across the machine table. Cutting a "live" wire may lead to malfunctions.
Use clamps or another practical and secure way to support the workpiece and secure it to
the machine table. Holding the workpiece with your hands leaves it unstable.
Always turn key-operated switch from the laser controller off before making any
adjustments or attaching any accessories. You may unexpectedly cause the tool to start
leading to serious personal injury.
Visual protection brush must touch the workpiece material during operation to avoid
scattered radiation.
Never bridge the safety system manually on purpose. Use of the laser tool for operations
different from those intended could result in a hazardous situation with high probability of
superficial injury.
Always wear safety goggle when laser tool/system is not covered in an enclosure with laser
light impermeable housing walls and doors. Using personal safety devices and working in
safe environment reduces risk of injury.
This is not a handheld tool. The laser is designed to be system-guided and must be
operated in a CNC router or 3D desktop system. Operation of the laser tool handheld may
result in serious personal injury.
Choose your workpiece carefully before cutting or engraving. It is not allowed to use
mirroring workpieces like metal sheets to avoid scattered laser light that could result in a
hazardous situation with high probability of superficial injury.
The power and feed of the laser tool when carving or cutting is very important, especially
when the material has the ability to burn. Always observe the workpiece material and do not
leave the machine unattended during operation.
If the workpiece or laser head becomes jammed or bogged down, turn the laser tool "OFF"
by the key-operated switch before detaching the laser head. If the key-operated switch to the
laser tool is left "ON" the tool could restart unexpectedly causing serious personal injury.
Do not leave a running tool unattended, turn key-operated switch off and pull out the key.
Only when tool comes to a complete stop and is disconnected from the mans is it safe.
Clean the tool's air vents every 10 hours by using compressed air. Excessive accumulation of
fumes inside the laser head housing may cause combustible deposits.
Do not allow familiarity gained from frequent use of your laser tool to become
commonplace. Always remember that a careless fraction of a second is sufficient to inflict severe
injury.
This product is not intended for use as a medical equipment, in human or veterinary
medical applications. Serious personal injury may result.
Do not alter or misuse tool. Any alteration or modification is a misuse and may result in
serious personal injury.
Safety Rules for System-guided Tools
NOTICE
The laser tool must be controlled by a control software of a CNC router. Therefore, the
power supply of the laser has to be properly connected to the external output of the main
board of the CNC router via a 15-pin D-Sub cable. Prior to each commissioning of the laser tool
the key-operated switch and emergency button functionality has to be checked. Malfunction may
result in serious personal injury.
Do not leave a running CNC system and laser tool unattended, turn key-operated switch
from the laser controller off, pull out the key, turn power off from the CNC router. Only when
a CNC router or laser tool come to a complete stop and are disconnected from the mains are they

FIRE W ARNING
Your laser system uses a high intensity beam of light that can generate extremely high temperatures when it
comes into contact with the material being engraved, marked or cut. Some materials are extremely flammable
and can easily ignite and burst into open flame setting the machine afire. This open flame is very dangerous and
has the potential to destroy not only the machine, but the building in which it is housed.
Experience shows that vector cutting with the laser has the most potential to create an open flame. Many
materials are susceptible to igniting, but acrylic, in all its different forms, has been shown to be especially
flammable when vector cutting with the laser.
Please read the following warnings and recommendations and follow them closely at all times!
2
2.1
-
Stay with the laser. Never operate the laser system while unattended.
-
Clean around the machine and keep the area free of clutter, combustible materials, explosives or volatile
solvents such as acetone, alcohol, or gasoline.
-
Be prepared with a fire extinguisher. Always keep a properly maintained and inspected fire extinguisher
on hand.
-
STEPCRAFT recommends a Halotron fire extinguisher or a multi-purpose dry chemical fire extinguisher.
The Halotron extinguishers offer certain advantages should you ever need to use an extinguisher. The
Halotron extinguisher discharges a clean, easily removable substance that is not harmful to the
mechanics or wiring of the laser system. The dry chemical extinguisher discharges a sticky, corrosive
powder that is very difficult to clean up.
-
Use vacuum assist. Always use the system’s vacuum assist feature when cutting.
-
Use caution when cutting. Many materials have the potential to suddenly burst into flames when cut with
a laser – even materials that may be very familiar to the user. Always monitor the laser head when it is
operating.
-
Clean the laser. A buildup of cutting and engraving residue and debris is dangerous and can create a fire
hazard in its own right. Keep your laser system clean and free of debris. Regularly remove the Vector
Cutting Table to clean any small pieces that have fallen through the grid.

