This mill comes with very little instruction aside from assembly in fact the instructions I received were for a model with a laser... Even though they don't come with a laser... or sell one that I can find which will fit this machine for that matter, And finding a laser that would fit the fixture isn't easy. I had to use a file and modify it just to get mine to fit. I'm currently in the process of redesigning the entire z axis so that i can quick connect/disconnect the laser I purchased and the spindle motor. They say this thing can do aluminum, i wouldn't recommend trying that. Not with the spindle that comes with the machine anyway. The thing I hate the most though is the GRBL board is completely exposed with no protective covering whatsoever and was not compatible with my laser. I've already replaced it because I accidentally broke it while troubleshooting something due to the lack of any protective coverings, and it lacked a few features I wanted anyway. The enclosure they sell with it is also mediocre in quality, one of the sides is connected via cheap magnets and they wouldn't stick without significant amounts of superglue. Unfortunately this specific machine doesn't have much in the way of YouTube help either, most of the stuff you will find are related to other brands. You can still learn, but there will be a steep curve. If you wanna throw yourself in the deep in and struggle, sure, go for it. But I definitely don't recommend this for anyone who has no experience with this type of stuff, and I'd really suggest you buy/install limit switches ASAP so you do not accidentally damage your machines stepper motors. Everything on this this is cheap, and can be upgraded. So if you just need to start somewhere, I guess this works but honestly just save up your money and buy something a little nicer. Cuz you're definitely gonna wanna upgrade the spindle motor at minimum.This is basically a 3018 CNC mill with a VEVOR sticker on it. Unfortunately, there are several serious issues with it:1) No support: When contacting the support email address in the manual, this is the response I received...Dear Customer,This is Amelia from Vevor after-sales support team. Thanks for purchasing our products.We see that your question comes from the Amazon platform, but we are the official website service team, and we are not authorized to deal with the issues from Amazon, eBay, or Walmart.So, please contact the corresponding after-sales support team.Thank you for your understanding and hope your issue will be solved as soon as possible.Sincerely,Amelia...unfortunately, they did not provide a contact info of a "corresponding after-sales support team". And no wonder, because no such team exists.2) Shoddy materials:- The enclosure is touted as clear Acrylic. What it actually is is hazy Polycarbonate. might as well cover the machine with a bucket because you can't see inside. Furthermore, the panels were cut poorly and the mounting holes were wildly off. It was completely useless.- The corner brackets of the enclosure were so brittle that even the slightest tightening of the mounting screws would break them.- The preassembled spindle enclosure is plastic and results in so much play that even the simplest engraving on soft woods comes out terrible. To be fair, this is a known issue on all 3018 machines, but this particular flavor of it is the worst I've ever seen.3) Incomplete control board:If you want to add something like a z-probe - good luck, because it turns out that they didn't bother to add the Dupont terminal block pin header to the PCB board where the A5 connection should be. Hope you enjoy soldering small electronic components into tiny holes.In conclusion, 3018 machines are a good way for a beginner to get into CNC milling, however absolutely DO NOT buy one from this vendor!!Do not go in execting a 3D printer or cutting steel.Ya know, if you relise this machine is cheaper then a vinyl cutter and with a few accessories can do way way more, it is well past worth it. Yeah you have to learn a bit, but, come on, the thing is the cheapest CNC of its size. look up on youtube improvments you can make to it, I am already cutting; aluminum, plastic, vinyl, wood, only one month in. It supports a laser too. Be realistic, do not look at the machines at college or work and compare this to them. Also it was super simple to assemble, the learning curve comes into play when you set out to make GCode for it as any free software has a steep learning curve, easy software is expensive. It comes with software to run it, but unlike 3d printer software that takes 3D models directly, CNC machine software needs CAD/CAM software to make a file to then use on the CNC software. also my machines steppers are slop free, no wiggle in or out this saves from "backlash error" and look for that before you assemble, the shafts on mine do not jiggle only rotation like expected.Not worth itUnclear assembly instructions, very unclear directions as to start up, and usage.I've got some experience assembling 3D printers so the picture instructions were sufficient for me. After assembly I find that I can control the X, Y, and Z axis via the controller but when I try to turn on the spindle everything looses power and then comes back on again. I used my own bench power supply (24V 5A) and everything seems to work okay. So seems to be a defective power supply. I contacted the seller and was able to arrange for a replacement power supply. With a working power supply everything works as it should.
