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

I was having trouble getting a replacement motor for the y axis on my Fox Alien laser engraver. Since they don't publish part numbers or motor data I had to go old school and found the info I needed and this motor was a perfect replacement. Only thing is you might have to reverse the motor leads depending on which side you use it on. I'm very pleased with my purchase.

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

Great machine

Funciona bien en Artillery x2

Good motors have had no issues with them and will buy again.

- 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!

Setup instructions were fairly good. Could have been more clear with better pictures as to where some of the wires plug in. I’ve only cut out one project, and it seems to cut a little rough…probably a learning curve for an amateur. The on/off switch won’t turn it off. I have to unplug the machine for it to go off.