16
NOTICE: If you have a CNC-router from a different brand check the external documentation to connect the
laser to the data output of the specific CNC-router (see also item 7.3)
The controller and the laser head use the voltage supply of the CNC router mainboard (5 Volts). If the mainboard
of the specific CNC router provides more than 5 volts contact the manufacturer.
NOTICE: An additional power supply is not necessary.
NOTICE: Prevent unintentional starting. Ensure the key-operated switch is in the Off-position before
connecting the laser tool to the main board of the CNC router, picking it up or carrying the tool.
After connecting the laser controller turn the key-operated switch in the On-position.
5.4
CNC ROUTER / CONTROL PROGRAM
The laser tool must be controlled by control software of a CNC router. Therefore, the CNC router must be ready
for operation, the CNC control program must be started.
The power and feed of the DL445 is only controlled by the CNC control program. A manual control is not possible.
The CNC control program must start a laser job. Without an active job signal the laser cannot be operated.
5.5
EMERGENCY-STOP SWITCH
The emergency-stop switches are located on the front of the STEPCRAFT 3D system / the individual CNC router
and at the front of the laser controller. Additionally the CNC control software provides software emergency-stop,
too. Pressing either one of the emergency buttons leads to an emergency stop of the machine and the DL445.
The machine will stop immediately. The laser will shut off immediately too.
Actuate the emergency-stop switch only in emergency situations.
NOTICE: Actuating the emergency-stop will result in immediate machine shutdown and can cause step and
data losses.
Controlled cessation of the machine´s operation can only be effected by the control software.
To cancel the emergency stop status, turn the emergency-stop switch to the right. Then the control is re-enabled.
The work process must be restarted.
The entire system is controlled and operated by the PC.
Prior to first usage, read the manual of your control software thoroughly and carefully,
making sure that you have understood everything.
For questions regarding the control software, please contact the respective software developer.
5.6
START A JOB
For this first job you need to prepare a test file for the control software of the router. This program moves the laser
tool within a square (dimension 40 x 40 mm). The operating LED indicator at the front of the laser head
illuminates red when starting the job. End of pass LED indicator is off due to shutdown of the laser diode.
NOTICE: With the power setting of 10% the laser diode will not operate to avoid dangerous situation during this
test job. Regardless the LED indicator indicates an active job.

To start the job the following steps are necessary:
1.
Start the control software of the CNC router / STEPCRAFT Desktop 3D System.
2.
Mount the laser on the tensioning system of the machine.
3.
Start the homing sequence of the CNC router / STEPCRAFT Desktop 3D System.
4.
Clamp workpiece on spoil board on machine table (non-reflective material, ideally wood)
5.
Load the “laser-test.nc” file.
6.
Jog the gantry to the middle position of axis X and Y.
7.
Switch on the DL445 controller with the key-operated switch.
8.
Enable integrated surface sensor (middle positon) to enable positioning laser, position of laser head
approx. 20mm above workpiece to focus positioning laser beam clearly. The positioning laser is a class
2 laser with far less power (comparable to a laser pointer).
9.
Jog the gantry to the effective X Y position and save this position as zero position (X, Y) of the imaginary
workpiece.
18
10. Enable integrated surface sensor (bottom position).
11. Start the tool length measurement procedure in the CNC control program:
WinPC-NC: \ Manual movement \ Move to block – zero-point Z
UCCNC: Specific button on main screen
The laser head moves slowly further down until it reaches the zero position Z.
12. Check the Z height - do corrections if necessary (see section 4.1 or 4.2 regarding the integrated surface
sensor). If not appropriate and the brushes do not touch the workpiece surface slightly, repeat step 11
and 12 after manual movement of the Z-axis to a higher position.
Visual protection brush must touch the workpiece material during operation
to avoid scattered radiation.
13. Disable integrated surface sensor.
14. Start the program, the laser should start, the operating LED indicator on the front of the laser head
illuminates red and the machine drives a square of 40 mm by 40 mm. After completing the square, the
laser turns off (LED off) and the program ends. Now the laser tool is ready to operate.
5.7
TESTING THE LASER EMERGENCY-STOP FUNCTIONALITY
The testing of the emergency-stop functionality is mandatory.
19
NOTICE: Do not use the laser tool if the key-operated and/or internal emergency switch cannot be turned on
and/or off. Any laser tool that cannot be controlled with the switches is dangerous and must be repaired.
The laser tool must be controlled by the control software of a CNC router. Prior to each
commissioning of the laser tool the key-operated switch and emergency button functionality has to
be checked. Malfunction may result in serious personal injury.
For testing the emergency-stop functionality with the control software of the machine or the emergency buttons of
the CNC router or the laser controller simply start the job in section 5.6 again. We recommend doing three passes
to check every emergency button.
During every operation press one of the emergency buttons. The machine must stop immediately and the
operating LED indicator at the front of the laser head must be off (indication of inactivity).
NOTICE: For questions regarding the control software, please contact the respective software developer.
5.8
POWER, FEED AND CYCLE SETTINGS
Depending on the application the operator has at least three parameters to adjust to achieve best cutting or
engraving result possible.
Many applications will provide the best performance at lower feeds with maximum power and multiple cycles but
for certain materials and applications you need to proceed at higher feeds, less power and only one cycles. The
combination of these three parameters are versatile. A laser test run for the specific application is mandatory.
Simply imagine that the residual moisture content in one single sheet of plywood can vary and this already could
influence the laser engraving result significantly.
To aid you in determining the optimum operational feed / power / cycle for different materials, we have compiled a
table. By referring to this table, you can discover the recommended parameters for each type of workpiece
material. Examine this table properly and become familiar with it.
Ultimately, the best way to determine the correct power / feed / cycle adjustments for work on most material, is to
practice on a piece of scrap, even after referring to the chart. You can quickly learn that a slower or faster feed is
more effective, just by observing what happens during processing a pass or two at different feeds. When working
with acrylic, for example, start at a higher rate of feed and lower the speed until you observe that the plastic gets
cut with a nice sharp edge. Secondly try higher feeds again with two or more cycles.
Some rules of thumb in regard to power / feed / cycles / type of material:
1.
Cutting of dark colored material is easier compared to brighter material to higher light absorption.
2.
Material with low melting points typically need less power / cycles.
3.
Engraving must be done in one single pass.
4.
Check the material composition. Every material has its own characteristics and some materials are hard
to cut.
5.
The laser is not intended for and will not cut metals.
6.
When working with thin materials like paper, card stock and vinyl sheet material, a faster feed rate and
lower power will yield better results.
7.
Be careful with some plastics and foams, as they can emit hazardous fumes when the laser beam
makes contact.
If the laser tool is not performing as you think it should, perhaps you should be using an adjustment in power /
feed / cycle setting.

