Robin I do not necessarily need 1.5m/s. A decent laser like a trotec will run higher at 3m/s. Speed is important when rastering an image with the laser, not so important when cutting.

The manufacture of the slides suggest a max speed of 1.5m/s so I was just looking to see what rpm I would need to hit the max. In reality I think the laser head is too heavy to run at 1.5/ms so I would be backing off the speed until it looks about right.

The 3:1 reducer is part of the kit so I prefer to leave it in, I think the reduction also helps with the sudden changes in direction the xy is subject too.
