This plug and play replacement for the Moshi Board enables you to use the full potential of your 40W machine from Linux / Windows / Mac.
There is a web based frontend that will take vector input (.svg or .dxf) and communicate with the control board.
The software functions correctly without a conversion board (other than actually controlling the machine!). Please download the LasaurApp from the links below. This is the best way to determine if this product is suitable for you.
The voltages inside the Laser Engraver are lethal (240 VAC and 25,000 VDC are present). If you don't know what you are doing, please seek professional advice.
Please download, install and use the software before purchasing.
Verify that either LasaurApp or LaserWeb satisfy your work flow - they are significantly different to the Corel Draw work flow.
