![]() READ MORE targetblank data-wpel-linkinternalLaser Engraver this Knowledgebase Article is the perfect place for you to start (well, except for maybe the safety article ). We have done hundreds of hours of research on every aspect of these units and, with great input from many great people, have navigated through the initial rough waters of getting a poorly made Chinese clone of a machine to run far beyond our expectations. The reason I reference this unit in that manner is that my first experience with a laser engraver was spent on my ULS-25E. An American made, precision, workhorse that was built in 1991. But, I LOVE my K40 Lets get a few items out of the way from the beginning. Please, for the love of all that is holy, never refer to your K40 as the blue and white one or the orange and white one. Try to provide accurate descriptors andor photos when referencing your machine. These lasers vary greatly in build quality and require a good deal of tinkering to keep them going. If you dont like to tinker, if you are not at all mechanically inclined, or if this is a mission-critical business appliance you may want to find a US laser. The tube of goo (silicone sealant) is for insulating the high voltage connections on the laser tube and nothing else. Put it up for safe keeping. Take the included exhaust fan and ductwork out of the machine and very carefully place it into the nearest trash receptacle. Then see the alternatives below. Do not plug anything into the electrical outlets on the machine. Power (or more correctly, radiant flux) is used to express the output of continuous (CW) lasers and is measured in Watts (W). The average power from a pulsed laser is the product of energy per pulse (in Joules) and pulse repetition frequency (in Hertz). For example, if a giant pulsed laser produces 10 pulses per second (i.e. ![]() Magnusson Laser Measure Instructions Deutsch Install Air AssistLet me say that a different way: You MUST install Air Assist. There are many options and we cover a cost-effective solution in this article. Okay, now that thats all taken care of we can dig into the necessary initial modifications for a K40 to greatly enhance its performance and reliability. ![]() ELECTRICAL SYSTEMS The quality control for the wiring harnesses in these units is about as varied as the rest of the machine so great care needs to be taken to go through the wiring and make sure there are no bad terminations, loose lugs screws, grounding issues, etc These machines can be hazardous as far as the AC power and the high voltage Power Supply Unit A power supply unit (or PSU) converts mains AC to various AC andor DC voltages for the internal components of a device. Magnusson Laser Measure Instructions Deutsch Manual Switch ForSome power supplies have a manual switch for selecting input voltage, while others automatically adapt to the mains voltage.

It was initially designed to generate high voltage sawtooth signals at a relatively high frequency.
