Question #: 903

Question: I am looking at using a laser on my 6X6 3 axis table what do i need?

Current Solution

To add CO2 laser functionality to your existing CNC machine, you will need everything listed on this page: https://www.buildyourcnc.com/LaserComponents.aspx

The number of mirrors and mirror mounts will depend where and at what orientation the laser tube will be mounted in the machine. There is already a mirror mount in the head/nozzle unit, so keep that in mind.

Other Possible Solutions to this Question

  • what parts would i need from you to convert my cnc plasma table into a laser cutter? price?

    First, you would need a laser tube, laser power supply, laser controller and a lens holder. You may need mirrors and mirror holders if you plan on orienting the laser tube in a direction other than directly towards the work surface.

    You can find these items and prices here: https://www.buildyourcnc.com/LaserComponents.aspx

    You will need to mount the laser tube and power supply. We recommend mounting the tube and power supply to the gantry, or directly to the axis that moves across the gantry for reduced power loss and to eliminate slight drift from mirror alignment error.

    The controller will need to be connected to your existing motor drivers. If you wish to still use your plasma table for plasma cutting work, you will need to have a switch and transistor circuit to switch which controller has precedence to control the drivers (having both controllers connected to the drivers, but having a TTL circuit using buffer/gates chips that is controlled by a single switch. We can assembly this circuit for you for a fee.

    If this is a machine that we did not manufacture, you will need to create the mounts for the laser tube. We can provide guidance for a fee if needed.

    Additional Information:
    Will my existing controller not work for controlling both? What would I need to make the laser cut when the table moves. The table has a thc and enable disable circuit. Also when will the mirror mounting head assembly be in stock again?

    Additional Information:
    I'm not familiar with the controller that you use for plasma cutting. The principle is probably the same. There is two main axes for movement and a trigger signal to start the plasma cutting. Not sure if your plasma table contains a z-axis that follows closely to the work surface to get the most efficient arcing. That function could be helpful, but not necessary for the laser.

    If your controller has a standard digital level trigger control, then that would be fine.

    Laser controller have the ability to create raster style engraving. If you don't need this functionality, then a laser controller may not be needed.

  • When using the laser controller, what does "engrave beyond border limit" mean?

    LaserCAD: Engrave beyond border limit.

    This is caused by a sweeping motion that is too fast and where the acceleration is too slow. My recommended action would be to keep the acceleration the way it is and slow down the speed of the engrave sweeping motion. I typically use around 200-300 mm/sec and make sure that the axis sweep motion is the nozzle along the gantry, not the gantry itself. The gantry will have too much inertia to sweep, but the nozzle is very light and can sweep very quickly.

    Specifically, what is happening with the engrave beyond border limit is where that axis is not able to slow down fast enough to not hit the border. For instance, imagine a car going 100 mph and it needs to stop within 30 feet. This would not be possible because the deceleration is not high enough.

  • Ok, been lurking for a long time and trying to determine motor size for my application. I am a woodworker and only looking to 3 axis, and trying to determine motor size. I imagine a PC7518 as my motor and table 2'x4'

    Dealing with the motor sizes and what you will be designing structure wise, being a metal structure or wood structure. Also the which method in driving your axis, being roller chain with sprockets, or lead screw/guide rails etc.
    Now for a 2' x 4' CNC machine a good overall machine will do excellent with our 425 oz inch 3 axis electronic combo, but if you are looking at a stronger firmer and industrial purpose machine our 651 oz inch 3 axis electronics combo will be your best choice.
    Now for your router that will be your preference on overall performance and affordability, we recommend a PC 890 series, although we preferably choose a spindle/inverter combo for the maximum life expectancy over any router and the 90% cleaner and 70% quieter over any router out today!

    Additional Information:
    Thanks for the reply. I'm a newbie to CNC so the options seem daunting to find the best solution. I'm a woodworker for 25 years, and by trade an IT Manager in manufacturing. So I'm very familiar with sketchup-pro where I design my pieces. I have watched your vids and Since my purpose will be cutting ply, and mdf, and solid wood mostly cherry for parts, I want a motor that is on par with my 7518. I'm thinking spindle since I'm afraid a standard router will overheat. As to motion type, I'm still learning which to choose. I don't know which is better chain leadscrew or rack and pinion. Obviously my budget is not unlimited, so the 3k range is where I'd like to stay.

  • 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 DON'T HAVE A PARALLEL PORT ON MY COMPUTER. WHAT DO NEED?

    If your computer does not have a parallel port, all you will need is a low cost PCI parallel adapter card (these can be found on amazon for $15-$20). If you plan on using a laptop (not recommended) you can try to find a PCMCIA parallel adapter, but many people have frequent issues with this setup. A more expensive solution would be to purchase a USB smooth stepper board. Unfortunately, we do not supply any of these adapters and cannot attest to their reliability.

    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.

    What causes one of my two x-axis motors to stop while the Mach 3 program is still running?

  • 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.

  • I am looking at purchasing the greenbull 5X system with the laser/spindle combination. Can the laser do both rastered engraving as well as vectored cutting with the same breakout board and software? If I have this wrong please let me know what would be needed to accompish this.

    You can do raster and vector engraving on the greenBull laser/spindle combination. The methods of this process is not accomplished in the same way as the typical laser machines where CorelDRAW is used. The Mach3 laser plug-in can be used for the raster engraving and standard CNC g-code can be used for vector cutting and engraving.

    The raster method will not be fast on the greenBull since the z-axis is heavy and there are inertial limitation on doing fast raster back and forth movement. Vector is the best use of this machine.

  • Have checked stepper motor wires dozens of times and they are wired like diagram says. Stepper motors will not turn under power. I am using laser control option. What should I do?

    This sounds like a problem with the step (pulse) signal. The driver motors receive two signals from the computer via the board -- one is high or low and tells the motors which direction to turn, one is a square wave pulsed signal(quick that tells the motor to turn or a constant high signal that tells the motor to maintain its position. With an oscilliscope you can check for proper signal at the board. If you bought the board from us, please contact us to arrange a return authorization.
