« Part 3: Part 3: Updates and Need Ideas Part 4 of Making a CNC Router series no next part

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

I purchased all the electronics from:
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:

Thanks for Looking! Comments and questions are welcome!
