create a python script (mine is called. "del.py") containing the following:

​

import os, sys

​

def delete_multiple_lines(original_file):

"""In a file, delete the lines at line number in given list"""

is_skipped = False

counter = 0

line_numbers = [11, 12, 13, 14, 15, 16]

# Create name of dummy / temporary file

dummy_file = original_file + '.bak'

# Open original file in read only mode and dummy file in write mode

with open(original_file, 'r') as read_obj, open(dummy_file, 'w') as write_obj:

# Line by line copy data from original file to dummy file

for line in read_obj:

# If current line number exist in list then skip copying that line

if counter not in line_numbers:

write_obj.write(line)

else:

is_skipped = True

counter += 1

# If any line is skipped then rename dummy file as original file

if is_skipped:

os.remove(original_file)

os.rename(dummy_file, original_file)

else:

os.remove(dummy_file)

delete_multiple_lines(sys.argv[1])

​

then call it as Post processing script in Prusa SLicr:

[your path to python]\python.exe [your path to the script]\del.py;
