PolyFlex is really on the lower end of what the Robox will print with. I have done it, but you have to have your settings exactly right and they will vary on your print head and extruder specifics, so you will need to run some trial and error.
As with all flex filament, you need to add a length of 2mm ID 3mm OD Bowden tube to the filament load port and run the filament through that. Then keep forcing the filament through the extruder. It takes a couple of tries when I do it.
You also need to make sure you have a gray extruder. If it is black you won't be able to load or print with flex filaments.
