K40 Middlemen board for Super Gerbil and K40

K40 Middlemen board

To help out connecting a K40 laser machine to a Super Gerbil Controller board, we have created a simple K40 middlemen board.

It is a basic board where we connect the screw terminal connections on the Super Gerbil to the propriety connectors so it becomes just a straight plugin from the K40 via the K40 middlemen board.

Additional axis enables K40 motorised bed height adjustment

Although our Mini Gerbil controller for K40 is selling like hot cakes, some customers need richer features, including motorised bed height adjustment (Z axis).  This is helpful for cutting thicker materials, or for precision management of the laser’s focal point.  The new Super Gerbil controller can easily drive a bed height adjustment motor (as well as the usual X, Y and laser PWM signals), and the new ‘middleman connector’ allows you to easily connect the K40 to the Super Gerbil.

The K40 middlemen board schematic and board are very simple and straight forward see the pictures below.

The ribbon cable will just fit into the FFC connector, ensure the connector lips and receptacle contacts are matching. If you don’t have a ribbon cable than use the 5 pin connector header next to the FFC connector on the right for the limit switch connection and use the X-axis motor connector for the X-axis motor plug. The non-ribbon K40 versions do have their X axis and limit switches spread over two separate connectors which are also available on the middlemen board. If you have a ribbon cable that of course you leave the X-axis header and limit switch header empty.

As you see the K40 middlemen board is very simple and straight forward and we will make this little PCB board available in our web store shortly and a very small price.

Enjoy!
