Clean the debris inside the machine to ensure that its operation is not affected.
Check if the wire output is normal, if not, please check if the extruder is blocked.
Check the nozzle for filament residue, if so, heat the nozzle and remove it with a tool.
Check the surface of the platform for residual filaments and glue, if so,
clean the surface of the platform.
XYZ optic axis lubrication.
Replace the nozzle.
Axis movement.
Optimization of vibration veins.
Auto Leveling.
Replacement of filaments of the same kind: follow the normal Retreat - Feed process.
Replacement of different filaments: Preheat the nozzle to reach the target temperature
of the current filament; then retreat it, replace with the target filament, and preheat the
nozzle to the higher filament extrude temperature of the two filaments; feed for 30s
until the filament has been completely extruded, and finally set the nozzle temperature
to the temperature of current filament nozzle.
