Making a CNC Router Part 4: Electronics

Posted on May 10, 2011 at 4:28 PM

 

After a few months of saving money, I finally got all the electronics for my CNC!


I purchased all the electronics from: http://buildyourcnc.com/electronicscombo.aspx

which include:

(3) 425 oz-in stepping motors

(3) Drivers (3.0Amp 24-40 Volts, 1-1/64 microstepping)

(1) 36v 8.8a Power Supply

(1) Breakout board

Then I built a box out of poplar and Plexiglas to house all the electronics:









Then I tried out the monitor shelf that I came up with in the last blog and I got a new monitor and the shelf was way too small:



I also got a new computer and needed somewhere to mount it:


So, I came up with this 2.0 version of my monitor shelf (bigger and better):



I also added a few switches to control the CNC:


The “Router and Shop Vac” switch controls this outlet that I wired up and plugged in the router and shop vac:


Then I got an E-Stop and limit switches from CNC4PC: (I still need to wire them up)



Here is a video of me wiring the electronics:

Nice overview of your project. I purchased the plans also and am now gathering materials to build a similiar unit. What plug-in did you use to convert the Sketch up drawing to the Mach 3 g-code? Nice work with the Sketchup. I have found a couple of variations of this plan on the 3-d Warehouse.

Thanks Greg,
I have two plugins that I use, one is a DXF or STL file exporter and the other plugin is Phlatboyz.

I built the book CNC as well. How long did it take you to complete? Took me a while to get it all together, but it is/was mostly a weekend and free time project. I need to build myself a table for it and I like your table design do you have any dimensions or "plans?" Thanks!

ollenberger,
It also took me about a weekend to make. If you would like, I could send you the Google Sketchup file of my stand plans.
Thanks,
Kyle
