To my knowledge, no one has attempted HDPE.

If the filament is coming out too thick is the temperature a) too high or b) too low.  I know I will need to dial in the temperature these pellets require blindly, as I don't know the specifications for the ABS pellets.  Any advise on how to do this properly?

Thanks,
John Barnes
