Backlash by Bondtech LGX-Lite

I'm making this post because maybe somebody will make the same mistake I did. I upgraded my LGX-Lite with some metal gears and ever since I did that the extruder couldn't seem to complete a first layer with small shapes anymore. After checking for obstructions, checking the extrusion and recalibrating the Pressure Advance I chose to disassemble the extruder due to noticing some backlash on the gears. Turns out that I lost one of the ballsprings of the LGX-Lite which push the selector part against the gears and hold the gears in place. Without both of the ballsprings the gear has soms radial movement when retracting and un-retracting (is this even a word?). So if you are experiencing any backlash on the gears, check those little bastards if they're still in place.
