I went out to start up the mill today, and found that the PP control won't move the axes. Once the mill and PP are started, I can start the spindle, and jogging commands do cause the DROs to advance. I can manually turn the X-axis ball screw. No error messages. I checked all the cable and connections and all are secure. Mill was running fine before last shutdown.

I thought I'd post here in case there was something obvious to check before I tear covers off the computers.

If I disconnect the PP computer from the Novakon box and restore the loopback cable, I should be able to still run Mach3 on the CD100. I didn't feel up to that today.
