This routine consists of a series of tests. The progress and results of each step are
displayed on the LCD. In case errors are found, the selftest is interrupted and the reason for
the error is shown to guide users in troubleshooting.
The selftest is just a diagnostic tool, the printer will still attempt to print even after
the test fails. If you are absolutely certain that the affected part is correct, you may
continue with the print process.
The test consists of
●
Extruder and print fan
test
●
Heatbed
and
hotend
proper wiring
●
XYZ motors
proper wiring and functionality
●
XY axis
length
●
XY belts
tension
●
Loose belt pulley
test
● Filament sensor
test
6.3.4.1 Selftest error messages and resolution (kit only)
Front print fan/ Left hotend fan - Not spinning:
Check proper wiring of the print and the hotend fan cables. Ensure that both are
properly connected to the EINSY electronics and that they are not swapped.
Please check/ Not connected - Heater/ Thermistor:
Check the proper wiring of the hotend power cables and the thermistor cables.
Ensure that both are properly connected to the EINSY electronics and that they are
not swapped.
Bed/Heater - Wiring error:
Check that the heatbed and the hotend power cables are not swapped or that the
thermistor cables from both the hotend and the heatbed are not swapped in the
EINSY electronics.
Loose pulley - Pulley {XY}:
The belt pulley is loose and slips on the motor shaft. It is important to tighten the first
grub screw on the flat piece of the shaft, then continue with the second grub screw.
Axis length
- {XY}:
The printer measures the length of the axis by moving the print head from end to end
twice. If the measured value is different from the physical length, your print head
might be blocked from moving all the way. Check by hand if the print head moves
smoothly when the printer is powered off.
