STEPCRAFT 420 - Desktop 3D-System

The universal desktop CNC-/3D-System to live your ideas

Become an expert

Become an expert and customize computer based workpieces to real models. With a suitable drawing program, such as CorelDRAW ® or the open source software Inkscape, you can create a work file with which you then control the desktop CNC-/3D-System: Accurate, efficient and reproduced as often as you want. The workpiece materials are virtually unlimited: Using the STEPCRAFT 420 and optional accessorie-tools, materials like wood, thermoplastics (PS (polystyrene, such as Styrofoam ®, EPS, Depron ®, Selitron ®), ABS, PE (polyethylene), PP (polypropylene eg EPP) Weich-/Hart- PVC, Lexan ®, polyamide, Plexiglas ®), some elastomers / thermosets, mixed materials, such as DIBOND ® or electronic boards, to Carbon / Carbon and non-ferrous metals (aluminum, brass or copper) can be processed

Excellent quality at a fair price

To ensure sufficient accuracy and stability of the machine, the STEPCRAFT aluminum profile series has been developed. It consists of two different linear track profiles and the cover profile. All other connecting elements consist of aluminum or stainless steel and together with the profiled structure they ensure the required rigidity. The stepper motors from Nanotec® have been carefully selected and specifically adapted to exactly fit the machine. The electronics have been specially designed to match the characteristics of the motors so that sufficient power for a reliable operation of the 3D system is ensured.

DIY-Kit or ready built machine

The machine is available as a DIY-kit or as a directly operational system. If you opt for the kit, you save money. The construction of the machine is designed so that you can simply build up the machine within a few hours without any special tools. Only screw together - done! The EasyBuild installation instruction needs (almost) no text. The step-by-step instructions are based on chronologically numbered instruction steps with graphic images of all intermediate steps. The last section always shows the finished assembly so that you can easily check your own result.

Complete Equipment

The machine, whether as a DIY-kit or ready built machine, is supplied with all necessary components for operation: All necessary mechanical and electronic components, such as Power supply, connecting cable are included. Not included are the system-based tools.

Innovative System

The STEPCRAFT 3D system includes many practical innovations that improve or simplify the work with the system: Stable STEPCRAFT profile system, Integrated workpiece clamping system, easy adjustable clearance of the linear guides, seals for protection against dirt, integrated / modular control electronics.

Compatibility

Due to the 43mm collar a wide range of tools can be used. With optional adapters, you can also use Proxxon or Dremel tools as drilling-/milling spindles directly. Other drilling-/milling spindles up to a power limit of 500 watts can also be used. Other system-guided tools, such as a drag knife, engraving needle or hot cutting system can be used optionally.
With the parallel interface of the STEPCRAFT 3D system many CNC-software, such as EMC2, Mach 3, and more can be used.
