In Mach4, you need to calibrate your axes so that real-world measurements are the same as the measurements for your axes' position.

Mach4 has a wizard that allows you to calculate the steps per unit for an axis. This is a manual operation, so you will need to use the existing steps per unit in the axis you wish to change.

Go to motor tuning to grab this number and copy it to the clipboard. Now go to the wizards menu and "select wizard". Scroll through the wizards until you see "StepsPerUnitCalculator" wizard and accept that wizard.

A new dialog box will appear with fields that you can use to determine the new steps per unit for the desired axis. The incremental move button is available so you can test new values calculated for the steps per unit for the axis. Use the "move distance" along with the "move velocity" to incrementally move to determine move distances.

To connect an emergency stop (e-stop) to the Mach3 USB controller, use the emergency stop switch/button on the NO (normally open) connections of the switch. Connect one side of the NO connection to IN1 and the other side of the NO connection to the DCM, or GND (V-) of the 24V power supply that is used to power the Mach3 USB controller.

In Mach3, go to the Settings Tab, and select "Set Steps Per Unit". It will ask you how far to move the machine. Before you do this, make a mark on the table exactly where the end mill is resting. You can do this by lowering the end mill until it touches the material, then spinning it by hand to cut a small dimple in the material. Then, raise the end mill to clear the material, and assign a distance to move the machine. Once the machine moves and stops, measure the exact distance that it actually traveled with a tape measure, and enter this value into the dialog box that asks how far it moved. Mach3 will automatically adjust your steps per unit for that axis to be more accurate. Do this for all axes often to ensure you are cutting accurately. The longer distances you use calibrate, and the more precise you are with your measurements, the better.

MY MACHINE CUTTING THE WRONG SIZE PART

Dealing with our USB BoB, the potentiometer that will be used in the key jog, is a 5V, 5k - 10k Ohm potentiometer.

Click the link to add information to this solution:
I am building a cnc mill using your USB controller and i would like to know what is the specification of potentiometer used for adjusting manual axis jog speed

LinuxCNC has excellent documents; however, I would like to offer our help in case you don't understand the information on that page. So, please use this FAQ (Question #: 13233) to state your questions by submitting additional information below.

The LinuxCNC spindle control page is found here: http://linuxcnc.org/docs/html/examples/spindle.html

Additional Information:
After reading the LinuxCNC page my first questions would be can the spindle be controlled by PWM signal? Also, what pin on the parallel port would I set to Spindle Enable and FRW?

Additional Information:
To connect your computer to the VFD, use a USB to RS-485 interface. RS-485 is just a serial interface protocol that uses standard 0 to +5 voltage TTL signal levels for communication (as opposed to RS-232 which uses -12v and +12 for signal level changes).

Get a high quality interface to reduce any issues during the process. The VFD should have two terminals labeled RS+ and RS-. The USB to RS-485 adapter should have this labeled on it as well so the connections should be relatively straight forward.

In the VFD parameters:
PD001: 2 to accept RS485 commands
PD002: 2 to accept frequency comands
PD163: 1 to RS485 slave address:1
PD164: 1 RS485 baud rate 9600
PD165: 3 8bit, no parity, 1 stop bit

Make sure LinuxCNC is also set accordingly:

The PIN14 and PIN16 in the stepconf wizard should be set to unused because you don't want LinuxCNC to be outputting unnecessary signals.

In the options step of the stepconf wizard:
- Check the Include Halui user interface component.
- Check the Include custom PyVCP GUI panel.
- Check Spindle speed display

You will want to edit the custom.hal text file located in the folder that was created from the stepconf wizard. Add these following lines:
loadusr -Wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600
net spindle-cmd-rpm-abs => vfd.speed-command
net spindle-cw motion.spindle-forward => vfd.spindle-forward
net spindle-ccw motion.spindle-reverse => vfd.spindle-reverse
net on motion.spindle-on => vfd.spindle-on

The dev folder in linux is typically used for interfacing devices and peripherals to the computer as these devices are communicated by simple memory addresses and these files are linked directly to these addresses.

Under the custom_postgui.hal file, change this line:

from: sets spindle-at-speed true
to: net spindle-at-speed => cfd.spindle_at_speed

and add the line:

setp vfd.enable 1

When you start LinuxCNC, you will a spindle section with the reverse and forward buttons, a stop button and - and + buttons. Use these buttons to conform that the spindle is functioning properly. The spindle speed indicator in LinuxCNC will show the spindle speed and you can confirm that this is equal to the speed indicated on the VFD.

Yes, we can design and produce custom CNC routers. You will need to contact us to discuss the customization that you would like.

WHAT SIZE COLLET IS IN YOUR 1.5 KILOWATT SPINDLE?

There are several CAD/CAM programs out there for MacOS. Here is a list of a few: http://www.macuser.de/forum/f53/3d-2d-cad-395058/#post4499316
I've also read good things about punchCAD: http://www.punchcad.com/
Of course, there is always SketchUp if you are in a pinch. There are a few CAM plugins for SketchUp as well, but I've never used them, so I can't vouch for them.

CAD/CAM will get you as far as designing your parts and producing the g-code, but if you also want to run the CNC machine with your Mac, you will need a piece of software similar to Mach3 or EMC to run the g-code. I haven't been able to find anything like these programs that runs on Mac, so you may have to run Mach3 or EMC in Windows using Boot Camp or a virtual machine such as VMware or Parallels.

Personally, I would use the Mac to do all the CAD/CAM, then use a cheap PC to run the CNC machine.
