If you are just joining us, Part 1: Custom Built CNC, an Introduction Part 2: Building the Structure, Folding CNC Part 3: CNC Electronics Part 4: Working with GRBL The Problem: My router has two different attachments, a wood router and a laser burner. They both need to be controlled using the same Mega and I want different RPM input […]
If you are just joining us, Part 1: Custom Built CNC, an Introduction Part 2: Building the Structure, Folding CNC Part 3: CNC Electronics Introduction Grbl is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling. This version of Grbl runs on an Arduino Mega2560 only. The controller is written in highly optimized C utilizing […]
If you are just joining us, take a look at part 1 and 2 at: Custom Built CNC, an Introduction https://replicantfx.com/cncpart1/ Building the Structure, Folding CNC https://replicantfx.com/cncpart2/ Version 1 (G251 + parallel breakout board) It took me a long time in life to realize I should do it right the first time, but lets not be too tough on me. […]
Finally I have gotten to talking about version 3 of the CNC router. (Want to see where I started: Part 1)I learned my lessons, pulled on my big person pants and finally did it right. Doing it right started with getting the base table right. For years I had been designing bases out of wood because welding and working with […]
Welcome everyone. To cover my past and current Computer Numeric Control (CNC) build will take a few posts. I will be breaking up the documentation and discussion into sizeable chunks. I will introduce the first few builds but avoid the deep details. The final build will be full of details as it is built using all of my lessons learned […]
Intro If you are reading this post, you most likely already know about the cheap 40 Watt CO2 Lasers available from China which are commonly referred to as K40s. There are several sub variants of the K40 but generally they are in a white and blue or red steel case and have a cutting area of 12 x 8 in […]
I usually don’t include bolts and nuts in my CAD assemblies, but this was mostly do to not having CAD files for these things readily available. I decided to fix that and create nut and bolt sets: Metric Button Head: https://www.thingiverse.com/thing:3402872 Metric Socket Head: https://www.thingiverse.com/thing:3402887 Metric Nuts: https://www.thingiverse.com/thing:3402714 Each set contains *.STL, *.F3D and *.STP files and have been optimized for […]

I love RIDGID’s Oscillating Edge/Belt Sander. Overall, it is a wonderful addition to my shop and has served me diligently since 2012. It sits on a mobile flip top cart that is shared by my plainer. Now, it is a beautifully useful tool, but the nut on the top of the spindle, the star shaped one that holds the […]
