The last paragraph of the comment (i.e. "A cleaner fix ...") includes some suggestions on possible ways to do that. However, I think at some point you will come up against the rate at which the PMAC is being polled by the driver. I think this is 10 Hz right now. If you need to get that move time below 0.1 seconds, I think the driver poll rate would need to be increased. Lewis
