Using the 4
th
Axis on the Techno HD Mini Machines
Note: The 4
th
axis on the Techno HD Mini machine is not a true 4
th
axis. You can only use this to
do “wrapping” tool paths. This means that the file is designed as a regular, flat, 3-axis file,
which is scaled so that the width matches the circumference of round stock. Then, instead of
cutting flat, the rotary is substituted for the X-axis and the cut follows the circumference of the
stock, as if it is being “wrapped” around it.
To change from normal 3-axis operation to rotary operation, you must change some settings in
the controller:
1. Press the menu button on the keypad. Go to and press OK to select “5. MFR Param”. The
password is 33587550.
2. Go to and press OK to select “3. Pulse Equiv”. Make note of the X-axis value, it should be
0.005.
3. Calculate the new pulse equivalent value based on the diameter of the cylindrical stock
being used through the following equation:
Rotary Pulse Equivalent = (25.4 * π * D) / 130000
Where D is the diameter of the rotary stock in inches.
4. Enter the calculated value for Rotary Pulse Equivalent in the location for X under Pulse
Equiv. To input a decimal number, please press 0 (zero) first, then the button for the
decimal point and then the numbers.
5. Exit the menu and restart the machine. The new settings will now be applied.
6.
Now jog to your st
arting point and set your X and Y origin. This position should be above the
rotary part. Note: The X-axis
will most likely move at a different speed than normal and the
coordinates will not look right.
7. Flip the switch in the front of the machine into Rotary mode.
8. Run your part
To revert back to normal 3-axis operation, follow the first two steps and then put the original
value, 0.005, into the X-axis pulse equivalent variable, then reboot the machine to apply the
changes.
