First of all:
Pressing Pause during carving is one way to divide one long job into several smaller ones, as long as the USB-connection is kept intact. (No PC power save, nothing)
As far as your current 32hr indication, if you can share the design (or screenshot + carve specific details) we can see and advice if something could be more optimized.
If you have homing switches and did a homing sequence before setting your work zero, you can make subdivisions of your design (design allowing) and carve segments of the whole. With homing switches you can have a persistent work zero.