BASIC SETUP FOR THE CAM-CNC PROCESS
6.1
CUTTING (OUTLINE)
-
Load DXF-file with specific outline in a CAM program of your choice
21
-
Define a tool “laser” in the tool library with a diameter of 0.1 mm and an infeed depth per cycle of 0.01
mm. Depending on the workpiece material (see section Power, Feed and Cycle Settings) the specific
power and feed settings have to be done. The parameter “revolution per minute” equals power of laser
diode and should be between 20% (value 20) and 100% (value 100). The parameter “horizontal feed
speed” equals feed of the laser and should be between 1mm and 50mm per second.
-
The quantity of cycles will be calculated by the CAM program automatically with the setting of the
workpiece thickness, e. g. a thickness of 0.04mm equals to 4 cycles of 0.01 mm each cycle.
-
Make sure to set safety and travel heights to zero to keep the laser head down on the workpiece surface
to avoid scattered radiation.
-
Generate the toolpath, save the G-Code created, send to machine control software and start the job.
6.2
ENGRAVING (PICTURE)
-
Before starting the engraving process, you need to calibrate the laser parameters. Each workpiece
material requires different feed and power rates to achieve a reasonable result. Therefore STEPCRAFT
recommends two test scenarios: Black contrast feed test and grey-scale test.
-
The idea behind the black contrast feed test is to evaluate proper black burning on the specific
workpiece material. In this scenario the laser head burns multiple lines with a width of 0.4mm. Each line
is generated with maximum laser beam power and continuous increasing feed rates from 6 to 44mm/s. If
the laser head moves very slow each line will be dark black. As soon as the beam moves faster the
burning color is getting brighter and brighter. The ideal feed for the workpiece material chosen is the
black made with the highest feed possible. The NC-file is available as downloadable file at
<https://www.stepcraft-systems.com/service/black-contrast-feed-test.nc>.
-
After evaluation of the correct feed setting the grey-scale test serves to determine the outcome of
various grey colors by changing the power setting of the laser.
This picture illustrates a perfect result. To evaluate the correct bandwidth of power for the laser beam
and the material chosen a basic test file is available as downloadable NC-file at
<https://www.stepcraft-systems.com/service/grey-scale-test.nc>.
The laser tool generates a test picture of 10 squares, each square with a size of 5 by 5mm. First square
will be burned with 20%, last one with 100% power. You can easily edit the file to your parameters of
choice (jump marker “##”).
-
Load the specific jpeg-file into picture converter like Image2gcode or the UCCNC laser plugin. A well
suited and pretty picture is available as downloadable file at
<https://www.stepcraft-systems.com/service/marilyn.jpg>.
This high-contrast picture with a good mixture of various grey colors can be reproduced easily.
-
Set available parameters. The following parameters should be adjustable to receive a reasonable result:
workpiece width, workpiece height, keep aspect ratio, horizontal or diagonal scan distance, feed rate,
origin point and bandwidth of laser power. You have already evaluated feed rate and bandwidth of
power, all over parameters depending on your personal choice.

most effectively with compressed dry air. Always wear safety googles when cleaning
tools with compressed air.
Make sure to carry out the maintenance/care work every 4 working hours. Depending on the accumulation of
fume, the laser's interior has to be cleaned by gently using of compressed air.
Ventilation openings and switch levers must be kept clean and free of foreign matter. Do not attempt to clean by
inserting pointed objects through openings.
Make sure that no coarse chips and as little dust as possible is entering the ventilation system.
Every three months the fine particulate air filter has to be checked to insure the reduction of the fine dust pollution.
-
Untighten the screws (pos. 14, see section 3) to remove the case cover to check the filter cartridge
24
-
If filter cartridge is black from the side opposite the internal fan and the amount of exhaust air during
operation is little compared to a new fine particulate air filter you have to change the cartridge. The spare
part is available at STEPCRAFT. Please contact your local reseller.
Certain cleaning agents and solvents damage plastic parts and/or the coating. Some of
these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia and household
detergents that contain ammonia.
To continue using the tool in unmaintained condition will permanently damage your tool
