💡 Hint

Common Mistakes

Using a value too large or too small for the printer's bed size.

Confusing feed rate with position.

The command G1 X50 F1500 moves the print head to X=50 at a feed rate of 1500 mm/min.

💡 Hint

Common Mistakes

Setting temperature too low or too high for the filament.

Confusing M104 with other temperature commands.

The command M104 S200 sets the extruder temperature to 200°C.

💡 Hint

Common Mistakes

Using movement commands instead of homing.

Confusing temperature commands with homing.

The command G28 homes all axes to their origin positions.

💡 Hint

Common Mistakes

Using different temperatures for setting and waiting.

Confusing bed temperature commands with extruder temperature.

M140 S60 sets the bed temperature to 60°C without waiting.
M190 S60 waits until the bed reaches 60°C before continuing.

Fill all three blanks to create a dictionary of axis positions where keys are axis names in uppercase and values are their coordinates, but only include axes with coordinates greater than 0.

3D Printing

positions = { [1]: [2] for [3] in ['x', 'y', 'z'] if [2] > 0 }

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using lowercase keys instead of uppercase.

Not filtering axes with coordinates greater than zero.

Mixing variable names incorrectly.

This dictionary comprehension creates keys as uppercase axis names and values as their coordinates from the coords dictionary, including only axes with positive coordinates.
