    Nice build! You'd probably make a few people happy if you shared your mount designs on Thingiverse.

    Nice build Aaron. I was wondering if you could share info on the spindle that you purchased and how it is working for you. Again great job.

    Thanks Roger. I didn't really have a strategy when I purchased the spindle. I just followed the advice of some CNCers from another forum and went looking for spindles on eBay. I just looked for a vendor that was close and could ship quickly, someone who had a high rating and a spindle with specs that sounded about right. The vendor I purchased from had sold hundreds of this spindle. Although the spindle is made in China, I purchased from a vendor close to my house. My only complaint was that the controller I received was slightly different than the one pictured in the eBay listing. The eBay listed controller clearly has a separate hookup for TTL OR speed control by potentiometer (choose one or the other). The controller I received only had one connection so initially I was a bit confused how to use TTL to control spindle speed via G-code.

    I paid $77 for the spindle, including shipping. The vendor I purchased from is here: CNC 400W Brushed Spindle Motor 4pcs Set Tool Kit 12000RPM Mount NEW GENERATION | eBay

    The spindle works great. Very strong and extremely quiet compared to a DeWalt router. I really like being able to control speed via G-Code. My cheap desktop CNC can only move at 300mm/m at it's fastest speed so it's crucial that I can slow down the spindle when cutting ABS or other soft plastics, otherwise the plastics just melt on the bit.

    I've been using bCNC running on my Raspberry Pi to run the machine but I also plan to use the OpenBuilds software. I just really like using the Raspberry Pi since I can easily remote desktop to it from my PC at my desk instead of having a dedicated PC at the CNC machine. I also love running the bCNC pendant in a web browser on my iPad for controlling the CNC. I mostly use SolidWorks to create models, both 2D and 3D. I usually use CamBam for generating my G-code since it runs on Windows and Linux.

    First cut today on the LEAD CNC machine. I swapped out my controller and purchased a Black Box from OpenBuilds and now I can say I've done my first cut. Well technically, this is the second cut on the new machine. The first cut was a vertical and horizontal line in the spoilerboard at 0,0. This is my DJ logo engraved in brushed silver/black ABS on the back of my laptop with carpet tape.

    You are the man. Great first project. Thanks for the info. I think I need to get one of those spindle things.
