Hi,
 
	Thanks again for reply. It happens on all movement effects when slowed right down.I've checked DMX output while running the shape and it looks ok.
 
	Just tried same on a different make/model fixture and looks loads better (still small amount of stepping but nothing too noticeable)so obviously something in the way the 5R is dealing with the information. I can get a good smooth slow scan on the 5R from a different console. 
 
	The Chauvet R3 Spot I tried doesn't home with shutter open so lifting the channel fader doesn't bring light up, is this an easy fix (or intended?)
 
	Thanks
