My Homemade CNC Router Table (part 6)

 

< Go back to Part 5 of How I am Building My DIY CNC Router

homemade cnc router tableI seem to only get any building done on Sunday nights lately.  Have a day job puts a real damper on my Making aspirations, but I try really hard to get something done each week.

This past Sunday, I added the z-axis to my diy CNC router project.  It certainly has that homemade quality to it.

I added smaller drawer slides to the vertical framing of what will be the holding plate for the router (or plasma cutter) that will eventually be fitted to the CNC.

If there is a lot of backlash and stickiness to the slides, it may severely affect the cuts and ability for the stepper motors to move things effectively.

I’ve added a couple videos to my youtube channel.

Here are the two newest videos I’ve added to the channel.  You’ll see how sticky the slides are–especially for the z-axis–I think some of the wood may have warped a little.  I didn’t necessarily adhere to strict precision guidelines in its installation.  In fact, I stuck to my philosophy that “eyeballing” everything is pretty accurate, within feet.

  1. Been enjoying watching this project take shape. Have you done anything new on it?

  2. I’m planning on getting the threaded rods placed in the coming week–and trying to test the nema 17 stepper motors with my arduino uno and the new easy drivers that arrived via Hong Kong express.

  3. Thanks for sharing the instructions for building a CNC. I will be working on putting together in a couple months.

    • I’d recommend making your rails either out of drawer slides, or UHMW and pipes. Good luck! It’s all about the learning experience–and you will learn a lot!
