Good klipper config starting point for a Galileo made from the 1.5 LDO kit
Set run_current to RMS value dependent on the motor you have:
LDO-36STH20-0504AHG - 0.5A Peak ~ 0.35A RMS
LDO-36STH17-1004AHG - 0.5A Peak ~ 0.35A RMS
LDO-36STH20-1004AHG - 1A Peak or 0.7A RMS
Wantai EL36H20HM-1884A - 1A Peak ~ 0.7A RMS

[extruder]
rotation_distance: 35.65692
gear_ratio: 7.5:1
microsteps: 16
full_steps_per_rotation: 200

under
[tmc2209 extruder]
run_current: 0.7
hold_current: 0.1 <-- My klipper complains if I set to 0 as recommended by instructions on thingiverse

The issue does not name the documentation file; first locate the current Thingiverse reference and the section describing Galileo setup. Update the link to https://www.thingiverse.com/thing:4725897 and add the supplied Klipper starting configuration and motor-current details, including the hold_current note. Done means the documentation contains the newer design information and the configuration is readable and accurate.
