This means you can buy the machine that meets your exact needs with the size system that will fit perfectly in your work shop. You have big ideas and we have a big CNC to match. The D.840 is our largest D-Series with plenty of room for your hobby or small business to grow.
A PRECISE DESKTOP CNC SYSTEM
Our goal with the D-Series line of CNC systems is for anyone to be able to assemble their machine and have it be perfectly aligned to a high level of precision right out of the box with no special tools. We have exceeded this goal with the D-Series machines. Each machine is self aligning to the correct tension eliminating the time-consuming process of final machine alignment. This means you can concentrate on assembling the machine knowing it will be ready to start milling as soon as you are done. This considerably simplifies the assembly, as compared to our previous versions.
Our adjustable lead screw nuts are now a standard part of every D-Series machine. They allow you to be able to fine tune linear accuracy over time to achieve highly accurate repeatability numbers not commonly seen in desktop CNC systems - outperforming all CNC machines in its class.
The D-Series machines now feature an All Steel Motion System modeled after our proven industrial design of the Q-Series systems. This motion system has been engineered to fit perfectly as soon as the machine is assembled. There is no longer a need for any adjustments as the steel shafts run absolutely parallel with the correct amount of preload right out of the box. This ensures an ultra-smooth running gantry system that is rigid, precise and can withstand thousands of hours of use holding the same tolerances as the day is was new.
NEAT AND PROTECTED
The igus® cable chains protect and guide the cables through the machine. This increases the service life of the cables and protects them from outside obstructions or damage. CNC Accessories can be attached to the two T-slots on the Z-axis. The cables can be routed cleanly and conveniently using the Flexi Guides™ on the X-axis.

MULTIFUNCTION SYSTEM WITH CNC ACCESSORIES
At STEPCRAFT we have always been know for our vast line of CNC accessories and attachments which provide true multifunction capability for each of our CNC systems. Because of this, our base CNC machine can be used for precise milling of many different materials or it can quickly be converted to a CNC laser, 3D printer, Plotting, Cutting or Engraving machine. Unlike many other "multifunction" machines on the market, STEPCRAFT machines truly perform as well as a dedicated system designed for that accessories purpose. You get the same rigidity, performance and accuracy whether you are milling aluminum or laser engraving wood. This means you can outfit your shop with many solutions all within the same footprint and you can quickly switch back and forth between attachments in a matter of minutes. The application potential for the STEPCRAFT D-Series is virtually limitless.
You can process a wide variety of materials to create a limitless number of projects on your D-Series CNC system using our MM-1000 DI Milling Spindle. The MM-1000 DI is a digitally controlled 1000 watt spindle that will effortlessly mill through hardwoods, plastics and non-ferrous metals. The spindle will turn on and off with the software and the RPM is controlled by your settings in your CAM program. The best part of the MM-1000 DI spindle is that you can add an optional Automatic Tool Changer to fully automate your D-Series CNC. You simply choose the tool number in your CAM program and the CNC will do the rest. This allows you to operate your D-Series CNC in an unattended manner while you can use your time wisely for other tasks.
You can add a 3D print head to your D-Series CNC system and transform your milling machine into a full-function 3D printer for your home or business. Incorporating additive manufacturing capability to your CNC means you can now produce some very complex projects that would be too complicated for a 3-axis CNC milling machine. You can add the optional component fan to the laser to print sharp surfaces easily.
The STEPCRAFT DL445 laser attachment can be added to your D-Series machine and give you the ability to laser engrave into a wide variety of materials such as woods, plastics and even some metals. The powerful 3W laser can even cut thinner materials into intricate shapes. Since the laser and milling spindle use the same tool holder with the same XY zero, you can quickly interchange both tools to mill and then laser engrave in the same project.
The OTK-3 Oscillating Tangential Knife is used for making very precise cuts in a wide variety of materials such as cork, rubber, foam, cardboard and more. The knife blade oscillates up and down allowing you to cut rapidly and the blade is also steered by a stepper motor so it is always facing the direction of the cut. This allows for much more precise cutting than a traditional drag knife cutter.
SELF ASSEMBLED MACHINE VS. FULLY ASSEMBLED
The STEPCRAFT D-Series CNC systems are available as a CNC kit or as a fully assembled solution.
