New Life for old 3D Printers

I’ve used and abused my first 3D printer for about 2 years. It had print quality problems and my recourse was to buy a new cool delta printer. But is there any way I can refresh that 3D printer I just about gave up on? I decided that an updated firmware may be something I […]

Octoprint and Reverse Proxies

I have two active 3D printers, each hooked up to their own Raspberry Pi 3 running Octoprint. I like to manage them from my iPhone when I’m about. I don’t want to expose my IoT devices to the Internet without some precautions. Here’s how my Internet connected house is setup. The diagram was created and […]

3D Printing the WordPress logo in two colors

My 3D printer only supports having one filament loaded at a time and that generally means the objects I print is one color. I wanted the WordPress logo (naturally) and two colors would be cool. I can print pieces in different plastics and assemble them but sometimes you want one piece. Good news! My printer’s […]
