Standard AVID CNC with their electronic package. Very new HP Pavilion laptop - W10 upgraded regularly. Nothing exotic or exciting or unusual in other words.

Used the machine a day or two ago. Worked perfectly, as usual. Fired it up today and all the sudden, the motion will run along as expected, nice and smooth, than all the sudden it gets jerky, I noticed it on all 3 axis. I ran a program just to flatten a piece and it was obvious something was amiss. The surface has a couple of sections where the machining is pretty rough.

Any ideas? I think there was an Intel update recently that said something about Serial control or something like that. I ran the Warp 9 installer and everything looked fine there. This seems to be intermittent.

I just shut everything down and took a break. I'll keep working on it until I get too frustrated! Thanks for any help.
