Alright, to re-visit this sticktion theory. It's cold again in east PA tonight.. the oil thickening makes sense. Tonight I got home, I powered up all the equipment. I have a small ceramic heater out there... I turned it on for about 15 minutes. Wiped the machine, oiled it.. moved the tables about a little, strapped on the stock and ran a new code I generated tonight.
The Y stalled 500 lines in. I flipped the stock, zero'd, restarted.
The Y stalled a few hundred lines in again.
That time the stock was barely cut so I just restarted it.
Y stalled 1000 lines or so in.

WTF?
I thought maybe it was this new code.. I loaded last nights code and it seemed to work. Weird. Okay, I got a new piece of stock. Loaded the new program again and ran it. I just checked and its running fine.
Could it be that the machines ways and motors just have to come up to temperature? Should I run some ghost code just to get it all warmed up before starting any cuts?
What do you think?
