I bought this machine in 2006 and two problems that with information from Cncmasters, I fixed these problems myself. I am still using this machine.

I would give the machine and the people selling this machine 10 stars if that was an option. I purchased the machine in February of 2011 and have been using it regularly since then. In the 10 years, the number of problems could be count on my fingers. I called for assistance maybe 3 or 4 times and each time I I got friendly and useful instructions to correct the problem. The only repair purchased was a $200 module that burned out because I located a cable such that it was crushed and shorted out. I love that machine.

Dear CNC Masters,
I had been spending a lot of time drawing one off my parts using CAD software and taking the drawings to local machine shops and paying a lot of money for each part. This greatly limited my experimentation for problem solving as I had to be very cost conscious for anything designed, because if it did not work, I was out a lot of money. This financial “stress” took the fun out of the designing and problem solving aspects of robotics. I was encouraged by my wife of all people to just buy a mill and do it all myself. Never having been within 3 feet of a mill in my life, I was intimidated by the concept, but I felt if I could teach myself to weld two soda cans together I could break enough end mill bits to learn how to use a mill. As a result of my learning from 30 lbs of aluminum stock from the remnant shop and going through a few cheap bits, the CNC Jr. has nearly paid for itself in under a year due to the cost savings of making parts myself. The learning process was fun and very straight forward thanks to the ease of use and the great phone support from CNC Masters and Mecsoft. My wife now refers to my CNC Jr. as my three dimensional printer for metal. She asked me one day “what is so exciting about this machine?”, I told her it is a metal printer, I draw a part on the PC, put metal in the machine and the part I drew comes out. I also told her “this is so cool, I wish I was 20 years younger so I could play with this that much longer!” Thank you for a great easy to use machine.
Best Regards,

“The CNC Jr. Mill is purchased for general machinery by members of the Astronomical Instrumentation Group here at the Jet Propulsion Laboratory. As the name of our group implies, we design and fabricate sensitive millimeter wave instruments for astrophysical studies. The CNC Jr mill will provides a quick and cost effective way for us to prototype great variety of mechanical parts needed by our experiments. Thanks to its fabricating capability, the facility really adds lots of fun to the work we’re doing here in the lab.”
