General Information
The optical engraver is connected to a Raspberry PI 3 Model B with Raspbian Jessie running version 3.256.0 of LaserWeb3.
- multicast address: laserweb.local
- IPv4: 192.168.110.176 (not guaranteed to be the same)
- LaserWeb is listening on port 8000
Steps to engrave/cut an SVG:
Please note that currently the Y axis of the engraver is inverted. This results in mirrored engravings. Flip the SVG horizontally to fix this.
Preparig the Machine
- Make sure the power is turned on both in the extension cords and in the machine itself
- Install the workpiece and close the lid
- Turn the laser on (green button, check that the red led turns on)
- Turn on the lights (flip the small metallic switch)
- Check that the laser power is set at an appropriate level
Engraving the SVG
- Browse to http://192.168.110.176:8000 or http://laserweb.local:8000
- Click the Open button and select an SVG image or drag-and-drop it
- Configure the feedrate, number of passes and depth of each pass
- Click the Generate G-Code button
- Click the Process button to load the G-Code
- Click the run gcode (Play) button to run the G-Code
- After the machine is idle, click the home laser button to return the laser home
Installing the Workpiece
- If possible, use the clamps. The laser focus seems to be good at the depth of the clamp.
- The maximum height of an object that fits the clamp is roughly 80mm.
- If engraving larger pieces, make sure that they stay still and don't move. A few drops of superglue should hold them still.
Observations on Cutting Depths
6mm acrylic
| Feedrate | Laser Current | Passes | Cut depth observations |
|---|---|---|---|
| 20mm | 5mA | 10 | Barely a scratch, might work for engravings |
| 20mm | 10mA | 5 | About the same as 5mW x 10 |
| 20mm | 15mA | 5 | Roughly half a millimeter |
| 20mm | 20mA | 5 | Roughly half a millimeter |
| 20mm | 20mA | 30 | Around 2-3mm, acrylic started to melt |
| 40mm | 20mA | 30 | Around 2-3mm, clean cut |
4mm acrylic
40mm feedrate with full power (20mA) took about 60 passes to cut through 4mm acrylic.
Debugging
If the engraver doesn't seem to be connected to LaserWeb, try reconnecting the USB cable to the engraver and then reload the web page.
