Hi, I recently purchased my Ultimaker 3 Extended after selling my old Makerbot Replicator Mini due to extruder problem. I bought 9 different 1.75mm PLA spools to have many colors. Now that it is gone, I still have the spools. I tried to print a test object with the filament , but there was not enough material coming out for it to print successfully. I tried to turn up the material speed (I think that is what its called) but it just made it work. Could anyone give me some suggestions on good settings to start with? Thanks
