3018 MX3 CNC Great Machine for the Entry Level DIY'er

I received this CNC as a gift from my son, Brian, and my wife, Donna. I have to admit the learning curve was more than I anticipated but I'm getting the hang of it and having a lot of fun. The FB group have been a great help and the Sain Smart customer service is fantastic. I have to admit, right out of the box (my son assembled it for me to save me some time) I was able to do a few simple projects. I'm the type that likes to explore all the features and there are several. I've already added the laser module, (thank you Brian). Great machine for the hobbyist with lots of additional capabilities to explore. [Open Box] Genmitsu 3018-MX3 CNC Router, Mach-3 Support Review

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.
