I have a robo r1 + printer and recently replaced the extruder with an e3d V6. Before I was dealing with too many jammed filiment issues. The first couple of layers prints just fine, but afterwards the prints gets all messed up. I've included pictures of the prints. So far I've tried to lower the speed, decrease the extruder temp to 200 c, and replace the filament. No improvement. Hoping the community can give me some ideas on the what else to try. The last picture is a print from before I replaced the extruder. Thank you so much and look forward to listening to the communities ideas!
