hello everyone! over the last couple days my replicator 2 has been acting oddly. it started off with a clicking sound accompanied by a irregular flow of melted plastic. I thought the filament was merely slipping so i took the assembly apart, cleaned the feed gear, tweaked the tension spring, and adjusted the operating temperature a bit but the problem persisted. Currently the problem has changed. It no longer clicks and stutters, but now the extruded stream of plastic is very thin and barely adheres to the build platform. I am reasonably sure that the nozzle is merely clogged so i ordered a few new ones but i am now afraid that the feeding gear or (god forbid) the stepper motor is going bad and needs to be replaced. Has anyone dealt with something like this before? If so, any advice would be appreciated.
