Fun toy

Nice DIY laser setup. Up and engraving in 2 hours or so. Overall happy. Some assembly issues but nothing major. PCB mounting was not great, screws were too long and needed some washers. Drag chain mounting is also problematic and hits y axis slide, need longer bracket.

Great Laser for the Price

I gave this a 5 star rating because there was not an option for 4-1/2 stars. I would deduct 1/2 star because of; (1) The assembly pictures are great but there are several steps that need better details (or more pictures). For example: how to attach the ends of the timing belts, which way to position the stepper motor connectors when mounting them & when to attached the laser head circuit board is not even mentioned. And there is also no mention anywhere in he instructions about the included thumb drive that has the software on it. (2) I also found that the v-groove bearings will not turn if you tighten the end nuts enough to keep the nuts themselves in place. If you loosen the nuts enough for the bearings to turn there is too much play and the carriages do not run true in the carriage rails. This was allowing the laser beam to move over 1/16" out of line from end to end. I solved that problem by replacing the end nuts with M5 Nylock nuts. That allows the end nuts to be tightened just enough to take the play out and still let the bearings turn and the Nylock nuts won't vibrate loose. But overall it is a great deal for the price and you shouldn't be buying/assembling kits if you can't figure little issues out for yourself. I am VERY happy with the machine and would definitely buy it again. Genmitsu LE5040 CNC Laser Engraver Machine Review

I'm having fun with this kit

Over all I am having fun with the LE5040 kit. The packaging was not as good as it should have been. The anti-static bag containing the laser had burst open and the laser was free to wander around a little. The same thing happened to the safety goggles and one of the stepper motors had a little fun scratching them up. I reported this to SainSmart and they are taking care of the issues. I was able to get the kit assembled in under 2-1/2 hours and that included video taping what I was doing. There is a major step missing in the instructions and I was able to figure that one out before SainSmart was able to get back to me. I have posted my assembly video on the CNC @ Home YouTube channel: I also have a short modification video to deal with a couple minor issues: I have not done much cutting with it yet. My first project turned out nicely. I have added a picture of that. I would recommend using this or any other laser in a well ventilated area. Cutting leather produces a not so pleasant smell; unless you like the smell of burning flesh. If you are interested in learning how to do CNC laser stuff, I would recommend this kit. It doesn't break the bank and everything you learn is a transferable skill when it is time for you to upgrade. Genmitsu LE5040 CNC Laser Engraver Machine Review

Very cool little laser

Just received this on Saturday and started building it pretty quickly. Here are some of my notes from the build and first time test of the LE5040. Cons: -The instructions are good, but can be a bit difficult to understand. For example, when trying to setup the belt tighteners, it was a bit difficult to fully understand how they had set it up. I had to look at a close up of the picture on the website to see how they installed them. (This is why I gave it 4 out of 5 stars) -The parts were not labeled on the individual bags. This made the build go slow as I had to lay everything out and guess what bolt size we needed. Pros: -This device scream in terms of how fast the X/Y motion is. Compared to the small 3018-PRO, this device can run circles around it. -The 5.5w laser works quite well and with this setup, it functions as it was designed. -The work area that this device can utilize, especially for a well priced device, is phenomenal. -This device does come with an off/on switch on the mainboard which alone puts it past the 3018-Pro with the laser option in my opinion. -Very light weight. Overall, my view of this device is that of astonishment. The speed of the laser, the work area, and the overall construction of this engraver is top notch and worth the money for anyone interested in getting started. I would definitely buy another one.
