Great Value
I absolutely love it. It is a little more intricate that I had thought, but easy enough to assemble and get running. I am not new to CNC milling/routing so my expectations were not too high based on the price, however, I was pleasantly surprised with this little machine. For its size and price it seems to have a lot of potential. I have opted to not use a "traditional" router, but rather the "popular" 500 Watt 12,000RPM spindle that can be purchased almost anywhere. This did require me to make up a custom adapter plate, or interface to allow the bolting on of the spindle clamp to the Z axis, with no modification to the original MiniMill itself. I decided on this spindle mainly due to my previous experiences with it and its much quieter noise profile vis-a-vis a "router". Looking forward to putting it through some work, after which time, I will provide a more in depth analysis of my experience, but so far I feel it is 100%. Thank you OB for your great products which are only overshadowed by your superb customer service.

Opeenbuilds MiniMill
I received the MiniMill kit just a few days ago and am in the process of completing the build. All of the mechanical parts are complete and I'm now working on the electronics. The kit was very well engineered and I am sure it will be a great companion to my large OPENBUILDS CNC Router. The assembly video was very helpful...I've just about memorized the script..."Looks good...On to the next step!"
