Well, that was fun :)

The one thing i did not check was the run of the cooling pipes :)

I fitted the water chiller and filled it up, waited for leaks, waited a bit more, looked round the tube-ok, wen't to get a coffee - come back and the alarm is screaming and water is now over the workshop floor and streaming out the bottom of the cabinet :)

After mopping up, it turns out there are no ty-wraps or clamps on any pipes and it had blown off of the flow switch inside.

I've fitted ties everywhere now and refilled, the bottom of the cabinet is surprising water-tight and also full of very sharp corners :(

Since then it has burnt its first hole in card and i'm now running up some test shapes in RD.

The mirrors are filthy and the first check i did at mirror 3 shows the beam not to be very well aligned but i'll leave for a while and do some playing about.

I have also fixed the table up/down buttons.
