After tinkering with making a 3D stamp yesterday, I thought that maybe I would tinker together a stamp for the QR code that would send you to my resume-ish site mvandewettering.com. I had used the qrcode library in python to generate them before, but it wasn’t clear to me how to use that to generate […]

Apologies to Hermes Conrad. Further apologies to those who won’t get this Futurama quote. During COVID, I spent some time in my shop doing more woodworking. At the time I was trying to figure out how I could sign the work that I did, mostly for fun rather than ego (my woodworking skills remain modest […]

I’ve been an on-and-off enthusiast for 3D printing for quite some time, but in the early days, it wasn’t what I would call “practical”. They used to be fairly unreliable. In particular, my aging Creality CR-10 had difficulties with bed leveling, and while I kept modifying it to add sensors like the BL-Touch to automate […]

I’ve had my Creality CR-10 for quite some time, and fairly early on I decided that I needed a bed leveling sensor. It wasn’t just because it was difficult to level the bed. The bed itself isn’t anywhere close to flat. Since the printer doesn’t know that, you have all sorts of problems with adhesion. To be honest, I’m […]

Over the last couple days, I’ve been pondering my journey through 3D printing. After having taken a three month break from it (more on that below) I’ve managed to get my Creality CR-10 back up and running in a reasonable way, and have donated my Anet A8 (my gateway drug to the world of 3D […]

I’ve been wanting to make a computer-controlled mechanical gadget for quite some time. When I finally got a 3D printer a little more than a year ago, I began to think of how I might make a device that could direct a pen under computer control. I even took the time to order a CNC […]
