Man Im gonna tell you, when it rains it pours with our Fadals. My current problem is the Y axis is jerking. It completed a part just fine. I went to jog the machine and the Y axis was jerking bad. It acted as if no lube was present on the ways. So i pulled the covers and it is indeed oiling. When I change the jog speeds, it becomes more pronounced. If the jog speed is slow, the jerk is low and pronounced. When you speed it up, the jerks occurs more rapidly. You can feel it on the table. So what do you think, drive card or servo. Keep in mind that this is a Numatix retrofit. The control has been running awesome, so I dont see that as an issue.
Thanks
Edit: I tweaked on the comp pot a little bit until it shook like crazy. I then hit the e-stop to stop the shuttering. I then adjusted the comp pot to the oriinal setting and it is now as smooth as ever. Go figure. If anyone has any ideas as to the cause, please post.
Thanks
