CNCTOPBAOS CNC 3018-PRO-MAX 3 Axis Desktop DIY Mini Wood Router Kit PCB PVC Milling Engraver Engraving Carving Machine GRBL Control with offline controller Hand Control (w/Offline Controller)

I bought this machine for the sole purpose of cutting a particular shape out of anodized 1/32 thick aluminum sheets. When the machine arrived, one of the stepper motors was defective and did not have enough torque to move the lead screw. After contacting support, they were able to assist and I was up and running! If you are cutting metals, the v bits that come with the machine are not going to get you very far. After some research, I got some up cut endmills that cut the aluminum, but broke very quickly. After more research into feeds and speeds and adding some oil to the surface of the aluminum, I am getting successful cuts without breaking bits! A few things to help get started with the machine! You are probably going to break a lot of bits starting out, so be prepared to budget for this and maybe start with some cheaper endmills before dropping a lot of money on the high end stuff. You will need a spoil board under your project if you are cutting all the way through. You can 3d print something to work if you have access to a 3d printer, or you can use wood. Of using wood, make sure it is flat, or mill it flat after installing. Go slow. The spindle in this machine is mounted with an injection molded plastic part that has a single screw to tighten the spindle into it. This piece will flex with enough resistance and ruin your project if your feeds and speeds are not right. Be patient. This machine is not an industrial machine at all, but rather an intro into the world of CNC milling. There are going to be ways to upgrade it with a better spindle, an offline controller, etc, but try using the machine as is before dumping extra money into upgrades that may not net the results you need.

Keeping in mind the size and power limit the work you can do, this is a remarkably solid little unit. More for carving/engraving and some "Light" mill work & routing. I found the assembly easy and had it running within a couple of hours. The software is crap (but I knew that going in) but there is plenty of good, free software out there that make getting started straight forward. More advanced Mill/routing work will have a steeper learning curve but that's in the CAD/CAM software, not the unit. The unit I got didn't come with a Z probe or limit switches (I knew that when I ordered) but the driver board is set up to accept them. I recommend adding the, I did. The newer Woodpecker 3.4 control board is not set up to receive an E-stop switch which it should (the older Cronos Maker board was so equiped). I'll wire mine into the DC Power line. A fair amount of upgrades are available but the base unit, as delivered, is solid. Plenty of You Tube tutorials for this unit are out there, Which I found to be of great help. All in all, Very satisfied.

Perfect size for small projects. Bits that come with it are junk, so save yourself the headache and plan on buying better bits. Overall, it's a very basic machine with barely any safety features. Power isn't impressive, but it works with very shallow cuts. You get what you pay for, but so far this has been a pretty solid entry-level machine.

Va bien para arrancar, si querés algo que corte en profundidad, que no se vaya a trabar porque querés trabajos más grandes, entonces no es esta la máquina para vos. Si para tallado, corte de piezas no tan anchas y trabajos lentos, con paciencia

Machine arrived undamaged. Came with a paper Part A: Assembly Instructions and Part B: User Manual, and remaining manuals, pictures and videos, controlling software, etc. on a thumbdrive. However, all the files on the thumbdrive were corrupted/un-usable. The was NO contact information to reach the Seller initially, but Amazon support directed me to a link to send the Seller a message. Still, the link says to wait several days for a response from the Seller. Not happy with the situation. Machine is un-useable as is - great paperweight at the moment.

No matter what I do, I can't get the Y-axis table to move without binding. I've adjusted the sliders, slide rods and drive screw repeatedly. I tried lubing the drive screw and rods. The table is square to the frame and I tried swapping out the motor with the X-axis motor but get the same results. This is not the first time I've assembled something like this and I build stuff for a living so it's not lack of skill causing the issue. I have no idea how well the machine works because I haven't gotten that far yet. The X-axis and Z-axis components move fine and the spindle fires up on command so if I can get the Y-axis problem resolved, it should work fine. Amazon suggests I return the one I have for a replacement but then I'd have to disassemble the whole thing and pack it back up. I'd rather get help figuring out how to make it work or get replacement parts but I can't find any tech support contact information. Based on other reviews, this seems like an uncommon issue but it is still an issue.

Es una muy buena maquina, tiene potencia suficiente para grabar y cortar acrilico. La compre más específicamente para grabar pcb los cuales aun no pruebo pero creo que no dará problemas. No es difícil de ensamblar pero si laborioso y algo tardado. Sugiero engrasar los ejes para que los baleros se desplacen más suave ya que se sienten un poco duros. Igual hay que informarse bien antes de usarla, ya que es un poco enredado generar los gcode y sin un buen conocimiento se pueden romper las brocas.

Muy buena máquina apenas me estoy introducciendo en el mundo cnc y para aprender es perfecta

Es muy buena pero tiene algunos aspectos a considerar. 1. El eje "z" al ser de plástico se llega a doblar en algunas ocasiones (al momento de grabar aluminio) o cortar con velocidades altas, esto no pasa al trabajar materiales blandos a una velocidad moderada. 2. La bancada (cama) tiene una ligera inclinación de .15 mm hacia la esquina inferior izquierda, esto casi no afecta en los cortes pero se ve reflejado en grabados ya que el grabado queda con diferentes profundidades (muy poco pero visible). 3. Al conectar la máquina al software "Grbl Candle" las medidas no son precisas, por ejemplo: al hacer una línea de 100 mm la máquina hace una de 91-93 mm y hay que calibrarla, cosa que no sucede desde el control offline ya que al enviar desde el control offline la precisión es absoluta "sin considerar la inclinación de la bancada" (personalmente solo uso el control offline). 4. No tiene límites de carrera y al sobrepasar los límites la máquina se forza y podría romperse o provocar una lesión a la máquina. 5. Al adquirí la máquina no viene lubricada perfectamente y hace un chillido lo cual se soluciona con lubricante el cual hay que poner independiente lo cual no es una molestia pero vendría bien que ya llegará lubricada. 6. La máquina no se aprovecha al máximo ya que la bancada está muy justa y nunca he aprovechado realmente los 30 cm × 18 cm ya que los soportes que sujetan el material a trabajar ocupan de 1 a 3 cm por lado dependiendo la posición de los mismos el material más grande con el que he podido trabajar es de 26 × 12 cm para sujetarlo correctamente. 7. Los sujetadores para la bancada no tiene la cabeza en v- slot por qué son tornillos comunes y no sé sujetan solos y para apretarlos hay que agarrarlos con una mano y con la otra apretar la tuerca de mariposa, esto no es muy cómodo pero los sujetadores con cabeza v- slot son costosos y al ser una máquina barata no podemos pedir mucho.

Trabaja de maravilla a la hora de diseñar tarjetas de PCB, si acaso la única recomendación es que el soporte del eje Z tenga el tope adecuado para la tuerca anti retroceso para evitar movimientos que alteren el movimiento del ya mencionado.

El ensamble fue muy fácil, funcionó muy bien al inicio pero al querer hacer trabajos mas delicados para PCB's el eje z generaba mucha vibracion y no hubo forma de arreglarlo, tal vez lo solucione comprando alguna actualización pero esta vez de algún material mas resistente y con unas guias de mejor calidad.
