    Opeenbuilds MiniMill

    Posted by Frank Kaylor on Jan 9th 2019

    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!"
