That's very interesting. I've just re-built my own machine onto a base with castors and in spite of checking the alignment of rails and ballscrews I have had to reduce the max speed from 9.0m/min to 7.8m/min after a couple of stalls. I had not thought that a small amount of rocking of the whole machine would have a negative effect on it's operation but may have to think again.
