VEVOR CNC Router Machine, 3018-PRO w/GRBL Offline Control, Limit Switches & Emergency-Stop, PCB PVC Wood leather Engraving Machine, Dustproof Safe Acrylic Baffle, XYZ Working Area 300 x 180 x 45mm

Muy buena para trabajos de escritorio. Ya viene la mitad armada, y con un poco de paciencia es fácil de hacer las conexiones.

La CNC livre ce qu'elle a promis de livrer. Qualité semble bien.

Great way to acquire base parts, but dont expect quality assurance. Manual provided only covers assembly of physical structure, Not wiring or controller itself. Thumbdrive provided was a crap shoot to test your logic skills.Frame was assembled wrong from factory. Had to disassemble face plates rotate to have the sensor mounts in correct spot.The Motherboard would not function properly. Limit Switches would stop the axis, but not release to correct. Had to reset board to clear fault. Once board started to print file one drive , the machine would try to start, but the controller would reboot.Put 3rd party board in and all was fine. Asked vendor to replace $30 motherboard and they are passing to Amazon, who passed it to them in the first place.

This was my first CNC machine, but i have a lot of experience with machines in general. I'm happy with my purchase, but for $220 it's not perfect, but it has potential, and there's very little instructions. If you are new to CNC and Gcode, don't plan on plugging in and engraving something immediately. It includes the basic run software, but you have to have a drawing/editing program to create what you want to cut or engrave. personally i used Inkscape, and had to watch many many videos on how to use it, and many trial cuts to get it figured out and a week later, i'm cutting out some acrylic beautifully.Down to the nuts and bolts. While it does arrive pre-assembled, understand it's probably thrown together on a warped bench with little squareness, and the bolts holding the carriage was barely tightened. I played around trying to tram it and square it for 2 days before i gave up and took everything apart, measured everything and put it together the way it should be. What i discovered was the Z rail rods was incorrectly sized. The rods had a difference of .020" between them. One rod being .005" longer than the frame, and one rod .015" shorter than the frame. so when everything was tightened, it had a warped wave across the Z axis of nearly .050". Luckily i had a small lathe and could shave the .005" off one rod, and used brass shim stock to add .015" to the other. and in the end i was able to reduce the wave to less than .002" in 4 inches of the 12" of travel. the remaining 8" less than 0.0005" Another issue i discovered is there is a lot of runout in all of the axis's that need to be adjusted out by playing with the leadscrew backlash nuts. in the end i was able to get rid of all of the runout... less than .001" of play.. There is also an acrylic piece under the carriage which is for the limit switches.... and it can be modified to gain an extra 2" of travel on the Y axis if needed. I also upgraded the motor to 20,000RPM with a 15 amp power supply.... which works great, but in doing that, the candle program spindle speed is off by 20:1, and haven't figured out how to fix it yet. But the spindle speed is correct when it comes to the offline controller, which i haven't used yet.In the end. I'm happy with the engraver. I've been using it to cut precision parts which need to be nearly perfect. so i had to extra work before the machine could do that. But for basic engraving, i'm sure it would work great right out of the box even with it being slightly tilted.

The machine is great for basic hobby work. It is a 3018 Prover machine with and good solid frame and a 100W spindle. The machine has a good build quality and is value for money. Some other competitors are offering similar machines which are almost1.5 times the cost.If you want to upgrade to a larger frame and spindle (Router motor) I will not recommend this or any entry-level 3018 machines as an upgrade will cost you more than buying a larger machine.
