I already knew that Ender printers were not my printer of choice, despite their popularity, but today just confirmed it.
Last month I adopted an Ender Pro 3 printer a friend was about to toss off his balcony due to never being able to get it to work right. I replaced a few parts and got it up and running for about 2 weeks, only for it to then begin having multiple errors. I seriously spent all day today trying to get rid of errors and update firmware, only to end up with the blue screen of death and a dead printer. I am pretty sure I took off every screw on this thing, to check everything from the mainboard to the thermistor to the LCD screen. GGGRRRRRRRRR.
