I’ve been 3D Printing for about 5 years or so. My level of experience is more than moderate, less than expert. Repaired lots of printers, upgraded them to actually work, and run a Maker’s Print Farm at Lowell Makes, MA. Currently we have four FFF Prusa’s, an X-MAX, 2 functioning Ender 3, Ender 3 turned into a Prusa mechanical system, and two Ender5 Pluses. Active users, at any given time of year 10-30.

The A1 Combo is my personal printer set up to display capabilities. Very pleased so far.
