Never add lights or peripherals directly to the laser power supply. Relieving the power supply from extra load is a approach you should have in mind every time adding anything to the machine. To prolong your life on the PSU you can do a few fixes to help this out.ġ: Add ventilation to the small compartment where the PSU is located.Ģ: Tilt your PSU, to draw ambient temp in to the fan on top. Our K40 lasers has the same problems and the power supply is very sensitive. K40 laser power supply TemperaturesĪll electronic products have problems with heat, the more heat the lower the efficiency.
Read more about smoke assist here and here. I coined this term a couple of years ago, to get a term that describes the work of fans inside the machine. Read this bigger article about exhaust fans. The included fan is both dangerous and bad, it will partially do the work but there is much to do.
Sealing the machine will help keeping the gasses inside the case and out the exhaust, this can be done with duct tape, hot glue or silicone to seal the openings and cracks in the machine. Smell from the machine is both annoying and might be dangerous depending on what you cut. I would point at three types of cooling upgrades.ġ: Radiator in the water loop, to cool the water with ambient temperatures.Ģ: Peltier cooler, very inefficient but does the job – to a certain limitģ: Gas powered coolers, dedicated coolers like CW5000 or DIY built from a refrigerator. Read more about coolant types here Cooling upgrades If this process slows down you are using more “power” out of the tube than it regenerates and you will get a tube dying on you prematurely. Optimum coolant temperature is below 22 Celsius.Īnything above will slow down the regeneration-process inside the laser tube, where the gasses are recombined to new Co2. Make sure the pump is at the bottom of the tank and return-hose below water level. The included pump coming with the machine is good enough and will work as intended. If you live in a hot climate, you need a bigger tank to keep the coolant colder for longer, a small tank will heat up quicker. K40 laser water cooling Coolant tankĭepending on where you live, it might be a good option to have a bigger tank 15-25L or more. It´s far from perfect and needs a hand to work as you intended.įirst reading should be the article about checking your machine – K40 electrical warnings – first setup. The K40 laser machine is a awesome little product who makes it easy for hobby and semi-pro use to get going with laser cutting or engraving. Bed´s and jigs for the K40 laser machine.
