MOUNTING HOLES
For the LGX lite V2 offers eight different mounting hole
locations for different uses. Side holes may be used for
peripherals such as accelerometers or toolhead boards
while the top hole is ideal for mounting a filament sensor.
The bottom mounting holes are commonly used for
mounting the LGX lite V2 to a toolhead.
The single side mounted hole is an addition we introduced
in this V2 of the extruder, in order to provide increased
flexibility when developing integrations.

driver trimpot and PSU ground.
The factory value is 1.25 volts.
Tuning the VREF
MACHINE CONFIGURATION
For the LGX lite V2 to work on printers where current is set
with trimpots you need to adjust a couple of settings
regarding the extruder system.
E steps/mm
562
This is set by using the Settings.gcode
file or with the following gcode sent
in pronterface:
M92 E562 ; set esteps
M500 ; save esteps
rotation_distance
5.7
This is set in your [extruder] section in your cfg in Klipper
rotation_distance: 5.7
#gear_ratio: #not used
run_current: 0.65
#hold_current: #not used
KLIPPER CONFIGURATION
Below we have listed the common Klipper parameters for
LGX lite V2
SLICER CONFIGURATION
When using the LGX lite V2 for the first time, verify the
retraction parameters in your slicer. For larger nozzles than
0.40 mm you may need to add length to this.
35 mm/s
0.6 mm length
If these settings still gives you stringing, we suggest you dry
your filament and calibrate your extrusion multiplier since
that is often the root cause of stringing when retraction has
these settings.
