So I fixed my cartridge not recognized issue, though now I have another problem where resin isn’t being dispensed from the cartridge.
I squeezed the valve and it seemed to open. One thing that happened earlier is I tipped the cartridge to look underneath and resin spilled out of the cap which I left pushed open. Could this have affected anything?
Thanks guys. I think the inside slit of the valve was stuck as only the outside slit opened up. I was about to ease it open with a pointy stick though it suddenly started working in the printer. Maybe the 50 or so attempts finally loosened it
