I recently purchased the Vevor KH7050 laser machine, and overall, I have some important considerations to share with potential buyers. Pros: The machine arrived well-packaged, and the shipping was fast, demonstrating care and efficiency in the delivery process. In terms of value for money, it is a good option, especially for those looking for an affordable machine. Areas for Improvement: Customer technical support could be more effective. The extraction system and air assist need improvement. Without these upgrades, the work can come out dirty, and the workspace can fill with smoke, which is hazardous. Another critical issue is the lack of a rotary axis connector, which does not come with the machine but could significantly improve certain tasks. Important considerations for new buyers: While the price is attractive, it’s essential to know that additional investments are required to make the machine functional and safe: An air assist system to avoid dirty finishes; A cooling system to increase continuous work time; An effective smoke extraction system, as the built-in one is insufficient and could pose risks. Conclusion: The Vevor KH7050 can be a valid choice for those on a limited budget but requires additional upgrades to achieve acceptable performance. I recommend this machine only to those willing to invest in the mentioned add-ons.

Goede machine na een aantal aanpassingen. Eerst en vooral was de laser niet goed uitgelijnd maar dat heb ik zelf opgelost. De Luchtpomp is niet sterk genoeg en de luchtslang te dun. Die heb ik allebei vervangen. De luchtpomp was niet aangesloten op de controller, die begon al te pompen vanaf je het toestel opzet en je kon hem dus niet met lightburn uit zetten. Heb ik ook moeten aanpassen en een extra relais moeten kopen. De luchtpomp haalde zijn lucht van in het toestel waar de rook hangt met als gevolg hij blaast al de vuile rook op de lens. Heb ik ook moeten aanpassen. De Koolstoffilter die in het toestel zit die volgens hun regelmatig moet vervangen worden kan je niet vervangen of je moet redelijk wat losvijzen omdat de luchtpomp in de weg zit. Die heb ik trouwens helemaal verwijdert omdat anders de afzuiging niet sterk genoeg was. Na al deze aanpassingen ben ik wel tevreden van het toestel.

Robust and very easy to handle. 80w gives enough power for engraving in most materials and cutout in almost anything but metal. We have been using it for engraving and cutouts for marine instrument panels. It’s absolute necessery to compement exhaust with an extra fan and outdoor outlet for a smokefree enviroment around the machine. As a summary I can definitly recomend this buy.

Tuvimos un problema con la máquina al recibirla, el voltaje no era el correcto, la atención al cliente nos solicitó una serie de información y nos resolvió el problema de una manera satisfactoria para las 2 partes. Recomendaría comprar en esta página, ya que lo que más miedo nos daba era el servicio postventa y ha sido de 10.

Mooie machine, werkt goed met LightBurn. Ik had een probleem waarbij de X-as niet werkte, maar dat was mijn fout; de knop voor de rotorfunctie stond aan. Daarna heeft de machine drie keer goed gewerkt, maar op de dag van de aflevering stopte de laser met branden. Het figuur werd nog steeds mooi op het scherm weergegeven, en de kop maakte de juiste bewegingen. De helpdesk is behulpzaam, maar houdt me al een week aan het lijntje, en de laser werkt nog steeds niet. Ik heb de software opnieuw geïnstalleerd, zelfs op een nieuwe laptop, maar het heeft niet geholpen. Zelf denk ik dat de hoogspanning los zit of dat er iets anders aan de hand is. Vandaag moet hij retour, ik ben er klaar mee. Goede prijs, maar dat zie je ook wel terug in de service en bouwkwaliteit. Nice machine, works well with LightBurn. I had an issue where the X-axis didn’t work, but that was my fault; the rotary function button was on. After that, the machine worked well three times, but on the day of delivery, the laser stopped burning. The figure was displayed nicely on the screen, and the head made the correct movements. The helpdesk is helpful, but they’ve been stringing me along for a week now, and the laser still isn’t working. I reinstalled the software, even on a new laptop, but it didn’t help. I suspect that the high voltage connection is loose or that something else is wrong. Today it has to go back; I’m done with it. Good price, but you can see that reflected in the service and build quality.

La verdad que la calidad precio es muy buena. No pongo maximo en todo porque el servicio de atención es un poco lento y a mi me resulto un poco tedioso. Pero vamos en definitiva que si que volveria a comprar este producto. Espero que dure bastante. Gracias

A maquina faz o trabalho a que é destinada, veio com os espelhos alinhados, tem boa qualidade no corte e faz uma boa gravação! Recomendo a quem esta a começar e a quem tem curiosidade de explorar a área da gravação e corte laser!

