3. SYSTEM ERRORS AND THEIR REMOVAL
E201 – problems with reading the indications of the printing module force sensor. The force value is outside the measuring
range.
Confirm that:
• hotends have been installed correctly,
• the printing module has not been mechanically damaged,
• after Z axis referencing (Rise Heatbed option in MENU), there is no contact between any element of the printing module
and the heatbed. If there is a contact, adjust the position of the Z axis endstop (chapter III, point 3.1),
• no considerable force is applied to the hotend by other printer's elements, e.g. the systems feeding the material to the
hotend.
INFORMATION: the correct force readout value should be within the range of -15500 – 15500 units. The value can be read by
choosing the Diagnostic info option in Advanced menu. The force readout value is under the Force Sensor item.
E202 – wrong position of the Z axis endstop
Wrong position of the vertical axis endstop. The maximum value of the distance between the hotend and the heatbed has
been reached. After Z axis referencing (Rise Heatbed option in MENU), the distance in any place above the heatbed should not
exceed 1.5 mm. If this error occurs:
• if the distance is outside the range of 0.8 mm - 1.5 mm, adjust the position of the Z axis endstop (chapter III, point 3.1),
• if the distance is within the range of 0.8 mm - 1.5 mm – check whether the force sensor reacts to pressure. To do this,
check whether the Force Sensor value changes when a force is applied to the printing nozzle tip (the value can be read by
choosing Diagnostic info option in Advanced menu). If the value does not change considerably after application of the
force, contact the technical assistance department.
ATTENTION: the hotends and other elements inside the printer chamber may be hot and cause burn hazard. Be
especially careful and use a metal object such as tweezers to apply pressure. Under no circumstances should you
touch the printer parts with bare hands.
E203/def/Temperature Sensor Fail – temperature sensor error. Problem with measuring the temperature of one or more
heating devices.
Turn off the main power supply of the printer immediately and make sure that:
• hotends have been installed correctly,
• the printing module or other printer's elements have not been mechanically damaged,
• the conduits inside the printer and under the top service cover have not been damaged.
If the hotends have been installed correctly and/or one of the above defects has occurred, contact the technical assistance
department.
E204 – problem with the minimum position of the Z axis endstop
Wrong position of the vertical axis endstop. The minimum value of the distance between the hotend and the heatbed has been
reached. After Z axis referencing (Rise Heatbed option in Menu), the distance in any place above the heatbed should be at least
0.8 mm. In particular, there should be no contact between the printing nozzle tip and the heatbed. If the distance is incorrect,
adjust the position of the Z axis endstop (chapter III, point 3.1).
E205 – measurement accuracy is outside the tolerance
The printer measures the tool height correction using a force sensor. The measurement is repeated in order to check
repeatability and accuracy of measurement. If the accuracy is outside the tolerance range (0.02 mm), error E205 is signalled.
Confirm that:
• the hotend and/or the heatbed are free from dirt and particles of material other than thermoplastic filament,
• hotends have been installed correctly,
• the printing module has not been mechanically damaged,
• after Z axis referencing (Rise Heatbed in MENU), there is no contact between any element of the printing module and the
heatbed. If there is a contact, adjust the position of the Z axis endstop (chapter III, point 3.1),
• no considerable force is applied to the hotend by other printer's elements, e.g. the bowden tubes.
