Hi guys. I’ve had my laser for 12 years and done little upgrades over the years. It was running laser cut 5.3 so upgraded to use the ruida controller. The one thing I hate is the laser pointer. You need to bend it sometimes to make it in the laser burnt dot. Can I upgrade the head on mine and also the pointer instead of just getting another new pointer?
The laser is a laser script 6090 60w
There are enough variations on machines, particularly in the last decade, to put “upgrade the head” into the realm of wishful thinking. I’d expect even an exact replacement would require significant shop time for tasks like nudging its mounting holes to match the belt carrier …
Maybe dismantle it and force the metal pieces into a bowl of brake cleaner out on the driveway? 
If those wires carry 5 V to the red-dot laser, you can replace it with any cheap-ish laser module, including a crosshair if you so desire.
The red-dot laser holder on yours is different than the one on my otherwise similar laser head:
I 3D printed the orange ring to simplify fine adjustments. You’d need something slightly different, but maybe you can fit a slightly angled mount into that bent sheet metal.
With red-dot modules (still) priced under a buck apiece in lots of ten, you can afford a few mistakes.
12 years is a fine lifespan for a laser, congratulations.
Is that air hose your primary compressed air supply or do you also have a hose in the nozzle head?
Regarding the laser pointer, mine is mounted in the same style as @ednisley , but instead of the nice plastic thing I have mounted a wooden disc with a pin hole to center a little better. Power supply for the pointer is original 5V.
There are many who think it is some unnecessary crap but I am satisfied with mine and even use it to focus the laser itself.
I’ll have to have a look at those style of laser pointers. Shouldn’t be too hard to fabric and get working. The heads ok. Like you say maybe a good soak in brake cleaner will do the trick
12 years is good. It is like triggers broom mind haha. Once I have this market out the way then I’ll give it a good going over. That’s not the original air hose. The original goes in the side but I found that the pressure wasn’t enough to clear the debris. I constructed that out of some pipe and squashed the end to make it more directional and have a little bit more power. Heads I’ve seen in other lasers seem to clear away so much more efficiently. Might see if upgrading the silicon hose to solid might work
That’s how I saw it in your picture too. But I would be a little concerned about not having a little bit of airflow under the lens in the nozzle, to keep it clean. On the other hand, if you’ve been running this way for many years without dirty lenses, then it should be ok. 
Yeah that does happen. I clean the lens more than usual. The airflow has never been that great on it. The hole in the cone is pretty big and would love a more narrow one. Might get the one made on the lathe
A small compressor of the type that the machines come with from the factory, fulfills the task of delivering a small overpressure in the nozzle, perfectly. The small compressors are not optimal for cutting operations but fine enough to keep the lens clean, I do not experience really dirty lenses.
I did upgrade my air to a more powerful one. Did make more difference. Might give the old girl some new lenses and stuff
