How-To: Build your own CNC machine (Part 3) Back in Part 1, we introduced the basics and started building the electronics.
In Part 2, we finished up the controller and started building our machine. Today we complete our unholy marriage of cutting boards and dot matrix printers in Part 3 of How-To: Build your own CNC machine. Good luck. Last time we showed you the completed base, with the first axis. The screw drive turns easily and there's very little play in the motion of the table. The design of the upper axis is simple, but is the most difficult to execute. A simple tower constructed of three pieces forms the basis for the rest of the machine. The center slider is the most complex to build. To effectively deal with the minimum space, we had to get tricky. This slide and carrier were salvaged from an old Okidata printer. We whipped out the drum sander attachment on our dremel tool and contoured the plastic on the bottom so we could mount the printer slide without compromising the integrity of the cast metal.

Here are a few of our design goals: Modular Design – We wanted to do more than just keep cost down. We wanted things to be reusable and up-gradable. (Arduino , Individual Stepper Motor Drivers and more…)Compact Design – Squeezing a 4 axis design into a board the same size and Arduino Uno.Opensource Software – 100% GRBL compatible (G-Code Interpreter)Evolving Development – We are keen to improve on the design and welcome all feedback.

DRV8825 Stepper Motor Driver Carrier, High Current. The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 microstepping bipolar stepper motor driver.
The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications. The DRV8825 features adjustable current limiting, overcurrent and overtemperature protection, and six microstep resolutions (down to 1/32-step).
It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling). Overview This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet (1MB pdf) before using this product. This product ships with all surface-mount components—including the DRV8825 driver IC—installed as shown in the product picture. DRV8825 Stepper Motor Driver Carrier, High Current.
