BUT it did flawlessly work if the CARD was actually inserted. It WOULD then show NO CARD but as it sat, UN-TOUCHED it would beep periodically and flash the LCD etc. With the thingiverse fix installed, if I pulled the card while displaying gcode file names, it would show a line across the LCD of some “dot like characters” they would disappear and then show BACK (I think it thought the card was still inserted but could not read the files”, and a “reverse” arrow on the LCD for maybe a minute THEN finally switch to the INFO screen. Which DID fix the NO CARD issue immediately BUT with some NEW weird symptoms. SCARY!!!!įirst Fix Attempt: I applied the “thingiverse” fix Also I found the card was VERY touchy if you bumped it, it would LOSE apparent contact and go to NO CARD.
If I pushed the card back in, LCD would go back to NO CARD. Symptoms: As I would insert the card it would show NO CARD unless I pulled the card back about 2mm. Issue: SD card reader periodically not reading. Prusa Mk3s purchased in December of 2019.
