Ok, new information. It seems spindle operation is being disabled due to complaints about "unexpected real time delay", without any visible notation in LinuxCNC that anything has been disabled due to an error (poor form).
To summarize the setup: The PC is one I built a year and a half ago, though I put in a new SSD dirve for this retasking of the PC. The PC is 100% dedicated to the lathe. It's based on an ASUS F1A55-M LX Plus R2 motherboard, with an AMD A8-3850 CPU (4 core, 2.9 GHz) and 4GB of ram. I put a basic cheap video card in it since I'd read that the onboard graphics were often a problem, but this "unexpected realtime delay" seems to exist with either graphics adapter. The install was from a USB thumb drive with the latest hybrid ISO image, installing LinuxCNC 2.6.3 with all it's defaults. I didn't have the PC on the 'net when I did the install as I had to make a long cable to connect it, but I did do the available updates and upgrades later and they had no effect on this issue.
