#LASERDRW WORKSPACE SIZE SERIES#

We plumbed it in series with the OUTlet tube feeding back to theВ reservoir so we have a more accurate measurement of the coolant temperature inside the laser tube and not the ambient temperature of theВ reservoir.ДЄny smoke, fumes, etcвЂ¦ generated by the lasing process is dangerous.

#LASERDRW WORKSPACE SIZE PC#

To monitor the flow and temperature of the coolant we chose a cheap and simpleВ flowmeter/thermocouple kitВ made for PC cooling. This is my recommended method because believe it or not, our K40 was PERFECTLY aligned right out of the box so we did not have to spend one second on realigning the optics! IвЂ™m glad we didnвЂ™t tear it apart for a bubble. We found that simply and CAREFULLY tilting the unit around (with 2 people) until the bubble was evacuated solved the problem. There have been many posts on this issue and the solutions range from letting the pump run 48 hours to disassembling the machine and вЂњshaking itвЂќ out of the tube and everything in between. Often times there will be a large bubble at the top of the tube near the outlet. There is a secret recipe and lots of other great info on coolants and additives HERE. Many additives will cause the laser to arc or вЂњshort downвЂќ and corrode the cooling system components. You also need to be very careful of the additives you choose to address freezing and algae. It is not very robust so we are looking for a more suitable replacement.Дistilled water should always be used as it is less electrically conductive than tap water. We are using a 5-gallon bucket with a lid for ourВ reservoirВ and have, for the time being, retained the water pump that was included with the engraver. There will be more information on the electrical system coming soon. We are using a commercial aquarium pump that has a relatively low current draw. We did, after checking the wiring to these outlets, decide to hardwire our air assist pump to the feed for one of the outlets since we mounted our pump inside the chassis. The main power for the laser engraver needs to be a dedicated outlet with a rating of at least 15 Amps. A well made, surge protected plug strip is highly recommended for the accessories, upgrades, and peripherals. The вЂњoutletsвЂќ provided to power the water pump and exhaust fan are not suitable for use. 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, etcвЂ¦ These machines can be hazardous as far as the AC power and the high voltage power supply ( flyback) goes. YOU CAN FIND A DIAGRAM OF OUR SETUPВ AT THE BOTTOM OF THIS ARTICLE. Okay, now that thatвЂ™s all taken care of we can dig into the necessary initial modifications for a K40 to greatly enhance its performance and reliability. There are many options and we cover a cost-effective solution in this article.

#LASERDRW WORKSPACE SIZE INSTALL#

Let me say that a different way: You MUST install Air Assist. They are poorly designed and poorly wired. Do not plug anything into the вЂњelectrical outletsвЂќ on the machine.

Take the included exhaust fan and ductwork out of the machine and very carefully place it into the nearest trash receptacle. The tube of вЂњgooвЂќ (silicone sealant) is for insulating the high voltage connectionsВ on the laser tube and nothing else. If you donвЂ™t 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.Д¤. If that sounds fun to you then you will love it!ДЈ. These lasers vary greatly in build quality and require a good deal of вЂњtinkeringвЂќ to keep them going. Try to provide accurate descriptors and/or photos when referencing your machine.Дў. Please, for the love of all that is holy, never refer to your K40 as the вЂњblue and white oneвЂќ or the вЂњorange and white oneвЂќ. Please make note of these observations and suggestions:ДЎ. LetвЂ™s get a few items out of the way from the beginning.

An American made, precision, workhorse that was built in 1991. The reason I reference this unit in that manner is that my first experience with a laser engraver was spent on my ULS-25E. 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. If you are considering buying, or have just purchased a K40 Chinese Laser Engraver this Knowledgebase Article is the perfect place for you to start (well, except for maybe the safety article).
