Morgan baseplate is approximately 40x50cm in size.
The arms however can reach much further. The arm segments are 150mm long and can reach 280mm from the tower without trouble.
Morgan Pro comes with a 380×220 semicircular bed. It capitalizes on the reach to make the machine essentially print “outside the box”
The elbows stay within the frame by design, but this can be changed. Nothing prevents you from making the arms longer.
