QUICK START GUIDE
For the LGX® Lite PRO
MACHINE CONFIGURATION
For the LGX PRO METAL to work on printers where current is
set with trimpots you need to adjust a couple of settings
regarding the extruder system.
VREF
This will differ depending on
your specific drivers. Aim for
about 550-650 mAh RMS.
Tuning the VREF, an example

E steps/mm
400 for 1.75 | 435 for 2.85
This is set by using the Settings.gcode
file or with the following gcode sent
in pronterface:
M92 E400 ; set esteps 1.75
M500 ; save esteps
Alternatively for LGX 2.85
M92 E435 ; set esteps 2.85
M500 ; save esteps
KLIPPER CONFIGURATION
Below we have listed the common Klipper parameters for
LGX PRO METAL
Rotation Distance for LGX 1.75
7.805
This is set in your [extruder] section
in your cfg in Klipper
rotation_distance: 7.805
#gear_ratio: #not used
run_current: 0.6
#hold_current: #not used
SLICER CONFIGURATION
When using the LGX PRO METAL 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.
Rotation Distance for LGX 2.85
7.356
This is set in your [extruder] section
in your cfg in Klipper
rotation_distance: 7.356
#gear_ratio: #not used
run_current: 0.6
#hold_current: #not used
