Twotrees TTC450 Pro CNC Router Machine with NEMA 57 Closed-Loop Stepper Motor 3.5" Touch Screen,Upgraded 3 Axis Engraver Machine, Engraving Milling Machine for Wood Acrylic Aluminum Carving Cutting

It has a bit of a learning curve but it’s worth it

The machine arrived quickly and setup was fairly easy. I did have some issues with the on/off switch, but replacement parts were sent by the seller to remedy the problem. I’m still learning to use it, but it makes good cuts and I’m sure it will be even better as I get better at using it.

- Fails on Basic Accuracy I purchased the TwoTrees TTC450 Pro from Amazon and returned it within a few days due to its unacceptable lack of precision. A CNC machine has one primary job: to cut accurately. This machine failed on the most basic test imaginable. To check its accuracy right out of the box, I programmed a simple cut: two identical straight lines, both specified at 3/8" wide and 2" long. I arranged them in a simple V-shape, starting from the same origin point but heading in different directions. The result was a clear failure. One of the cut lines was visibly wider than the specified 3/8" dimension (see picture). For a machine to produce two different-sized cuts from two identical lines simply based on the direction of travel indicates a fundamental flaw in its mechanical stability or calibration. If it can't handle a simple straight line, I have zero confidence it can produce anything with the precision required for actual projects. I didn't bother with further troubleshooting; a brand-new machine shouldn't fail such a fundamental test. Thankfully, the Amazon return process was straightforward. Hoping my first experience was a fluke, I ordered a second machine directly from the manufacturer during a sale. Incredibly, it had the exact same imprecise cutting problem, but even more profound. This confirmed my suspicion that the issue is a fundamental design or quality control flaw, not a one-off defect. My experience with the TwoTrees TTC450 Pro has been a month-long saga of disappointment, starting from the moment I opened the box. The problems began immediately: Missing Parts: The machine arrived with missing M3x5 screws right out of the box. A minor issue, but a clear sign of poor quality control. Mechanical Failure: Shortly after, I discovered a critical mechanical failure. The Z-axis motor would spin, but the bit holder wouldn't move up or down due to a faulty coupler. The Deal-Breaker: Even after addressing the coupler issue, the machine's primary function is a complete failure. It cannot cut accurately. Test cuts of two identical lines resulted in two different-sized cuts, one of which was larger than the design file specified. A CNC that can't cut to the specified dimensions is essentially a very large, expensive paperweight. Dealing with TwoTrees' "customer service" was even more frustrating than the faulty machine. Their strategy is one of delay, deflection, and making the customer jump through endless hoops: Slow Responses: Nearly every email from them took days to arrive and began with "Sorry for replying so late." Constant Demands for Proof: For every single issue, I was required to send photos, videos, original design files, and g-code files. It felt less like troubleshooting and more like an interrogation designed to wear me down. Refusal to Accept a Return: When I formally requested a return (well within their 30-day policy), they ignored the request and instead offered a "complimentary set of milling cutters" if I would keep the broken machine. The Return Runaround: After I insisted on a return, they presented a convoluted process requiring me to take more photos and videos before they would even provide a return shipping address. After sending the photos, I was told to wait longer while they "confirm the address with the warehouse." To make matters worse, the issue is still unresolved. It has been weeks since their last email, and I am still waiting for the return shipping address they promised. They have gone completely silent, seemingly hoping I will just give up. Save yourself the immense headache. Look elsewhere!

Great machine

This is a great machine that I picked up to learn CNC, and it has definitely served its purpose. As a total beginner, I didn’t have to worry about breaking it while figuring things out. In many ways, it feels like paying for tuition—I get to experiment, make mistakes, and improve my skills without breaking the bank. The machine is sturdy, pwerful, responsive, and so far has held up well to my clumsiness and trial-and-error approach. I’ve mostly worked with wood, and it handles that nicely. The noise level is tolerable, even in the city, as long as you’re running it during the day. The learning curve is steep, just as I expected, but that’s part of the process. At this price point, I think it’s a bargain and an excellent entry-level CNC. It gives me the freedom to learn and create without fear of ruining an expensive machine.

The build quality seems very sturdy, it's not too loud, but the functioning of the machine is not great. It's not very hard to put together but there are several pieces so it does require some level of handy ness. The overall engraving is not what I would hoped from a $600 machine. It's kind of hit or miss actually. There are several upgrades that you can buy for this machine that I have read about that make it in an outstanding machine but unless you're willing to drop a couple hundred more dollars you might want to look elsewhere at this price point

This machine is so impressive and such a wonderful value, I feel like I have gotten a "business in a box"! This CNC router is a woodcrafter’s dream. It looks sleek and modern and has an 18.11” x 18.11” x 3.15” working area and a 3.5” touch screen, so everything feels very very hi tech. The capabilities are so amazing, it’s like having a mini factory on your desk. I have re-enrolled myself in YouTube University to learn to carve a custom jewelry box. I've seen videos of people working on similar machines and every detail came out so crisp and precise. From hearing other woodworkers talk about these machines, the specs for this one are very impressive. The router has 800mm/min speed which is fast enough for efficiency but not so fast it scares you and with that much power, the spindle glides along acrylic, MDF and even soft metal. I haven't made anything yet. I am still watching videos and learning because WoodWorker YouTube is.... mesmerizing. I am very excited though because although it seems that the learning curve is steep if you’re new to CNC, this wonderful, well-built, looks like it costs a million bucks machine is versatile, powerful, precise and incredibly satisfying for making custom projects. I give it five stars just for the quality and I will update the post with some pics when I make my first project!
