After configuring the port settings, you need to save them and restart Mach3 for them to take effect.


Calibrate your machine and set up your work coordinates




The fourth step is to calibrate your machine and set up your work coordinates. Calibrating your machine means making sure that your machine moves accurately and consistently according to your commands. Setting up your work coordinates means defining a reference point and a direction for each axis on your workpiece.


To calibrate your machine, you need to use the calibration feature in Mach3. You can access it by clicking on Config > Set Steps per Unit. You will see a dialog box that asks you to select an axis and enter a distance. You need to select an axis and enter a known distance that you want your machine to move along that axis. For example, if you have a ruler or a caliper that measures 10 cm, you can enter 10 cm as the distance.


Mach3 will then move your machine along that axis by 10 cm and ask you if it moved correctly. You need to measure the actual distance that your machine moved using your ruler or caliper and compare it with the entered distance. If they are not equal, you need to enter the actual distance and click on OK. Mach3 will then calculate the correct steps per unit for that axis and update it in the motor outputs tab.


You need to repeat this process for each axis until they are all calibrated. You can also use a dial indicator or a probe to measure more accurately. You can also use the backlash feature in Mach3 to compensate for any play or slack in your machine's screws or gears.


To set up your work coordinates, you need to use the zeroing feature in Mach3. You can access it by clicking on Zero X, Zero Y, Zero Z buttons on the main screen or by pressing G54-G59 keys on your keyboard. You need to select a point on your workpiece that you want to use as the origin or zero point for each axis. For example, if you want to use the lower left corner of your workpiece as the origin, you need to move your tool to that point.


Mach3 will then set that point as zero for each axis and display it on the DRO (digital readout) section on the main screen. You can also use an edge finder or a touch plate to find the edge or surface of your workpiece more easily. You can also use the offset feature in Mach3 to shift or rotate your work coordinates relative to your machine coordinates.


How to use Mach3 R3 043 066 to create and run CNC projects




Mach3 R3 043 066 is not only a CNC controller software but also a CNC project software. You can use it to create and run CNC projects from start to finish. You can import or design your 2D or 3D model, export or generate your G-code file, load and preview your toolpath, set up and start your machining process, and monitor and control your progress. Here are the steps to use Mach3 R3 043 066 to create and run CNC projects:


Import or design your 2D or 3D model in a CAD software




The first step is to import or design your 2D or 3D model in a CAD software. A CAD software is a software that allows you to create and edit geometric shapes and objects. You can use any CAD software that you are familiar with or prefer, such as AutoCAD, SketchUp, SolidWorks, Fusion 360, etc.


You can import your existing model from another source, such as a file, a scanner, a camera, etc. You can also design your own model from scratch using the tools and features of the CAD software. You can create simple shapes such as circles, rectangles, polygons, etc. or complex shapes such as curves, surfaces, solids, etc.


You need to make sure that your model is suitable for CNC machining. You need to check the dimensions, the scale, the orientation, the resolution, the complexity, the accuracy, etc. of your model. You also need to check for any errors or defects in your model, such as gaps, overlaps, intersections, etc.


You can use the measurement, analysis, and repair tools in the CAD software to check and fix your model. You can also use the simulation and visualization tools in the CAD software to see how your model will look like after machining.


Export your model as a G-code file or use a CAM software to generate one




The next step is to export your model as a G-code file or use a CAM software to generate one. A G-code file is a file that contains the instructions for your CNC machine to follow. It tells your CNC machine how to move the tool along the toolpath to create the shape of your model.


You can export your model as a G-code file directly from the CAD software if it has that option. You need to select the format and settings that are compatible with Mach3 and your CNC machine. You can also use a CAM software to generate a G-code file from your model. A CAM software is a software that allows you to create and edit toolpaths for CNC machining.


You can use any CAM software that you are familiar with or prefer, such as ArtCAM, Aspire, VCarve Pro, Mastercam, etc. You can import your model from the CAD software into the CAM software and then create the toolpath for it. You need to select the type of operation, such as cutting, milling, drilling, engraving, etc., and then select the parameters for it, such as tool type, tool size, tool speed, feed rate, depth of cut, stepover, etc.


