Sky Watcher Esprit 100 Focuser

[sws105]

I just got a new Sky-Watcher Esprit 100.  Seems I have a little play in the focuser.  It’s a little unusual as the draw tube move about 1-2 millimeters either direction before fully engaging.  It’s not really backlash because the draw tube is moving, just not fully engaged. I have not experienced this with any of my other rack style focusers.  Any insight is appreciated.

Do you mean the focus knob turns 1 or 2mm in either direction before engaging? It's rack and pinion so I can't see how the drawtube moves unless something is very loose. The fine focus knob is a kind of Crayford style mechanism so that can slip but the course focus is direct engagement with the rack so that shouldn't slip at all.
