CNC Router 3018-MX#

I was really impressed with the quality of this kit. It was very well packaged and had zero damage upon opening package. All the parts were there. I was very impressed with the quality of all the parts. Even the many Socket Head Cap-screws appeared to be polished. Everything went together smoothly. (Buy I do recommend watching the videos and studying the manual before starting. One other thing: the manual as supplied is very small so I strongly recommend pulling up the pdf manual so you can zoom in on details.) I can’t emphasize enough how great this kit is. All the parts are such high quality! Just take your time and refer frequently to the excellent instruction. The recommended software: Drufel CNS (free) and the expensive Mach3 CNC both work well after a pretty steep learning curve. More detailed instructions on the software would have been helpful. I’m going to stop here (for now) while I practice using the software and making a few parts. I will return with an addition or an additional review in a few weeks.

Great machine to learn how to use and get into cnc machining

Absolutely sturdy and well designed machine for those looking to start in cnc machining. Im going to play with this machine and possibly modify and upgrade it or buy another to add to my arsenal of machines in the shop. Worth the money.

Great product, well packaged and fun to build

This kit is fantastic, the packaging of the parts is excellent. I think what stands out for this kit though is the standard of the instruction booklet. Great visual guide to building the machine. It took me around 4 hours to have this built at a nice leisurely pace. The customer service of Sain Smart has been great, quickly responding to my questions on setting the machine up.
