I have a problem with my Ender V3 SE. While waiting to swap colors, I get the “Hot Bed cool error” with that horrible continuous beep. I researched online and thought it was the thermistor, so I replaced it with a new hot end, and it worked for about a week. Now the error has come back. I checked all of the connectors, and they are in place and don’t seem loose. I also checked the solder connections on the bed and they look solid. I also updated the firmware for the screen and the printer. I’m at a loss. Has anyone held this problem and fixed it? Please help!! I am trying to finish a Christmas Present. Thank You
Hi
I would try to reseat the main ribbon cable that goes on to the hotend. remove the locking screws then GENTLY remove the cable. Check for any bent pins then re assemble.
Also worth checking the connections on the daughter board, I have had one pin on the CR touch that was loose, there is a reason Creality put glue on these connectors. they are VERY fragile and can easily cause issues.
