I have only had it about 6 weeks and it is a good design. There are a few things to be improved upon and I have designed and printed a few things to improve it. The real drawback of the design IMHO is the bed moving in the Y axis. There is always a little resonance with the bed movement and it effects the print quality at times. I am really interested to see how the MPCNC compares. I think it should yield more accurate prints if dialed in correctly. We shall see!
