Need help? Our chatbot has already read the manual and is ready to assist you. Feel free to ask any questions about the device, but providing details will make the conversation more productive.
This manual assumes that you have already followed the instructions in your installation Manual, hooked your CNC Router to your power supply and computer and installed your Mach3 Software. If you have not, please do so before proceeding. Also keep in mind that much of this information is covered in the Mach tutorial videos which can be found at http://www.machsupport.com
A few things to check before you get started:
-Make sure that your parallel cord is connected securely to your computer and to the Router.
-Make sure that your E-Stop button is not engaged.
-Make sure that all 3 (even the switch that doesn’t light up) power buttons on the router control box are
ON.
You should have already received an e-mail containing two files. From that e-mail save the .xml file
(machine configuration) and .dat file (license for the Mach Software) to your desktop.
Drag or copy these files into your main Mach 3 Folder. If you don’t know where this is, right click on your
Windows Start button, choose “Explore”, you will see the folder “MACH 3” under your C Drive (unless you chose another location during installation.)
Do not adjust the buttons on the control box touch-pad. This may reprogram your inverter so that it is no longer controlled by the Mach Software. The only feature you will use is the dial which controls your spindle speed.
Open the software from the desktop icon Mach 3 Loader. Select the name of the file you were e-mailed
(usually Mach3mill.xml) Click Open. The Main Mach 3 screen should open up and the profile name should appear in the bottom right of your Mach Screen.
If the Reset Button is Flashing. Press it once. All commands are disabled when this is flashing. This will also function as an E-Stop button.
Jogging
You can move the spindle manually using the arrow keys on your keyboard. This is called Jogging.
Jog Speeds and settings can be changed by hitting your Tab key once. (Hit the Tab Key again to put the setting screen away.)
Left and Right move the spindle Left and Right (X axis)
Up and Down Arrows move forwards and backwards (Y axis)
Page Up and Page Down keys move the spindle Up and Down (Z axis)
Slow jog is the movement caused by simply hitting the direction buttons.
Fast Jog is the speed obtained by hitting your Shift Key at the same time as your arrow keys.
You can track the movement of your Spindle using the Digital Read Out Numbers. You’ll notice there is a box for each axis, X, Y and Z.

Homing/Limits
This section deals with setting your Machine Coordinates. Machine Coordinates are the overall dimensions of your table. These coordinates allow you to set up Soft Limits which will keep your machine from running into the ends.
Select CONFIG from the top menu bar
Select Homing/Limits from the Drop Down Menu
Enter in the dimensions of your table:
Ex. 5 x 10ft. table with 7.5 inch vertical motion
In this example the X axis starts at Zero and ends at 60 inches. This means you have 60 inches of workable area from Left to Right.
The Y axis has 120 inches of travel area from front to back.
Note that the Z axis is a negative number. That’s because most people home the Z axis at the top of the spindle because the dimension at the bottom can change depending on thickness of material, depth of cut, etc. So your maximum cutting depth is 7.5 inches in this illustration. Note that this is different than setting a home for a specific job which we will cover later.
Your machine now believes that these are the table dimensions. It will not yet stop you from exceeding them however. This is done by Limit Switches or using your Soft Limits.
Setting Limits
Your router is equipped with limit switches designed to stop your machine from running past workable area and possibly damaging the machine or causing injury. We will refer to these switches as Hard
Limits.
We do not recommend using this method to stop your machine as the switches wear every time they are used and as a result do not stay reliable over time. Should you decide you want to use this method, you can activate or deactivate the switches by choosing Ports and Pins from the “Config” drop down
Menu.
This box below will appear:
Select the tab Input Signals
Note that these switches are not enabled. If you choose to enable them you can find more information on the process by watching the tutorial video at Mach’s website.
We recommend using the Soft Limits to stop your machine. This is a much easier and productive way of establishing your safe limits.
In order to do this you must first establish your Machine Coordinates. We already set the dimensions in the Homing/Limits Section. Now we need to make sure the machine recognizes them.
First Jog your spindle to what we will call it’s “Home Position” You will want to do this for each of the three axes.
For the Y axis bring the spindle all the way to the front (the side with the control box) You may want to bring your spindle down to ensure that you are at the limit of your cutting area as the Y axis can pass the end of the table and hang in the air.
For the X axis bring the spindle as far to the left as it will go.
For the Z axis, send the spindle all the way up to it’s top position.
Now, on the main screen, select the Box marked Machine Coordinates
Not Selected Selected
With the Machine Coordinates button selected, select the vertical button (to the left of the DRO) marked REF ALL HOME
This will reset all DRO’s to Zero. This is now your “Machine Coordinates Home.” Now Select the Button,
Soft Limits. When Selected it will be outlined in Green
Your soft limits are now activated.