Der Laser kam gut verpackt, wenn auch nach sehr langer Wartezeit, bei mir an. Ein paar unerhebliche Schrammen tun der Funktionalität nichts ab. Nach dem Aufbau konnte theoretisch sofort losgelegt werden. Einzig der Wassertank fässt, entgegen der Beschreibung nicht nur vier Liter, sondern rund 20. Das führte zu einigen Wegen mehr, um destilliertes Wasser zu besorgen. Der Einbau neuer, hochwertiger Spiegel gestaltete sich als leichter als gedacht und es musste nicht einmal mehr nachjustiert werden. Da wie bei fast allen günstigen Lasern das Netzteil mehr Spannung liefert, als die Röhre aufnehmen kann, wurde von mir ein Amperemeter eingebaut. Bei meinem 60Watt-Laser entsprechen 18mA einer Laserleistung von 50% im Programm (LightBurn) und sind nicht zu überschreiten. Ein Abstandsmesser zur Einstellung des Fokuspunktes wurde zwar mitgeliefert, aber bei der Überprüfung stellte sich heraus, dass der Fokus nicht dem entsprach (Kleinigkeit). Mein Hauptkritikpunkt liegt in der Konstruktion der Umluft und dem Air Assist. Anfangs funktionierte der AirAssist nicht. Dies war, wie sich später herausstellte ein Hardwareproblem, aufgrund ungünstigen Verbauens der Komponenten. Das Problem konnte zufällig durch mich gelöst werden, da ich mich dazu entschied, den innen liegenden Filter auszubauen. Dieser verhinderte nämlich eine vernünftige Absaugung aus der Laserkammer. Also hintere Klappe abmontiert und Filter raus. Dabei fiel auf, dass der Filter den Schlauch zum AirAssist abklemmte. Also nachdem der Filter raus war, funktionierte alles tadellos. Der Filter kann weiter genutzt werden, indem er einfach von außen am anderen Ende des Abluftschlauchs angesteckt wird. Einzig der Anschluss vom Abluftschlauch an das Gehäuse war ein Kampf. Alles in allem hatte ich an diesen Schraubereien aber meinen Spaß und bin hinsichtlich der Funktionalität, Genauigkeit und Qualität sehr zufrieden. Zu diesem Preis einfach unschlagbar! Vor dem Kauf unbedingt überprüfen, ob der Laser durch die Türen passt ;)

I have not set up the machine yet as I noticed minor damage to the crate and the control panel does not sit flat uniformly upon uncrating. I am awaiting vevor to contact me. The machine also sits quite low to the ground a set of legs to lift it about 18 inches higher would be nice but I will make those myself. Other than that I will make a new review after I have been able to put it to work.

I'm giving it 2 stars (even though I'd rather give it 1), because this machine did at least help me learn. What can I say... I bought it when there were still very few reviews. A 100W CO₂ laser seemed like the perfect way to start producing my own projects and stop relying on my usual supplier. Looking back, I can say without any doubt that it was a big mistake. Let's start from the beginning. The machine arrived with a crooked gantry and mirrors that needed complete alignment. The tube exiting the head was welded crooked and wasn't even close to being perpendicular to the workbed. VEVOR replaced it at their expense, and I do give them credit for that, but the replacement was just as crooked as the original. I was only able to achieve a slightly perpendicular beam after replacing the entire head assembly with different components and adapting them myself. As many other reviews have already mentioned, several cables were not properly secured, and the screws for the panels, mirrors, and linear guides strip almost immediately. The installed laser tube was manufactured in late 2023, and even today, after only one year of ownership, the beam visibly flickers at low power. The nozzle also produces an almost electrical buzzing sound that is not caused by the air assist or by the beam touching the nozzle tip. I had to remove the stock air pump, install a proper compressor, add an external chiller, and replace the blower because the factory setup was simply not adequate for reliable production work. After comparing my results with other CO₂ laser users, I also have serious doubts about the condition of the power supply. Even after just one year, I cannot achieve results comparable to machines using the same tube, power, and cutting speed. Today, despite countless hours spent calibrating the mirrors, X-axis, Y-axis, and laser tube, I can only use about one quarter of the working area, the upper left corner, roughly 38 × 38 cm. Anything I cut outside that area is likely to come out skewed or full of defects. I've spent countless hours, and months of my life, trying to make a machine work properly when it was probably defective from the factory. The only positive thing is that I now have a very solid understanding of CO₂ laser cutting. It's just a shame I learned it by repairing this machine instead of using it to produce. ++EDIT after VEVOR commented on this review: NO, the issues were never actually resolved, and the machine was never made to function properly. After the second set of replacement parts was lost in transit for months, VEVOR simply offered me a refund, which I gladly accepted out of despair. I then had to continue looking for a solution BY MYSELF. The laser clearly had manufacturing defects from the start.
