Multi-use CNC machine framework capable of 3D Printing, milling, and cutting.
The LETU-Maker is engineered to be a modular CNC framework that can preform a wide variety of tasks. Going beyond a simple 3D printer, LETU-Maker is designed to be robust while remaining cheap and easy to make.
The design makes use of a modules attached to the x-carriage which share a common mounting style and connector pinout making changes quick and easy. Current modules include
- 3D Printer Extruder
- Hot Knife Blade
- Driven-Blade Plotter
- Rotary Tool Mount
Several other modules are being developed such a laser cutter. In the figure below, the base can be seen with the 3D Printer Module fitted.
The design is derived from the LETUs-RAP which was developed at Letourneau University during the Fall of 2014 for a freshman engineering lab. The original design was exclusivly a 3D printer and suffered from several drawbacks such as a lack of rigidity and frequent extruder failure. This new design solves these problems and others while expanding its capabilities to several other common Maker activities.
