Oh it gets up to 30. Actually, I've had it up to 32 IPS, according to
Halscope, but this test had the max velocity set to 30. I hav

If confined to a single axis move,there should be none.
Unless the accel and decel ramps should differ between the two move types?

I made a short video of progress in tuning my Linear Motor axis. This is
going to be the Y axis of a laser machine. In the video, it's doing a series
of random rapids at 30 inches per second, or 1800 IPM. During these rapids,
the FE is less than 0.05 inches. I'm not done with the tuning yet, but th
