Filament Health Monitor (Part 1 – Introduction)

Introduction / Summary The Filament Health Monitor is a Web Enabled 3D printer Filament Monitor System and spool holder. This setup will monitor and report the following to a custom web view/api: Weight of filament left (upto 5kg) Humidity Temperature Color of material loaded It also includes a small LCD screen which reports the weight, humidity and the current IP […]

Rediscovering Wire Wrapping

Background Think of wire wrapping as a permanent (Although revisable) form of bread boarding.  It is a technique for producing highly reliabe low cost / low run count electronic assemblies.  In fact, it was so much so that it is the technique used for the Apollo guidance computer used to go to the moon and that survived a rocket launch.  […]

Arduino Development In Visual Studio Code

Arduino and its associated IDE (Integrated Development Environment) have been a stable of many of my projects. Even with its utility, it lacks many of the features I have grown accustom to in my other development endeavors. I usually work in Visual Studio Code (VSCode) and got to thinking, “Why can’t I us it to edit my Arduino Sketches.” Well, […]

GRBL Custom RPM To PWM Mapping (Custom CNC Part 5)

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 […]

Working with GRBL (Custom CNC Part 4)

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 […]

CNC Electronics (Custom CNC Part 3)

If you are just joining us, take a look at part 1 and 2 at: Custom Built CNC, an Introduction Building the Structure, Folding CNC 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. […]

Folding CNC (Custom Build CNC – Part 2)

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 […]

Custom Built CNC – Part 1

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 […]