You can also modify the toolpath using the tools and features of the CAM software. You can add or delete segments, change directions or angles, adjust the order or sequence, etc. You can also use the simulation and visualization tools in the CAM software to see how the toolpath will look like and how it will affect your model.


After creating the toolpath, you need to export it as a G-code file from the CAM software. You need to select the format and settings that are compatible with Mach3 and your CNC machine. You can also add some comments or notes to your G-code file for reference.


Load your G-code file into Mach3 and preview the toolpath




The third step is to load your G-code file into Mach3 and preview the toolpath. You can load your G-code file into Mach3 by clicking on File > Load GCode or by pressing Alt-L on your keyboard. You need to browse to the folder where you saved your G-code file and select it. Mach3 will then load your G-code file and display it on the code section on the main screen.


You can preview your toolpath by clicking on Toolpath > Regen Toolpath or by pressing Alt-R on your keyboard. Mach3 will then generate and display the toolpath on the toolpath section on the main screen. You can see how the tool will move along the toolpath and how it will create the shape of your model. You can also zoom in or out, rotate, pan, or tilt the toolpath view using the mouse or the buttons on the screen.


You can check for any errors or issues in your toolpath by clicking on Toolpath > Verify Toolpath or by pressing Alt-V on your keyboard. Mach3 will then run a simulation of your toolpath and show you any potential problems such as collisions, overcuts, undercuts, etc. You can also see the estimated time and distance of your toolpath by clicking on Toolpath > Show Stats or by pressing Alt-S on your keyboard.


If you find any errors or issues in your toolpath, you need to go back to your CAD/CAM software and fix them. You can also edit your G-code file within Mach3 using the edit button on the code section. You can also use the MDI (manual data input) mode to enter commands directly into Mach3 without using a G-code file.


Set up your tool, material, and spindle speed




The fourth step is to set up your tool, material, and spindle speed. You need to make sure that you have the right tool for your operation, that you have secured your material on your machine, and that you have adjusted your spindle speed according to your machining parameters.


To set up your tool, you need to select the tool number that matches your G-code file and load it into your machine. You can use the ATC (automatic tool changer) feature in Mach3 if your machine has one. You can also use the manual tool change feature in Mach3 if you need to change the tool manually.


You also need to set up the tool length offset for each tool. The tool length offset is the difference between the length of each tool and a reference length. It affects how deep or shallow your machine will cut or mill. You can use the TLO (tool length offset) feature in Mach3 to measure and enter the tool length offset for each tool. You can also use a touch plate or a probe to measure the tool length offset automatically.


To set up your material, you need to secure your material on your machine using clamps, screws, vices, or other methods. You need to make sure that your material is flat, level, and aligned with your machine's axes. You also need to make sure that your material is large enough and thick enough for your model. You can use the jog mode in Mach3 to move your machine manually and check the position and orientation of your material.


To set up your spindle speed, you need to adjust the speed of your spindle according to your tool type, tool size, material type, feed rate, depth of cut, etc. You can use the SSO (spindle speed override) feature in Mach3 to change the spindle speed manually or automatically. You can also use the PWM (pulse width modulation) or VFD (variable frequency drive) feature in Mach3 to control the spindle speed electronically.


Start the machining process and monitor the progress




The fifth step is to start the machining process and monitor the progress. You need to make sure that everything is ready and safe before you start the machining process. You also need to keep an eye on the machine and the workpiece during the machining process and stop or pause it if necessary.


To start the machining process, you need to click on Cycle Start or press Alt-R on your keyboard. Mach3 will then send the G-code commands to your machine and start moving the tool along the toolpath. You will see the tool movement on the toolpath section and the code section on the main screen. You will also hear and see the machine and the workpiece in action.


To monitor the progress, you need to watch the DRO section and the status bar on the main screen. They will show you the current position, speed, feed rate, spindle speed, etc. of your machine and tool. They will also show you any messages or warnings from Mach3 or your machine. You can also use the MPG (manual pulse generator) or a joystick to control your machine manually if you need to adjust or correct something.


To stop or pause the machining process, you need to click on Stop or press Alt-S on your keyboard. Mach3 will then stop sending commands to your machine and stop moving the tool. You can also click on Feed Hold or press Alt-F on your keyboard to pause the machining process temporarily. You can then resume it by clicking on Cycle Start or pressing Alt-R again.
