Figures 24 and 25. At this point, it is probably best to
remove power from the controller by unplugging the AC
power from the power supply.
We will be using Mach3
software to control our CNC. The
software is free as long as you use
less than 500 lines of Gcode. You
can download a copy from
The first step is to download
the software and install it. If you
are using a parallel port, be sure
to install the parallel port driver. If
you are going to use a
SmoothStepper, don’t install the
parallel port driver.
I have created three files that
will help you get your KReduCNC
up and running with very little
effort. They consist of the
These can be downloaded
from the KReduCNC support
pages. Place the
KReduCNC.xml files in your
Mach3 install directory. Place
the KReduCNC.lnk on your
desktop, as it is the shortcut to
start Mach3 with the correct configuration file.
Let’s start by making sure
each axis is connected properly.
With your motors connected as
outlined earlier, power up your
controller power supply and PC.
Start Mach 3 by clicking on the
shortcut provided. You will be
presented with the startup screen
shown in Figure 26. Observe the
Reset button in the lower left of
the window. When first started,
this button will be flashing red
and green. This tells you that your
machine is in reset mode. Hit the
button; it should turn to a solid
green as in Figure 27.
Now, with the Mach 3
window in focus, hit the right
arrow on your keyboard (Figure
28). Your X carriage should move
to the right. If the carriage moves
to the left, you will need to power-down your controller power supply
and reverse the X axis
Repeat the process with
the Y axis by hitting the down
arrow (Figure 29). The table
should move towards the back.
This may seem reversed at first,
but it is from the perspective of
the bit in reference to the table
so just accept it at this point.
Again, if it does not, reverse the
Remember to remove the
power before doing so. Next,
