Question #: 13867

Question: USING MACH3, MY MACHINE STOPS IN THE MIDDLE OF A PROJECT. HOW CAN IT BE STARTED AGAIN FROM POINT STOPPED?

Current Solution

Dealing with a mid-stop cut via Mach3, you will have to be careful if it is intentionally or unintentional. If you desire to stop your machine while in the middle of a cut be sure to stop it when the machine is moving in an upward motion on the z-axis and the X/Y-axis are stationary. Then you can choose the point (G-code) where the machine was left off and click on the Run from here button on the Program Run screen (left hand side) right above the Reset button.
(Make sure spindle/router is running before hand!)

Now if the machine stops unintentionally, and was moving in either the X/Y-axis, then it will be difficult to run the machine from the original point dealing with the coordinates might have been lost due the the machine continuing motion but via Mach3 the machine has stopped.

If this occurs to fight this issue before hand, is marking your home with the spindle/router to make a hole were your home is. Although moving it manually back to home the machine can be off by the smallest amount and could cause an inconsistent cut. If accuracy is something that can not be risked, then you can home the machine about a 1/4" or 1/2" down from the original home to start your cut on the same material but loosing that small piece.

Additional Information:


Additional Information:
My typical go to solution is:

- Note the current g-code line where the machine stopped.
- If Mach3 errored and you cannot control the machine, Exit Mach3 - you may find that reset, stop does nothing to stop the spindle. When you exit mach3, the spindle will stop automatically.
- Restart Mach3. The DRO (Digital Readout) should show the correct coordinates where the machine position was before exiting Mach3.
- Scroll to the g-code line where the machine stopped. You may need to go a few lines prior to make sure you are not skipping any machining operations (which is why it is a good idea to learn the basics of g-code - don't worry, it's easy)
- Click on the "Run from Here" button.
- Mach3 will present you with a "Preparation Move" dialog box with the location that it will move to. If the coordinates shows a position that is into the material, make sure to specify a rapid height (clearance height) so the machine will move up first and then move to the location before moving down into the material. If the spindle is automatically controlled by Mach3, make sure to check the turn spindle on checkbox. If not, make sure the router or spindle is on before clicking OK.

Additional Information:
My cnc router stops at gcode line 50,000 and cannot finish program. They are about 150k of lines total. I have Mach3 and have bought the additional line capability. Is 50,000 (or around that) the limit? Is Mach 4 hobby license better and in what ways? Thanks! Mike Huber

Additional Information:
If you have a license for Mach3, then you should be able to run g-code indefinitely. I think there is something else going on.

    Currently our machines are made out of MDO (Medium Density Overlay) plywood, and are used in the construction industry for cement forming. They come lightly coated for moisture protection. Some possibilities for protecting the machine could be:
    Painting the structural parts with a oil based paint
    Coating the structural parts with a protectant sealant (polyurethane)

    Please try to avoid getting any coating or paints on the steel components.

  • I am using Windows 10 and my Shopbot PRT 4g uses Shopbot's proprietary software https://www.shopbottools.com/support/control-software. How can I determine if the 4th axis you offer will be compatible with my machine?

    Generally, you’ll need to check what control software will need to be used with the CNC router. Our machines use industry standard electronics and control software that is nonproprietary so you can use just about any software out there with our machines.

    Specifically, what software are you planning on using?

    Additional Information:
    dear Sir,
    I'm searching for the best one,I think that I have to learn more about that in order to be able to make the right decision.

    Additional Information:
    If you are using a computer running Microsoft Windows, then I would recommend using Mach3 or Mach4. If you prefer Linux, then LinuxCNC is the best control software in my opinion.

  • mach3 freezes in the middle of a run, I don't get any message. I have press reset and then the jog buttons work. I have to reset the zero and start from the last line when the machine stopped. It happens mostly during the finishing part of the g-code file

    What interface board are you using? Typically, this will be an issue with the computer that MAch3 is installed. The only other component that may affect this would be the interface between the computer and the machine.

  • Just getting started with building the "Book Machine". I'm looking for feedback from users. Lessons learned, performance etc.

    The greenBull 4x8 is designed specifically for heavy usage with a larger gantry and 3 large NEMA 34 651oz-in motors on each axis. You can expect superior performance from the greenBull since it is specifically designed for every day production of 4x8 sheets of material.

    Additional Information:


    Additional Information:
    The greenBull response was not an answer to my question. I'd still like to hear from users. There must be some suggestions comments from those that have built the machine?

    Additional Information:
    Strange that you got the response matching the greenBull answer. That was probably our automated "closest match". I would re-state the question and select the "no, the answer is not related" and let it hang out on the customer service page for a while to see if you get any bites.

