I was able to write a script in python that does what I want. Posting it here for others to reference if needed.

import sys
import re

flag = False

out = open('YOUR FILE NAME HERE'+'_adjusted'+'.gcode', 'w')

with open('YOUR FILE NAME HERE.gcode') as f:
for r in f:
if re.search('G1 F', r):
feedrate = r[3:]
flag = True
print(r[:-1] + ' ' + feedrate) # get rid of new line
elif flag:
r = r[:-1] + ' ' + feedrate
out.write(r)
flag = False # Reset flag
else:
out.write(r)
flag = False # Reset flag

Yeah. From what I can gather. I need to write a script to go through the entire gcode and automate moving the feedrate to the end of the following line. I am going to try to write it in python, but its been a while.

The machine uses a yaskawa controller and apparently how it interprets the gcode is part of the firmware. No way for me to change anything in there. The slicer firmware is RepRap/Sprinter.

I am looking for help with writing a post process script to adjust the formatting of the feedrate call outs from PrusaSlicer.

Right now the format is like this:
1 G1 E.1 F2400
2 ;TYPE:Skirt/Brim
3 ;WIDTH:1.7
4 G1 F4799.988
5 G1 X487.836 Y463.711 E.82895

But this causes issues where my machine doesn't recognize the G1 F4799.988 command and maintains the feed rate of F2400 from line 1.

I need it to look something like this (which comes from Simplify3D, but I want to use organic tree supports).

6 G1 Z0.900 F1800
7 G1 X483.600 Y469.844 F21000
8 G1 X490.044 Y463.400 E4.6282 F3600
9 G1 X549.956 Y463.400 E35.0570

Any help would be appreciated.
