WARNING: IMPROPER OR UNSAFE OPERATION OF THE MACHINE WILL
RESULT IN PERSONAL INJURY AND/OR DAMAGE TO THE EQUIPMENT.
READ THESE INSTRUCTIONS THOROUGHLY BEFORE OPERATING MACHINE. DO NOT OPERATE
MACHINE IF YOU ARE UNFAMILIAR WITH THESE SAFE OPERATING INSTRUCTIONS. DO NOT
OPERATE MACHINE WITHOUT KNOWING WHERE THE EMERGENCY STOP SWITCH IS LOCATED.
PREVENT FIRE HAZARDS by using the proper feeds, speeds, and tooling while operating your
Techno machine. For example, setting feeds and speeds too low and/or using dull tool bits creates
friction at the material. The friction generates heat which can result in a re that can be drawn
through the vacuum table or dust collector without warning. Fire hazard from friction heating
caused by dull tools is possible when cutting certain materials, especially composite material
such as wood composites, MDF and Particleboard. © 2015

3.5- Adjusting the XYZ Zero position/WCS/User Origin.
XYZ zero position, Working Coordinate System (WCS), and
User Origin are all the same thing.
Different CAM systems and users just name the concept
differently. For convenience XYZ zero position will be used in
the rest of this manual.
XYZ zero position is the location point on a drawing in a
CAD/CAM package where X,Y and Z all equal zero.
Generally, XY zero is on the bottom left corner and Z zero
is the top of the part. In fig 3.3a the letters are located
away from the XY zero, all points representing positive
integers.
In Fig 3.3b the object represents the material the letters will
be cut from. The machine should be jogged to the corner of
the material by using the directional arrows on the keypad.
Once the machine is in location press to set XY zero. The X
and Y coordinates wil now read 0.000.
XY zero is now set.
Fig.3.3b
Fig. 3.3a
There is one method for setting the Z-axis zero position:
Use the Z-axis directional arrows on the keypad to move
the router to the top of the material. Switch to Step Mode to
slowly move the machine into position. When the router bit
is in position press shift/aux and the Z=0 button as shown.
The Z coordinate will now read ‘Z 0.000’

Notes On the G-code File
If a part requires multiple tools, it is best to output a dierent le for each part.
If the G-code le references a tool number higher than T10, then the controller will
give an error at the start of the le. M6 T1 to M6 T10 are allowed.
In general it is best to remove T commands by telling the CAM package that the
machine is not a tool changer machine, or insuring that the Tool number does not
exceed 10.
G92 is the Axis presetting command, when this command is encountered in the
G-code le the XYZ zero position is set at the position the machine is in at that time.
In general it is best to remove this from the G-code le, or if it is in the G-code le,
make sure the machine is at the origin before you press start.
The controller will recognise G54 to G59 oset commands.
See the NK105 G2 manual for more details on these commands.
Acceleration Set
Under the menu MFR Params, there is a sub menu called Velocity.
This menu controls the acceleration and cutting motion of the machine.
The Defaults for these parameters are:
Jerk 310
Single Axis Acc 25
Max Turn Acc 100
A low Max Turn Acc will result in arcs that move in a jerky motion or at a slow speed.
Pulse Equiv (scale factors)

Using the 4th Axis on the Techno BT1212 Machines
Note: The 4th axis on the Techno BT1212 machine is not a true 4th 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 Y-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 Y-axis value, it should be
.00125.
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) / 20,000
Where D is the diameter of the rotary stock in inches.
4. Enter the calculated value for Rotary Pulse Equivalent in the location for Y 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 starting point and set your X and Y origin. This position should be above the
rotary part. Note: The Y-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, .00125, into the Y-axis pulse equivalent variable, then reboot the machine to apply the
changes.
