Mach3 Mill Tutorial
Deidamia Bassiti
Mach3 is a popular Cnc control software that is available for download to use on windows computers. This makes it an ideal option for the D.I.Y. Cnc enthusiast to control a small milling machine or router.Will mach3 run on windows 10?Mach3 will run on windows 10. I have been using windows 10 for a while and I have had no issues.
However there are a few quirks that will be different to other cnc control software.Hopefully the following tutorial will answer a lot of questions you may have about using it to run your Cnc Machine.
It then prompts you to manually position the spindle in the correct position so it can continue. This will not work if you are using a subroutine or sub program though.You have been warned.RewindThis button is used to get the prompt back to the beginning of your program. This is not used while the program is active.
Again this is a toggle switch to turn the function on and off.With it switched on the machine will stop at a M01 command, basically turning it into a M00 stop command.Switched off it will ignore the M01 and continue on with the program.
This needs to be on to enable you to move the machine manually with the jog function.Feed RateThis section of the program run screen displays the current feedrate. It also gives you the ability to change the feed while you are running a program. Using the arrow keys can speed it up or slow it down.It will display the current speed and percentage of the current feed compared to the programmed feed.
It can enable you to see any potential collisions before they happen.Zero X, Zero Y, Zero Z and Zero 4Pressing any of these will zero the axis of the currently active offset. These can be used as a kind of shortcut to zero your offsets when setting up a part.The display box on each axis is also clickable. You can type in the window any distance you want and it will adjust the active offset.
Not sure this is a good habit to get into though, any changes should be done on the offset page to keep your process as simple as possible.Toolpath WindowThis is where the toolpath will draw when you load a program. It will display it initially from above, which is showing X Y view.If you double click with your mouse inside of the window it will show an orthographic view so you can see X, Y and Z movements.
You can also left click, hold and move your mouse to rotate the view. Right click, hold and moving the mouse will move the toolpath. If you have a wheel on your mouse you can use it to zoom. Alternatively you can shift-left click and drag the mouse to zoom in and out.The toolpath display is pretty basic, it is there mainly to confirm that the program will run correctly and the software can send the program to your cnc machine.If you wanted to analyse your toolpaths in more detail you will need to use a G code simulator. I review a couple of free cnc simulators in my G Code Simulator article.
Click this and the tool path window graphic will be regenerated.Display ModeActivating this toggle switch will display a dotted rectangle in the toolpath window. This rectangle represents the soft limit boundary you set in your config file for use with the soft limits function.This is extremely useful for confirming that the program you have loaded will not hit the limits of your machines travel.
Checking this option will force the display window to follow the position of the tool as it moves. In other words the tool position will be fixed in the middle of the display.MDIMDI is an acronym for Manual Data Input. It enables just one line of code to be input and executed. It is a quick way to move your machine, switch on the spindle or activate an offset etc.I find it useful for homing the machine after setting the datum on the piece I am currently working on.
This area of the offsets screen shows you which offset is active and what the offset values are. You can choose to display the six main offsets, G54 to G59, shown in the table as Fixture 1 to Fixture 6.Whatever offset you select here will not affect which offset is used in a program, this is dictated by the G code in the program you are running.This table can be used to select an offset for executing a line of code in MDI, for example.
This is used to manually move the axes. This function is most commonly used when setting the datums of your current project.The most used buttons are the green and red jog buttons at the bottom of the MPG screen. Pressing any of these will move your machine in the displayed axis direction. The jog rate can be changed by changing the percentage value above the jog buttons.One useful function is pressing shift when using the jog buttons. This will force the machine to jog at 100% regardless of what percentage the jog is set at.
Pressing this button with your mouse toggles through three options, cont, step and MPG.Cont stands for continuous and enables you to move your axes continuously, just press a direction button and your machine will move.Toggling the jog mode button to step gives you the ability to move your axes in controlled distances.
This video should provide enough guidance to understand the PWM signal on the Mach3 USB controller:
The PWM signal is provided by the AVI terminal, and the 10V terminal is an input and provides the reference for the top voltage for the PWM signal. The ACM is the analog common (analog ground)

[575] Hello, I'm wondering if you can provide advice how to wire this USB board where for spindle I would like to use chinese servo motor and driver (TD3) - speed control mode. Especially how to connect - AVI, ACM and 10V (24V is clear). I am still not sure how to power on and off spindle itself. Thank you in advance. Vaclav
This controller does not have an encoder input for the spindle. The controller can output a PWM signal which causes the spindle VFD to spin at a specific RPM. That RPM is shown in Mach3 as long as the configuration has been applied properly. You can also calibrate the RPM of the spindle to match the RPM shown in Mach3 with the use of a tachometer and adjust the configuration in Mach3.
This was true for controllers that use the parallel port to communicate with the CNC as the CPU is sending signals to each of the parallel port pins (GPIO or General Purpose Input/Output). With newer types of controllers that use the USB connection, this is not a problem anymore since all of the signal processing happens on the controller rather than in the computer. The computer only needs to send high-level commands to the controller and the controller translates the simple commands to pulse trains that the drivers can accept.
Additional Information:
I don't believe that the board itself buffers. MAch3 however, does use an algorithm for look-ahead.

Thank you for the information. I plan to use a second SSD with a minimal Windows 10 or 11 system.

[575] Buffering. In former days, I used a MS DOS application to do the milling jobs. I was told that Windows sometimes does other jobs ans so my milling job would be ruined. Does this USB board buffer some of the CNC data to circumvent such errors?
Unfortunately, all of the attemps I have made to use this controller with a THC did not work, so I would not recommend this board for plasma machines that use a THC. THe Pokeys57CNC controller will work with several THC controllers. I have used the Proma and the PlasmaSens controllers with the Pokeys57CNC.
The Mach3 USB controller does not contain an onboard relay; however, you can use the output to control an external relay. Follow this tutorial to control an external relay on this controller:
Make sure the output port is set to port 3. I did not mention this in the tutorial.

You can adapt the Mach3 USB controller to control a laser, but I would not recommend it. A traditional laser controller that is designed to control a laser is far better since you can take advantage of more sophisticated features like sweep for engraving, and automatic adjustment of laser intensity for acceleration and deceleration. The Mach3 USB controller can move the axes and turn the laser on and off, but intensity control and engraving are not an option.
Yes, the Mach3 USB controller will work with the latest Windows version and in 64-bit mode. The 32-bit mode is only relevant for using the parallel port driver if you are using a parallel port breakout board. Since this controller is connected via a USB cable, the 64-bit state will work fine.

You should not have a problem with using this controller and having more than 500 lines of GCode. The 500-lines limitation is specific to licensing. Make sure that the Mach3 that you are using does not show "Demo" at the top of the screen. You can also confirm this in the help->about. If you are using a license that was purchased through this website, or from Machsupport.com, you should be fine.

i have a licence but mach 3 not work above the 500 lines

[575] Although i have licensed mach, when i use that particular board it seems to run only 500 lines of code, how can i fix that? i
