Bought this printer because we wanted a cheap side project that can also print some huge prints. Issue is after a couple prints it started to do this. I replaced the nozzle and bowden tube but suspect the extruder is slipping big time. Could this be extruder slip? The perfectly lined up spirals in the last photo make me unsure.
Side question, if extruder issue is the case should I do a BMG direct drive swap or would that put too much weight on the gantry?
