Pict. 24 - Distance of the front calibration point from the axis start.
Pressing the button will get you to the 2nd screen. This screen will identify how far you are
from the perfect perpendicularity. It is measuring the skew of your X/Y axis.
Up to 0.25
° = Severe skew compensating for offset of 1.1 mm on 250 mm length
Up to 0.12° = Slight skew compensating for offset of 0.5 mm on 250 mm length
Under 0.12° = No need to compensate, X/Y axes are perpendicular. Congratulations!
8.6 Linear Advance
Linear advance is a technology that predicts the pressure build-up in the extruder when
printing at higher speeds. Firmware of the printer uses that prediction to decrease the
amount of filament extruded just before stopping and decelerating, which prevents blobs or
artifacts at the sharp corners.
If you are using PrusaSlicer, Linear Advance is already set
up in the filament profiles.
MK3S+ features Linear Advance 1.5 starting with firmware
3.9.0. It is recommended to re-slice older G-codes.
If you are using different slicers from PrusaSlicer, or you just want to tweak and play
around with different values, you can manually change the settings in g-code script.
However, i
f you do not understand the concept of G-codes yet, or never played
with editing it, stop reading here and skip to another chapter.
The recommended K values (the parameter affecting how much Linear Advance
affects the print) for each material and more instructions can be found
.
8.7 Extruder info
Extruder info can be found in
LCD Menu - Support - Extruder info.
It provides debug
information about the function of the fans. Exact RPM may vary, but any major change, or a
zero value, is an indication of a problem.
● Nozzle FAN RPM
● Print FAN RPM
8.8 Sensor info
This menu can be found in
LCD Menu - Support - Sensor info
. It provides information
about:
PINDA
- [0, 1] Induction sensor placed on the extruder body. If the sensor detects a metal
object (such as the steel sheet) it shows a value of 1 (triggered).
