Time for a serious K40 upgrade ?  This Pro-Pack kit includes:

  • The Mini Gerbil controller, ideal for K40 and other laser cutters/engravers requiring 2 axis and laser control. Throw away your current controller such as Nano M2 and enjoy a smooth experience and higher speed operation. Full installation instructions and support provided.
  • a quality replacement lens, so you get the most from your laser beam
  • a mounting pack that allows you to install adjacent to the original Nano M2 controller if desired.  Or simply install in place of the original Nano M2 controller. Note the product photo shows an acrylic case, but this is no longer included because the mounting pack makes it redundant
  • an exhaust fan upgrade with easy to fit drag chain.  The exhaust fan moves smoke away from the lens, so that it stays clean and your laser beam isn’t filtered by dust particles on the lens.  The drag chain allows you to position the fan exactly where it’s needed most, while keeping the fan’s power cables from interfering with gantry operation.

The Mini Gerbil is compatible with:

  • Inkscape – we’ve built custom add-ins that give you laser control from inside the graphics editor
  • Laserweb
  • Lightburn
  • Easel
  • Other g-code senders

Windows 10 is recommended and supported, earlier versions of Windows are ‘at your own risk’ (we don’t provide technical support).

Mini Gerbil’s dimensions are approx. 80 x 50 x 22 mm.
