• The default 0.8 mm retraction is enough at speed. Increase it in 0.2 mm steps only if stringing continues after drying the filament.

Printing Notes

High Speed PLA is a toughened PLA made to melt and extrude evenly at speed, so it suits Bambu Studio's faster process presets better than standard PLA.

Faster printing needs more heat. Run nearer 210 °C at moderate speeds and nearer 220 °C at the top of the speed range, but do not go past 220 °C.

Speed is also capped by the max volumetric speed in the filament preset. If fast prints show gaps or rough walls, the hotend has run out of flow, so lower the speed.

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.

Slicer: Bambu Studio. Start from the Generic PLA filament preset and set the temperatures above. Every figure assumes dry filament, so dry at 40 – 45 °C for 4 – 6 h before a long print.

Troubleshooting

Gaps in walls or thin top layers at speed: Flow limit reached. Drop the print speed by about 20 % or raise the nozzle to 220 °C.

Ripples beside sharp corners: This is motion, not filament. Lower the outer wall speed and leave inner walls and infill fast.

Warped corners on long flat parts: Wash the plate with warm water and dish soap, raise the bed to 60 °C and slow the first layer to 20 mm/s.
