50W CO2 Laser Machine Unboxing, Review, Modifications & More

You want deionised water and some sort of anti freeze that can inhibit corrosion and algae growth etc. I use a chiller and the hpc antifreeze, but will only change my water every 3 months or so

just 'salvaged' the under counter freezer from our kitchen .. It's not been used for about 7 yrs as it cut out some times ... problem was likely lack of ventilation from the sealed run of cabinets and appliances it was housed in ! :/

I plan to fill it with 2L pop bottles filled with water ... as a cold store ... then run a micro bore copper tube (I already have) as sort of a coil ... but to fit where I can ...

I can't see why it wont work ?

Industrial water chillers are plenty £££'s ! ... so I'm hoping to save :) ... hopefully I can use the same set up for my water-cooled spindle too :)

Pics will follow :)

How are you getting on with your laser, I have been thinking again about buying one of these machines?

It has served me well so far .

I'm just upgrading the tube to 60w as the 50w original tube is about worn out.
It is about 1 foot longer, so will need to take advantage of the removable panel on the side, so the new tube will "stick out" a bit.
An enclosure will be made to protect the tube from me, and me from the tube !

Cool glad to hear she is doing you well. I was really tempted but in the end I bought some parts from aliexpress to rebuild my old laser.
