Printing Notes

PLA Basic comes on a thinner standard spool. It feeds well from the external spool holder, but for the AMS we suggest moving it onto an AMS-compatible reusable spool first for consistent feeding.

The X1C has no chamber heater, but bed heat builds up with the door shut. Bambu Lab recommends opening the front door and removing the top glass when the bed runs above the filament's softening point, so do this for long PLA prints at 55 – 60 °C.

With the AMS you can print a PETG support interface. PLA and PETG do not bond to each other, so supports peel away cleanly. Use it for the interface layers only, since every filament change adds purge waste.

Like all PLA, PLA Basic has a heat deflection temperature of 53 °C. Keep finished parts out of hot cars and direct summer sun.

Slicer: Bambu Studio. Start from the Generic PLA filament preset and set the temperatures above. Every figure assumes dry filament, so dry at 50 °C for 5 h before a long print.

Troubleshooting

Stringing between parts: Check the filament is dry, then drop the nozzle to 205 °C. Only raise retraction once those two are ruled out.

Corners lifting on large flat parts: Wash the plate with warm water and dish soap to remove fingerprints, then raise the bed to 60 °C and slow the first layer to 20 mm/s.

Soft or drooping overhangs: Confirm the part cooling fan is at 100 % and lower the nozzle to 205 °C.
