After having the printer for 2 months, here is my experience. The printer took about 1 month to arrive and for the most part, everything was there. I had an issue with one of the linear bearings (difficult to slide) that was replace after a conversation with John. It took me about 20 hours to complete the build. I've made a few modifications/additions: - Added a Raspberry Pi 2 Model B runningby jh1 - Delta Machines