Next, Deselect the Machine Coordinates button, so it is no longer bordered with Red. This will keep you from changing the Machine Coordinates accidentally, at which point your Soft Limits would no longer be effective or accurate.
(Please note that your Soft Limits will not engage if you are outside the limit area for any axis. If it will not engage, make sure that your homing/limits screen is set accurately.)
If they fail to activate, Turn on your Machine Coordinates, jog the spindle from 0 to the maximum distance away from zero (for each axis) Note the DRO for each axis at it’s far limit. If the DRO shows a number higher than you set in the Homing Limits Section. You will need to adjust your “Motor Tuning”
Motor Tuning
To make sure that your machine is actually travelling the distance it says it is in the DRO’s, you may need to adjust the Motor Tuning. Each axis has its own motor (two for the Y axis although you will treat them as one) and should each be checked. To check Your Motor Tuning select it from the CONFIG drop down menu. The following are some typical settings for each axis, although some variation is possible, depending on your model and options.
The most important box is “Steps Per” This signifies the number of steps the motor must take to travel one unit (inch, MM.) The only way to measure this is to track the DRO’s as the spindle travels. You can do this manually or using a digital gauge.
Simply put, you can jog the spindle 12 inches on an axis according to the DRO and then take your own measurement of the distance travelled with a ruler or tape measure. If using a digital gauge just record the actual distance. If the DRO is higher than it should be, change the number in the “Steps Per” box to a lower number. If too low set to a higher number until your DRO is accurate. Once set accurately, the
“steps per” should not need to be changed. If you want to keep a change in Motor Tuning you must select Save Axis Settings, before leaving the screen.
Mach 3 has an automatic function to help with this. On Your Settings Screen. Click the Set Steps Per Unit
Button. Select the axis you wish to calibrate. You will then be asked how far you wish the axis to move.
Once you enter this value Mach will make the machine move what it thinks is the requested distance. It will then ask how far the axis moved. Measure the actual travel and enter it into the box. Mach will then suggest a steps per number to correct this, which you can accept or not.
You can also change the speed of your Router through Motor Tuning, using the Velocity and
Acceleration sliders.
Velocity is the speed your spindle will attempt to reach and maintain. Keep in mind that while you can set this extremely high, it is not always beneficial. For small and intricate detail work and sharp corners, running too fast may cause your router to skip or cut improperly. It’s usually better to start slow and work up to a speed your comfortable with. Conversely on a job consisting of large circles you without sudden starts and stops, you may want to take advantage of all the speed you can get!
Move the Velocity tab up and down to change the speed.
Acceleration is the rate at which your Spindle approaches its set Velocity. If it makes jerky motions on corners or seems to lag, the acceleration may be too high or low. Adjust this by moving the slider Left and Right.
The speed your spindle travels can also be set by changing the Feed Rate in your Post Processing
Program. This can then be adjusted lower using Feed Rate Over Ride (Your Feedrate will not however, go higher than the speed you set.)
Spindle Operation
Your spindle may be turned on and off through your Mach 3 Software using the Spindle CW F5 button.
The speed of the spindle turning is controlled by the dial on the Router Control Box. Maximum speed is
24,000 RPM, which reads 400 on the Control Box DRO. 12,000 RPM is 200 on the control box, and so on.
When the Spindle is on the Button Border will flash yellow.
Your machine is now ready to cut!
Setting Job Coordinates
The second type of coordinates are Job Coordinates. Unlike Machine Coordinates which you want to leave the same at all times, Job Coordinates can be changed with every job.
Rather than homing your Z axis at the top, you may want to Zero your Z axis right at the surface of your work material, rather than having your bit descend all the way down before it cuts.
You can zero the axes anywhere you like on the table, by simply pressing the button to the left of each axis’ DRO once the router is at the desired position.
When your job has finished, you can return the bit to it’s Job Coordinate Home by pressing the “Go to Z” button (next to the Machine Coordinates Button)
You do not need to change each axis for every job. If you are happy with the depth of your cut (Z) and it’s front to back position (Y) but would like to move the job 2 inches to the right, this can be accomplished by using “Go TO Z” and then moving the X axis two inches to the right.
Trouble Shooting
Spindle spins the wrong way.
The wires running from the spindle to the inverter are reversed.
One Y motor is running the wrong way.
You have reversed two wires in your Y Driver. Consult your wiring diagram.
One Y motor is not running at all.
Check and see if both the Y and YY drivers are working. This can be done by switching their wiring. (If the driver on the opposite side stops working it may be the driver)
Spindle does not reach the table top (or work surface)
Loosen the bolts on the spindle cover, which will allow your Spindle to drop to desired height. Retighten once in place.
