    If using a milling or laser machine, I would just fire up grbl on an Arduino for controlling, can't beat the price on that. One needs a computer anyway to do CAD/CAM and there is lots of software for sending files and controlling grbl through the computer. If not needing a CAD/CAM, then I would pair up Raspberry Pi and a grbl controller for a cheap, fast, small and easy to use package. But the requirements of different people dictate different means, for example the grbl can't do lathe at the moment.

    Why can't grbl work on lathe? It's just a 3 axis g-code controller. Up to you what the axis do. If you are taking threading, then yes, someone needs to write a module to sync feed/spindle. I'm surprised it hasn't happen yet but believe it's mainly because most user have mills or similar. GRBL is some on the tightest code I've seen; beautiful work that will go far.

    What intrigues me about the Centroid controller is that software has conversational mode. I use Conversational Mode daily (Acu-rite 3 axis Millpwer on a BP, but conversational on my model is limited to 2.5 axis) and don't have to resort to G-code or even cad. I typically make 1 through 2-3 parts... most are done before I could have done the cad/G-code cycle. I can punch in a complex part, watch tool simulations and solve geometry (like intersection of arcs, splines etc) on screen. I never have to worry about tool widths, offsets etc.. if I want to change from say a 3/8 to 1/2 inch end mill in the middle of a job, I just change the tool type in a second. Same with tool center, left/right - I just tap the soft-key to change that. Expert g-coders aside, Conversational modes will open up the market to us lessor beings quickly.

    You are right, it could be used on a lathe by changing the code just a little for the X axis, but the main issue is like you described, no spindle/feed synch and no X-axis tied spindle speed output. I know it is in the works, but might be a long time since "everyone" has a 3-axis 'mill' (routers, printers, lasers etc). The code is truly remarkable, it really makes use of every known trick on an Arduino to get everything working fast.

    And what you said about the conversational part, I'm so used to it on a Heidenhain that I couldn't live without it. Makes it really fast and simple to start carving some (simple) parts that you only have as a draft on paper. Plus the code is easy to read english (localizations aside), unlike G code.

    Anyone have opinions on the Siemens 808d? Quality, customer support, user friendly?
    I'm wondering if it's a good alternative to Mach3, Masso, or the generic Chinese controllers?

    It is a good proven controller but a bit aged now.
    It's biggest limitation is the basic controller is just that - basic.
    Any improvements or extras are paid add ones.
    The closest unit you have mentioned is the stand alone Chinese one which comes fully featured for the model you buy.

    By that I meant if you buy a 3 axis controller it does everything on 3 axis. If you want 4 axis then you have to buy the 4 axis model.
