I have just finished building a printer and it is working fine except for one issue. When I plug in the thermistor for the heatbed I get this error message scrolling continuously; Error: : Extruder switched off. MINTEMP triggered ! Error:Printer halted. kill() called !! Error: : Extruder switched off. MINTEMP triggered ! Error:Printer halted. kill() called !! The thermistor is the same type as used in the hotend, both are 100K I tried swapping the hotend for the heatbed and also the thermistors too, and I still get the same error message, so I guess that the settings in the firmware may be at fault?? It seems strange that the error message refers to the extruder. Any help would be appreciated. PS: I have tried a few Printrboards (revD) and they all do the same with my setup. https://reprap.org/forum/read.php?146,164171,164171#msg-164171 Thu, 08 Oct 2026 21:48:36 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?146,164171,164239#msg-164239 https://reprap.org/forum/read.php?146,164171,164239#msg-164239 The reason I feel that the problem must be with the settings is because I can take the thermistor that is being used for the hotend that is working OK and plug it into the heatbed thermistor socket, that is when I get the error message. If I plug in the thermistor for the heatbed I still get the same message. Both thermistors are the same type, 100K
I have tried two boards and got the same result from both of them.]]> regpye Firmware - mainstream and related support Sun, 04 Nov 2012 10:02:41 -0500 https://reprap.org/forum/read.php?146,164171,164209#msg-164209 https://reprap.org/forum/read.php?146,164171,164209#msg-164209
To help others wishing to help you, tell us what firmware are you using? Using what program do you see the error message? What are your electronics?

Check your wiring first.]]> spaceman Firmware - mainstream and related support Sun, 04 Nov 2012 07:05:33 -0500 https://reprap.org/forum/read.php?146,164171,164171#msg-164171 https://reprap.org/forum/read.php?146,164171,164171#msg-164171 When I plug in the thermistor for the heatbed I get this error message scrolling continuously;
