Revision as of 23:47, 20 April 2016

I've been wanting to build a CNC machine for a while, but have gotten distracted by various other things. I finally did a minimal amount of research and bought some stepper motors and a controller. I honestly jumped into this pretty quick, though, and didn't spend a lot of time researching what I was buying. I'll update this as I learn more about what I bought and, if necessary, what I should have bought instead.

Controller

I started with this controller:

It's about $39 and includes:

  • 1 x 1.4 RAMPS Arduino Shield
  • 1x MEGA 2560 R3 16mhz Clone
  • 4x A4988 Stepper Driver rated at 1A and cooling with up to 2A, Note: this board now comes with heat sinks.
  • 1x 12864 LCD Screen with board with SD card interface

I guess it was a mistake, but they actually sent me 5 drivers. I won't have extruders, so apparently I only need 3, but I guess I'll have a couple extra in case I burn one up.

Motors
