Setup was quick and very easy, this is actually the second I purchased because I like the first one so much. It is very user friendly even if you’re a beginner, it produces professional quality results. I purchased upgrades for this machine to include x and y axis extension and routers as well. I had one issue with one of my offline controllers but customer support was excellent and quickly replaced the defective controller. I am impressed with the quality of machine you get for the money, their customer support is also top notch. I did my first carve right after I received and assembled my machine, it performed better than expected, lower noise level than other machines I’ve used, the carve was very precise and detailed and the machine is very solid with no detected play I. Any of axis.

The media could not be loaded. I recently got this cnc yesterday and running a little quick job I ran on 2 different I had purchased and had to return. This cnc is absolutely great it runs very smooth and no movement in the spindle where it attaches to the gantry. I had bought a Lunyee couldnt get it to power up. Had bought an acmer cnc router while running the same little job as this one. The spindle kept twisting to the top right causing the job to mess up. This cnc is absolutely worth what they are asking for you will be be very happy with it. I cant wait to get started on bigger jobs with it and more define jobs with it

The unit is great. It was easy to assemble and there are a ton of YouTube videos to help with bringing it online. I intend to carve mostly hardwoods like Maple, Cherry and Walnut. It does a good job using a V bit but the excessive chatter with a 1/4" or 1/8" end mill bit makes a mess of the project when carving pockets or profiles. The unit I have had too much play in the X and Y axis simply due to the play in the spring loaded nuts that are driven by the lead screws. I was able to eliminate that chatter by disassembling the nuts, tapping some existing holes in the floating side to add set screws. This allowed me to carefully tighten the set screw until the backlash was gone but the lead screw could still operate freely. Added some loctite to prevent the set screws from loosening over time. Unfortunately, the spindle motor assembly that was supplied as well as the upgrade spindle with higher rpm also flex too much and the chatter is still unacceptable. The next modification will be to upgrade the spindle motor to a trim router to see if I get the chatter to stop. I'm overall very happy with the unit but I want to improve the performance. For the beginner, Easel Inventables software works great and is easy to use. The first 30 days is free but after that a subscription is required.

I purchased this machine on cyber Monday in 2023. I was looking for a CNC that had more stability, accuracy and repeatability than the belt driven machine I currently had at the time. I wasn't disappointed. The packaging was about the best I've ever seen, assembly was a breeze and it was square and level right away. The screw drive and linear rails make this quite rigid and reliable. I used it for about ten months when it stopped working. After contacting customer support and describing the symptoms it was determined that the power supply went bad. They sent me a new one free of charge which solved the problem completely. I can't say enough good things about the machine and level of support I received.

I’ve had it a year and never been able to load the software. Quality of the unit seems good but can’t use it

I received the machine in good condition, the packaging was superb,. unpackaged and assembled, clear directions. took around 30 minutes to set up. the software (Candle) that came with it is a bit lacking, but I use G-sender and V-carve Pro. This is my first desktop machine, so I am going to try my best to capture everything I have experienced so far. Pros: Good quality main frame, pretty stiff for a desktop Good packaging Great customer service Easy to assemble with easy to follow instructions Very quiet Cons: Extremely underpowered, most bits require 12000 or more rpm to work in optimal range, the spindle is only turning 9000 Upgrade parts are almost as expensive as purchasing a new machine( spindles, extensions Etc.) would recommend the 1.5kw VFD spindle or trim router if you will be carving anything thicker than 1/4" pine. The stock spindle struggles to cut though on profile settings, deep v-carves and 1/4" clearing pocket cuts. V-bits and End mills that have a 1/4" shank are unusable with the stock spindle. Very little adjustments to correct Tram and squaring Final thoughts: The machine advertises that it can cut wood, metal, acrylics and other soft materials, what they don't tell you is that the machine will not cut smoothly with 1/4" bits or anything thicker than 1/4" and that is testing the limits. All in all, it is a good starter machine, a little pricey for beginners, but bear in mind this isn't a commercial machine, if you are doing small carves with minimal depths this is a great machine. If you are seriously trying to carve heavier materials look to the more robust (and more expensive machines). If I can afford to purchase the 1.5kw VFD spindle I will return and revise the review. If Genmitsu/Sainsmart would like to donate the spindle set up, I will put the machine through its paces again, and give another review with the upgraded machine.
