It should be at the bottom of the bucket. The Wonderful Aquarium Pump – This is only above the water line for the photo. The tubes in my laser cutter were already filled with water (?) which naturally leaked everywhere during shipment and the control panel shows evidence of being wet. The output tube from the laser cutter can be loosely hanging into the reservoir. The pump is supposed to sit at the bottom of your water reservoir where it draws in cool water through its vents. So just to make sure, the water input on the laser cutter is connected to the pump output. It was correctly labeled on my laser cutter but if I just followed instructions blindly I’d probably have a broken laser tube. In the manual, the input was on the opposite side that it was supposed to be on. Overheating it just once can and likely will be enough to kill it.Īs for the connections, my instructions had it totally backwards from how it was on my laser cutter. If you notice the water is getting too warm then either quickly cool it off or stop the cutting process. We all know what happens to hot glass when you fill it with cold water. Make sure to use distilled water or at the very least purified water. It doesn’t hurt to add frozen ice packs or ice cubes if the water starts to get warm during operation but remember not to get the water too cold. As a lesson in heat transfer, the more cooling water you have in your reservoir the more heat you can absorb so it benefits you to have your bucket nearly filled. I use a 5 gallon bucket from Home Depot but anything that can hold several gallons of water should be fine. It’s not even a very good aquarium pump at that. My first thought was “This can’t be an aquarium pump can it?”. Laser Tube Compartment – Note the sticker that I could not remove They also put a sticker on the laser tube which I don’t think was a good idea since I couldn’t remove it. I removed it but I’m about 80% certain this would have been an instant fire had I not since it was actually blocking the laser path. Just out of curiosity I opened the laser tube compartment and noticed it was filled with bubble wrap. Although I feel it was necessary for shipping, it’s not necessary to keep the screws there. There was a screw holding the laser tube compartment shut as well as the control panel compartment. Fan Sits Loosely Leaning Back – I removed the vent duct for the picture There is another model (minor upgrade) that provides an aquarium air pump which blows air onto the work piece and prevents smoke from interrupting the laser path. It also helps the laser to cut without interference from smoke. It’s only to remove smoke and avoid poisoning everyone in the same room. I feel like it’s a popular misconception that this fan was provided for cooling the laser or mirrors. I have no idea why they thought this was acceptable. As a designer if I couldn’t have found another fan that fits, I probably would have increased the height of the laser cutter. I’ve seen others like this so I guess it’s normal although unsightly. The fan actually sits slightly above the top and leans back. Next I notice the exhaust fan is too tall for the laser cutter. It was not off to a good start Mangled Vent Duct It’s still perfectly functional but it’s not a good sign to see something bent and crammed carelessly into your new toy. That being said click below to read on.įirst of all, I open the laser cutter to find my vent duct completely bent. A laser cutter is a powerful and dangerous tool and it’s not a toy. I’m writing from my experience only and I’m not responsible for any damage you cause with information you’ve read here or anywhere else. Understandably, this is going to frustrate people who shelled out a few hundred dollars to purchase this machine so I figured I’d be the one to do a write up and potentially save you some headache from my experience. You might see some reviews or complaints but there is very little information about its operation or maintenance. Try to search online about the” 40W Laser Cutter”, “Chinese laser cutter”, “eBay Laser Cutter” or “K40 Laser Cutter” for information. Being that I’m a mechanical engineer who is used to accurate documentation, this is just deplorable. In addition, the pictures in the manual were inaccurate and there were various ports/connections in the manual that just were not on my model. The manual (at least the one I received) is written in poorly translated English and it really just skips over many important functions of the laser cutter. Overall this is a good machine but it leaves a lot to be desired and the quality control is certainly lacking. I’ve had my 40W Laser Cutter for just over three months now and I feel that I’ve got a good grasp on how it operates.
