The Flashforge Finder is a great entry level machine. Flashforge has Polar Cloud enabled the most recent Finders but you'll need to read below to see if yours is compatible.

The easiest way to tell is to see which type of power supply your Finder uses. If it uses the old style, internal power supply (left), it is not compatible regardless of the firmware you upload on it.

If it has the external power supply (right) you just need to make sure you're running a firmware after 2017.11.11. This can be found via the printer's LCD screen, by going to TOOLS and then to ABOUT and looking at the firmware loaded.

Once you're running the Polar Cloud compatible firmware, the steps to add to the cloud are the same as for the Inventor II S. More info here!
