The firmware was the same, downloaded a month ago. The cable is provided by Mesa, no damage observed.
Today is even "funnier": the machine started to drift away, like user said, to go to completely different position than commanded in G-code. This was observed at least four times. Two of them where going to the material - operator noticed and hit the Emergency button. I think it is drifting away with the latest analog command DACs received and Enable signal state and all components: LinuxCNC, Mesa cards and servo drives are happy with it, not stopping anything and not issuing an error in a timely fashion. You can see the videos and pictures by yourself. The user claims it is the same G-code, almost the same time, no HW / SW changes, cables also not touched. Maybe even without LinuxCNC restart: https://www.youtube.com/playlist?list=PLMTctt_8ZIjX3eo2pw2IDmmH3Q34qZm83 The pictures of electric cabinet, cables, cards: https://drive.google.com/drive/folders/0Bx5r7yxJ8GWDTVdvbnFxVFFyYmc?usp=sharing 04/24/2017 03:23 PM, Peter C.
