Hello all: The new guy here. New to the forum and to printing. I have one of the many Prusa clones out on the mkt and it was printing really well until the power supply started sparking. I bought a 30A replacement and installed it iaw instructions from the mfg of the printer. About three days later the hot end died and I got a replacement and installed it. It only heated to 90deg and then started falling 20 deg. Now before I go and buy a new anything I am wondering if I may have not adjusted the power out put to the correct vdc. What is the optimum power setting for this printer? Where does it work best? I may have missed something and may not be putting out the needed out put in order for everything to work correctly. If you can enlighten me I would be very grateful.
