I was running two printers, and had several remote windows open watching the progress.
Console was a bit slow, and I was noticing that it was getting "stuck" occasionally...
Opened up Task Manager and was surprised to see CPU utilization sitting at 96%, and it stayed there...
Had lot of memory available, but no cycles. Disk and Network were also fine.
I guess it's time to retire my ancient i3-Dell tower.
(No wonder the rendering took so long)
Now I have to remember everything needed to Run Repetier...
Repetier-server
YawCam x2
MMP3 conversion thing...
Anything else??
