From building a professional electrical cabinet to configuring the quad gantry leveling, this video covers the circuits required to not only power this massive machine but also create a reliable printing experience. When dealing with a 4’ x 4’ (1220 mm x 1220 mm) build area, the levelness of the build plate is critical for successful printing. Dr. D-Flo throws the kitchen sink at this bed leveling problem by using manual, mesh, and gantry leveling. After compensation, Dr. D-Flo was able to achieve a levelness within 0.250 mm, which is more than workable when printing with at least a 1 mm layer height. Because the bed leveling went so smoothly, Dr. D-Flo was able to fire up a test print. While many settings need to be tweaked, you can see the potential of the large format printer.
