Most of them can stream gcode to the controller over usb serial, and many also have the option to I notice the Smoothieboard uses the same user interface software as the ATMega-based 3D pritner controllers. Is there any such host software which would be effective for serious machining (say, with a Sherline lathe or mill)? All examples I've seen of using this stuff for CNC machines involve Dremel tools bolted to 3D printer frames. Could any of this software handle things like changing tools, or using a probe and toolsetter? CrazyLittle posted:There's always the smoothstepper, which has its own usb or ethernet interface. The problem there is that you need the Mach3 CNC software to use it, which doesn't always do that great with newer versions of Windows. I've used it (the USB one, I have no idea if the ethernet version offers any real-world improvement) on a Windows 7 netbook, and every "new updates available" notice from Windows triggered the emergency stop.

I was looking at one of those cheap Chinese things that consist of a box of parts which can be assembled into a bunch of different tools (such as a lathe, mill, and sander): http://www.hobbyking.com/hobbyking/store/__87843__Big_Power_Mini_Metal_8_In_1_Kit_HK_US_Plug_US_Warehouse_.html I've wondered if it would be at all possible to convert something like that for CNC without interfering with its ability to be reconfigured.

Karia posted:Haas machines are all closed-loop via encoders and servo based. I can't think of a single professional level (anybody better than Tormach) cnc manufacturer that uses steppers. They're smaller, better accuracy with the encoders, better torque/power curves, and much, much faster. Cost and tuning are really the downsides, but the performance improvement outweighs it. There's also these controllers, which take step/direction inputs like a common stepper controller and drive a common DC motor with an encoder: http://www.cadcamcadcam.com/servo.aspx http://www.geckodrive.com/geckodrive-brush-dc-drives.html Some of the Mesa controllers can also directly connect to DM motors and encoders. I haven't used any of those personally, but it should be possible to combine one with a cordless drill motor and an encoder and get some level of closed-loop control for a fraction of the price of most servomotors.
