Just a little cautionary tale!

Recently,despite regular reminders, one of our students used our VL300 without switching on the extraction cart, resulting in a badly burnt lens. I ordered and fitted a new one without any problem, but after a short time the machine stopped cutting. I looked at the lens and found that this too had been ruined! The reason was that I had not spotted that the small hose connecting the air supply to the air assist cone had melted during the first incident & blocked the air supply to the cone. Result, one brand new lens destroyed and £250+ down the drain!

I guess the moral is after an overheat, check everything that might be affected, not just the obvious stuff.

Enter as much information about your CNC hardware and software as you can - it makes it easier for everyone to know what you're talking about then.
Thanks for sharing!
Also remember to never leave a Laser un-attended when it's cutting.

Quite true! Could you by any chance supply a replacement tube (just the tube, the needle valve & fittings are fine)?

The laser air assist tubing is just a piece of 4mm OD nylon tubing
