CNC Machines Laser Upgrade Instructions
This part of the documentation is connected with popular CNC machines Laser Upgrades.
Basically, with the help of the PLH3D-CNC Adapter, it is possible to connect the laser head to almost
any CNC machine and turn it into laser engraver. A very important thing besides the connection is G-
Code generating. It differs from the standard G-Code. The laser needs to be switched off during the
idle movement while spindle can be left rotating. The most similar thing in Laser and Spindle G-code
is the power and the rotation speed. PWM signal is controlling the rotation speed of the spindle
while the same signal can be used to control the laser power. Usually, it is done with S0 - S255
command but different CNC Software and Controllers are using different values, for example, S0 -
S1000.

The laser head operator must be aware of laser radiation hazard. While laser head is operating protection Laser Glasses designed for 190 – 540 nm (OD 7+) should be used.
- Page 6 Support a nd Ma nua l s Mounting Setup To mount the PLH3D-6W-Series laser head, the following tools are required: Small flat-head screwdriver; § H2.5 hex key; § H3 hex key; § H4 hex key; § 8 mm spanner; § A few zip ties (optional).
- Page 7 Support a nd Ma nua l s 4. Install the LEAD mount (with a relevant element of the docking station) onto the spindle holder. The LEAD mount is designed to be installed on the left, right, or front side of the spindle holder. ·...
- Page 8 Support a nd Ma nua l s · Use an M5x18mm spacer to be able to install the laser mount without removing the dust shoe (possible only for mounting on the left- and right-hand sides). Mounting the docking station on the left-hand side is the recommended option, because, in this scenario, the laser cable will not face the user.

Support a nd Ma nua l s Wiring Setup 1.Connect one end of the PLH3D-CNC Adapter-to-Laser-Head Cable to the docking station on the LEAD PLH3D Mount. Secure this cable to the mount with a zip tie. 2. Further zip ties can be utilized to fasten the cable at the top of the Z-axis and then along the other side of the X-axis, as shown below: 9 / 26... - Page 10 Support a nd Ma nua l s 3. Next, secure the cable along the X-axis drag chain using zip ties or by putti ng it through it. 4. For the next step, pass the cable around the X-axis motor and then secure the cable along the Y- axis drag chain in a similar fashion as in the previous step.

Page 16: Software Setup
Support a nd Ma nua l s Software Setup To cut or engrave, it is necessary to generate the appropriate G-code using the following commands: Laser ON Laser OFF SXXX PWM duty, where XXX is a number between 0 and 1000 (e.g.: 0 = 0% and 255 = 100%. - Page 17 Support a nd Ma nua l s Setting Working Distance Some engraving applications may require small focus spot, i.e. high-resolution engraving, detailed engraving. PLH3D-6W Series laser head has adjustable focal length and exchangeable lens. This future allows it to fulfill broad range of engraving applications. Shorter focal length of the laser head produces a smaller beam spot (higher power density).
- Page 18 Support a nd Ma nua l s To obtain the highest power density, which results in the better engraving performance, we recommend making fine adjustments to the distance of the laser head and the engraving material. This adjustment should be done after performing coarse adjustment. The process is similar to the coarse adjustment process expect steps in Z-axis, they are smaller to make adjustment precise.
