Man Down!
One of the Vorons is down! My guess is a faulty stepper motor driver. The extruder makes buzzing sounds and the motor goes back and forth for some reason when loading filament. Seems like the motor and gear train are fine, they rotate manually without making sounds. If it’s not the drivers, it could be the stepper motor itself. Since drivers are easier to swap, I have some on the way from Amazon. At least I can still print with the second Voron. Not bad for 1,500+ hours to have a first serious problem.

Not too long to go before the next plate…

Printing, and more printing!
I decided to break out a project I started a while ago (a common refrain) and finish re-printing some parts of this 3D Sets model:
All of the body pieces are printed, but the filament I chose for the mechanical parts (gearbox, suspension, etc) was a little too rough and not really printed very accurate, so I’m re-printing those parts with Polymaker PLA which I’ve had way more success with.
This printer has almost 1,500 hours on it and still going strong.

More Printing
This is the latest sign, another NYC logo.
This one was a bit over-extruded because of some first-layer issues I was having, should not have bumped up the extrusion rate that much to compensate for the nozzle being a bit high for some reason. That reason being probably some dried up plastic stuck on the nozzle. The Voron Tap is great otherwise. This machine used to be a nightmare to QGL and mesh, but since I upgraded to Tap it levels quickly every time, and breezes through a mesh. I’m eagerly awaiting a chance to install it on my second printer.

Battery Bank Prototype 2
The latest version with integrated boost converter for charging. After completing and testing the Battery Bank Prototype 1, I was ready to move onto some of the next features I wanted to add. For the second prototype I focused on the switching boost converter charge circuit. I’ll briefly go over the design of that and how it relates to charging the battery pack.

T-962A Reflow Oven
I was recently asked about how I go about reflow soldering, so I decided to do a quick write-up on my oven and process. I bought this oven several years ago on eBay, and you can still find them today. While I did consider the modified toaster oven route, in the end I decided that a box that was purpose-built for reflow was a better choice in the long run.

Battery Bank Prototype 1
Motivation
I got interested in the idea a few times over the last few years, but after seeing some cool power bank projects and tearing apart a few e-bike battery packs, I decided it was time to design my own battery bank. As I knew little about batteries before starting the project, I decided to start simple, and for the first prototype I created a simple 6-cell Lithium-Ion battery pack.
