    Nice list you have going here Chris!

    I’m like a walking advertisement for buildlog.net right now, but I’m really <u>really</u> digging their 4 axis open source CNC controller (here: http://www.buildlog.net/blog/2011/08/open-source-4-axis-stepper-driver/)

    It uses the pololu drivers (2A max per motor), has active cooling (fan), and works really well with EMC2. When I’m not using one of the grbl boards (grblShield, stright grbl with breadboard, stepper shield, etc) I’m using this controller and so far it’s been flawless.

    I’ve used a lot of different boards over the last 6 years (xylotex, hobbycnc, and a some Chinese knockoffs from ebay, among others) and the one thing I really like about designing around the pololu drivers is that they’re cheap ($12) and replaceable. So if you blow up an axis, just pop the driver out of the board, and replace it with another. Most of the other designs would require you to replace the whole board.

    A second “cool” point about the buildlog.net controller goes to the idea that you can control a relay, which in turn could control the spindle, through the 4th axis! You can read more about that in this blog post: http://www.buildlog.net/blog/2011/10/pololu-compatible-relay-driver/

    Just so there’s no confusion. I do not *recommend* the cnconabudget.com 3 speed spindle. Yes, I own one, and yes I occasionally cut with it, but it’s nothing more than a glorified Dremel. There is noticeable runout on mine and I don’t think it justifies the price tag over a regular $40 dremel.

    With that being said, it looks nice, is a little quieter than a dremel 300, and is straight forward enough to work in most situations. But again, it’s not any better than a regular dremel.
