Customer Reviews for Vevor CNC 3018 DIY 3 Axis Engraver Kit GRBL Control Milling Machine For Wood PVB PCB

So far I'm pretty impressed. Machine had nema 23 motors not 17. All the instructions can be found on the flash drive. Written instructions very limited. Need to change grbl settings after set up original speeds very slow. Only thing I don't like is the Z axis carriage very limited on spindle mounting options. Also all wires are a little short when you have limited room to put the control box.

Bought this one after returning what was to be a much stronger sainsmart 3040. After the letdown of that product I had almost zero expectations for this one. My expectation was for it hold up just long enough to cut parts for much stronger one I decided to custom build. I will say the directions are horrible at best, but after using it for a couple weeks I am impressed with it. Even using belt drive this thing can hold it’s own. I did ditch the spindle for a 72mm mount and a Bosch router with a 1/4” collet. Even still it has no issues with .5 mm step down passes on 6061 aluminum at a feed rate 500. So far it’s impressed me enough that my custom build remains a box of parts in the corner. I will point out that you need a seriously large area to set this up and if using fusion 360, disable helical arc in your post process and all will be golden

Great CNC for the price. Everything you need to get started is included.

The technical support is excellent. We resolved the issue.

So this is not a good CNC for someone just starting to learn. There are a lot of variables with a CNC machine, and there is a lot to understand in the process. These is an affordable machine For someone who wants to devote the time to learn the process and make mistakes. I have been running professional CNC machines for years, and this one can be finicky. The assembly is pretty tough, making sure everything is squared up is key! Locktite your screws, and watch for bearings coming loose, and you will be on the right track!

Great for learning how to use a cnc, the spindle has runout

It is easy to put together. There are youtube videos that walk you through the assembly. The hardware is cheap chinese so you'll want to swap that out. Its not easy to use and takes some set up and patience but the value is there.

The assembly is not difficult, if you have an issue, please contact them. They are very responsive and care about their consumer satisfaction.

Thought I would have to ream out all the nuts when I started, but picking up another pair I found I just had one bolt that was misthreaded. Fortunately there were extras.Recommend a muffin tin to hold all the parts. Purchase a square if you don't have one. Also, if you're not near your computer, print out the instructions. There are several YouTube videos out there, be sure to watch the one that closely matches yours.It went together well, and the software worked okay.Improvements would include having zero stop switches, and hardened tools, as mine stripped out fast.Looking forward to making a couple of upgrades, including the aforementioned zero stop switches, a cover for the board, and other printable upgrades. Came with a cute battery operated light, too. Can come in handy.

At this price point it is hard to complain! All the 3D printed parts have been replaced with nicely finished ABS parts. The 20-20 extrusions are well and cleanly cut, requiring minimal de-burring. The cast corner hardware isn't the best, best satisfactory. IT does have the rounded t-nuts that fit through the slot so that's a plus.The spindle motor is what it is. What will it cut? Think Dremel type power, but lower RPM. Would you use a Dremel to machine an aluminum/brass part? Probably not. It comes only with a steel ER11 collet chuck which is nice, but probably a little too much weight for this spindle. Earlier versions came with a simple brass coupler to hold bits. Although not as ideal as a tool holder, it would probably perform better.The included control board (Cronosmaker v2) and spindle holder support the laser module should you decide to add that later. The board also supports 6 end-stops,and a z-axis probe, none of which are included.The only real fitment issue I had was the x-axis lead screw that runs across the gantry. It inserts into a captive bearing on the floating end. The screw is small enough that it doesn't actually engage with the bearing, this rattles annoyingly. I wrapped that end of the screw with a couple of turns of Teflon tape which solved the problem.All the linear guide rod bearings are the typical Chinesium type, bone dry, and a bit crunchy. Gently flush them out with some solvent/cleaner and lubricate generously before assembly.After these small changes, with the spindle power off, the machine is running virtually silent. Nice and smooth.Rigidity isn't that great. Most of the flex seems to come from the small diameter x-axis gantry guide rods. The 20-20 frame is plenty rigid, I just wish the gantry guide rods were thicker. It doesn't take a great deal of force to flex and move the spindle carriage.You'll need to be creative to mount end stops (not included). 3D Printer is recommended for that.I would suggest making some sort of backing on
