Hi Jason
That's the same setup I have - it was all pretty easy aligning everything (even at the extremities - mine is 1200x600mm). Sadly, they don't supply a barbed nozzle for the air assist for some reason - I have a spare right angle M5 quick release (6mm tube) you can have if you're desperate.
Your laser head is different, looks like maybe an 'upgrade' - the website on Coletech still shows my version. Did you get the 63.5mm focal length lens ?
If so, I think the spot size will be slightly larger than your 50mm version - it would be good to get some feedback on that.
One thing to be aware of, the mirror mount adjusters will jam if you mount them directly on a flush surface - you need to add a shim to allow the 'square' adjustment screws to rotate - mine were just 0.5mm plastic shims cut with scissors then the M6/M4 holes cut with a hole punch to suit.
BTW, how's you noisy Axminster extractor LOL
Cheers
Neil
