Axis deflecting while jogging in G54

If I remember correctly, I've checked this back then and the the column R showed 0.0000 for G54 and other offsets. Clearing and saving the offsets did not help. Only G10 L2 P1 R0 resolved the issue. But since then, everything works fine. I will let you know, in case it happens again.

were you reloading the table after saving it? this is what removes any previous offset that may be in cached memory even after storage location has changed i think.
