The 3018 Pro CNC Router

I recently borrowed a SainSmart Genmitsu 3018-Pro CNC Router from a friend (checkout his site and YouTube channel!) to play around. After trying some general CNC, I wanted to try out using it as a 2D drawing bot. Yes, you can use a regular printer to print, but where is the fun in that?!

I was pleasantly surprised to see that someone already tried doing this and was nice enough to share their work. Here is what I had to do.

  1. Disconnect the default spindle so I don’t accidentally move it while experimenting.
  2. 3D print this Sharpie holder and install it instead of the default spindle.
  3. Followed this tutorial to create the gcode with Carbide Create.
  4. Connected the CNC to the computer using USB connection.
  5. Used SainSmart’s GRBLControl/Candle to send the gcode to the CNC.

The result? Let’s see!

Yes, it’s a bit slow and can be sped up quite a bit, but I didn’t bother doing that. This was a good weekend project and I enjoyed learning about Carbide Create, Candle and the CNC in general.
