I thought the same thing about automatically replacing a build plate before I saw your post, but now, it’s obvious that you don’t need a robotic to automatically replace a build plate. Really, for my idea, all you would need is a couple servo motors, a 3d printed arm, and some special GCODE to make the 3d printed arm come down after the plate has finished cooling, then the build plate moves back a little, and the arm rotates to the side causing the print to be swept off the build plate. Another way would be very similar to your swapmod, instead of replacing a build plate, it would just send the build plate all the way back, then either sweep everything backwards off the plate or push everything forwards off the plate. You could call it “The SweepMod” or “The PushMod”
