  2. Right click on the parent folder, select “Open in terminal”

  3. Execute the script

  4. Transfer .gcode to your printer using the sd card

  5. Manually set the z height to ~10cm

  6. Execute the gcode

python generate_unspool_gcode.py --unit g --total 100 --step .5 --x 110 --y 110 --speed 500

=> Generates .gcode that will unspool 100g of filament in .5g steps at 500mm/min speed on x=110 and y=110.
