CNC Routering and Machining as a Maker or DIYer is an onerous proposition. This is not because of the machines themselves but because of the software. Of course there are extremely capable and functional programs from the professional world, but as a home gamer who doesn't want to spend money, how can we make sense of this convoluted environment and navigate to a functional workflow that allows us to cut the things we want on our CNC machines?

This is Part 2 of the series where we upgrade an Ender 3 to be competitive with the Prusa I3 Mk.3 for less money than you would spend on a Mk.3. This video is all about the wiring - where to connect things and how to do it.

Even in these times of great success for Tesla, there are people who want to hate on Elon. He is human, and he makes mistakes, but he is a gift to the modern world. We are lucky to have him.

My wife asked me to make her a pinwheel for Valentines Day. I obliged and ended up with the most spectacular and compelling 3D printed object which I have ever made.
Apparently, the company no longer sells the Rainbow filament, but it's high quality PETG that they make, so here is the listing to their other products: https://www.amazon.com/Filament-Degradable-Dissolves-Printing-Dimensional/dp/B088FTS5HF/ref=sr_1_23?dchild=1&keywords=PVA%2BPrinter%2BFilament&qid=1604281287&sr=8-23&th=1

Just a little feel good video about improving the neighborhood with 3D printing by making a fix to a playpark feature. Shout out to "99 Percent Invisible" who taught me the terminology in their episode on the subject.

A review of the Creality Ender 3 3D printer from frame assembly to the test prints, and all the little details. This thing performs extremely well. NOTE: The filament spool holder issue has been remedied. Please see the pinned comment by Philafxs. Also, for those who are curious about the cork, it is a cork wall tile from my local hardware store. It is held in place by the springs under the bed. No adhesive necessary. Finally, I spoke incorrectly, the power supply is special because it is 24v vs the 12v we typically see.
The printer is $209 at Gearbest: https://goo.gl/ZFRccD
There is an upgraded version called the Ender 3 Pro with a magnetic flexible bed. You can get that at Gearbest for $259 with Coupon:GBEnder3pro: https://bit.ly/2O3m2Tq

Consumer level filament drying solutions are all just glorified food dehydrators, and they cost way too much. I got a $30 food dehydrator and modified it into a Filament Dryer for about $60 in materials. Unfortunately, the original heater doesn't get any hotter than about 150 degrees F (68 degrees C), and that's not hot enough to get your filament dry.

Mechanism Monday #2 - More 3D printed gears! Building upon last week's device, we continue playing with the double rack and pinion gearing to get some interesting motion.

In part 1 we built the router and did a test engraving of a piece of wood. In this video we will do a real project and make a metal engraved name plate using a new free/open-source software program. The whole process is shown in detail from drawing the artwork to generating and modifying the Machine's operating code (gcode). If you were ever curious about CNC machining, this is a great place to start.
To get a copy of the updated firmware, please donate $1 to my Patreon and then send me a message over there asking for the "T8 GRBL 1.1 hex file" : https://www.patreon.com/designprototypetest
