Yes of course,my fault.I have done different settings in basic and expert,no improvement.First i thought it was from vibrations,while the desk where the printer was got a bit loose,so i moved it to a more solid surface,improvement was maybe minimal.I think it may be something when the extruder/hotend assembly has circular movements,also i cant print overhangs as i printed before,not even close,every is a fail,also the prints quality in general is much worse,sometimes i get blobs,sometimes i get bad quality outer walls,sometimes i get weak prints,no matter of infill,layers seem to stick well, but i feel that the prints are weak,not strong as before under same settings,tried different temps and filaments,always the same.I dont know,extrusion seems well,the problems begin when it has some of circular movements,on some stuff/prints where the movements are more straight they really seem really ok,but when the printing goes around and around problems start happening,that is what i noticed,also extruder is clean, new nozzles,heatblocks are fixed well,i considered to replace thermocouple and heater cartridge,it may be temperature inconsistency also,i dont really know
