256. What is the difference between the two?

    Stepper motors are designed to move in specific increments; these increments are called "steps". For example, a common standard is for 200 steps per full revolution. Microstepping is a method to send signals to the motor to move only a fraction of a full step at a time. For example, if a motor has 200 steps per revolution and is microstepped 1/16, then effectively there are 3200 small step movements (microsteps) per revolution instead of 200 larger ones. This makes the motion of the motor much smoother and more precisely controllable, at the cost of decreased holding torque.

  • My cnc router started doing strange things today after about 20 minutes into a fairly simple project. I noticed the red lights were flashing in my 4 Stepping Motor Drivers (24-70. Does anyone know where I should look to solve my problem?

    Can you describe strange a bit further? Also which specific drivers are you using? CW230 or 3.0A driver? or the 6.0A driver or CW8060?

  • there's a red light active on the inside the corner of my cw230 stepper driver, but there's nothing that says what it's for. is that bad? on the cw8060 driver there's two LED's and the red one says alert. are the red light's on both drivers supposed to mean the same thing?

    For the 3.0A driver (CW230), the red led means that it is functioning correctly. It is confusing that they are made this way, but if the red led is lit then everything is fine.

    As the 6.0A driver (CW8060) the green led means that it is functioning correctly, and the red led when there is a error.

  • I recently had a mishap with one of my stepper drivers which resulted in a resistor being burned out. Would you be able to tell me what the resistance is for the R25 resistor inside the 6.0 amp driver?

    Currently we do not know the values of the electronic components inside our drivers, since these drivers are supplied by our manufacture and replaced by them if a manufacture defect is present.
    Please email us at customerservice@buildyourcnc.com for more information on possible replacements.

  • I originally bought 4 Sainsmart ST4045-A1 Drivers. One failed. Can I replace the defective one with one of yours? Or should I replace all 4? I have bought your NEMA24's and BOBs. Learned my lesson. Newbie mistake, I admit. Thanks.

    If you already have our motors and interface controller, it would be best to run all motors with our drivers. You would not be compelled to replace all of the drivers, but it may be advisable for future issues.

  • What causes one of my two x-axis motors to stop while the Mach 3 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.

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.

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

  • The instructions for installing the USB board say there should be a blue LED light up when computer is connected. I get a flashing red LED that goes solid when I start

    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).

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

  • My Question is about the 2.2kw spindle, because the thread start is so small I have a hard time centering the collet before it binds from tighting what have others done to overcome this

    Can you see any damage to the beginning of the thread on the shaft of the spindle, or any damage to the thread on the inside of the collet nut?

    Additional Information:
    There is no damage, I cannot put a tool in without removing the nut and collet when I go to tighten it, it starts to seat the collet and if I cannot hold the tool just right it is off center

    Additional Information:
    The ER collets should actually snap in to the collet nut, which eliminates that issue

  • I purchased a 2.2 spindle a while back and went to the electrical supply house to but shielded cable for the power run, I was on the web a while back and saw a picture of shielded cable that didn't look like what I had bought. should it have a copper like mesh wraped around the inner insulation. Thanks

    Many shielded cables come in various materials and designs, so having one with a copper mesh covering the inner insulator wire is no problem. We currently use a extension cord found locally at a hardware store and include one 18G wire for ground. So a specific shielded cable is not a required, unless being used next to specific and sensitive electronics that are extremely sensitive to noise and voltage interference than a shielded cable is required.

  • I'm planning on purchasing a Greenbull 5x (hybrid laser/spindel). What other expenses will I have for having a fully operationel machine

    You will need to make sure you have a 220 volt outlet near the machine. You will need some wire to connect the electronics unless you purchase the redFly, redLear or redSprout plug and play electronics. To maintain cooling for the spindle, you will need some silicone tubing to provide for water exchange within the spindle, a bucket and pump to pump the water. You will need a table built as per the dimensions on the greenBull page:
    https://www.buildyourcnc.com/greenBullCNCMachineKit.aspx

    For cutting material, you will need end mills which are consumables that will be purchased frequently as they wear.

    The pump and silicone can be found here: https://www.buildyourcnc.com/category/pneumatic-hydraulic

  • Please share what versions of ReplicatorG, Python, Java, Firmware and the Arduino drivers you are currently using for the whiteAnt 3d printer.

    We use the version 0024 of replicatorG which works quite well. The firmware is specified on the videos as you perform the installation. You can find the videos on this page: https://www.buildyourcnc.com/whiteAnt3DPrinterandCNCMachine.aspx

  • What are the toggle switch settings on the stepper motor drivers for the .5 in. lead screw 10 tpi 2 turns per inch? Thankyou!

    On the top of the stepper motor drivers is a grid with the appropriate toggle switch positions for the lead screw being used. If it is 2 turns per inch, the proper toggle switch positions would be 01101110. Try this and see if it works.
