CNC Electronics : Arduino Uno + GRBL

After some considerable delay since I first started with the idea of building myself a cnc router, I am now working on the electronics in earnest.

Having decided to get an arduino to make my electronics easier, I then found out how much easier when I discovered Grbl, a gcode interpreter written for the atmega chip that is, among other things, used as the heart of an arduino.

You can see it in the video above, at the moment it is not gripping the stepper shaft, for that I require some m3 bolts/machine screws to tighten up the coupling.

This are starting to look pretty real now, I have a few adjustments to make to my physical rig, and I’m still a little concerned about the sloppiness in the x-axis, I need to make sure I eliminate the side to side without making the friction bad. I have a few ideas about how to achieve that, we shall see how it goes. its quite exciting to finally be coming towards the stage of actually connecting motors and trying it all out for the first time.
I’m anticipating a considerable amount of fettling, and part of me suspects i may need to build a whole new rig with better materials, but I’m going to give it a damn good try.
