6.3.4.1 Selftest error messages and resolution (kit only)
Heater/Thermistor Not connected:
Check proper wiring of hot end power cables and thermistor cables. Ensure that both
are properly connected to the Rambo electronics, and that they are not swapped.
Bed/Heater Wiring error:
Check that heatbed and hotend power cables are not swapped or thermistor cables
from both hotend and heatbed are not swapped in the Rambo electronics.
Endstops Wiring error {XYZ}:
Check the proper cabling of endstops. Routine indicates axis on which endstop
reported malfunction or is not properly responding. Check the proper connection in
the Rambo electronics.
Motor {XYZ} Endstop {XYZ}:
Check that motor and endstop on indicated axis are properly connected to the
Rambo electronics and not swapped with motor or endstop of different axis. Axis
causing the problems is indicated on the LCD panel.
Endstop not hit Motor {XZY}:
Check mechanical settings that endstop can be reached when axis is in minimal
position.
6.3.5 Calibrate XYZ
(kit only)
The Original Prusa i3 MK2 comes with a full mesh bed leveling feature, however
for this to work we need to first calibrate the distance between tip of the nozzle
and P.I.N.D.A (
P
rusa
IND
uction
A
utoleveling) probe.
The process is fairly straightforward, so let’s get to it. We also suggest to check
out our Guide for New User first at
www.prusa3d.com/buildvideomk2
with calibration tips.
The purpose of the X/Y/Z calibration routine is to measure the skew of the X/Y/Z axes and to
find the position of the 9 calibration points on the print bed for the proper bed leveling. You
can run the
XYZ calibration
from
Calibration
menu on LCD panel. This should not be
necessary on the assembled printers as those are factory calibrated.
Be sure you’re using
the firmware version 3.0.6 or the latest one!
Initiating this routine performs a series of measurements in three rounds: In the first round, 4
sensor points on the print bed are searched for carefully as to not touch the print bed by the
nozzle. In the second round, all 9 sensor points are found. In the last round the height above
the 9 sensor points is measured and stored into a nonvolatile memory for reference, this
finished the Z axis calibration.
