Thanks for chiming in. Can you provide some info for us?:
What temperatures have you tried printing at?
Do you have a fan setup? Are you using a shroud or deflector?
When does the jamming happen? First layer? Middle of a print?
What are your retraction settings at? (Speed and length of retraction)
Do you have a pair of calipers around to measure the filament diameter in a couple different places across the windings of your spool?
Thanks,
Mike
