It does have terminals to provide power directly to the board. The one thing I didn’t like about the Cohesion3d LaserBoard is that it uses an external 24V power supply. The LaserBoard also supports the addition of a Z axis table. Such as the ability to add many other options including a rotary setup. The biggest advantage is being able to use any software that can download G-Code to the board. I think the LaserBoard is the best overall. There are other options for controller boards including boards that have adapters for the stock connections. Especially since it works with the K40 variant that I have that uses a ribbon cable for the X axis motor and homing switches. This makes the installation significantly easier. The board is awesome and has all the connections needed to be a drop in replacement for the M2 nano board that came with the K40 originally. The software is also locked and requires a USB key installed while operating it.Īfter searching and reading reviews and specs on various boards I found the Cohesion3D LaserBoard that is based on the Smoothieboard design. The disadvantage of the board is that it only works with the software included which is very old and has limited functionality. Sealed gaps and holes to improve fume extraction.
New internal panel separating electronics section.Focus lens and mirror upgrades to higher quality.Quick disconnects for air and water lines.Blower and fume extraction enhancements.Z Table adjustable platform with larger work area.Air assist for clearing smoke and vapors.In order to improve the functionality I made several modifications. That expanded to include a z-table, improved blower and several other changes. The original plan was to upgrade the electronics and add air assist. Laser Cutting Materials Guide Modifications The following guide is good resource for material recommendations. Some materials produce toxic gas with the laser. Note: Before using a material the laser it is important to know the properties of the material. This is often used for text, photos or vector artwork engraving. Raster image mode allows engraving an image onto the material. It is also possible to do raster images with variable power. The laser is able to cut this depth in a single pass at a slow speed (10mm/s). The edges are very clear compared to using other tools.
In this case I cut two simple 20mm squares to test the calibration. K40 40 watt CO2 Laserīelow is an example of what a cut looks like from 2mm plastic panels. It is a basic limited feature machine usable for cutting or engraving thin plastic or wood. There are a lot of variations with the K40 but most have similar components. The K40 is a 40 watt CO2 laser system that is commonly available on eBay.
