It's nearly inevitable when any suitably complicated project drags on, or even goes on hiatus. Eventually you're going to start daydreaming new ideas and features for the build. The Doozer was no exception to this. The trick is to try to make sure that the feature creep is actually a reasonable addition that can be missed out if need be, due to budget or skill constraints.

The Doozer CNC Gantry is a custom built CNC tool platform, essentially a computer controlled robot that can use a variety of attached tools following computer instructions. Most commonly envisioned for use with an attached WEN 2347 Variable Speed Rotary Tool, to act as a 'desktop' scale CNC milling machine; the Doozer CNC has been designed with modular expandability in mind, allowing it to utilize a variety of cutting, marking, and other tools to create a work platform that can perform a fair number of computer controlled tasks.

I utilized the Harbor Freight compound mitre saw, with the installed wood-cutting blade, and experienced no issues with cutting through the aluminum extrusion. The only issues I encountered were due to missing clamps.
I attempted to assemble a few pieces utilizing the brackets I already had. The 3D printed PLA brackets worked like a charm, but the lasercut acrylic brackets shattered under the mechanical stress created by the V-slots in the aluminum extrusion.
A full 8 hours later, I had a mostly assembled Y-Axis (the left one). In the process of assembling it, I discovered that my design for the "T-Nut" holder brackets needed reworking. After a bit of redesign work later that evening, the files were sent off to Ben for printing. Within a couple of days, the new parts were dropped off.
While the amount of assembly work that lays ahead of me can be quite daunting, I can say that I'm excitedly looking forward to the next time I'm able to head down to the shop to work on this project!
In the meantime I've begun collecting video tutorials on the electronics portion of the project. While I'm not 'there' yet, I know it's looming on the horizon.
