another small update ...
Machine is working wel

Issues I need to deal with ..

Smoke !!!
I he\t my workshop with a log burner .. and worrie about upsetting the neighbours ! I'm a fair bit away from them at the workshop, but the laser is making much more smoke than the woodburner !!! ... I didn't expect that !! ... will be figuring out how to deal with the, and let you know how I get on.

Cooling !
I'm using the laser a couple og=f hours a day at the mo ..water is typicaly 18deg in the morning. I can get a couple of hours cutting and it's up to 30ged ... which I don't want to go beyond. I have a cheapey thermometer with a temp probe I leave in the bucket.

imeadiate solution .. ice packs or froxen water in bottles .. or bigger bucket.

longer tme solutions .. second hand/freebie/recycled freezer .. modded with tubes/pipes etc.. to keep everything cool ...

will update as and when :)
