💡 Hint

Common Mistakes

Setting the first layer height too high reduces adhesion.

Using the same height as other layers can cause poor bed contact.

The first layer height is usually set lower, around 0.1 mm, to improve adhesion by allowing the filament to stick better to the print bed.

💡 Hint

Common Mistakes

Printing the first layer too fast causes poor adhesion.

Using default or high speeds can lead to warping.

Slowing down the first layer speed to around 20 mm/s helps the filament stick well to the bed by allowing better placement.

Fix the error in the code to set the first layer extrusion width for better adhesion.

💡 Hint

Common Mistakes

Using too low extrusion width causes gaps and poor adhesion.

Setting extrusion width equal to nozzle diameter may not be enough.

Setting the first layer extrusion width to 200% increases the amount of filament extruded, improving bed adhesion by creating a wider line.

Fill both blanks to set the first layer temperature and bed temperature for better adhesion.

3D Printing

first_layer_temperature = [1]
bed_temperature = [2]

💡 Hint

Common Mistakes

Setting temperatures too low causes poor adhesion.

Using the same temperature as other layers may not be effective.

The first layer temperature is often set higher, around 70°C for the nozzle, and the bed temperature around 110°C to help the filament stick well.

hard

Fill all three blanks to set the first layer fan speed, skirt line count, and initial layer flow rate for better adhesion.

3D Printing

first_layer_fan_speed = [1]
skirt_line_count = [2]
initial_layer_flow_rate = [3]

💡 Hint

Common Mistakes

Using fan speed too high cools the filament too fast.

Not using skirt lines can cause poor extrusion start.

Setting flow rate too low causes weak first layer.

Turning off the fan (0%) on the first layer prevents cooling too fast, using 3 skirt lines helps prime the nozzle, and increasing flow rate to 110% ensures good filament extrusion for adhesion.
