MyDIYCNC Sprite CNC Machine Kit
Do It Myself
In an effort to put the power of machining in the hands of the people, MyDIYCNC set out to create a CNC Machine assembly kit that could be easily put together and deliver reliably high function. With several entry points, compatibility with most common CNC apps, and configurability to accommodate a range of spindle options as well as milling, cutting, engraving, and laser etching, the MyDIYCNC Sprite CNC Machine Kit is a versatile CNC Machine that can be assembled with minimal electronic or construction skills.
Make the Cut
This is a cutting machine, and it uses a spindle (rotary tool) as the primary cutting tool, which means you must be substantially more careful than with a filament printer. On the new and improved kit, the parts are precision CNC-milled aluminum, the spindle mounts have been improved, and the spindle itself now incorporates a ball bearing shaft, speed adjustment, a built-in cooling fan, and a keyless three-jaw chuck. Once constructed, the CNC Machine connects to your PC through a third party CNC software application, or through your USB port with the optional USB solution.
Power-Ups
At checkout, you’ll have several options to choose from. The base Sprite CNC Machine comes with the HiTorque Spindle upgrade included, and the set can be purchased either as a DIY Kit or as a fully assembled Turnkey Machine. Additionally, you can select the follow options as add-ons: the Laser Head Kit (445 nm, 1.7 W blue laser) to add laser etching and thin material cutting capabilities; the MyDIYCNC Limit Switches Kit to add limit switches, with some soldering and drilling required; Parallel Port Cable (25-pin D-type Male-to-Female straight through cable) to connect the system to your PC; the PC PCI Parallel Port Add-in Card to add a Parallel Port interface to your PC; and the MyDIYCNC USB Solution (including interface, cable, and FabCAM) to make your CNC Machine USB-controlled.
MeshCAM is also available at checkout as an option, and it is an incredible piece of software for people without an engineering background. Check out their site here for more information - http://www.grzsoftware.com/
