Vevor KH7050 Co2 Laser 80 watt - For the price, a massively and fantastic piece of machinery. The packing was very safe. The delivery was unbelievable. 4 working days shipment from Paris to Denmark. Ordered on a Friday evening at 8pm, and delivered following Thursday at 1pm.
The machine itself, is exactly as the description promised. It is a very sturdy and stabile constructed machine, and is almost completely similar to other brands of these types of lasers. Every aspect of this machine, appears and operates as a well build unit. The onboard computer is very tight and well responding.
However it took the good of almost 4 days to get it properly aligned, to achieve the full power and precision. Alignment from the factory was nothing less, but completely off.
All instructions on the delivered usb are in Chinese. Also icons, and explanations in videos and on text. Meaning You are not even able to compare icons from the video, to your screen. But, the delivered instruction booklet, is in English tho.
Luckily Lightburn was able to identify the machine, and did the necessary installations by itself.
The onboard water cooler is fantastic, and eliminates the need for external pumps, water basins or exposed hoses. For the jobs i have been doing so far, it keeps the coolant at 12 degrees Celsius, which is right between the recommended temperature gap, mentioned in the booklet. It requires 13 liters of demineralized water, to be in the sweet spot on the level gauge.
Cons on this machine - The extraction fan is WAY to weak, to keep the enclosed compartment free of smoke. I have ordered a large in-line blower (506 CFM - 200mm), which hopefully will do the job better. A fa so weak, would result in build up, of residue on rails and interior of the working compartment. Also result in need for cleaning very often.
Also the air assist seems to weak, for this size of laser. However i haven't got to test it firmly just yet. But if i am correct, and the pump shows up insufficient for the job, its a fairly small investment for a larger air assist pump. Perhaps hooking it up to a second line, from a stationary compressor would be preferable. The future will show
All together, a very nice product, insanely fast delivery, and the unit is what it claims to be, compared to the product description in the add. The price is nice for a product of this size, and compared to value/price in other brands. Similar machines, with exact same specs, controller and hardware can easily have a double or triple investment cost in this part of Europe.
