position and lift the print head away from the print. In case of a very short power failure, the
printer will attempt to continue printing immediately without waiting for user interaction. The
printer can recover from consecutive power outages or even very short power outages (<50
ms).
When the power comes back, the printer will give you an option to continue the print. Keep in
mind that during long periods without power, the bed will cool down and the print can detach
itself from the sheet plate. Power panic doesn't work if you interrupt the print with the on/off
power switch.
7.2.13 Crash detection
The Trinamic drivers on the EINSY board can detect skipped steps and layer shifting. It
works only in the
normal mode (not in the Stealth mode)
. The thresholds for crash
detection are set for higher speeds because layer shifting happens most of the time when
the extruder moves fast between objects and hits a piece of curled up print. Make sure that
your
belt and pulley are tightened
. Would any of them be loosened, it may cause the belt
to jump over the pulley or the pulley to spin around the motor shaft and the printer will not be
able to detect it. Check out chapter
14.4 Loose X- and/or Y-axis belts
If you want to test crash detection, just pinch the smooth rods and let the extruder hit your
hand. Crash detection doesn’t work if you push the extruder in the direction of its movement.
That’s not a real-world scenario and normally never happens during print.
7.2.14 Temperatures
By default, the printer shows the heatbed and hotend temperatures on the LCD screen.
If you also want to check the ambient temperature, you can do so in the
LCD Menu -
Support –Temperatures menu
. The same menu is available during the print.
The printer uses the ambient temperature reading to differentiate between MINTEMP
caused by low ambient temperature (below 10°C) and an actual problem with either the
thermistor or the heating element.
7.2.15 Voltages
If you encounter really long preheat times, or the printer is behaving in a weird way, you can
check the PSU output voltage in the
LCD Menu - Support - Voltages
menu. You should see
the PWR (power supply) value of around 24V (+- 0.5V). If you see a drastically different
value, check the connection between the PSU and EINSY board and contact our support if
the problem persists. The BED (heatbed) voltage should be almost the same as PWR
voltage. If you see value around 0V, check the 15A fuse on the bottom of the EINSY board.
The IR value represents the actual voltage measured on the pin of the filament sensor. With
the filament inserted in the extruder, the value will be between 0.3-0.5 V. Without filament,
the value should be between 4.2-4.6 V.
