3018-PRO-MAX 3 Axis Desktop DIY Mini Wood Router Kit PCB PVC Milling Engraver Engraving Carving Machine GRBL Control with Offline Controller

It was quite straightforward to assemble, kind of like legos but more metal. The quality of the CNC is quite good for what it's priced at and it cuts pretty well. I've been able to accurately cut PCBs even with the default setup.

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.

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.

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.

Esta relativamente bien, pero termine añadiendo mas cosas, como por ejemplo los limit switch y cosas pequeñas pero para grabar piezas esta super bien, si estudias una ingenieria y te piden proyectos quizá con esto puedas salir de apuros, pero es mejor tener una impresora 3D, es lo mismo pero mas divertido
