This refers to a problem with the PT100 B sensor, which is the sensor that
measures the temperature of the nozzle. It means that the sensor registers
incorrect values and due to safety reasons it will prevent the nozzle from
heating up. The most likely reason for this is connection problem, which
could either happen due to a bad connection at the main board or damage
of the sensor itself.
This error refers to a problem with the sensor of the heated bed. It means
that the sensor registers incorrect values and due to safety reasons it will
prevent the heated bed from heating up. The most likely reason for this is
connection problem, which could happen due to a bad connection on the
heated bed or main board, or damage of the sensor itself.
The heater error can appear when the sensor doesn't register a steady
(increase in) temperature. This could mean that the heater cartridge is not
connected properly and to prevent overheating of the nozzle it will therefore
turn the heater cartridge off.
If you get one of these errors it means that there is a problem with the Z
limit switch. It either tells you that the Z limit switch can't be pressed or that
something is preventing the lever of the switch from switching back.
This error occurs when either the X or Y limit switch is not activated while
the print head is homing.
