Age Level. This 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.
This section of the program run screen is used to monitor your spindle. This is not that useful if you do not have a controllable spindle speed like most hobby machines.
Pressing F5 on the keyboard has the same effect. This is the main screen you want to monitor in conjunction with keeping an eye on what your tool is doing. You can usually get a good idea that the tool is where it needs to be by checking the axis positions on the readouts. If you have limit switches on your machine and you have them set up as homing switches, you can press this button and your machine will home itself.
Depending on how your software is configured it will move until it locks itself up against the end of each axis travel. It will ignore any soft limits that have been set. You have been warned. You can toggle this to switch between displaying the current position referenced from the home position when lit and from the active offset position. Having it displayed with the active offset position is the most effective option when running a program. Switch this on green light and it activates the soft limit travel boundaries set in the config file.
Toggling this switch will enable you to run the program without the machine moving and switching the spindle on. I have never needed to use this because when you load a program mach3 will run through the program and display any errors that are in the program. This can be very useful when proving out a new program. Pressing 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.
This 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. Activating 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.
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. Simply type G91 G28 X0.
If you need to use the same command again just use the up arrow key and it will display each command you have used in the current session and you can scroll up and pick the one you want to repeat. The rest of the MDI screen contains a lot of the information and options shown in the Program Run screen.
These buttons can be used to record your individual lines of code in mdi to create a small program. This function could be used to create a quick facing program to clean up a blank piece of stock. You could manually jog the spindle over your workpiece making a note of the positions you need, then recording them in MDI using the teach function to make the program.
The toolpath screen is very similar to the program run screen but has a much larger toolpath display. This is super useful for checking your toolpath closely, especially if it is quite large and complex.
Any issues will be easier to see with the larger display. The offsets screen is where you will set and store all the positions that are needed to enable the machine to locate your part accurately. Using an edge finder or dial to locate the stock on your machine and set the values in the offset tables. 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 area of the offsets page is used when picking up a workpiece with an edge finder.
The dia of the edge finder is entered into the box, in this case 0. The edge finder is then touched against the edge of the workpiece. The software will set the active offset to that position taking into account the diameter of the edge finder. This is a more convenient than making a note of the machine offset position and manually typing it into the offset table. Using this sets the Z value of your active offset. Type in the height of the block you are using to touch off your tool or spindle and the software will account for it in its calculation.
Using this is similar to the set Z option except it will calculate the tool length of the tool you are setting using the current active Z offset. Touch off the tool and it will measure the difference of its current position against the set Z offset and it will be entered into the tool offset table. Again, it will take into account the height of the block you are using, as long as you entered it correctly. Selecting one of these will display the associated table, enabling you to directly input or adjust any of your offsets.
Choosing the save tool offsets will enable you to change the diameter of your tool so you can adjust your part dimensions when using a tool dia offset in your programs, e. G41 or G 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. 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.
The distance moved is dictated by the cycle jog step button. Pressing the cycle jog step button will toggle through preset distances. These are 0. The step mode is used for touching off an edge finder or accurately locating a dial to pick up a part when setting your datums. These are pretty much plug and play and you will wonder how you managed without one after using it for a short time.
Looking at the screens, if there is a keyboard hotkey for that button it will show it on the button. The arrow keys can be used to jog the machine in the X and Y axes, with the page up and page down used for the Z axis. For some functions such as cycle start, the keyboard shortcut requires two keys to be pressed. This provides some built in safety, meaning the machine is unlikely to start operating if you accidently lean on the keyboard.
One thing to note, the shortcuts are displayed as capitals, you do not have to use caps lock, a lowercase letter works. Once it was setup for my machine it has never crashed and caused any issues. I would recommend it to anyone wanting a hobby cnc machine, the only choice you should have is what type of cnc machine to run it with. I also have a tutorial for Candle Grbl software , which is a free download.
