First Scanner (RGY)

Very easy and it loves high speeds. The only problem is that the bits tend to stick to the tool if you don't have a carbide tipped one. Use Diesel fuel to prevent it. Also applicable for threading tools.
Magnesium alloys are even better and lighter but harder to find.

Ehh... I use ethanol when i drill or make threads in aluminium. It works great to lubricate and prevents the material to stick to the tools. A LOT less messy than diesel as it just evaporates and completely dissapears by itself...

Very useful information. Can you detail a bit, what concentration ?
((another major advantage is that it saves the money for the drink after finishing the work; we can drink the lubricant instead ))

I got a 16 x 12 x 1/4 " aluminum plate. I'm using it all plus I'll have to add a sub floor for power supplies and whatever.
I have white and am mounting the galvos now. Allignment is proving to be a bItCh !!!!!

My Dicro set from Bridge runs G, R, B -- I need all the red I can get using an LOC.

Hi Mille,

Just another thing:
Your case will be closed completely if it's finished, is it?
The two used fans are not working if mounted according to your pics.
They are all blowing inwards or all blowing outwards.
This is wrong, one must blow in and the other blow out.
It's the only way to create an airflow in a closed case.

Ehm i think you got the wrong person

Yes, I mean Steve Milani, the other laserist from Italy.

Well I use a kind of rubbing/fuel/denaturated type of alchohol. I think it's about 95% ethanol. Try it the next time you are drilling/cutting/threading aluminum. It is VERY effective as lubricant and makes everything a lot easier. AND there is no need for cleaning up afterwards! By the way: I think you would get sick if trying to drink this stuff...

Oh, one more thing. Used LOW speed when drilling. Otherwise the alchohol will just fly of the drill, and aluminum will stick to it, and everything will get uggly, and all hell will break loose when you destroy the piece you been working on for the last 3 hours, and, and, and...

Hi Mamba!
Glad to read you.
You said right. One fan blowing inside, another one blowing outside.
This is one of the possible and logical solutions... but...

While I was mounting fans I thought: the output hole, in the front, has not any glass, it is "open-to-air".
Well... I put two fans that blowing inside, so I force the warm flow of "exhausted" air to go out through from the frontal hole
I also thought: doing so I can have optics and mirrors always clean because smoke, dust and other dirty things cannot enter through inside from the frontal hole because would be "countercurrent" .
In fact with two fans that pumping air inside, the case is like "pressurized" toward the outside
I hope to have explained well the concept.

Kindest Regards and a perfumed rose to you for gift.

Ok i have another question
How do you adjust height in laser modules and optics?

Better to set everything at the same height with additional plates, or simply adjust heights and collimate the beams with mirrors and dichros?