  • How can I decrease the rapid acceleration of the cutter from a completed cutting operation to a new location so that the stepper motor will not lose its steps and mess up the machine zero settings? I am using CamBam and Mach3 on my machine with a chain drive. what is the best way to reduce accleration

    Decreasing the speed of acceleration in the cutter? Meaning of your router/spindle?, To modify the speed of a router will be going to the router itself and modifying the speed, but if a spindle is being used modifying it will be done either manually in the VFD (VFD Setup:
    Change PD001 to '0' (source of run commands)
    Change PD003 to 300 (main frequency - Hz)
    Change PD004 to 300 (base frequency - Hz)
    Change PD005 to 400 (max operating frequency - Hz)
    Change PD006 to 2.5 (intermediate frequency - Hz)
    Change PD008 to 220 (max voltage - V)
    Change PD009 to 15 (intermediate voltage - V)
    Change PD010 to 8 (minimum voltage - V)
    Change PD011 to 100 (frequency lower limit - Hz)
    Change PD142 to 7 (rated motor current - Amps)
    Change PD143 to 2 (motor pole number)
    Change PD144 to 3000 (rated motor revolution))<- make sure these are your settings in the VFD. If the spindle is wired to the breakout board and is working through Mach 3 then the modification will be done in your CamBam/Feed rate settings.

  • I am almost done with the book build Cnc machine, but when I run the motors from mach 3, the 1/2" coupling comes out of the middle spider (the joiner which connects 1/4 and 1/2" coupling. How do I prevent this?

    The lead screw must be held in position axially. In other words, you don't want your lead screw to move back and forth at all. This is the only way the coupling hub that is attached to the end of the lead screw could be moving away from its coupling assembly. Depending on the lead screw that you are using, the combination of bearings and collars/nut keep the lead screw in place.

  • My stepper motors stopped working all of a sudden. Mach 3 is running fine, just no signals getting to the motors. The lights on the motor drivers began blinking erratically when this started. Any advice where a problem like this can come from would be greatly appreciated.

    The drivers have quite a bit of protection, so you probably won't ruin anything. You motors are jumping and that is just the motors engaging from getting power from the power supply.

    There could be many reasons your motors don't turn. Consider these troubleshooting tips:

    - If you are using our parallel breakout board, make sure that the step pins are set for active low (config -> Ports and Pins -> Motor Outputs -> the steps pins should be enabled and set active low)

    - The parallel breakout board is powered (connect the USB to the computer using a USB cable)

    - In Mach3, make sure you have jog enabled (a little green button at thelower middle of the page in the program run screen).

  • Can you preset an origin point on this cnc? How long does it take to jog over? (If I have the case that I using the same thickness of maple wood, and same jig everytime)?

    Yes, you can preset an origin by zeroing the machine at the desired location before beginning your work. You can return to that exact point at any time, or you can specify an offset from that point to be the beginning point for the next machine operation (for instance when cutting several parts from one sheet of wood.) Jogging time varies by machine and application but would generally be a rapid move -- our default rapid setting is 400 inches per minute.

  • Do you offer a touch plate kit? If not can a touch plate kit be added to your machines if so whats the process?

    Yes, you can add a touch plate kit. A touch plate works just like a limit switch. All you need are alligator clips and a conductive plate. Solder a wire to the conductive plate material and connect that to an IN (input) terminal. Connect the alligator clip to the gnd of the input and then to the end mill. Enable the home setting for the Z axis in Mach3 or Mach4 and use the "ref all home" button to home all of the axes. The z axis will home at the touch plate. Make sure that the touch plate is under the end mill when the z-axis is in the homing process.

  • How thick can the material to be engraved will fit inside the BlackTooth machine

    The thickness of material that can be cut or engraved is addressed in other CSL answers.

    The thickness of material that will physically fit into the machine is limited by the distance from the bottom of the cabinet to the laser nozzle, which needs to be at a distance from the workpiece determined by the focal length of the lenses used. (2 inches is standard in our machine.) The standard cabinet of our blackTooth has a cut out section about 25 inches wide designed to allow a sliding tray to be used to easily change workpieces. You could allow for material of any reasonable thickness by adjusting the thickness of this tray so that the surface of your workpiece is the proper distance from the nozzle. You could also modify the cabinet as needed to accommodate special sized work.

    If you need to lase very large workpieces, you might consider our Vertical Laser XL, found here: https://buildyourcnc.com/item/cnc-machine-vertical-laser-xl, or adding a laser tube to the spindle of one of our conventional CNC machines, such as this: https://buildyourcnc.com/Item/cnc-machine-laser-spindle-combo-head.
